lms1977 Posted July 24, 2011 Report Posted July 24, 2011 As far as the bore only go as big as you have to. Timing plate or mod tours would be a good idea. If you have the money you could get it ported. Sky is the limit. Quote

I AM NEW AND OPEN TO ALL ADVICE. stop with the caps....no one likes a yeller on here. After that......take your cylinders to a reputable powersports shop........tell them your doing a rebuild and you need them bored. They will meausure your cylinder bore and then machine them out to the NEXT appropiate size. you dont just go in and tell them you want it bored .040 over. They will order the next sized up pistons and then they will bore them to the exact tollerences that the pistons require. Also make sure sure that they know how to chamfer the ports to make sure your rings dont snag and rip shit up. Its WAY easier and cheaper to send them off to a site sponsor on here.......i always used Jeff at F.A.S.T. Racing........but i hear herr jugs racing is good also. Give one of them a call and have them do the work as you sound a little green at rebuilding bikes.... Quote
jlsparky7 Posted July 26, 2011 Report Posted July 26, 2011 Check out the link in my signature for a rebuild how to. Quote
Larry's Shee Posted July 26, 2011 Report Posted July 26, 2011 Welcome to BHQ !! Why do you think you need a rebuild? Low compression? Quote
FASTOYS Posted July 26, 2011 Report Posted July 26, 2011 I recommend only boring to what size it takes to clean up the cyls.. then add cool head, timing plate, and reeds if you can afford it. Give us or any of the site sponsors a call as we can help ! Quote
