Engine Noise

[GrantG]

I have an 87 250x and i have replaced the cam, cam bearings, cam chain and cam chain tensioner and i still have quit a bit of noise coming fom the engine. Any ideas what it could be?

check you valve clearances they may have worn seats also if its an aftermarket cam you might get more noise....

The clearences are good, but ya its a stage 1 hot cam so maybe thats why.
