Primary Chain: at 1,000 & at every 2,500 mi. interval thereafter. The Blast is shipped with a spacer between the primary chain limiting screw and the locknut. The spacer is discarded at the first service interval. A inch-pound torque wrench is used - Tighten chain limiting screw to 24 in/lbs Back-off chain limiting screw 3/4 turn- 41/2 'flats' Practical note: 3 to 5 flats more (8 flats out from torque spec is usually golden)is the experienced recommendation by many. Hold chain limiting screw while tightening jam nut. Too loose - that box of rocks sound Too tight - your top end drops to a max of like 65 and it will throw your idle off and you'll stall out. So if this happens after your first service - this is one of the possible reasons. Well thats all there is to it - the tool would pay for itself by the fourth adjustment - so its up to you - I got one though and like all tools you'll find other uses. The following method though not recomended is used by many - Can this be done without a torque wrench? To answer your question, Yes. From a cold start, let the bike get to a warmed up idle, then start tightening the primary chain. When you hear the idle start to drop, back off two flats. I've been doing it this way for the last few chain adjustments, and it is usually wthin a flat of adjusting it with a torque wrench. BTw, the reason for a cold start is to set the chain tension with a cold primary. (Note:A hex nut has six sides, six flats, 1/3 of a turn is 2 flats.) Got Thump?! Just Blasting on the Dark side!

Question. Is this necessary if you still have your spacer? To ephasize my ignorance, is this bolt located right next to the transmission drain plug? | ||

It is necessary, and It can't be done without removing the spacer. The adjustment screw is located right where you think it is  ">. Tightening the chain on the loose side of spec (I use one turn out) keeps the vibes down, and helps shifting. You can adjust it close by eat, tighten the chain until a cold motor idling on the enrichener starts to bog, then back off until the idle come back up, then two or three flats more. Close enough without a torque wrench. James edited by jprovo on June 24, 2003 | ||

BTW, You'll be suprised on how much slack you pull out of the chain after you ditch the spacer. I probably adjusted 1/4"-3/8" of slack out of mine on the first adjustment. Oh yeah, if you haven't noticed the spacer is slotted, so all you have to do is loosen the adjusting bolt and slide the spacer out. James edited by jprovo on June 24, 2003 | ||

I am experiencing a dragging when operating the Blast at a steady throttle, it seems like a binding in the trans or primary, the engine doesn't bog, it is a real short event that jerks the bike. I ruled out carb by changing carbs, plug looks good. I don't think it is engine related. I changed the primary fluid, and adjusted the primary chain but still no fix. I at first suspected the drive belt riding up on the pulley but that doesn't appear to be the case. The bike just turned 3000 miles. It seems almost like the clutch is slipping but it doesn't slip under load. Any ideas? Could I have put too much trans fluid in? edited by swampy on August 15, 2003 | ||

In a level place check and see - oil should be touching but not past the bottom gear teeth - also make sure your intake boot is well secured - let us know, if its ok then I'll move the topic to a new Thumper kv topic titled engine transmission - Got Thump?

OK, I put in the correct amount of fluid, but the Blast still jerks at steady throttle, it feels like something is binding up, like if it had a worn chain, I thought that the belt was running up on the pulley but it probably isn't. Has any body else had this problem? Any place else to look? Thanks | ||

http://www.badweatherbikers.com/buell/messages/4062/34463.html?1060878648 This covers your problem from what I understand you are saying - see the above topic - but first I would go to my manual and do a clutch adjustment and see if that takes care of it.

Ok, heres the up date! The big kid brings the Blast home tonight and leaves it in front of the door. So I drive it back out to the garage and notice that after I get it started and let the clutch out the engine stalls, it was in neutral. So I again find nuetral start it and now notice that the neutral light is flickering and goes out on its own! So looking at the post you just showed the oprimary cover comes off ASAP for a little looksee for backed off screws and detent springs. I wonder if parts have been going through the primary chain making things tight? I will post as soon as the cover comes off on Friday. Thanks!! | ||

Swampy- Chase the Neutral Switch circuit first. Nothing you post leads me to believe anything is wrong mechanically. The bike is made to not run with the clutch out, kickstand down, and engine NOT in neutral. If the Neutral switch isn't working, the ignition system has no way of knowing that the bike isn't in Neutral. Make sense? -Saro | ||
| Reepicheep |
Swampy... was that with the side stand down and clutch out? If the neutral switch is not reporting "neutral" and the side stand is down and the clutch is out, the engine will not run. Like Saro says, chase the neutral circuit first. On my Cyclone, there is a metal post sticking out the shift drum that rotates around to trigger the neutral switch (mounted over by the main drive pulley). Hard to imagine that post being messed up, easy to imagine the switch or wiring having a problem. | ||

The neutral light part was not mentioned before - I concur http://www.badweatherbikers.com/buell/messages/20164/29935.html you should find info on the neutral switch here - GT - JBOTDS! EZ  edited by ezblast on August 20, 2003 | ||

Wheeee!! Here goes! The neutral light was flickering and going out and the gear shifter seemed to rattle into gear. Now for the good news! I pulled the peg frame off for the fifth time and pulled the primary cover for a little looksee. I found the bolt that holds the shifter pawl detent loose behind the clutch drum! The bolt also holds the shift drum in place, hence the flickering neutral light! Off comes the primary chain set, out comes the locktite and it now shifts like a dream! and all the transmission noise is gone to boot. Neutral is easy to find. I'm happy the Blast is happy and I can't wait to do it again on my other sons Blast!  | ||

Exactly what happened to my bike earlier this spring. What year is the bike? Jerry | ||
| Swampy |
A 2001 with about 3000 miles on it. Did you fix it yourself? None of the dealers I talked to said they have seen any "pattern failures" except the stalling problem. | ||
| Ezblast |
Lol - that pattern stalling comes from them adjusting the primary chain too tight - following the manual's instructions which are incorrect in that reguard. Also some helpfull tips on the Primary cover torque specks and what happens if your too tight on the tightening - http://www.badweatherbikers.com/buell/messages/4062/36332.html?1063487986 Got Thump?!

Loli's friend's Blast - an 01 - also had that screw loose. -Saro | ||
| Blastin |
My bike is also a 2001. I ran out of time and had my dealer (Hal's) take care of it for me. They found it as soon as they pulled the primary cover. | ||
| Darthane |
Hmm...you know, I don't have any problems, per se, but my Blast is a 2001 as well...it doesn't shift all that smooth and neutral can be a real bear to find. Having read this I think I'll go out there sometime this week and open it up just to make sure every thing is still hunky dorey in there. It's my g/f's bike now and I'd rather it not fail on her when she's out riding by herself sometime! | ||
| Swampy |
OK Darthane, what's this answer? Did you crack the primary and Solve the mystery of the transmission universe? | ||
| Ezblast |
LOL - my red bikes been checked, so I'm knocking on wood, but I just pulled the Black out to do a little run involving 35,9, & 1 and I shifted into 1st. got click and nothing, though the light shows I shifted out of neutral. Tried 2nd and the same thing. Looks like I'll be getting to the detent plate thing myself - lol - any hints on parts besides primary gasket - I may want to pick up since I'll be in there? Also the parts I'll probably have to replace are cheep? - lol - I'll be taking my time with this one. Damn! I was really looking forward to that ride! Guess today is chore & errand day with the Red, and tomorrow is disassembly and asessment day - sigh - any tips would be greatly appreciated! Got Thump?! Just Blasting on the Dark side!

You may want to replace the seal on the shifter shaft. If you are shifting and it does nothing I don't think it is the shift detent. What happens when you hold the shifter down inplace, does the transmission engage? If it still doesn't engauge when holding it down I would think it would be more than the detent clip. Inquiring minds want to know, but there is too many mosquitos to do any work outside till fall. Good luck, EZ | ||
| Ezblast |
Is the seal the brass collar in the cover? - I'd hold the clutch in, shift, hear the usual click, release and nothing, N light goes out but no engagement. Have primary cover off picking up tools tommorow to pull /basket/chain/sprocket assembly off and have a better look - any idea on things I should be looking for that would be wrong? GT - JBOTDS!

Do you have a belt? I had that happen to me once. The belt was lying on the ground next to my Blast! I know that's really obvious, but I just had to give you a ribbing! Once you figure it out, post pictures for the rest of us! | ||
| Ezblast |
LOL - It was the belt! Still have to replace the seal, gasket, and readjust everything, and wait for the belt to come in! While I'm in there I was wondering - anything I should look at? Looks ok to me, but still you never know! Spent an hour cleaning off the old gasket in prep, pulled the old seal - will probably button her up today or tommorrow, put the shoe back on already - slight wear - lol - she's ready to button back up just wanting to make sure I don't screw it up - lol - everythings clean and shiney;0) GT - JBOTDS! EZ | ||
| Swampy |
EZ, how many miles did you get out of the belt? | ||
| Ezblast |
12,000 plus all together naked miles - took that plastic off fist month - lol - so I inspect the belt pretty regularly and never even thought anything could be wrong - suprise! - lol - new belt picked up this evening - ;0) - now for a new tank cover and perhaps a couple of fairings - something - ultra light and durable - saw it on a dark Duc the other day - very nice! GT - JBOTDS! EZ | ||
| Ezblast |
Well - she's all buttoned up and running. The crossroads rear sets made putting on a new belt a breeze! Did a little adjusting, and I'll do some laps of GG park at different times tomorrow, and re-torque the cover 1 last time, and I'm done! The acid test is tonight - while I'm sleeping it will have time to leak - lol - so we'll see, however, I'm confident that it will be ok! GT - JBOTDS! EZ | ||

Man, shows you how often I check the Thumper Forums...I never did get the dang thing open. This whole Japan deal got in the way! Plus, I don't have a Blast manual, so I'm a little leery of getting that involved in it. I d/led the PDF one that EZ hosts, so now I can print off the relavent sections, at least. I come home tomorrow, though...I've got a ton of stuf to do to get the bikes back up and running. First will be the Blast, needs the primary adjusted and the fluids changed (if the primary adjustment doesn't 'fix' the trans sloppiness, then I'll open it up after I get the Firebolt running again). The 'bolt gets a new set of clothes, the fork oil replaced, fluids, primary, new belt, new tires, etc. etc. ...let's not even go into the truck now. Just to be sure, the primary adjustment on the Blast is done with the engine cold, yes? |
