Dec 9, 2010 · It's been a couple years so wanted to bump this thread. Larry is still doing the decompression valve mod and the quality is still amazing! He did the head of my 94 CR500 back in March 2015. I cannot believe how awesome this mod has been... XR100 style starts -every- …

Dec 3, 2017 · Anyone else running a Lectron carb on their CR500, how does it run, any problems? I have a fresh rebuilt 1998 500 and after trying to set the pj I decided to try out a 40mm lectron. I have a fresh rebuilt 1998 500 and after trying to set the pj I …

Jun 6, 2023 · A little background, a buddy brought me a CR500 engine some time ago to assemble. I work on a lot of bikes, but these old big bores are not in my shop often.

Oct 29, 2017 · So I acquired a 1989 cr500, needs a top end and all bearings and seals for the motor. 10 years ago my best friend bought it off a family member with a leaking sprocket shaft seal.

Mar 1, 2014 · Thanks for the info. The Fatty I have has the double skin on the u-section by the stator cover and looks as if it will fit my AF project just fine. I am glad that the pipe is beefed up a bit, I still remember bending the hell out of the OEM pipe on my '87 CR500 back in the day with just a simple tip over to the left in a right hander.
