28mm Keihin PWK Jetting

[Dick Wheels]

I know this has been covered a million times but every ones shee's are different and weather is different. I just ditched the single carb setup that has been on my shee since day one and grabbed a set of 28mm PWK's. Where should I start??

 

Everything I know about he bike is in my sig. thanks

[Dick Wheels]

Also what needles am i going to need

[Dick Wheels]

OK, Just got my carbs in the mail today. They have 155mains, 45 pilots and LGN needles on the 2nd to bottom clip. Where should i start with these.

 

Also if i use stock intakes with crossover tube, will they kit the clutch lever?

As far as the needle, a JJH seems to be the one sticking out in my mind (I have never used 28PWKs). I am not sure if the 28PWKs will work with the stock intakes, but I am not positive on that one. I am sure someone with more 28PWK knowledge will be more help than I am...

 

EDIT: I just did a search using the key words "28mm PWK jetting." There are a few you might be able to use to help you get it close.

 

Click me. :cool:

Im 800 asl and run 160 & 50 bored to 30mm though and as for the clutch arm its sooo close you'd be better off using spacers or??? and needle on 4th from top rich. I think I would step up the pilot to atleast 50 for winter and 160 if you have it, for the main. Then again I have pods, I think you would be safe to go with what you got and go from there. :shrug:

Not sure what they are, I have the oko's same internals basically same carb and I run the needle that came in them and cant remember what they were, sorry.

is it normal for the slides to not fully open all the way on the 28's? i know on the 34's and 35 I had the slide would basically disappear when fully open and the 28's do not. they also have a very short throw with the throttle

[Dick Wheels]

C'mon guys give up the info! I know there are a few of you on here that can just look at my mods and practically get me dead on.

What you have now sounds about right. If anything jump up on the main to be safe. I'm pretty sure my slides go all the way up on my 28's so check into that.

[Dick Wheels]

When I move the slides by hand there is still probably a 1/4 inch showing and they don't fully disappear. Its weird cause a set of 34 i had and the single 35 I had the slides would both fully disappear when fully open

[hercalmighty]

I would check and see whats holding them up because they should be totally opened. If I get a chance I will double check mine.

[Dick Wheels]

ok sounds great thanks alot. Also do the needles just "sit in there" or is there something like in the bigger carbs to hold it in tight

[hercalmighty]

Its a goofy setup that holds mine in and I dont know what the bigger carbs have
