I have had my raptir for a few months now and recently it started acting up. When it's cold the clutch kicks in late which means I'm trying it and it takes a while to get moving. When it's warm tho it works nicely. What can this be?
Please help

 

What type and weight oil are you using? Usually I have seen the opposite where the plates are grabby when cold. A smoked clutch will slip more as power is applied. If I were to take a guess, wondering if you are using a regular car oil like a 0 or 5w40?

 

I use 10W-40 Lucas engine oil for wet clutches. I have been using it for a while now about 3 weeks or so. The engine also sputters when I pull a wheelie otherwise it runs great and revs up fast but as soon as the front wheels leave the ground it starts to sputter. This isn't making sense to me what can cause that?

 

Hmm. I have never had this problem before myself. At first I was just going to say the chain is loose, but when it warms up it runs fine..... I guess it wouldn't hurt to check the chain just in case but that wouldn't have anything to do with the wheelie problem. Sorry I couldn't help much, hope you can figure it out.
