Nuts, A bit of valve adjustment on your part and your whiff of smoke might just disappear. You did all the work so you get to take all the credit on this one. You won half the battle today and hopefully with the bit of tweaking tomorrow will finish of the mechanical issues. Get the wheels relaced and trued, new tires and we are going on an epic adventure. O.K., maybe not epic but an adventure nonetheless. The right hand fork of Wildlife Rd. is beckoning and taunting us  . We must show it that we are the master of our domain!! | ||

Torts, thanks for the invite you posted in Carolina Corner Carvers. Sounds interesting.  | ||

Nuts& Jackie, GOOD JOB, glad things turned out minimal. That bike should give you many hours of fun. After riding the Yam for a few days your going to notice just how heavy that Uly really is. Go have some fun young'n........Charlie | ||

No fun today. I refilled the oil after setting the valve tolerances. I took it outside to let it run a while and couldn't get it to go. It turned over and fired several times but wouldn't stay running. It would only crank on half choke and would die regardless of throttle inputs. A bit frustrating. I lubed the clutch cable and that seems to be alot smoother. I really need to get it running before I dump any more money into it. Wheel help will be put off until she's a solid runner. worse case scenario I can take it over to the shop I use for tires and let Scott have a looksee. He has the same bike just about 10 years newer. Thanks for the vote of confidence Charlie. NUTS | ||

Nuts, You may have picked up some trash in the carb. from the tank. Do you have a gas line filter or just whats in the tank? Make sure the tank is clean and the vent isn't stopped up( start it with the cap off) Try draining the carb first, but you may have to go back thru it again(pilot jet) real easy to stop up. If it ran ok the first time, it almost has to be trash somewhere........Charlie | ||

Charlie, I rode over and helped Nuts get her going again. The intake manifold was missing a plug to block off air intake from where one of the smog hoses would have went. As soon as I put my finger on it she fired up. Take my finger off and she died. An easy fix. We then went to work adjusting the valves and all went well. She fires right up but is running WAY lean with the pipe turning cherry red and the exhaust valve pinging on occassion. Went to set the a/f screw and idle and noticed the fuel screw is not there! Got Nuts to plug it with his finger and it was pulling a vacuum. I am assuming this has at least something to do with the lean condition. The intake manifold also has some signifigant dry rot (made of rubber) and cracks which could theoretically be letting in additional air as well. At this point I think until he gets the carb rebuild kit and new manifold we are at a standstill. We did not have a compression/leakdown gauge so we did the ole' redneck test of pulling the plug and blocking the hole with my finger. The compression seems great (blew my finger completely free of the cylinder) but still don't know about leakdown. Overall it seems to be mechanically sound just needs some TLC and garage time. Can you think of anything we may have overlooked? | ||

Jackie, The air screw would be enough to do it. Normal setting is around 3/4 to 1 1/2 turns off stop. A new manifold would be wise, but the air screw is probably the culprit. The hose that came off the fitting on the manifold is probably to a boost bottle(gives bottom end power)should be a hose that goes straight to a plastic canister usually mounted under the tank above the motor.You can run without it if you block the hole in the intake, but will have more power with it..........Charlie | ||

You may have picked up some trash in the carb. from the tank Hey, now, I had nothing to do with it. But I agree with eliminating the trash in the fuel system. It has caused me many(well a couple) headaches before. What do you mean "there is factory stuff missing"?? I thought that was the norm on a used bike. How much depends on how old it is. In my case, it's not that old, but it has lots of hours. Stick with it Nuts(and Jackie). It can't be but so bad if you already heard it run. What was that vacuum line for, anyway??

Charlie, I assumed the nipple on the intake was there simply as a byproduct of Yamaha using the same manifold for California and non California models. In all honesty I have never heard of a boost bottle. I checked the schematics and it simply calls for a plug on non Ca. models which led to the assumption that it was smog reduction related. As I am sure you know the carb is a Mikuni so parts should be widely and cheaply available. I suggested he get it professionally rebuilt if the fee is minimal. I can do it and have done it before but this way he is assured it will be back to factory specs. I did make the suggestion he go up one jet size though. I figure they probably come from the factory lean in the first place and if it comes back too rich just throw in a Unifilter and desnorkel to compensate. What do you think? | ||
| Cyclonecharlie |
Jackie, Your probably right, boost bottles where a product of the eighties and mostly two stroke. I installed one on the 360 Yam.(74 two stroke)we are building for the track.This was original developed by Yamaha and then Suz.& Kaw. jumped in. The way it works is,it captures fuel that is blown back towards the carb.when you close the throttle.(vacuum)Any time flow goes past the needle(either direction) it picks up more fuel and changes your A/F ratio, then you get a lag when you get back on the throttle.Boost bottle eliminates that lag and releases that stored charge at the right ratio when you go back on throttle(no vacuum). Yamaha's official name was YEIS (Yamaha Energy Induction System) Any way, if you can find an old carb. the needle might be the same. A good place to check would be Cycle Shack, down on Williamson Rd ( close to Civic Center)Scott is an "Ole road racer"and has always been pretty helpful to me.......Charlie | ||

What the heck is going on at Va. Tech??????? News down here said 20 people shot dead. Arrested one shooter, looking for more. Anybody in Roanoke know anything?....Charlie | ||
| Nutsosane |
Turn off the TV and wait until tonight for official news. As of right now its a whole lotta filler. nuts | ||
| The_raven |
you guys are killing me. I have done nothing productive at work today, except for locate several dr's that look mighty attractive. Peer pressure, gotta love it. seth | ||
| Luvthemtorts |
Charlie, A whole lot of craziness is going on up here. Seems the death toll is over 30 now but who really knows this early. I hate that the news just takes these things and turns them into a feeding frenzy. Hopefully we will have at least a bit of truth by tomorrow. The boost bottle sound like a neat idea. Kinda reminds me of the "spark enhancer" that they used to sell for dirtbikes years ago. It went between the coil and plug and was supposed to insure complete combustion. I honestly can't say whether or not it did but the idea seemed sound at the time. So what do you think of the idea of going up one jet size? Raven, Nuts is creeping closer to having a good runner so you better speed up the search. Discussions of suitable and exciting routes are currently in the works and may spill over to the coal roads of W.V. | ||
| Cyclonecharlie |
Jackie, You won't know if your really lean until you get an air screw in it.And when the pipes got red, you weren't using the main jet.If you want to play it safe you can go up one size and carry an extra plug.It may be awhile before Nuts starts using the mj anyway.  That Va Tech thing is looking scary....Charlie PS... Unlike the spark thing, the Boost Bottle really does work. Do you remember the power valve on the exhaust? That worked also. | ||

Dangit... Here's the chance to lower the "stien" on the cheap, and I don't have the cashola. Ebay low forks Ebay low rear shock | ||

Charlie, I was actually talking about going up one size on both pilot and main jet. From what little research I have done on his bike it seems this is a common mod since they come from the factory pretty lean. My reasoning is it will save him some time since I am sure once it gets going he will do the air filter, snorkel and perhaps exhaust mods to wring every bit of performance he can out of that sucker  . The problem with just replacing the air screw is since it is located in a down position I seriously doubt that the spring and O ring are still in place. Also, while he was cleaning the carb he sprayed cleaner directly into the carb body without removing the rubber diaphram and seals. Could be bad news for rubber parts that have already cracked from sitting around. Honestly I think the best course for him is to get the carb inspected and rebuilt by a shop since they have all the equipment/supplies on hand. That way when he chucks it back on the bike he can rule out carb failure as a whole and move on to the next likely culprit. I personally think after spending some time with it that a carb rebuild will cure the vast majority of his woes. | ||
| Cyclonecharlie |
Jackie, I'm not familiar with that carb., you say it has a diaphram ? If it is a pumper carb. then I totally agree with you(too much in there to mess up)Was the air cleaner and exhaust stock? Dirt bikes have changed alot since I was heavy into them(60's 70's& a few of the 80's) And now what I work on is still bikes from that era(Vintage) Get a price on a rebuild and then price a new carb. on line.....Charlie | ||
| Luvthemtorts |
Charlie, The air cleaner and exhaust are stock. It is not a pumper carb. The diaphram I am referring to is actually the rubber sleeve that the needle slides into. I could rebuild it for him but think that if a professional mechanic does it then it will completely rule out any error on my part should a problem arise upon reinstallation. So are ya'll running 2 strokes down there? I personally hated the mixing and reed valves but LOVED the sound they make when hammering them hard. | ||
| Cyclonecharlie |
Jackie, Right now I have (3) 2 Bultaco's and 1 Yamaha. Only the Yamaha has reeds, the others are piston port. They are much cheaper to build and maintain than the four strokes. I don't mind mixing the gas (12 bucks a gal, last years price) not counting the caster and other additives(secret)LOL I love the smell of the caster(bean oil) The whole thing is very addictive, I need to get you guys to a race sometime.....Charlie | ||
| Luvthemtorts |
Charlie, Now that I actually own a bike that I don't care if it gets wet, dirty or scratched you very well may see us in the not too distant future. Ya'll got any sandy unpaved roads to explore down there? If we time it right we could go riding AND look for creepy crawlies! I am actually giving very serious thought into going to a little get together in W.V. towards the end of April. Trailer the bike over there on Friday, ride Saturday and then home Sunday. I will admit I am a bit concerned about going by myself and hanging out with people I don't know. As you all know I can come across as a bit abrasive even though I generally mean nothing by my remarks. What if I get down there, mouth off and then get beat up by the in crowd  ? As far as two strokes go, we used to run a Yamaha 175IT when I was growing up and we thought that thing was the holy grail of motorbikes. It would consistantly beat the crap out of our XR250's and once you got it wound up was a recipe for MASSIVE air. We had this one jump that only me and one other fool were stupid enough to jump. Get that sucker going 45-50MPH and sail over a group of pine trees. The landscape provided a natural elevated landing ramp on the other side which made the jump possible. Without it or come up short you were going to drop 25ft or so. Luckily neither of us bailed on that one. My buddy did manage to run smack into a tree right before taking off when he got a bit sideways and decided to pull the plug. Bent the forks in an impressive fashion and sent him on a superman like flight over the handlebars. AHH, I long for the days when I was immortal ! | ||

The carb is in the shop awaiting parts. Turns out the fuel screw is there, just hidden. I have a few spokes on their way too, for the rear. Everything should be in by next Tuesday and I'll be out wreaking havoc soon enough. NUTS | ||

Nuts, See what you think of this route. May be a good "close in" run for our first voyage. http://www.roanoke.com/outdoors/biking/trail/wb/wb /xp-4821 | ||

Got my box from andy today... Waiting on tools sucks. Still waiting on the box with the surprise. Suddenly, tonight, those amber wheels don't look so undesireable, since they are near-new, and I have a box-o-stuff to outfit them with. Doesn't look like the front rotor was bent after all, I think it was the wheel. | ||
| Luvthemtorts |
Tank, With all this dual sport talk are you getting any wild ideas about fixing up the Bolt' and getting a dual sport? It appears there is much fun coming up in the near future! So what was in the box and what is going to be in the surprise box. Come on man, you can tell me. I won't tell anybody  . | ||
| Tank_bueller |
I'd love to have a dual sport(with the emphasis on "sport"). I really can't justify a bike like that here, though.  As for the first box, I got: front rotor kit(w/hardware) rear rotor and bolts EBC pads f&r new coil(just in case) NGK plugs for both bikes traction grips a couple oil filters a couple drain plug o-rings ..and a whole bunch of bolts/screws/washers to replace the ones that are missing, and in case I find more missing. Second box..... ok, here's a hint....  | ||

Tank, Rear pulley? Nuts, You'll get a kick out of this. I got home from ball with my head pounding even worse after two hours of screamin' at 22 girls trying to play softball. Anyway, walk through the front door, go to get something to drink and here comes my mom messing with that damn stove. BEEP, BEEP, BEEP, BEEP and I'm about to lose it. Kids let Jasper loose and she jumps up and hits me in the satchel at just the right angle to induce extreme nausea and now I'm really going crazy. I go sit on the front porch to get some air and calm down and before I know it the Ole' lady breaks out the 1943 smoke o' matic mower figuring the lawn needs trimming RIGHT NOW. Thought I was going to stroke out right there on the spot or at least have a grand mal seizure. Anyway, I thought you would enjoy my agony since I bailed on you this morning. | ||
| Nutsosane |
That is a delightful story Jackie. Sounds like you were foolin with Mr. Murphy and his law again. I bet you'll be giving second thoughts to bailing next time. Beep, beep, beep, beep; "This clock won't set, lemme try again, beep, beep, beep..." Tank, I'm betting it's a Vortex front stand. NUTS | ||

Nuts, After looking at the diagram for the cam chain tensioner something doesn't seem quite right. For one they show a gasket which means it has been removed before and secondly they show it as one sealed unit instead of several replaceable pieces. If you ain't too spent after work tomorrow I'd like to head over after ball to have another look see. On a bright note it isn't an expensive piece if you decide to replace it. | ||
| Tank_bueller |
Dang, Torts, I thought I had a rough day. Everything I touched required 3 times the normal input... But I didn't get "Nutted". Bwaaahaa.  Tank, Rear pulley? Close, but it aint no "pulley". You were right, Saintly is a stand up dude. Tank |
