I'm trying to get this thing perfect now that it charges and goes. i adjusted the timing with a light and it is right on. I still seem a little rich for mid range. I got the stock pilots and still have whatever needles were on the bike. I have moved the needle stop to the top position. The plug is a chocolate brown colour. It still seems to be weak in the mid throttle position and after accelerating, it sputters and then picks up and smoothes out down low and then will pulls again. it doesn't take off like a scared rabbit like it should. Yes, It could be my incredible bulk, but I doubt it. I have done the air screws as per mraxl and it seems good as described there.
There is no hesitation from idle when you blip the throttle.
The local Kaw dealer has NLA beside the stock needles because I thought it was worth a try to finally get going right. Parts list says the needles are 16009-049. 5DJ19.
It has Wirges and pod filters. Mains , I don't know what they are but Andre said that that is the size he uses for this pipe and filter set up. But honestly it seems that it is more the mid rather than the high range that it is not right in.

It would be very abnormal to have the clip in the top position. Usual would be middle or one lower.
PS: The sputtering is likely that you are running lean and doing so for an extended period will hole a piston.

Hi dale
i don't know if the PO used the slider or parts for the H1F on the H1B carbs. It could be any kind of a mish mash. I will put them back to the middle and try again. The plug colour seems OK though but performance sure doesn't

Plug color means nothing unless you start with new plugs and do a plug chop at the end of a run at constant throttle position. Even then you need to look at the color inside the tip.

Dave, it sounds lean on the pilot...maybe you should go up one size.

You may have a miss-mash of parts in your carbs. The H1 carbs varied over the years with main size, pilot size, slide cut, needle jet, and jet needle. The last three of these item REALLY effect your mid range behavior, that your are trying to now adjust. I suggest you check the resource site to be sure you have a set up with matching needle jets/needles and slide cut before trying to dial it in. kawtriple.com/mraxl/carbspec.htmlJ

I checked and the carbs are the same and needles the same for H1B and H1F which are the 2 bikes blended here. I tried to read the numbers on the needle and it looks like a SDJ19 and the pilots are #30 and new. I put the clips back at position 4 first and then 3 and it bogs like crazy. I am getting a tiny bit sick of this. What is up on the pilot size#35?

Where is your timing set at?

As per book. .1358 BTDC actually a light .136 I did it statically using a points resistance gauge and then used a timing light. I had to retard it slightly to line up the marks.

Yes, the #35 would be the one to try. The fact that moving the needle clip has a big impact has me stumped a bit, that shouldn't have much bearing until bigger throttle openings.. If the needle position impacts the problem that much it may be the main circuit that is lean -- which means you need bigger mains I have various main jets if you want to borrow some to try -- let me know. I have some stock jet needles too.

It happens when I boot it down the street. I start off in 1st and goose it. I expect to go cleanly up to the magic take off point of 5500 but it chokes out before that. maybe it is the mains. Obviously, I'm no expert. If you wouldn't mind, i'll come by if you're at work tomorrow and borrow some. Thanks Dave

Considering Wirges and pods, what size mains would you guys think I would need? I have 2 sets here, 92's and 95's. I don't know what's in there now.

Be sure you have 04 needle jets fitted and slides with a "2" cutout then(marked on the bottom of the slide). Be sure the "choke" plungers are fully seated (not being hung up with cables). Have you tried a flow check from the petcock with the lines off the carbs? Try selecting "prime" so it flows all the time rather than automatically shutting off. Be sure the tank is venting properly too. Be sure the float levels are set to spec. (23-25mm off bare gasket surface (beside the ridge) with carb inverted). To test for lean situe (provided the bowls are being filled properly) a slight stab of "choke" may be applied. If the engine picks up you are indeed lean. If it dies further you're rich. I'm guessing somewhere around 100-105 mains. Wirges are reported to clog up if an internal baffle if fitted. This will stifle the thing if bad enough. Do you have stock exhausts to try? Can you nurse high rpms (while riding) out of it by gently applying small throttle openings? A properly running H1 can easily pull redline with a quarter to half throttle (without getting into the main circuits) in the lower gears. J

I've got some 110's and some #35 pilots....drop on by!
