did that work for you ?

Thanks for the gear part number. Will aluminum wear out quickly? I understand that GEBE uses hardened steel gears.
Running out of HP is a concern, however, I am of the feeling (perhaps over exuberant) that I will be able to maintain a 32 mph speed at 6750 RPM while pedaling. I have calculated that at 25 mph the engine is at 6750 rpm. Therefore a 17 tooth should put me there (32 mph) at 6750 rpm. The question remains--will I be able to reach that desired parameter? Do you have a gear that I may be able to use/borrow to determine real application result?[/QUOTE
sorry, missed this post earlier. my experience with the gears was that at ant given rpm i'd be moving 2.5mph faster for each additional tooth.
BUT there are deminishing returns. any certain amount of HP will only move any given weight and combined frictional / air drag loss so fast and no more.
IF you have enough pedal gearing advantage and WANT to pedal full time you MIGHT be able to do 30mph with a 15T.
i don't have any extra gears at present.

Why do you want a longer drive belt?Have you ever ordered a longer drive belt? Do you have a web link and part number?
Thanks DT- I am encouraged by the fact that I can pedal and hit speeds of 32mph top speed with the 13 tooth gear. While I have a secondary interest in a top speed of 35-37, my main goal is to be able to cruise at 32mph at 6750rpm while pedaling. (hence the 17 tooth gear) Since I am able to reach that speed already it seems plausible. In any event I am on my way to order a couple of gears and then on to a machine shop. Is there anything I may need to know about the machining process, or anything else?
