330 Main

[bansheeyfz450]

I have 2000 Banshee I picked up about a month ago. This is what it has, Toomey T-5's, V-Force 3's, K&N in box no lid, cylinders are ported. The main is 330. This setup is for sea elevation. I ride @ 6000-9000 FT. I am taking off the stock box and going to run twin K&N's. It has a cool head but not sure what domes it has. The guy I bought it from said he was running 100 octane. So I am running the same 100 octane and mixing 40:1. I was thinking dropping my main jet down to 310???? What do you think?

way lower than that.... i would say in the 260-270 range for starters at 6k-9k elevation. that's a huge diffrence. you may end up going leaner than that.

Stock carbs I assume?

 

I run at about 5000FT.....aggressive dune port, CPI's, vforce, no air box W/pods...etc. I run 310 mains to give you an idea.

 

X2 with Phelps, at that elevation you will be smaller mains than me.

I see on Toomey's webpage they say to run 250's, but with ported cylinders.. 300? I dont want to blow it up? "06specialedition" 310 on your mains? Is that dyno tuned?

START AT 280 then do a plug chop..

No that is not dyno tuned. But when Brandon at Wildcard Racing build my motor, he told me I would end up at about 300-310's......and with 310's it runs like a champ!
