julien_d said:Yeah, that's the way I do it also. I meant one side as in the left clip, then the right clip just gave me a fit for some reason. I have not had that problem on my KDX. The KTM is just a problem bike :coocoo:
How does he replace the piston pin circlips without taking the cylinder off of the piston??whenfoxforks-ruled said:If you enjoy being thrifty when pulling the top end, and do not want to replace the rings, leave the piston in the bore.

You're kidding right? Are you serious or just giving us a wind up?dave89b said:well....after 3 gallons of fuel. something happend. it kind of sounded like a circlip came out...................now its seized. now i get to take it apart again......
dave89b said:after riding around for about an hour today only using 1st and 2nd trying to break it in. i let it sit there idling for like an hour and was idling perfecct . then i went around some more and after about 10 minutes of puttinng around i gave it a little bit throttle in 3rd before i put it away and as i was slowly coming back in 1st gear then it happened. 20 feet from shop door
but seriously, i've been an outboard mechanic for years and have re-used cir-clips plenty of times. and those engines are STILL running great.
Wrong! Re-using the rings once removed, is just as bad as re-using the cir clips. They will NEVER EXACTLY line up again, NEVER. They will prematurely wear out. I just recalled on some other forum, where a boat mechanic discovered that we are stupid for running expensive 2 stroke dirt bike premix oils. Boat engines run a lot hotter, he "figures", so marine premix oil is a lot better, he had never had a problem, so he "figures". WRONG, I am not retelling my "figuring", or at least I am doing my best in a sea of ignorance. Damn near every Micky mouse plan you can think of, myself or others HAVE already tried, with failures. So why perpetuate ignorance? There is solid data available to prove it, so why argue it? Back to the used cir clips poster, Dave89b, you can send your top end to a reputable shop, and have the top end fixed, for about what a used, questionable condition top end will cost. Cost per hours of fun, against cost per hour of fixing it? A good KDX top end should last a really longtime! People do leave the piston in the bore, and remove the cir clips, so as to not replace the rings. Not a lot of fun, till you have done it a couple of times, go figure?

I wouldn't be overly concerned with re-using the same rings; they're located by pins in the ring lands and will go right back in the same place. If there are "grooves" in the bore large enough to have an effect on ring seal, the cylinder should be honed and new rings installed before he buttons everything up.
The rings float (constrained by the pin) anyway, right? So they don't really "line up" with anything besides the pins that keep them from lining up with each other. I'd say even on the pin, compressed in the cylinder, they have a good 1/8th inch of rotation play.
