883 to 1250 conversion kits

Tim, I not sure of what kit's are out there , but it goes from 883 to 1200 unless there making a new one to 1250 , someone put a like to a shop in Mi that does the 88 to 95/ 130 for the twin cams they might also do the sporty good luck & let us know about your project

havent done any of them but Ref Perf gets good reviews on a couple of other sites.

Im curious as to how they get past 1200 without boring, you either increase cyl bore or stroke, in that you're not splitting the cases you are not stroking it so bore increase is the only deal.

Just curious, post a link to the kits if you can.

im curious also....wonder if they moved the wristpin and shortened the piston??

Tim thank's for the link's , I read both & both seem good the rev had the kit for the 883 , I going to check into it for my Daughters bike she want's it faster , but I'am also looking for dependabilty over time , I don't want to have to keep working on A engine after or before every ride or two :gah:

tim, thanks for the links........

You need to clean up that avitar, It's hurting my eyes :gah:


That's good seems they figured out how to get a little more out, I'd say either kit is good, the rev performance people have been around a while I believe you can chat with them on vtwinforums.com they may be a sponse.
