[QUOTE="Matt90GT, post: 1356622, member: 30871"] well you are about 5-10hp down on a new bike. The 05 year Honda really stepped up the motor game to over 50hp stock. I would suggest to first look at your gearing. They did a change either 04 or 05 to the 13/48. I personally run the 14/52. Just makes it a different bike. Feels like you are on the pipe all the time. Everyone that rides my bike feels the same way. FYI this is the gearing windham has run for years outdoors. second, step up to the newer 12.1:1 piston or better a 12.5:1 piston. They address the jetting. There should be no noticeable bog or hesitation. You maybe 1 tooth off on the cam timing also. Just thinking of things. Your jetting for response will be all about the accelerator pump AP circuit. Lastly, run a different exhaust. Nothing but good things about the MRD pipes. [/QUOTE]
