Hey guys...I want to Mod my 2006 with a Full Muzzy with Quite kit and Jets (and Shims).
What (Where) is the best source for these items?
I would prefer to get all needed parts at one place.
Thanks!

 

I just bought my Dynojet kit straight from Dynojet... dunno where you'd buy just jets from other than through the dealer.

As for the Muzzy exhaust, I've been searching for the best deal on the full Muzzy, and most places sell them at the same price. Here's one that I found that sells the exhaust and the QuietKit + spark arrester

If anyone else knows of a better place to buy a full Muzzy I'm curious, lookin' for the best deal.

 

So will that exhaust and the Stage 2 jet kit for the klx 300 97-07 also fit the 09, or is the jet kit a different one? Thanks for any help.

 

Yes it all fits.

 

good to know, because I see on that site their dyno kit is on sale. I think I MAY get that. However, it said it was for the KLX 300, but if its the same thing as the KLX 250S then its all good.

Question though, what is the smallest main jet in that kit...wouldn't it have to be way oversized? Doesnt a stock United States non-California KLX 250S have a 118 main in it from the factory?

I would also imagine that a '09 250S jet kit would fit a 96-97 carb/bike too wouldn't it?

Yes you are correct.
Tip. Throw the #118 jet in the trash.
You'll need the #128 or #132. Perhaps the #125 if you're at altitude.

 

Thanks for the info. I Live at around 1100 ft. and thats the lowest I go and I go as high as 2200 (Approximately of course, give or take a 100 ft or so).

From what i've read the #128 main will be a good start for you. (stock #35 pilot.)

 

All good info, I live at sea level but ride as high as 1500 to 2000 ft so I suppose the 128 jet would be the right choice?

 

I live at sea level, never really ride higher than a few hundred feet above it, and I am using the 128 mainjet and I've only removed the snorkel from the airbox. I say the 128 jet is a good choice for those altitutdes, though someone else may correct me. With a full exhaust you'll probably want the 132 at sea level.
