Rrage523 Posted March 26, 2010 So I just rebuilt the top end of my 02 yz250f and just finished breaking it in per manual and it seems like its running really good and not smoking at all but doesn't seem to be as snappy as it used to be. It seems like it hesitates ever so slightly. Is this common with rebuilds, maybe the rings are fully seated or maybe my throttle is a little out of wack and I just need to adjust it. What do you guys think? Share this post Link to post Share on other sites
yz250fnewbie Posted March 26, 2010 not sure what ancillary issues you may have (not directly related to the top-end) but after i did one on my 03 it ripped like it hadn't ripped for awhile. ran strong and hard. it was my first top-end and i was really surprised how much performance i had lost and gotten used to. made a big difference.
