Hi, just bought a 2001 Blast... its yellow... not exactly my color of choice but the more I ride the more it grows on me. Anyways It happens a lot when I down shift in to second and first. I get this clanking noise... don't know what it is... | ||

Welcome to the board Azblast! How many miles are on your Blast? As they get more miles on them they begin to shift better, usually around 5000. There are a bunch of threads in the knowledge vault here on what I am going to tell you. So in a nutshell: Change trans fluid to a 20W-50 synthetic engine oil. Adjust your primary looser than what the maintenance manual suggests, than adjust your clutch. If after 5,000 miles its still doing it, remove the primary cover and adjust the shifter pawl clearance. | ||

Welcome AzBlast! I knew Swampy would step up with a good answer. There is also a shifter bolt that would come loose on the 2001 (& 2000?) models, but do all the other adjustments first. Some clunk/crunch is 'normal' into first and between 1st and 2nd, but it can be lessened or all but eliminated. I know Swampy alluded to the loose bolt with his " There are a bunch of threads" comment. | ||
| Swampy |
Gosh, I forgot all about that!....LOL! The shift drum retaining bolt.....if all else fails! | ||
| Azblast |
Thanks a lot for responding so quickly... it has like 3600 miles on it... I will do all that thanks. | ||

My (new to me) 03 Blast jurks in 1st gear like it's jumping a tooth. If I baby it, it's O K. Did I read about a bad (soft) not hardened correctly set of gears around that time? I'll probably later have to pull it apart & try to undercut the dogs. Any other options?---Thanks,,, De & how the heck do I start a new thread under "Transmissions" so I give the thread the proper title? Thanks again,,, De  | ||

Clutch adjustment at the primary. GT - JBOTDS! EZ  | ||
| Gearheaderiko |
Concur! Try that first. There hasn't been any gear problems that I've heard of. You also have to take the engine completely apart to do the tranny. Perhaps you already knew this, but it really bugs me. I want a trap door for the transmission! | ||

It is all CLUTCH and PRIMARY CHAIN adjustments ... In BLASTing LaFayette | ||

TWM: This is the thread you want. Too many threads and it just gets confusing and harder to find info. | ||
| Tyronewildman |
What? no trap door-guess I'll live with it-with the trap door on my '84 Sporty & my '02 S3T, I just figured the P3 would be the same. So on the thumper board, no new threads I guess. Not like the Old School Buell Board......Later,,, De | ||

"So on the thumper board, no new threads I guess" There are new threads allowed. However, if you've ever tried to find anything on the XB forum or asked a question there, you'll find it a daunting task to find info (because of the many threads) and you'll get no response to a question asked (because of the many threads). The Blast hasnt changed in 8 years and almost everything has already been covered here. Its a simple bike and I'm trying to keep the Thumper side simple and helpful. Let us know how the clutch and primary adjustments work out and if that solves your problem. Thanks. Just asking a question on the Thumper Forum opening page is usually good enough to get a response and moved to the appropriate thread. We (usually) dont chastise people for posting in the wrong thread or off topic. I will change the "Primary Drive" heading to Primary and Transmission. | ||

Gotsha, I guess. Still "Transmission clunking into gear" doesn't seem to be a good thread title to quiry about gears jumping out of gear, or gears jerking when under load, etc. but I'll live with this also. Does the clutch/primary chain adjustment (Above post) have anything to do with my problem, or is that the answer to the original question of clunking when going into gear? Gearheaderiko, you said "There are new threads allowed." Wow does this happen? Just wondering... You are correct that the Blast hasn't changed MUCH-ever squeezed the brake leaver on a 2000 model? With its stainless steel/teflon brake line it was just too good for the riders in our classes. In my 12 yrs as an MSF & 6 years as a Rider's Edge coach, I can tell you that the Blast has the best front brake of any training bike I've ridden. OOPs, getting off the subject but I've always liked the Blast & happy to be on board. Thanks for keeping the board simple...Later,,, De | ||

The answer that EZ, Buellistic and I all pertain to your question/problem. Make sure the primary chain and clutch is adjusted properly. This is generally the root of most Blast tranny problems. 2000-2001 had a shift drum retaining bolt that would come loose inside the primary, but you have a 2003 (doesnt mean that it couldnt happen, its just not usual). I've activated the "Start New Thread" at the top of this page. If you'd like to repost a complete description of your problem under a new thread title, go ahead! We would still like to know if proper clutch/primary adjustment solves your problem. New threads happen all the time, but redundancy is pointless. Take a look through the board and see how many threads are already the same question asked differently.  ? | ||

I agree with Erik on the new thread issue. I remember when I first came to Bad web I found it a bit confusing to figure out where to post about my "second clunk issue". There were probably three or four places it could have gone so in frustration I made the mistake of starting a new thread which just added to the problem. Just look at how big some of these topic lists have become and in many instances there are numerous duplications. I'd like to see some of them blended into other posts just to clean it up a little but I imagine cleaning up posts would be like trying to heard cats. These guys work pretty hard keeping the bad web (thumper) house neat and tidy. Thank You! whoever you are! | ||
| Gearheaderiko |
Thanks. I've done a lot of cleaning up and consolidating but as you know there's more work to be done. One thread at a time! EZ is the king of the Thumper side. Without his time and effort the thumper side would have been a complete mess. Also, if the information is here (or anywhere for that matter), he can find it! | ||

Transmission wont shift at all I have opened the primary where I have been many times before clutch stator rotor etc . The drum etc all look good any Ideas from the group would apreciated | ||
| Swampy |
Sorry to hear that. Did it happen all at once? Now I don't have the correct nomenclature for all this but you have the primary cover off right? The crank sprocket is turning the primary chain which is turning the clutch hub? Is the input shaft for the transmission turning? Now is the shifter arm moving the shifter drum? | ||
| Gearheaderiko |
Once you have the primary off, again, all Swampys questions are good. It could range from a slipping shifter arm to the transmission jammed at the gears. Maybe its just a loose bolt or bad spring but unfortunately, you'll have to take the primary apart to find out! | ||
| Sportymark |
Does the Blast run a detent plate liek an older tuber/sportster does? the clip that holds those on dies really easily, and it is behind the clutch hub so it is hard to see. | ||
| Swampy |
Yes they do, its kind of a flimsy arrangement but get the job done for the most part. With all the adjustments made properly they function well though. | ||
| Ezblast |
Yes and if you have a Tuber you can cross reference to the Blast manual to check for updated parts - the trap door being the only differences - per Terry P. GT - JBOTDS! EZ | ||

Hope this is an OK spot to ask my question. I searched, and can't figure out how to add a new post to archived threads (some of which may have been a better place to put my question). But it's late, and I have to shower before the better half gets home from work. I thought long and hard about this before I did it, but so far 2 out of 2 people told me I should not have done it. When I was changing the transmission fluid, I needed a new O ring for the magnetic plug and got a gasket for the inspection cover since I was making the trip anyhow. I had not yet taken the cover off, but since making the trip, and didn’t know what the previous owner did, decided to replace it. The HD dealer closest to me, and open on the Saturday I needed it, is not a Buell dealer, or service center. They had the O ring and gasket because they had them on hand for their Rider’s Edge course. The gasket I got was paper, cardboard, or what ever thin material they make it from. I provided the part number per the part’s catalog. When I got the cover off, it had a rubber gasket, at least what I interpret from the parts diagram to be the gasket. It’s a thicker, rubber gasket that actually is fitted into the cover (if that makes sense). So before putting the cover back on, I sat there wondering what I should do. The parts manual I have is for 2007 Blast. The diagram in the parts manual shows ONLY ONE gasket. It’s page 14 of 95 of the PDF. I wondered why I had 2 different gaskets: (1) the rubber one that fitted like a boot (I don’t know if that’s the correct use of the term boot); and (2) the paper one I got from the dealer. The manual only showing 1, I figured there shouldn’t be both; otherwise it would show it in the diagram. Right? I put both on. The reason I did is because the side of the rubber gasket that seated against the primary cover, had an imprinted groove that seemed to fit the shape of the paper gasket. I started to figure the previous owner might have left the additional gasket (paper) off (even though this is counter to the diagram. Another reason I put both on, was because I really don’t believe the paper gasket would have sealed anything by itself (without the rubber one fully making the meeting of the two parts flush). It was suggested that I should not have done that, but, since it’s not leaking, leave it until I have to change the fluids again (but check for leaking regularly). I wish I had taken a picture of it. Questions: 1. Does this sound familiar to anyone? 2. Should I take the time sooner, than later, to remove that extra gasket? 3. Is it possible that my year (2001) has different parts from the 2007? 4. How do I verify the year of my bike in case the previous owner told me the wrong one? (After all, the owner’s manual he gave me was for a 2002, though he pointed out it was not for the year of the bike). -------------------------------------------------- -------------------------------------------------- -------- See, http://www.badweatherbikers.com/buell/messages/201 64/17992.html. The gasket also changed from a countoured rubber "quad ring" as the manual calls it to a thin rubberized gasket with a metal reinforcement. Is this “rubberized gasket” what I am calling a “paper” gasket?” What year did this change? -------------------------------------------------- -------------------------------------------------- -------- | ||

1st: Perfect place to ask your question. 2nd: If it doesnt leak, dont worry about it.(and no, it doesnt use 2 gaskets). 3rd: The gasket and cover changed in 2003 (or between 2003 and 2005). The new gasket indicates the change was in 03. What was the new gasket part #? (Message edited by gearheaderiko on July 19, 2008) | ||
| Robi |
should have been 25377-03A. At least that's what I asked for. If the gasket changed between 03 and 05, and I was told the year of the bike I bought was 2001, would that suggest the year of the bike is wrong? Or that the inspection cover and/or gasket were replaced. It seems like the rubber one would be better than the rubberized thin one. Why the change? | ||
| Gearheaderiko |
The change probably happened because the rubberized one sealed better. The year of your bike is right and the later gasket and cover is recommended to be installed as an upgraded unit (others have much better knowledge of the change-thats just what I remember). Original clutch cover pt# 34772-00Y and gasket (o ring style)pt# 25351-00Y New cover 2003-up gasket pt# 25377-03A. Cover and gasket kit pt# 25349-03 (includes 25377-03) | ||

So far, I've never changed my rubber gasket. They didn't have one when I changed my fluid the first time, so I tried reusing it. After 34K, it still doesn't leak! | ||
| Gearheaderiko |
Never changed mine either! | ||

Does anyone have actual pictures of the transmisson gear set? I would very much like to see what the gear dogs look like in actuality...the service manual has no clear pictures...the breakdown drawing appears to be your typical approximation where the dogs look like snaggle teeth. The root question is, are the gear dogs run as cast, or straight parallel machined, or back cut? (one picture in the SM seems to show the dogs you can see as double back cut...I don't wanna disassemble my motor just to see what it looks like...I am going crazy to make mine shift like I want it too...I want to gain as much knowledge as possible BEFORE I take it apart...it will get some pretty serious mods when I finally do...but thats another thread  |
