Default Re: Do I have performance issues or do i just expect to much?

I think that you are dealing with the limitations of the engine set up and the gearing. One thing you might try is looking at a "tuned "pipe. It effectively doubled my horsepower, But it set it up so that the power curve was a lot steeper.

Something else you might look at is the rear cog. I went with a 36 tooth. It requires more pedaling but it goes faster.

I went with a higher pressure tires with a smaller diameter cross section. Lower rolling resistance and less mass to get moving.

Lastly what I did was to try to get the body position lower and more like a road bike. The biggest amount of power once you get above 15 mph is the air drag. I dropped my handle bars by three inches and gained five miles an hour.
