[QUOTE="snb73, post: 713940, member: 49046"] EruoDude, Try increasing the preload on your exaust valve spring. If you put more preload on the spring, the exhaust valves will open later (at higher rpm's). Keeping the exhaust valves closed longer (for more of the rpm range) should give you more usable torque and less of a hit. This won't replace a porting job, but should give the bike more low end torque for more of the rpm range. Plus it's a free mod. Hope this helps, Steve. [/QUOTE]
