Default Dyno results. HELP!! Questions....

I was also very concerned over drilling the extra 2 holes.
The results were great. More consistant and able to jet correctly.
If you feel that the extra 2 holes do not help, just plug them with JB Weld.

ps mister hp what consist the genesis kit you talk about on your page
I think you were dynoing on knobby tires? they broke loose just before peak torque. I would move to the 5th position on the needle and run the 195 main (the graph says 200main?) if you have both the inlet tubes removed. I'll let eric answer the genesis question and add anything about jetting.

Eric, did you catch that he is running the dyno jet kit? I agree it looks lean (and/or knobby tires). We tuned on the dynojet needle for way too long, and ended up pulling it out and using the stock needle. We just couldn't find a setting where everything was good. The dyno jet is extremely lean on the bottom and extremely rich in the mid range and top end.

Do you still have your stock needle?

thebigshow,
I have heard about their dyno, I may go try it. I think I will give LSSS one more try. I am going to perform the mods suggested abd try it again.
Carl.
