My boot on the drive shaft came off this weekend. When I tried to put it back on it appeared to be about 2" too large. Any explanations????

Also when the boot cam off, there was oil in the boot. Is this normal???

Thanks for your help.

Busglinger, I did not get transmission fluid on the rubber unless that was what was inside the boot when it slipped off. As to know why or how it came off, I have not a clue. The rubber did not crack or bust. I did pressure wash the motor just before riding it the last time.

Since you mentioned the transmission fluid, if the boot is not suppose to have oil inside, then probably the transmission seal has gone bad and cause fluid to leak into the boot and that is how it got oil inside the boot. And possibly it is transmission fluid.

Thanks for your help.

Please, anyone else have any ideas, please advise.

Is there no one else that knows anything about this issues that can help me????????????????

there is no tranny fluid in the bike, just atv motor oil .... what you saw in the boot was old grease that was packed in there ... the same grease for the front/rear axle shafts ... you can probably get a "split" boot to put back on to avoid dismantling the drive-shaft ... whatever route you go, it needs to be sealed

      2005 Bruin 350cc Oil pumping into airbox
      By BruceG
      Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

      Help with 1987 Yamaha Big Bear YFM350FWT Carb
      By ResQ91
      Hi Guys!

      New member and could really use your advice. I would have to believe this has been an issue for others but a search here came up with nothing......? (Probably me not doing search correctly)
       
      I have an 87 Big Bear 350 YFM350FWT
      The OEM Mikuni BTM carb is shot and would rather replace than rebuild.
      It is no longer made and I have had good luck with NICHE carbs so I ordered a #K-CRB-0006 This was what they said was replacement when ordered. This Carb only uses 1 Throttle cable. The Slide is linked so it uses one. (OEM had 2nd cable coming through top to move slide)
       
      Problem is when I ordered a replacement Cable from NICHE (#C-CBL-0061) the Cable wire is a little short, not allowing Throttle to return all the way down to Idle position. I called NICHE and they are at a loss. Haven't gotten back to me after 2+ weeks.
       
      What would you recommend other than a carb rebuild?
      Can I just use 1 of the OEM cables (It is the right length) and snip/disconnect the other that went to top of Carb for Slide?
      Or ??
       
      Thanks in advance for any advice you have!!

      2002 Quadrunner 250- Knackered cam and journal/"bearings", difference between 2001-2002 part and 2000 and earlier
      By kiriyaaoi
      Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves.  From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
       
      1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match.  I have no idea what this would cost.
      2. Buy a replacement head+cam+valve cover.
       
      #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option.  However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number,  11100-19B10, instead of  11100-19B01 like for all earlier models.  What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years.  Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical.  Would those work as well possibly?  I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on.  Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
       
      Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.
