....that is the question. Sooooo I found a huge nasty crack in my engine case wrapping its way slighly around the left side motor mount (just above the stator cover). It's spewing coolant. Awesome. I had a huge chunk of aluminum welded to cover a huge part of the crack, but it's going to need to be JB Welded or fixed using some other similar substance.
Anyone found anything that works better than JB Weld?

 

JB weld is the best thing Ive found.

 

i dont think anything's out that compares to JB weld

 

My girls bike has that same exact crack.

It's been jb welded for a month and a few wrecks later and it's still hanging in there with no leaks.

 

i always use quicksteel...

works way better than jb weld

 

do it! ed-o jb'd a crack just like that on his 6r and it STILL holding from last summer!

 

Nice.

I would like to add that crack snakes around the back side for another 3 inches....

 

did you have the whole crack welded ?

the regular jb weld is tough as nails but the jb quick ,eh not so much

 

We just went ahead and got another motor to swap in when this one finally cracks all the way.

Lesson learned.. remember to replace your spacers

 

that stuff works good also

 

my buddy welded, then jb welded his 929 in almost the same place. He got a trouble free 30,000 miles after!! I would give it a shot.

 

so the f4i's arent so bulletproof after all huh

its ok my f4i was alot worse, but thats what happens when it falls off the back of a truck doing around 80

 

i am pretty sure your stories are simular to how you both got those cracks

 

lets be honest here that is a common thing on f4i's

 

hey when you come up, have atl freestlye hit me up for my stock pipe... cuz i dont know if you read that other thread but he said his looks like **** and mine is pretty mint so you can just have that one if you want

what? the flipping down the highway part or the cracking around the engine case

 

thanks for the pipe and yes the flipping down the highway thing

 

lol........

 

well i got a 636 now so hopefully i wont have that problem again, maybe thats what twite needs to do to fix his problem

 

Jb Weld Will Fix A Crack, It Works Best If You Can Sandblast The Area And Leave It Rough.
