bad engine vibration ?

<< < (2/2)

BDI:
How did they balance the crank? :?

n2682:
i beleave they shaved weight off of it least thats how he did my snowmobile motor im goign to contract the guy monday to see what all he did i droped it off and picked it up after hours so its a one man machine shop and i have an account i left him a note told him what i wanted and he did it?

n2682:
the internals in the motor are:
 
PRO X PISTON

 HOT RODS ROD

 AND STOCK CRANK

 

n2682:
 the engine builder said he shaved a lil bite off the left side crank half and he didnt do anthing with the rod and the piston because id be changing the piston out from time to time  he said he got the run out as close as possible so im just going to take the motor back apart and see whats going on ill post pictures on here when i get it apart. im still learning everyday more and more bout how to make a 2 stroke run perfect. some people say that u should weld the crank halfs is this only on two or three cylinder engines is it a good idea or a bad idea i can see clearly how u wouldnt wanna do this via changing a rod and so forth do u weld these cranks stewart you seem to be the man on here when it comes to makin the kx run its best ?

stewart:
i do not weld the crank pin  on the k 5..let me know when its apart the out off round and clocking specs of your crank
