Hi there. New here... Had a crazy idea...will the 100mm jug fit on the 610 bottom end? A carbed DOHC 630?.. D
and timing chain along with the tensioner.. you are just getting started... I'd check the price on the 630 head before you dream anymore and put it to rest. Not trying to be mean but you will see what I mean when you check that price.
LRPct, please clarify your comment; "It really doesn't seem to have more power." Are you talking stock vs stock or modded in an equivalent fashion? I agree there is a lot involved to convert a 610 carbed top end to a 630 EFI one. You'd be better off buying a new or used 630. It's not worth the cost involved in my opinion.
Interested as well. Seems that it may also improve the rapid cam chain wear issues because of the new style cam chain tensioner.
