Engine compatibility Question

[CHRISSER]

I have an 81h that just developed a serious internal problem. coupled with some very exsesive wear.

Since I also found an engine for a 79sf I have decided to go with it in hopes it will work on my bike.

Does anybody know of any problems I might encounter?

The new engine has both its coils and cdi box which seem to be in pretty good shape. Will I need to use those or can I stick with the ones already on the bike?

Watch out for carb jest sizes... and thats bout it. Oh, I dont know bout the yics stuff... but you can keep all electrics anyway... pick ups and stuff... IMHO.

To play it safe swap all the stuff that goes with the bike onto the motor cause the 79 coils are diff. from 81 . Just to be safe.

Re: Engine compatibility Question

You will probably want to use the 81's pick-up coil in the 79's engine and use the 81's brain box as well. I did something similar. I put an 80sg engine into an 81h bike. There was one wire that I could never figure out and it nevr was a problem. If you run into the problem, i will try to figure out what color it was. It was near the right side cover.
