rebuild
i have done a few and have not found them to hard . all of the wireing does not have to come out . all of the steering does not have to be removed. i should take 8-10 hour,s and it,s back runing if you have all the part,s. new gasket,s , rod bolt,s oil filter oil ,ring,s, anti freeze. but you should have two guy,s to lift out and replace the moter. and maybe some valve shim,s if it,s a high milage moter. the hard part is lifting it out and putting it back. the rest is all nut,s and bolt,s and the only tool that i had to buy was a degree tool for the rod bolt,s . cost was under 20.00 cdn . the electrical was only two canon plug,s . one to the cdi and one to the voltage reg. and the oil tank stay,s right were he lives. the shop manual is a must for the spec,s etc,etc .
