I haven't been able to fully get all the power down on the quad. It's a semi-automatic, non-electric shift, TRX250. I can't find any information on this topic so I'm trying here. Whenever i'm in a high-ish gear and I give it some gas the engine RPMs go up but no power goes through the driveline. Eventually it will "grab" and the engine RPMs go down and I can clearly tell and feel that the engine and transmission are bound. But when ever I gas it, it slips. Happens a lot on hills, and is starting to happen just normally. I have a feeling the "Wight Clutches" are worn or something. The clutch that engages after the engine hits a certain RPM. I don't think its the main clutch pack for shifting gears, but I could be wrong. What is going on?? What can I do to get more power down? Is this common? Because it sure doesn't seem so.

Thanks everyone.

Yep, sounds like the centrifugal clutch is slipping, but it could be the change clutch so inspect those too once you've got the cover off. You may have to replace the drum along with the weights and springs, its probably grooved by now. You won't know for sure until its apart.

For now, try to readjust the change clutch to see if that improves anything. Also make sure that the motor oil you've been using is JASO MA or MA2 approved for wet clutches.

So just pull the front cover off and inspect? How big of a job is it to change that stuff out?

Is it reasonably easy to swap those components out without having to pull the motor? That's the big question.

Yeah, but do it the way that you're most comfortable. If I were doing that work I'd yank the motor and do all of the work on the bench. But thats just me... I'm a busted up n' bolted together old fart with a sore back 24/7, bad eyes and bad hands. I look for easiest on the body... and I gotta have lots of light to see with lots of extra space around the subject for my artificial eyeballs headset. I used to be a polar opposite... like a bull in a china shop. No mas tho... :)

The FSM will clue ya in on all that you'll need as far as tools and the procedures and whatnot.
