I want to buy a Keihin 39PWK in europe (cheaper shipping bill) for me!
my question is anybody knows what the jetting spec is on c.k. 145 altitude?
Franks thank you for asking this, I am wanting to set up a spot in Tech Talk on Carburetor jetting asking members to post make of what quad, year, mods to engine, carburetor, size, what slide, what needle, clip location, pilot size, main jet size, air screw turns, with elevation and location, this would help out so many members get into the "Ball Park" on jetting.
Yes, doing this again at least gives the other members a ballpark idea on what to shoot for.
i think the best way to find out our starting point to start the monster is that you know what is my altitude ?
when engine is running
you can start the finetuning for the mods that you have on your Quad.
i have an oem mikuni 38 flatside main jet is 360 and the pilot is 1,5 at altitude 145 m oversea
this setup is maybe good running and start cold very well 1kick
think the engine needs more air and fuel on the top rpm's
keihin pwk is maybe the best and cheapest for powerfull ride anytime judt i need the setup for alt 145 m.
Frank
i have a little clip of mine how to start the zilla cold
how can i add this ?
Frank, what pipe and reeds? They will change your base jetting.
oh sorry
i thought the man looks in the pics.
bore : 87,50
pipe : Paul Turner
silencer : Fat Boy then a mod silencer Opel City 60 HP
reeds: VForce 3
carb: oem 38 Mikuni stock needle , on the second from above, 360 main, 1.5 pilot jet, air screw 2 out
no porting
altitude: 145 m oversea
the idle dies after 30 seconds
Along with the Iron Cross, you guys must have iron soles in your sneakers. I can't do that on mine. Also you are lucky to be able to street ride.
I would love to ride my 2-stroke on the steet, well legally I guess. lol
Here at sea level +/- 100' , 88 cyl &head stock
39pwk , 185 main, 60 pilot, 6 slide, dgh needle, clip in the middle, 1.5 air screw,
Guys, 145 M is roughly 450 feet. Give or take a few feet.
thanks mutch el diablo

i think it's the same numbers of jets from Mik to Kei ?
Frank, the Mikuni & Kehin carburetors take different styles of jets with different numbers. We are collecting more information on carburetors & jetting and are posting this on a standard format sheet found elswhere here in the forum. Hopefully someone here has a combination similar to yours that rides at or near the same altitude.
