[QUOTE="Aholland, post: 368298, member: 32181"] The bike was originally modified by...TUF racing when you (Eric) were there. I believe that one of less skilled people did the original porting. When it first came back, it was totally unacceptable. Would'nt run worth a damn. I sent it back when I believe you worked on it. You cut the cylinder base down and re-ported it. Now it runs very strong in the mid and high range. Bottom end is a bit suspect. I measured the squish clearance with 4 pieces of solder (front, back and sides) at the same time to reduce any piston rock. I always record the clearances when I do a rebuild which is why I found it funny that they had closed up so much. This is the first time I have used a Weisco piston. Maybe the gaskets amount for a small amout of the clearance and new parts the rest. I'll increase the clearance to 0.050". This will probably drop the compression to 150 lbs which should still be okay. As a second question, Do you advise advancing the timing on these bikes (altitude 4000-6000 ft). The ignition can be advanced considerably, but I read in one or Eric's technical papers that timing should not be advanced more than 0.7mm (stator rotation). This may have only applied to the 1997 bikes in the article. I can advance mine probably about 4 mm rotation. Any suggestions guys? I never ride below 4000 ft. Thanks. [/QUOTE]
