I was fine at the beginning but now I have been losing bolts also. Just lost all 3 bolts in one of my muffler to pipe. Not sure what the big 4 knows about the whole bolt thread thing that the Chines don't know.

They know that lock nuts cost many many times more than regular bolts. One would think they would apply some thread locker to the bolts to spend less than the lock nuts, but unfortunately the mold release compounds they use to make the nuts would have to be washed off to allow the threadlocker to go on, which would create rusting problems before the ATV even made it to the USA! It's a tough situation to deal with, that is without spending much more money on manufacturing. Given the ultra cheap cost of chinesse labor, one would assume the cheapest manor to do it would be to hire people to wash the bolts after they arrive at the assembly factory, then dump them into a shaker that would help dry the nuts, and then dunk them in 99% anhydrous alcohol to rinse off any water that remained. Then each bolt would have to have loctite applied (there is a machine that could do it cheaper than even chinesse labor could pull off.) Also, I could be completely off base on this. If they are using galvanized or stainless hardware, there may not actually be any mold release compound. If the bolts are painted, then there may not be any compound. I just don't know. If you take out a bolt where there should not be any oil or grease or anything... does it feel greasy? That would be the clue. I should have my jetmotos in 6 days or so and I will see for myself!

I believe the problem is that they would have to go to stainless steel or graded (grade 5/8) for all the nuts if they didn't want them to rust after removing the oil. If you want your loctite to hold on bolts, you need to hit it with some good quality alcohol. I use MG Chemicals 99.953% anhydrous alchohol Then apply the loctite (liquid is better than foam or gels) and let it COMPLETELY DRY before assembly. This both keeps the loctite out of anywhere you wouldn't want it (bearings and the like) as well as providing a better hold. Also, do not use loctite on the entire thread or you may not be able to install it fully. If you use a decent line of liquid down the length of a thread, (apply from underneath, not to the top of the bolt) then it will hold great as well as not binding when you install the bolt. I'm super **** about this kinda stuff, and none of it may be needed in this application, but this method has always worked very well for me! =)

Alcohol is not dangerous if you don't use around an open flame or on a hot motor. Just put a little on the rag and wipe the bolt clean. It's not any more dangerous simply because it's 99+% pure. It just doesn't have any water in it which will cause rust on the bolt.

JetmotoUSA.com's quads are built in China. All Jetmoto quads (currently) are built in China.

Man they must of used up ALL the thread locker up on my 250. Several of the control arm bolts I like to NEVER got them to loosen up. Only real problem I've had is with the two jam nuts that hold the sprocket hub in place. I've retightened them a couple of times using blue removable Locktite, might use the red Locktite next time.

I've used acetone to degrease parts before where I worked. I've found carb cleaner works too.

BTW, the bolts and nuts appear to have a parkerized finish. Green colored coating.

Yeah, acetone and carb cleaner, or any presurized butane/isopropane/isopropyl alcohol spray will work fine. I use pure alcohol because I bought a gallon of it for $20 forever ago and it just never runs out. Carb cleaner is cheap too. Have you tried letting the loctite dry before putting the nuts on the bolt? Have you tried using a washer with a loc washer as well as the jam nuts and loctite?

For anyone reading this, red loctite is NOT permanent, but you have to heat it to remove it safely with tools. Blue is removable with hand tools without heating. green can be used on parts that are already assembled, but where the thread is showing somewhere. Also, only use loctite on metal to metal because when it dries, it turns to plastic. Putting loctite on a metal screw and screwing into plastic can form a permanent bond.

Loctite will also do evil things to aluminum.
