34 PJ's

[J.J.]

I'm about to order a set of 34PJ's from a supplier here in South Africa.

As jets and needles aren't exactly off-the-shelve items in this neck of the woods, I need a ballpark number for the order.

Just been through a shitload of searches and narrowed it down to:

 

Main 145~150

Pilot 55

Needle DEK or CEK

 

Elevation will vary from sea level to 1800ft, it's about 80Deg outside.

Stock bore/stroke

GRR port job

K&N in the box, no lid

V-Force 2

FMF Fattys

20cc Domes

 

Presently running 310~320 mains on the stock carbs depending on location.

 

Mostly wide open desert style riding.

 

Thanks,

J.J.

If jets are hard to find then I would order 145-165 or 170. You needles sound right. Get both the CEK and DEK. That way you have something to play around with.

 

What kind of intake are you going to run. If your going to run the UPP Racing rubber intake boots for the 34mm carbs then the LH carb will rub on the clutch arm. I have herd that you can fix this several ways. Reed spacers, have the carb bowl welded up(Why would you want to do that), or a Boss Racing Intake.

 

I went with the boss racing intake. It is one piece for both carbs, and it has a crossover machined in to it. It is a really trick intake.

 

I got mine off of ebay from these guys. It says that they ship only to USA but they have a phone number in there auction listing. Give them a call and see what they can do for you.

jbooker82,

 

Many thanks for taking the time to reply, it's much appreciated.

 

I haven't decided on the intake yet, (thanks for the link), I'm looking at a Modquad intake at the moment.

 

Alternatively, I'm also playing around with the idea of experimenting with different length intake tracts, hoping to increase air velocity through the carb to improve on the weak fuel signal caused by over-carbing the engine.

 

I'll definately follow your jetting recommendations thanks again!
