Question JB Weld on mounts

Hello,

I have my 70cc motor mounted on a mountain bike. The bottom frame was too thick to use the stock motor mount, I had to use the long bolt and plate that came with Dax kit. It worked good, but I ended up losing one of the bolts that attach the plate to the original mount point (I replaced original long studs with bolts) even with lock tite after about an hour long ride.

My questions is, has anybody tried JB Weld to secure their mounts. I was thinking of just cold welding the plate to the original mount point.

Thanks in advance,
Roman

If I am hearing you correctly - it does not sound like a good idea.

Maybe this will help. Sorry i am at work at the moment, all I could do in a short amount of time



Just to fuse the plate to the bottom mount, and maybe put a bead on each bolt. (I heard you can use soldering gun to melt them off if needed later)

OH I gotcha - there must be a fundamental reason why Loctite didn't work. What type of Loctite? How old is it?

I don't see bonding those areas helping all that much but on the heads may help a bit.

I agree with Ghost. Loctite, and maybe some good lock washers........

I used locktite blue (med strength).

Thanks for your responses. I guess I will try again with locktite. And maybe use a better lock washer (was using regular spring lock washers).

Cheers

Default I have done at least 300 builds and ....

and thousands and thousands of miles. I have never ever had to use loctight. Ever.. If you need to use loc tight, you are doing something wrong. Loc Tight will void any warranty. Loc tight will ruin your engine. Never use loc tight on these little motors. Loc tight has its place in the world. But it has no place anywhere on these little motors. Enjoy the ride...

I dont really see how locktite will "ruin your engine"... It may seize the bolt in place, but thats hardly a ruined engine.

A lot of people on this forum seem to use it.
