Dayuum. Had to pull the heads back off due to contact between the fins of the larger 1250 cylinders and the Buell push rod boxes. I spoke to Dan at NRHS who was kind enough to inform me that it would be necessary to grind a little off the bottom few fins for each cylinder. To gain about .10" all around the pushrod boxes, it was necessary to grind a portion of the bottom 6 fins. No worries tho, it still has considerably more finage that the stockers. If you look closely, you can see where the fins need to be cut. Maybe this will save some BadWebber from having to pull their jugs back off, like I did.  With the fin issue resolved everything went together quite nicely. Man I love these Micron pipes.  It even looks like skully likes the pipes too!  I do believe he is smiling....sort of. I know I am.   Well, here she sits. Patiently waiting for the UPS truck to drop off her newly mapped ECM from the Almiester at American Sport Bike. Thanks AL! You Da Man.  | ||

So where exactly do you plan on mounting the 50lbs bag of lead shot on the front fender in order to keep the front end from becoming permanently affixed to the sky.  I like the idea but can't for the life of me figure out why you would need any more power than is already there. I've only got a race pipe and ECM and I can barely keep the front on the ground in 1st or 2nd gear. | ||
| Chadhargis |
I can thing of several areas where I'd like more power.... 1) When passing a line of slow cars on a twisty road 2) Coming down the front straight at Nashville Superspeedway...120 about the best I can do 3) Coming down the front straight at Barber 4) Coming down the back straight at Barber LOL!  | ||

Chad, Your problem is wind resistance on that ginormous frame of yours; not lack of power.  As for more power, I have never had any trouble passing any car at all. I do like the skull, the pipes, the bark busters, the bar-end mirrors, and the F150 though!  | ||
| Red_chili |
Try riding up here at 6,000 ft. Your front wheel will stay much more planted.  | ||
| Chief |
Chad the answer to number 2,3,4 would be gearing. You could have 500 horsepower but with the current redline, transmission gearing and front and rear sprocket size 120mph is about all you get. You may get there a lot faster with more power assuming you can keep that front end down but your still gonna hit a brick wall when the rev limiter kicks in. | ||

I am just trying to get the Buell to keep up with my softail.  It kinda sucks that a 700 pound harley pulls better than my 425 pound Uly. The 10 pounds of boost may have something to do with that, though.  Notice that Skully has the same grin! It's not all about horsepower. It's more about grin factor for me. I can't leave anything alone. I didn't tear down a perfectly good bike just to go to 1250 and ported heads. My power was a little off, and I discovered that a leaking intake valve guide design was the culprit. Since the motor had to come apart to fix it, I figured WTF and went for the fresh heads and oversize cylinders. I don't know what the power will be like, but I do know the $#^*ing valve guides wont leak.  | ||

It's people like you that make me SICK!!!! With anticipation of the test ride  | ||
| Rotorhead |
Where did you get skully?!!! Got to have one!! He does have an evil little "Mona Lisa" grin like he did something bad and want's you to know all about it. | ||
| Johnny_uly |
I like it so far! | ||
| Treadmarks |
Thanks guys. Man o man o man...I wish that map would hurry up and get here, other wise I might jes rub all the ceramic of of these pieeepes.  Rotorhead, Skully is from the skullman online. The blackout highlights are from engravers enamel. pimpin mah ride, from da inside out.  | ||
| Etennuly |
Well hopefully when she breaks in again, at least you'll have enough power to run the Death Rays!  | ||
| Paochow |
Very cool. You are definitely the king of farkles. | ||
| Jmhinkle |
Tread, is that some sort of heat tape on the right side frame? Did you install it? What is it made from? Does it help even a little? Very nice mods you got goin' there. Still love the DeathRays! | ||
| Sweatmark |
Tread - what type of head work did you get done? Stage 1/2/3? Any issues with the motor build besides the required grinding for pushrod housings? Thanks, Mark future 1250er | ||
| Treadmarks |
Jm, That is a foil backed ceramic matting that is used as a heat barrier. I forget the brand name, but I installed it on the bottom of my XR650 tank and lowered the fuel temp by 20 degrees. We will se how it does on the Uly.  Sweatmark, NRHS stage 1 CNC porting, with AVS bullet guides and seals. Intake:  Exhaust:  The clearance for the pushrod housings is the only issue so far. I didn't want to go to radical on the ports, as Al at American Sport Bike has maps for the 1250 with the stock heads and I really didn't want to get into all that remapping. | ||
| Etennuly |
That is well thought out and well executed work there. Might I ask where you found the ceramic matting? That too seems like an excellent idea. | ||
| Electraglider_1997 |
Check this stuff out. http://www.pitstopusa.com/detail.aspx?ID=64806 | ||
| Jmhinkle |
That foil ceramic matting is exactly the kind of stuff I have been trying to find. Where did you get it? I've tried different forms of the thick tape stuff and it never seems to help really. The stuff Tread found looks great for the job. | ||

I don't know how much time it took to get the top end fitted. I don't know because at the time, I really didn't care. You see, I live for this sheit. I enjoy working on and riding everything I own. I don't know if the cylinders are Chinese or not, and I really don't care. They look more like punched out EVO units to me, but what do I know. As far as Axtell or Revolution Performance 1250 Buell cylinders go... I didn't know you installed a 1250 kit from them on your Uly. Please feel free to share your installation experience and results with us-in your own thread. This is my first Buell, and my first big bore install on any V-twin, so I just kind of roll with the punches and learn as I go. I have learned that there are only 3 people that I consider knowledgeable and experienced enough for me to trust to buy parts from them, and you just aren't one of 'em. I have read the writings and spoke with Al at American Sport Bike many times, and consider him a valuable resource to the Buell performance community as well as a pioneer and contributor to the aftermarket segment. Dan (the Buell man) at NRHS owns 5 Buells and has devoted considerable resources into the Buell performance and racing history. Both Al and Dan vouch for Terry's Buell tuning expertise and that's where the maps were developed. As far as the American made and American engineered goes....You would be surprised at how much equipment on the market today, comes from the lowest cost provider. And when it comes down to being the lowest cost provider, America just ain't it. American Engineering....Gimme a break. Look at a few forms of Buell Product Selection through Engineering-cooling fans, rear wheel bearings, freaking valve guide seals, side stands, headlight reflectors, triple clamps design, ignition switch placement, pinging, Uly handguards...bla bla bla..you get the picture. They don't even put American Motorcycles on the logo any longer. I don't mean to offend anyone or come off as d$&k, but where I come from it ain't exactly polite to tell someone that the product they chose to repair their broken American Engineered motorcycle is inferior because it may have been made in China. But what do I know. | ||
| Dentguy |
Treadmarks... The Uly is looking great, can't wait to hear how it runs. Also, who makes the supercharger on the softail? | ||
| Treadmarks |
Jm, I think I got the heat barrier from Moose racing for my XR, but here is what it is: http://www.pegasusautoracing.com/productselection. asp?Product=1828 | ||
| Treadmarks |
Thanks Dentguy. The supercharger is a Rotrex C15-60. http://www.rotrex.com/ Kit kit is a woody, which is no longer available. | ||

Tread Thanks for that link. That is the stuff I was looking for. | ||

Whooo Hooooooo Fired up the red eyed armadillo today and I must say holy cow. I can't believe after sitting so long (I can't remember how long it has been) one flick of the start switch and boom biddy boom biddy boom. Dayum I missed this bike. Gave it about ten minutes at idle with a powerful fan blowing on the front of the engine while I checked the tires and looked for any leaks. (Note to self: never look directly into the deathray...  ) Took it for a nice easy 8 mile ride to fill it up with fresh fuel and get re-aquainted. After spending a couple of months on the softail, it was refreshing to remember how sure footed the Uly is. Points of interest: The micron sounds like a thunderstorm at idle. The ceramic coating on the pipes actually helps with the heat on the leg in traffic. The heat mat on the frame seems to help as well. Without the right side scoop (it won't fit with the micron) the fan runs while riding. Off idle torque is way up. Midrange power is up as well. Idle is much improved and rock solid at 950. I haven't noticed any drawbacks as of yet. The headwork, bore increase, micron and the American Sport Bike map seem to be a good match for each other. Header coating and heat barrier on frame surely helped with heat management. I will switch back to conventional motor oil and go through another break in for the fresh heads and cylinders. I will put Odie's blankets back on for an even cooler ride.  | ||

So...will that bike be making any appearances at whatever they call fuddruckers now for bike night? I went last week for the first time in forever. I gotta see that bike in person. | ||
| Treadmarks |
Hey Miamiuly. We should get together there, I live about 10 minutes from ruckers. I used to go regularly, but it got to where nobody was speaking Engrish anymore so I stopped going. I can aim for next Thurs I you wanna hook up. | ||
| Miamiuly |
sounds good, we'll aim for thurs. | ||

"I don't mean to offend anyone or come off as d$&k" You can say "dick" here. Not sure why you saw fit to get all personal. My take is that you were warning folks against the interference/fitment/grinding issue concerning your new 1250cc cylinders. My intent was to provide clarification, that the issue you warned about applies specifically to the Chinese made NRHS cylinders, not Axtell cylinders or Revolution Performance cylinders, which are made in America. I'm a bit surprised that you didn't know that the iron sleeved cylinders you bought were made in China. Though understandably that's information that the seller would probably rather not advertise. For the record, I have been advised by Aaron Wilson of N R H S that these cylinders are definitely not of Chinese origin--rt Not sure how you imagine I was intending to insult you. Whatever. I personally don't need to install Revolution Performance or Axtell 1250cc cylinders on my own Uly to know with utmost certainty that they bolt right up to all the Buell XBikes. Plenty of other folks have done so. I don't sell parts. You are free to take advice from anyone you like--Al is an excellent choice--and you are free to purchase your parts from the lowest cost provider as you wish. Did your esteemed advisor at HRHS inform you that machining material from any cylinder anywhere after they are bored and honed is a very bad idea? A competent advisor would have warned you that doing so puts at risk the integrity of the bore geometry in the affected area. At a minimum they would have asked that you take some careful bore measurements before and after to find how much the bore geometry was affected by the machining away of significant portions of the lower six fins and to verify that it remained within acceptable tolerances. But hey, what do I know? I'm not fortunate enough to own a Uly.  (Message edited by road_thing on September 17, 2007) |
