It's surging between 6-7k. Been having lots of tuning problems, cant seem to get it to have good part throttle driveability. I'm about to go back to stock. Some people with this combo run 20/62.5/142.5 and some run 20/65/147.5. Who's right? 

So does anyone have jetting for Jardine system and stock airbox? 20/60/135 with 0-2 washers might work?

runs much better now. needs very little choke. I'm wondering if i could use slightly larger mains.

Runs like stock, which is a good thing, because it ran great. Warms up a little faster and requires a little less choke. I didn't even have to adjust the idle. I also got some 140 mains I might try just to make sure the 142.5 isn't too much. I still have some testing/confirmation to do, but it seems awesome.

Warms up quicker, needs about quarter to half choke on a warm day and about three quarter choke on colder days for here (40's 50's). No flat spots. Power down to about 1600 rpms. more low end.

• Runs great! Sounds like a real bike now!  Takes off quicker at lower RPM's! Runs smooth, although I may give the air pilot screw a tiny adjustment later to make a tad richer. No hang ups on RPM's either. And the rejetting tutorial on beercangarage made it easy.

Runs happy all the time so far. Hot/Cool (no cold weather start yet). I have usable power down to about 2k now where that would have been a mandatory downshift before (probably still good idea to downshift that low). Seems like it pulls better at all RPM's, but especially <5000 and >9000. I don't feel like I need to shift as often. Lean surging at cruising speeds is mostly gone.
Before new jets I needed choke every cold start, even in the afternoon. Needed to give it minimum 30-60 seconds to warm up or it would bog down under load taking off.
After new jets I don't "require" the choke for summer morning starts, and I can leave immediately after starting without issue. I recommend a little choke and warmup time for other reasons however. I'm curious to see how it handles in a really cold morning start. I expect it will need choke, but be better than before.

Runs excellent! 

Have read all the jetting differences and find 2 things missing.1 float level height  and..2 if the ignition timing has been changed .these would have a large effect on jet change results .Also what spark plug being used..

First n00b post!

-K&N drop-in (no restrictor)
-Yoshimura TRS slip-on
-Dynojet stage 1 pilot jets (18.5 ?) / 62.5 / 137.5
-3 turns

Only have 3 full days on the new setup, but so far it seems a very good combo with smooth acceleration and greatly improved throttle response.  I grabbed a pair of 140 mains as well
when I got the TRS, but doubt I will need to put them in, as she pulls strong through the upper RPMs with no flat spots.

Also switched to NGK DPR9EIX-9 iridium plugs at the same time, and the first plug read is great! 
I felt comfortable switching to the #9 heat range, as platinum/iridium plugs run approx. 1/2 heat range hotter than their copper siblings, and car tuning has consistently shown me that stock heat range plugs on modified engines is a no-no.

Bump for good info

Hey, I thought I'd post my info even though I'm still having trouble with it (perhaps BECAUSE I'm having trouble with it).

Washers 1.5mm

Runs great until I'm about around 90-95kph+ then there're lots of fluctuations with speed (almost as if it's just about to run out of petrol). After much testing with settings, jets and swapping valve shims I've come to the conclusion it's because there's no velocity chamber/air box.
Slapping a filter directly onto a carburettor is not a good idea as it doesn't steady the air. When the wind starts getting blustery the air intake is no longer consistent, giving questionable performance once you're out of the suburbs.
Unfortunate that it's taken me this long to come to that conclusion as I'll be having to ride 1400kms before I can even have another look at the engine.

I'll repost here once I get something that works.
I'm missing vacuum port o-rings, apparently. Also I remove the frame-mounted tap and just plugged the tank straight into the carb which helped a lot.

You should have started your own thread for this, it will get more replies. As for the problem, it is one of two things:
1. The drain hose for the carbs is facing into the wind, creating a negative pressure in the carbs, leading to fuel starvation.
2. You have the stock petcock which is vacuum operated and is known for starving fuel at higher speeds (one of the fuel openings in the petcock is too small of a bore).

This thread is only for people who have GOOD jet settings so that others may use their settings.

The search box in the top right of the screen will always yield some good results based on keywords. Good luck 

1998 w K&N Drop in w/ restrictor - 40/125, 1 washer on needles. 
-Note: It starts great at full choke.  Once the RPMs jump up, it's hard to find a setting for the choke that won't either make it die or stay really high.  Once the engine is warm, all is well in the world and it idles at 1200 RPM confidently.

Plugs tell me slightly rich especially at idle, but I ride year round.  Helps in Winter and quicker warm-ups.

Make sure your carb is clean, free of air leaks, and valves are PERFECT, otherwise you will never be able to tune your bike.  Ask me how I know this.
