Half way there. Got it all back together. I've swapped in a K&N. Done the airbox venturi mod, relocated the breather outside of the airbox , and rejeted to 45/175, and 2.25 turns on the mixture screw. MAN WHAT A DIFFERENCE. It is significantly more confidence inspiring pulling onto the highway. A heck of alot more "get outta the way" on tap. I've got a bit more tuning to go though. At 70-75mph I think I'm getting detonation ... help me understand what that feels like I know the theory. I hear a pop (not scary loud) and it stops pulling for a second. Then it carries on for a while pulling quite well. Somethings I will get 2 or 3 in a row. Is this detonation? If it were too rich instead of too lean would I have a different symptoms at this speed? Should I back out the mixture screw another half? I'm not wanting to melt or break anything and I'm guessing that backing out the screw will richen it up. | ||

Blue, I had one that did the same thing, I would get a pop, then every so often it would feel like it was loosing power, but just for a second, finally it started dying on me. I was an ignition module. | ||

Sounds like a bad module to me too. PS please at least fill out the year, mileage and any modifications to your Blast in your profile. It makes it much easier for us to help. | ||

Sorry Gents. I thought I had all of this stuff in my profile. I'm not at all against upgrading the ignition module. still it seems strange that this would show up so significantly on the test ride after all of these other changes. On my M2 it was a 5 minute job to swap in the pro series unit. Anyone got remember the price of a replacement stock unit and the effort level associated with swapping it out? The upgrades that I saw on both Buell and American Sport Bike web sites look like you have to get inside the cam position sensor cover to work on this on a blast. | ||

The price of a stock module including shipping from Stone Mtn. was $124. The installation requires removing the tank to get to the wiring harness plug and reusing the harness plug. About 1 hour working slowly. If you static time it, you use the TDC mark (The Line) and set it so the LED on the module goes off when the TDC mark centers in the window. | ||

Blue02M2, Swampy is right on the money, It takes about an hour to change it out working slowly. I didn't have to remove the tank, but you will have to remove the tank cover, and the air scoop on the left side of the bike. Before you go through the trouble check out your other switches and make sure that they are working properly. And that your fuses are in good shape and not corroded. A loose kickstand switch or kickstand spring can cause a similar problem, and so can a bad tip-over switch. It also could be intake related, like a torn intake boot, but it sounds electrical, kinda like you were going down the road and turned the kill switch on and off really quickly. James | ||

Blue02 M2- Please accept my apologies. I thought your profile was complete, but thought I was mistaken. Turns out my profile is now empty too showing a total of 12 posts!!!!! EZ Do You Know Whats Up With That? PS If you do need an ignition module and you are going to do more performance upgrades it might be worth it to get the Screamin Eagle module. (It is double the price, but can be found for less than that. It also gives you an easy way to hook up a tach). | ||

Where do I find this Screaming eagle unit that the you speak of? Is it a sporty unit? What are the spec's/part numbers? | ||
| Ezblast |
Yes - for sportsters and the Blast - any dealer should be able to pull it up for you! GT - JBOTDS! EZ | ||

ok guys help me out. I ordered the pro series intake and the dynojet jet kit today.am going to order pro series exhaust this week.was just looking at the dynojet website and their directions say to lean the jets down to 155 main with aftermarket airbox and exhaust.that is the exact opposite of what is here.on the 2005 blast if I goto 175 main will that cut it? or do I need to lean it as dynojet says?HELP!!! | ||
| Gearheaderiko |
Dyno jet uses a different numbering system. Use the Dydnojet suggested numbers. | ||

I accidentally unscrewed the main pilot jet and the the longer brass tube that main pilot gets screwed in (does that make sense?) It is brass colored approximately an inch in length and it has tiny holes on the tube (emulsion tube?). Anyways, the question is, when I uscrewed the whole thing, a silver tube piece dropped also, its about a lil less than a half an inch and it has a ring around it..one end has a bigger hole than the other--which end goes in first?...the bigger end hole when screwed in along with the other piece--goes in a little deeper than the other end--but both ways--the whole thing does not screw in flush to the carb--is this normal?. I noticed that the only way it screws all the way in is if you leave out the silver piece. Now i'm not sure it came from the main pilot jet mechanism. I hope that makes sense--thanks for the help in advance. (Message edited by Mataleao on August 28, 2005) | ||

jugallo, I noticed in another post that you had a brace made for the carb with aftermarket intake. How much did it cost you an how would I go about getting one? | ||
| Jugallo94 |
tnt, yes I had a brace made by spiderman. You could contact him, or if your fabrication skills are good make one yourself. I will be posting pics this week of the recent mods. If you want I can send you some pics of the bracket monday night. The only thing to make sure with the bracket is that it secures the carb. | ||
| Jugallo94 |
tnt I posted some pics of the bracket in the pics area. If you want some with more detail let me know. | ||
| Tnthumper |
jugallo, thanks looks like I should be able to do something like that pretty easy. | ||
| Swampy |
Yes, How did you attach the bracket to the carb. Can you give us a close up of that? | ||
| Ezblast |
Guys - I've been there and done that - I'm betting the boot lasts about 500 miles - sorry. Mat - see the online manual for the carb parts break down. GT - JBOTDS! EZ (Message edited by ezblast on August 30, 2005) | ||
| Jugallo94 |
I will get a better pic of that when I get home from work tonight and post it. I got over 2,000 miles on the original boot without a brace, and have close to 700 miles since the brace was put on with a new boot. | ||
| Ezblast |
Its the same style brace Tony and Ray used - of course you may or may not get more miles, but its still not going to last any where near stock life. GT - JBOTDS! EZ | ||
| Jugallo94 |
this is how I mounted the bracket to the carb  | ||

guys, I should have my pro-series intake and re-jett kit this week and exhaust in 2 weeks.will it be ok to set up carb for both aftermarket intake and exhaust for a week or so and final tune when I get exhaust on it?I think I would be running rich but would that be a major prob? | ||
| Gearheaderiko |
No, you should be fine. I ran mine that way after putting it briefly back to stock to pass salvage inspection. I certainly wouldnt put a lot (1000+) of miles on it that way though. | ||
| Tnthumper |
thanks gearhead.should not be more than 400-500 miles.just want to get as much done in one sitting as possible | ||
| Tnthumper |
I got my pro-series intake today and my dyno-jett re-jett kit. Has anyone tried using exhaust clamps on carb and engine side and metal bars underneath as a brace to hold weight of carb after removing stock airbox? Just an idea. I am going to have leftover aluminum angle after mounting driving lights and thought I might see if I could make it work. I will try to post tomorrow to tell if it works. | ||
| Ezblast |
Yes - sigh | ||
| Tnthumper |
Ez, sounds like that idea did'nt work too well. I'll try to rig up something like Jugallo94 has. something has to be better than nothing. |
