Hi guys. I've searched and can't come up with the info I was looking for. What are the differences in these fuels? I have a new kxf250 and have tried Ultimate 4 with decent results. Someone suggested I try MR2 and I am unfamiliar with the differences of the 2 fuels. What fuels have you all had luck with in the little thumpers? Thank you for the help.

i think you will get the best results from the ultimate 4 in your thumper, just remember, to get the best from any fuel you may need to experiment with jetting a bit- try searching this forum, there is loads of stuff to read up on if you want.

Thanks, I thought U4 would be the better fuel. I've got the jetting pretty close, however the constantly changing weather is making that more difficult. Thanks for the help, everyone have a safe and happy holiday.
