well, theres two things about what I said. one was that my files (normaly harden steel dual cutting files) can cut chrome but they can not cut timing because of their size, if the ports where about 2-3 times bigger then what they are then they would work, but diamond files are best/easiest way for modding timing.



I see what you mean now.... just seemed we were talking in circles LOL

I try to head strait, or at a stand still, the only time I like to go in circles is around a track, or reading somthing I really want to learn (like modding timing )

Status: offline 		well i have 2 questions. i have an os rg 21. first if i put fangs on the sleeve so the motor gets better fuel, air mix does this mean that i will have to lean the motor more? second if i fill the shaft with expoxy and reshape it would this give me better fuel economy? also, why wouldn't u polish the sleeve when do modding it?

I have used JB weld, but was always wondering if it would hold. So far it has, but recently I started using flowable silicone...the runny stuff that's used to seep under windshield trim and seal the water leaks around a cars windshield/rear window.
