Roketa 250cc !!!NEED TORQUE SPECS!!!
Does anybody know the torque specs/pattern for the roketa 250cc single cylinder engines? it's on a Utility ATV. It lost all compression and I think the valve may be stuck open but I don't want to take off the cylinder head without being able to properly put it back on. Any and all help will be appreciated, I've been looking for an hour and can't find it, I'm either stupid or there really isn't any info on these out there...
the atv is just like this:

No **** shirlock. but if they are oily it's going to cause less resistance tricking the tourqe wrench into thinking it's not at the right tourqe yet, making it overtourqe possibly stripping threads or breaking bolts. Correct?

don't know what the professionals do, but this shadetree uses lubricant on the bolts so as to avoid friction which fools the torque prematurely. i use an antiseize on the threads and the bolt head surface that'll take heat if around the engine. using lube will help the bolt to stretch, if dry, it will more than likely twist the bolt rather than stretch it.
if you have a manual, reference that.......but judging from the original post, you don't have a manual...........good luck

I got on the roketa website and tracked down my parts I need and everything but when I put in my ZIP code and all, I hit recalculate for the shipping and it remains $0.00?
and the other website, there's 2 different size exhaust valves, I don't know which one I need. and I can't find the valve retainer for the 250cc...
