just bought a set of keihin pwk 35mm

[chevrolet banshee]

i just bought a set of keihin 35mm pwk cards for my banshee need to get a idea of what main jet i will be around i live at 2500 - 3000ft and will run k&n filters and fmf pipes

thanks

i hope some one can help me

I would say a 52 poilet jet and a 152 main jet should be a good starting point. Rember you are going to have to use different kinds of jets then the stock carbs use.

Are they the Air Striker's or regular PWK's. Air strikers have i believe 4 vents per carb and some funny looking fins in the front side of the carb. (air box or filter side).

 

Do you have any porting or anything? Just pipes?

 

If so I would start out with a 48 pilot (probably end up at 45 or 42)

152 Main like said above

thay are just normal pwk's and i have no porting

thanks for the help

i run 160 mains and 45 pilots at 1000 feet. so im assuming since youre at a higher elevation youll need less fuel. i think you should start at around 155 main and 42 pilot.

i'ii go get a bunch of jets arond theas sizes

i have not had very much exp. with jetting so ecuse me for this stupid q.

why do you use differnet jets for the above application compared to stock?

thanksl

Stock carbs are Mikuni. He has Keihin. They use a different numbering system for there jets. Mikuni uses how many cc's of fuel they will flow in 1 minute. I think keihin numbers there's acording to the actual size of the hole in the jet.

thanks for the help" 35's are way too much carb for your application.It will run allot better with the stockers.

CEL Needle (2nd clip) 155 mains 52 pilots

 

I'm at 3009 feet and ive noticed if i go any lower than that the 2nd clip works better, i run middle 3rd (middle) although. I like oil :biggrin:

Also im in very low humidity and a 80-110 degrees variance..

I was thinking the same thing..

 

35's with no port work is way over carbed. I'd suggest staying with stock carbs until you get some motor work.

It will be faster and snappier with stock carbs....go back.

Yep....I was looking for porting in the sig... Add his high elevation onto that...and it's really overcarb'd.

 

I hate stockers....but, they do well for non-ported bikes. 30mm is the largest carb I recommend for non-ported motors.

 

I see in your sig you had a single 35PWK...how come you're going with duals??
