you guys think on a stock 05 f4i running 112 leaded would cause any problems or should I mix it 50/50

 

I think it requires 86 or 87 octane. Why 112? Just out of curiosity...

 

well my buddy has a barrel full so why not use it if I can get it for free

 

My guess is that it wouldn't run very good at all and there would be no reason to. I think I would just stick to 87.

 

I ran race gas in my old 600 Hurricane one time and the end of the exhaust turned white. It ran a little worse if anything. Probably would've had to rejet to get it running right.

For you I'd try 50/50.

 

I don't think it would be a good idea. If you used a quart or something mixed with a full tank it might be the same as running one of those carb/fuel injection cleaner bottles through the system...also, how long has this bottle been sitting? Is it old gas? If its been stored for over 3-6 months you may introduce water into the fuel system with it as well.

 

well he actually had if for like a week..... mine seems to run a little better just worried about my internals since it burns hotter. So 50/50 would be best not a full tank?

 

I sometimes purchase fuel from the airport. Its 107 Octane and mix 1 part 107 and 3 parts 97 Octane. I never put anything lower than 97 in the bike. It runs just fine.

 

DT, massive lead in avgas, if your tune goes off, check your plugs, whiskering, wierd depoisits... Clean and free, Ripp'n

 

I wouldn't purchase anything more than 87. If anything, the machine will prob. run worse.
