I changed the transmission fluid in my Buell Blast and when I went to take the bike out for a ride about a block down the street the clutch lever handle became extremely loose and I couldn't shift into first gear. I was actually having trouble shifting at all. I wasn't too far from home, so I managed to make it in the gear I was in. So, I just tightened the cable from the adjuster and that seemed to fix that issue. I just got back from riding, pulled into the driveway and the gear shift lever drops extremely low. I have to get at an extreme angle just to get my foot in there to pop it back up. It still doesn't fix the problem. The gear shift lever is extremely low and I can't get the bike into neutral. I didn't have any problem before getting it into neutral. Does anyone have any idea what's going on here? | ||

For what it's worth, I put in Royal Purple 70w90 trans fluid. | ||

I really doubt that it was (the problems, plural, you describe) because of the oil change. It almost sounds like 2 problems. I'm not knowledgeable on the blasts. I had shift problems on my M2 because a little clip broke off and shifting was really weird to say the least. So does the clutch lever seem OK now and it is the shift lever problem now? Also I just use 15w-40 motor oil in the tranny/primary which is the same as what I use in the engine and never had a problem. Does the Blast actually tell you to use 80/90 gear lube? I do use it in my Jeep axles and 5 speed manual tranny but not in my Buell (Message edited by Buell_Bert on March 18, 2011) | ||

I read between a few forums people talking about using 20w50 in their transmission or 70w90 for their Blasts. I don't know if one is better than the other? The clutch lever seems fine. The gear shift lever is messed up. Rather than it being above the foot peg, it's quite far below. I wouldn't be able to ride with it being that low. I really don't know how it happened. Could I have accidently knocked something out of place? I'm just confused. | ||

Is this possibly as simple as the gear shift lever itself moved? ... and all I have to do is unscrew the gear shift lever, move it up, and tighten it? | ||

That is always a possibility - Kilroy | ||

Not positive about the blast, but I think it is the same as all the other XB's... There is a specific sequence in the manual reassembling the clutch cover and ball and ramp mechanism. It doesn't sound like you followed it, and what you describe is about what I would expect. Get the service manual and go by the book. The difference in lube weights isn't really a difference in weights... gear oil uses a different scale than engine oil does. So the two different weights you are quoting are actually very close, the gear oil just has extra things in it that make it a much better gear oil, but that you DON'T ever want in a combustion chamber. Either fluid should work and shift fine in your blast. | ||

I didn't think I really had to when changing the transmission fluid. I have the service book, but it didn't say anything about reassembling the clutch cover in the section of replacing transmission fluid. I imagine that's in the book somewhere, but wasn't included with the part I was originally going through. So, you're saying I have to pull cover off again and make a few adjustments? Same place I added the transmission fluid? | ||

It's the little derby cover thing that has the ball and ramp assembly... so if you pulled that, you have to follow the instructions to put it back. If you filled it up via the inspection plate (smaller cover with two screws, if the blast even has one) then it all would have stayed the same. it's not a big deal, and if you find the S1 manual here on this site it will be about the same procedure. Blast owners, feel free to chime in here so I don't project my experience with tubers and XB's inappropriately and confuse somebody... | ||

Is that for the clutch or gear lever? I thought that was for the clutch? | ||

By the way, I meant 75w90, not 70w90. | ||

The difference between gear oil and engine oil is quite a difference. It is the weight. Try running a bike tranny at 80/90 as opposed to 15/40 when it is below freezing or below zero. I used to have a 69 GTX (Hemi 4 spd)and running the 80/90 gear lube below freezing I would park it in 2nd gear because I could get to school faster. When it was that cold I could not even shift it then. The new lubricants we have now are unbelievable. But you still have to look at the proper weight lubricant for your individual equipment use. Any oil is better than no oil. | ||

For the clutch lever, which is attached to a cable, which is attached to a ball and ramp mechanism, which pushes the clutch plates apart. If you took off that derby cover,then you should re-do the adjustment procedure putting it back together. You shouldn't have had to mess with the gear shift lever. |
