really feeling stupid, didn't take off the valve adjusting cover and see 2 hidden bolts before whacking it loose with a mallet.

a piece snapped off IS IT ALUMINUM? WELDABLE? It looks to be aluminum!

Would jb weld hold?

 

I've never had any luck with JB weld as a bonder. It's more of a metal filler in my opinion. You'd get down the trail and snap! It sounds like you might just have to bite the bullet and buy a new part.

 

Buy a new one you'll be better off in the long run

 

Ds, Just get new one or call trinity and maybe they can get you one.

 

Midwest Action Cycle sells Yamaha stuff now...they were the cheapest I could find on Honda parts...the #is 1-262-249-0600

 

not getting a new one, gotta buy the HEAD and rocker cover together. I cannot see the rocker cover leaking really since there is not alot of oil in there and the crack will be on the rear (toward the carbs) which is tiltled in the air and oil should drain away from. After sending my motor to trinity I cannot afford a new head and rocker cover! haha going to try getting it welded tomorrow...

Is it aluminum?


will post results of trinity's service and work

 

My friend has a lakota and busted the case twice by the front sproket, first time he bought a new cover $60, second time he just got it welded at a shop for like $10, its held up so far... and it is aluminum.

 

Engine cases are made of a very low grade aluminum (pot metal). It can be welded but only by someone who is experienced at welding that type of metal. It can easily be burned up by an unskilled welder leaving you far worse off than you are. JB weld is pretty good for bonding, however it makes good sense to rough up the surface aroud the cracks. JB weld adheres better to a rough surface. Also if it is spread out around the crack it will be stonger and will be holding the cracked piece in place rather than bonding it. Unless you can find a welder that is experienced at welding pot metal you are better off using JB weld. Rough up the metal surfaces with coarse sandpaper or even a file and clean it off with contact cleaner first. Good luck.

 

Just my $.02 worth. Have it welded by a reputable shop. I have tried various mends like JB, etc. Sometimes they hold for a while if it is on something that does not heat up and then cool down. But in the long run it will not hold very well.

 

when i got a hole knocked in my case by my counter balancer we used jb weld. what we did was first rough up the dges. the we made a piece of alumium with holes in it and with screws or something i can't remember our exact proceddure. then we covered it in jb weld.then sanded it down on the outside and it is good as new.
