Many thanks for lookin' into this!
Youre using the most powerfull combination. In order to increase mileage you can switch to 2031 or 2015 and maintain the conycal header. The performance will decrease a bit (not too much)
If youre racing a mrx4 check the tank capacity most of them are too small even 120 cm3
You can open them a bit with a hot curved metal surface from the inside to the outside.
If you still get out of fuel in a heat think in getting a semi conycal header or a conventional header but that woul reduce the overall performance considerably.
You can also alter the gearing, latest tendences is that with shorter gearing the mileage is increase although it would seem the opposite.
Also a too loose clutch setting increases a lot the fuel consumption, check that also.
best regards and good races!
