RyanB58 Posted December 19, 2005 Ummmm, I had one on my 2002 YZ and the thing was wicked. But it still was not up to snuff with a 250F so I made the switch. It was really fast and for a 125 had considerable amounts of low end, but when it came to it the 250F was a much more foregiving bike. Never had any problems with it, but I believe that in competition in AMA no overbore is allowed. You might check on that if you compete in AMA races. Share this post Link to post Share on other sites

shift1313 My Rides (4) Posted December 19, 2005 are you having someone install the kit for you or are you going to tackle it yourself? If i remember correctly you need to do a good little bit of port work once the cylinder is bored out and replated. There are no problems at all with going up and it will help your lowend out a bit but just make sure your machine work is done right. Share this post Link to post Share on other sites

RyanB58 Posted December 19, 2005 I had RPM do mine when he was doing two-strokes still. It was the most professional work I had ever seen. I shipped it on Monday and had it back on Friday, very good work. I know he has someone in Michigan doing his work on two strokes now. Share this post Link to post Share on other sites
