My brother is having some performance problems w/his '92 Honda CBR 600 F2. The bike only has 9K miles and doesn't run at full power until you almost run out of gas (right before you have to switch to the reserve tank) then it seems to have full power for a short period. I own the same make and model bike and notice a huge difference in the over all performance between our bikes. Anybody ever have a similar problem or familiar with this at all?
Thanks!
