Pilots mainly ... OK so I can send you refund ... if you must have it immediately.
Else I'll have it by thursday ...
Cool.

Speaking of which...

I'm having a bit of trouble sorting out the effects of the pilot jet vs. fooling with the mixture screws.

My most recent settings (before yesterday) left me pleased with the on-road performance, couldn't ask for better, and the idle was fine ONCE the bike was fully warmed up, but I wasn't happy with the warm-up. It wouldn't idle cold without a fair amount of choke, and took a long time to warm up. If I took the choke off it just tried to die. I was also getting a little "lope" when warming up. Again, once it was fully warm, it was great.

I fiddled with the mixture screws and found to my surprise that taking them further out made it worse, so I took them IN from my original settings, from 3 turns out to 2.5. Things got a lot better, but warm-up was still not as good as it was before I changed the exhaust and rejetted for that.

So, based on the fact that leaner seemed to be better, while I had things apart recently I took the jets from 22.5 to 20. As an initial setting, I took the mixture screws back out to 3 turns, thinking the jet change would be more significant.

Ran fine at speed, but warm-up was crap, and compression braking was noisy, a lot of popping. Seems now that the mixture screws make MORE difference than the change in pilot jets.

As of right now I have the screws at 2.25 turns out, runs great, warm up is fine, idle is fine. If there's any difference from the 22.5 pilots, I can't tell, except MAYBE a little more tendency to pop on compression braking... which I do a lot of. On the other hand, I've never had it NOT do SOME popping since I put the Jardine on...

What are your thoughts?  Back to 22.5 and just lean out the screws?

Idle good, take off with small throttle openings bad = pilots probably too big.
Idle bad when fully hot, take off with small throttle openings good = Pilots right, air screws too far out.
Idle low when cold and high when hot = pilot screws too far in.
I didn't read your post ... I'll post again after I read it.
Cool.

OK leave it at 20 ... I always thought 22.5 was a bit much ... 2 sizes up is the equivalent of running 42.5 in mine which I know is disaster whichever way you slice it.
20 and 2.25 and you got popping on compression braking. Its almost unavoidable I think.
BTW check for an exhaust leak that can make it pop like no tommorow.
Synch and float levels too need to be checked, as is sparkplugs. BTW 01 carbs have this weird side diaphragm right that is to prevent backfiring.
Cool.

Thanks for taking the time.

Ok, I was going back to 22.5, but maybe I'll wait and see what other changes do. Float levels were right on a few weeks ago. I was going to check the plugs today or tomorrow anyway, and now I'll double check the exhaust bolts. No other places it could be leaking that I can think of.

Runs like a bat out of hell, no problems there.. I thought the popping might have been less severe with the 22.5 pilots, but I might be imagining it. What with everything else that's been going on, it's been a couple of weeks since I've ridden.

Side diaphragm? Not on mine, I don't think... maybe on the '04+?

Later.. checked the '04 parts fiche.. yeah, there's a thing they're calling a "throttle valve", pretty sure it's a throttle-return damper like they started putting on carburetted cars in the '70s. Emissions. Of course, it also delays your compression braking, which makes the whole bike more dangerous, but the g'vt doesn't care about that.  I'll take the popping...

OK you are at that stage where you have to make 1 small change at a time and observe what it does. You know what it did at each stage ... so Have fun ... and make notes.
Cool.

I'm going with the 40 pilots , 145 mains ... if I don't find them at the local dealer (only one of the over 20 bike shops here carry parts) i'll have to order the set from sudco , obviously leaving me with an extra set . Is this what you're needing Srinath ? I can send my stock ones too if ya want ...
