Rtx to xtx conversion

well at the speeds we where running (65mph ish) with it geared 18/41 with 8 tooth drivers it was running in the 12-15 mpg range. last season geared the same but 9 tooth drivers, it would run a bit better milage than my apex whitch usually runs in the 15-19 mpg range depending on throttle abuse. apex 1-1/4 track was slipping in the conditions but the 1-1/2 on the phazer was hooking really good with almost no track slip. i am re-gearing it to stock 2015 phazer xtx specs at 19/41 with 8 tooth drivers whitch should get me out of 2 stroke fuel milage range. the 800 axis that was with us got better fuel milage than the phazer and we where not as hard on the throttle as he was.
 

and we gps'd it and it is reading high about 10kph compared to actual speed with the 8 tooth drivers.
