I installed a Trail Tech Tach/Hour meter and took it out for a test run. It shows an idle of about 1,000 rpms when warmed up. When I run through the gears it doesn't seem like it is keeping up with the engine speed. I thought the YZ would rev higher than 5,950 which is all it is showing as max RPM when I shut down the engine. I have about 4 or 5 neatly layed wraps around the plug boot right before it drops into the head. Another question. If I were to hit the rev limiter and quickly back down, will this hurt the engine? (fresh Yamalube is in there) What is that RPM at limiter going to be? Thanks!
