Dude do the work yourself and save some coin,I just last week grenaded my piston on my 86 rippin throgh a mud hole,Im not exaggerating when I say grenaded. The top portion from just below the rings was still in the cylinder,the rest was resting on top of my crank, the piston pin was the only thing left attached to the rod, I yanked the engine,split the cases,cleaned everything,installed a new slug,my cylinder had a few dings on the edges that were easily fixed and shes runnin as good as ever,I can't f**kin beleive the compression that comes with a new slug,makes every 500 banger I have ever ridden seem worn out,won't be firing her up with my DC's anymore for sure,anyways if you got any brains at all don't send your s**t to someone when you could do the same work yourself and save the labour coin for other bits your bike may need
