for those who dislike tuning and changing jets try this out. Definitely worth the money and I gaurantee you will never have hard starting problems again, a few shots of prime (built into the FI system) and the bike will start first kick everytime. Mine starts great running E85 Ethanol.

Oh and Zigg thanks for that last post I need some of those for my purge system now that Kevin has my FI running on E85.

I have seen some people use the radiator overflow tank and run their purge from it.

I run alky in my cub. I have an aluminum tank and have always drained it to purge out of fear it would ruin the inside of the tank. It seems like the quick disconnects are a good idea. Will I run into issues if I don't drain the alky from my aluminum tank and purge through the quick disconnects.

The last time I bought alky it was only 2.80 a gallon, just fyi. What are other michiganders paying? I buy from a major oil company though not a store like duneland or whatever.

Your plugs and needles are fine. EGN seems to be the most common needle, but EGLs should be fine. I think the L has a thinner taper, making it a tad richer needle than the EGN, but not sure. Don't have that chart in front of me.

i have to ask, what is the reason for running a colder plug on methanol? if i am not mistaken, the higher the number with NGK plugs the colder range the plug is?
i am using a BR9ES on meth where as i was using 8's on gas.

edit: nevermind, i think i found the answer to my question.
methanol doesnt burn as quickly as gas so it burns longer. having a hotter plug in this type of situation will lead to detonation therefore the use of a colder range spark plug?

im on race gas completely.. have never had an issue with my bike running and the same top end has been together for over 3 years without issue. clean the carbs when it comes out of storage in the spring, and then give her hell all summer long. i suppose i may switch to something else, but for what reason if i dont have to mess with anything for 6-8 months at this point? i use the same jets in this setup no matter what the condition, and the bike seems to run pretty damn consistent(still have yet to find the right tires for it though)

i have thought about converting, but if i do, i was looking into a nitro methane and alky blend..
inside every man is a little kid who just wants to come out and play

a big thanks to these guys for all the work they have done to get this thing up and rolling
