CB750 DOHC Engine rebuild help

[funkja]

took the bike to a local shop for some tune-up, checked the compression and he said 3cyl's are runnin in the 30's and the other is in the 80's (whatever that means, i'm not a mechanic. i assume low is bad).

he recommended rebuilding the top.

what would i need for a topend rebuild? pistons/rings/gasket/maybe head studs while he's in there?

any good kits out there?

thats real good to know! i did ride it to the shop, and it does ride extremely sluggish (compared to my buds 750)
i think he's tryin to get what he can out of me because i ride it daily and havent had any problems, i took it in to have the carbs sync'd and he did the comp test.


i agree this engine is somewhat heavy, had it out already workin on the frame. took a try or 3 to clean in up high enough to get it on the shop bench however, its nothin compared to slingin 90lb wet alfalfa bales for 12 hours though

thanks for the advice,
maybe i'll take it elsewhere!

anyone know a GOOD inexpensive mechanic in the Des Moines, Iowa area?!

I would redo the comp test and try some oil in the cylinders

Totally left field but did you ever rebuild? If so, how do you remove the jugs?
