Resently had thunder Mfg.tear drop air cleaner installed with Roarhouse Dooley
pipes.Had local dealer do install.They had problems with the cross over pipe
and left side bracket for that pipe causing them jetting problems,(crossover
was leaking and trying to come apart)They ngot it but pipe didn`t looked at an
odd angle.Fixed that when I got home.(Go figure)anyway bike is running good after
good warm up but has slight hesitation from 1/4 to 1/2 then good,gets better in 3rd,4th&5th gears.BIG differance in gas milage went from 36&38 mpg to 45mpg with
me and wife both on board,50 mpg by myself.Asked Mechanic today what settings he
used today,(yamaha jets)190 main,40 pilot 3turns on PMS.??? was suprized with all that I`ve read thought I would be running REALLY rich.He also said he had to use the stock needle as he had no luck with the adjustable one. I have a dynojet kit on hand if I want to make any changes,just trying to get some feed back,power is good but not the leap I was expecting????Sorry this is so long

Based on your settings I'd say you're rich but your gas mileage says different.


Interesting.

For the 04-05 with new pipes and air kit we normally recommend the DJ 180 main (Mikuni 175), the clip on the third groove from the blunt end of the needle, and the PMS about 2.5. Everyting else is stock.

This is a starting point and from there the jetting is tweaked according to your particular circumstances.

Think I`m gonn ahave to take that carb off to see for myself whats up.
Did notice today front of air cleaner and back plate not sealin well all the way around even though I know screws are all the way tight and the screws have stops to keep from getting any tighter! (It sucks that quality control sucks for products for OUR RD*`s) Thanks Doc!

What about the pilot at 40 over the 37 DynoJet supplies??<br><br>Post edited by: vegasdave, at: 2006/05/24 10:14

Leave everything else stock. You may/may not need it.

When I had the ProPipe on I did increase my pilot size but when I changed to the Nasties I put the stock back in.

Half the bikes may be running a certain set-up but that doesn't mean yours will run well at the same settings. Unfortunately the last bit of tweaking is always trial and error and that's where the frustration sometimes sets in.
