09 xtx with stock gears and have been thinking about a trip to the Upper Penninsula. Hoping with my recent mods, and a clutch kit to come, i will get better top speed but would it make sense to gear up one tooth? How much faster would it change top speed? I would just like to be able to keep up with them long legged apexes a little better.
Thanks
 
Ran 114 mph gps on stock gears and 112 mph gps with 22/39, same conditions. Running 23/39 for now. Need time to make some speed runs and compare between 21,22 and 23. So far 21 is faster.
 
so stock is 22/39 and 21/39 is faster?
 
Ok got ya. So sofar your advice is keep it stock
 
Rikman how much tuning did you have to do with your clutch kit from ulmers? First time i rode with my mods was last night and it deffinatly has more power but im hitting like 9,200 rpms all that power and im not getting satisfaction :(
 
Your hitting 9200 rpm on take off or on top end?
 
Ha idk antwhere between 50 and 70 i guess all i was watching was the tach, not spped
