What more can I do (please read)
Okay I've had my motorized bike for about 4 months now and I want speed! I have a 700c thruster fixie bike. So far I've done this to it :
changed sprocket to 32 tooth
Bought a "high performance" spark plug Wire and boot
Put an NGK b6 plug
Changed out (skull shaped) air filter to new low profile filter I got from bike berry!
For my fuel I'm running a 32:1 mix. Help what more can I do I'm hitting 37mph top speed with the engine redlining ,I want a cruising speed of 37-40 mph without forcing the engine sorry but I'm not able to get a shift kit don't have that much money
