Can i change the gearing on my 1981 xv920rh? Is there a company that will reproduce sprockets to the pattern needed? I would like to lower the rpm in any given gear, posibly 1 tooth larger on the front and 2 to 4 teeth smaller on the rear. Thanks for any info. bobd

Where can you get a 29t rear sprocket?  Yamaha do not produce one for the TR1??
