I've got the heads ported, V&H full exhaust and K&N filter.
So what to you sounds most appropriate?
sounds like stage 3 to me. mine came with all the pieces for either in the kit and the instructions in there gave recomendations on which stage to use if you have thing 1, thing 2, and/or thing 3. i've never rejetted before, and the instructions were pretty easy to follow. hope that helps.
How did you do all that stuff and not habve re-jetted already? :?
No, We're waiting to swap engines, but I got all the goodies for when the job gets done
Sorry to kinds hijack this thread but....
I had a stage three in my bike when i got it. I couldn't get it tunned in right so i oppted to go with micuni jetts. Now its way closer but i am still having a little trouble. I realized today that i still have the lttle white plugs in the diaphrams. My question is what do these do? How would they effect my jetting? should I take them back out?
Those plugs make the slide lift slower. If the bike reacts fine when you whack open the throttle then leave them there. I have not had to put them in some 4 bikes I have done... but 2 bikes needed it. No harm having it there usually. Now what setup are you running... and you dont have DJ needles with mikuni jets do you. Those DJ needles are kooky... I dont think they are as good as mikuni stock ones.
Cool.

The reason I am asking about the plugs is because my set up is strange compared to most.
I have V&H full system, k&N pod
Current jetting = 3 turns (about), 40 pilots, no washers, and 137.5 mains, floats set correctly
Problem = Slight Flat spot, or bogging thru 5 - 6k rpms
If i run WOT in say 2nd or 3rd from 2k-10k it will blow thru that range fast enought to hardly notice. It is alot more noticable in say forth gear and i am cruising at 5k rpms at half throtle.
The wierd part about it is, origingally i had 145 mains with 2 washers. My problem was much worse. I went down to 137.5 with 1 washer and it got better. Then i removed the last washer to give me my current setup and my current level of performence.
My plugs are a carmal-brown color on the porcelin, but on the metal tip i have a more whiteish color?
SUGGESTIONS PLAESE!!!!
AND MIKUNI NEEDLES
Try 135 mains... however. You might have to go with different carbs entirely... Yes yes guys dont jump on my back now... head work or bore work often results in higher velocities in the carb throats... that makes the vacuum higher making it suck more fuel out... hence smaller jets. Ok down to 135... its a bit of a surprise to me but how drastic the work is makes it well possible. But the final limit is the carbs overall throat diameter and the resulting possible max velocity. Anyway There is a way to lower the needle below the stock location too... sand off the spacer... Before doing that measure the thickness of it, and sand off ~ 1mm off the spacers. Then you can bring it back to stock with the addition of those washers... or get rid of the spacer and compensate with washers till you are 1mm below where it was... Make sense. You still may be a touch rich on the needle... and of course it behaves in the lower gears... the last final tuning of jetting can only be done in top gear. It cleans up in lower gears long before you get even close to ideal.
Cool.

Are you sugesting my bike has had some head work done?
I will try your suggestion with the washer/spacers.
Oh no I thought South east rocket was you... on a all stock bike you are feeling rich at 137.5... and it improved when you went from 145 to 137.5... Oh... that is weird... sure the needles are stock. Hell with that... I'll send you needles stock ones... try that and let me know. And send your needles back to me... I would like to fool around with that. DJ kit needles will make 135 about right... stock needles no way... unless your floats are set 6mm or so high.
Cool.
Srinath.
Thanks for the offer, but I am sure I have stock needles. I ordered them from the Suzuki dealer. Also I thought it might be the floats too, so I checked them (not the U tube method) they seamed to be right or at least real close to right. Maybe at most 1 mm off. I guess I will just keep experimenting with more jetts. It really sucks because I keep buying all these jetts and wasting money!
K&N pod... the kind that covers both carb openings looking like a lunch box... or one that goes in the airbox... If its airbox... you need to be at 127.5.
Cool.
Srinath.
the one that goes over both carbs
No idea is all I have to say. Float mey still be too high... ~5-6mm... but its impossible to have it that high wihtout it spilling into the air filter. Somehitng will work though and years later we may even know why...
Cool.
Srinath.
Choke staying open is another possibility.
Cool.
