1st ride with the YZ pipe on my WR Yessssir ! But what about jetting?
Posted July 17, 2003 - 01:12 PM
I feel much more "fun" out of my throttle. But I have to ask, what are the indications I have to look for proper jetting ?
Even if so far, the bike runs ok. No problem with starting, and while twisting the throttle I didn't feel any misses.
I still run stock jetting. The snorkel is removed but I left the lid "with 6 1 inch holes" so I could have a place to place the battery. I also installed a Unifilter.
I'm wondering if with my stock YZ pipe and the opened up intake, I have to go richer ? Even considering that the bike runs "OK" . May be I'm missing the best part of the blue beast if I don't ask ?
I should be running a 162 (or165) main jet,(from the dealer charts). I run near sea level up to 1500 ft. Before I do any big move I want to be sure that the trouble will be worth it!
Thanks for your infos!

An abnormal amount of popping when chopping the throttle is a sign of needing to richen your jetting.
Have fun with the newfound power and keep your tires underneath you!!!
See ya, Kelly

The bike feels really good.
I think I'd have to ride a perfectly set up bike then ride mine to see any differences .
I don't think I'll do any more mods for now... May be the James mod and the YZ timing this winter
Thanks for all the info guys.
Thanks to TT.

I run the stock jetting with my 02WR426 and the YZ pipe, 03450 cam. Runs perfectly and starts easily, grey exhaust, plug looks good.
In my opinion and experience your bike will run better with a YZ needle in there. Just depends on what you think "better" is I guess...
