Guys I think it is good to error on the side of caution, that being said, I have been spraying a 50 shot since the bike was new in Sept. of 06. I have always run premium pump gas and let her eat. There is no need to pull timing until you cross the 50hp threshold. The most important thing is a good map to ensure you are getting the proper amount of fuel. I finally pulled the head just due to the amount of nos passed on the bike and everything looked fantastic. I run my spray through a Schnitz two knob controller and bring it in slowly so I don't hit anything hard inside the motor. I put springs in the head and put it back together. Ready for a few more years of flogging. These things are engineering marvels!

Well, there are exceptions to every rule I guess.

For me it wouldn't be worth risking. I have too much time and money invested in my bike. I think most would agree that it is not a good idea to spray 50 on pump gas without pulling timing.

Just curious, how long do you stay on the button? What is your a/f? How much change in rwhp when you are spraying? How slow are you bringing it in with the 2-dial?

Track results? Size of your nitrous bottle, bottle pressure, pressure regulation?

When i would spray my bike with the 40-50 shot i would try to stay out of 6th gear so i would do 1-5th gear pulls on the button gearing was 16/44, my AFRs were set at 11.8 on 101 with the 50 shot it made like 47hp over my motor did and the 40 shot made right at 39hp

on the 40 shot i picked up 8.5MPH at the track and 3 tenths, i never took the bike to the track with the 50 shot the only reason i put the 50 in was to race a turbo busa on the street, we did a 2nd gear roll and i yanked him till about 160 than he started to make his move on me.
I was giving up about 40hp to him but i had the hit of the bottle to put some distance on him before he got going

Why did you try to stay out of 6th gear!

You street/Hiway race like we do. You should have quit before he caught you :-)
