Not long ago I bought a pair of Andrews racing cams #10 grind for my 78 650. Does anyone know if I will need new/different valve springs to run these cams?:S

I had been kind of scared to put these cams in myself, but in my spare time I have looked the bike and the cams over. Looks like there may not be much to it. Does anyone know the torque specs on the cam journals?

Yeah, you'll wanna rejet for the cams, if you want all the power available from installing them ;) Can't help you on the exhaust recommendations though :unsure:

Use red loctite on the threads. Make sure you clean the bolts and the cam bolt holes with brake clean and blow them out.

Pick up a bottle of LL5 lifter lube at your local NAPA store and lube the cams and buckets well with it. I always follow break in procedures even with used cams.

The torque for the sprocket to the cams is 11 ft./lbs.

The torque for the cam shaft caps is 104 in./lbs. (or roughly 9 ft./lbs)
