Going to post this in another location for more ideas.
First off at this very second I can't tell you what jets are in the carb.
I have a high compression 15:1-15.5:1 KTM 450sx-f. FCR flatslide keihin carb, with quickshot II.
Right now I'm mixing 110 race fuel and 93 at 50/50 as per my engine builder.
He has never tried any of this on methanol, so he doesn't know where to start.
Can anyone give me persay a possible amount increase in jet size from my current jetting as a good place to start, or must you know the current jetting to even begin? I will find out the jetting, just have to get to the shop and get it pulled apart to start investigating.
I'm just guessing, but I'll more than likely need to adjust both jets? Since the amount needed vs gas is higher regardless. Just wanting an idea where to start vs my current jetting. Any help would be much appreciated!
