I know the bike will do 65mph no problem but o'm looking for better fuel economy seeing I comute 120 miles plus a day. Dose any one know what sprockets will fit from other bikes to help me achieve this?
Thanks ahead of time for your input.
Hello, AngloBiker, and WELCOME to KZr!
If a replacement countershaft sprocket with one more tooth is available, could install it and test run.
Acceleration will suffer, but cruising rpm might feel more relaxed.
Am doubtful about any significant difference in fuel consumption.
Would bear in mind that these engines were designed and meant to spin happily at rpm's below redline.
Better fuel economy might be better achieved by careful attention to
engine maintenance (spark plugs; valve clearances; ignition timing; clutch push rod adjustment; etc.) and
carb tuning (clean air filters; fuel level; etc.) and
chassis maintenance (tire pressure; no brake drag; chain lubed and kink-free; wheel bearings; etc.)
Good Fortune!
