This has already been covered but I'd like to emphisis .
CHECK YOUR NUTS AND BOLTS ALWAYS.
I wash my ride either before or after every ride.
Not just because I like a clean bike , but It forces me to look at every inch of my bike and catch any impending problems in the shop, instead of getting a surprise at 40 mph, when I'm surrounded by traffic.
I'm not sure if all the kits are the same but my 70cc came with aluminun nuts and bolts. These should be illegal. lol
I doubt I'm the first to find out how easy it is to strip a bolt.
I bought steel bolts cut off the heads and replaced all motor mount studs and exhaust studs with these. planning to do head bolts aswell as soon as 1 strips.
Steel bolt, applied lock tight aswell as a lockwasher, and to top it off, steel locknuts. over kill alot may say but they do not vibrate loose.
Total cost was $4 not including the locktight which was around another $5.
Head bolts are still stock but I,ve double nutted them using a locknut on top of the stock nut.
I still put a wrench to each and every one of them but they havent budged at all.
A loose nut or 2 might not sound like much to worry about until your engine shifts position causing the chain to jam on the small sprocket, locking your back wheel,sending you into a sideways drift directly into the path of a 4000 lb hunk of steel (car) thats hurtling down the road beside you at 60mph.
this is not what might happen, this is what WILL happen if your motormounts are neglected and loosen off.
PLEASE CHECK YOUR NUTS AND BOLTS ALWAYS
