how do i know if my jetting is right


Recommended Posts

Need more info.

 

Your elevation, temperature you plan on riding in...and what other mods you've done to your shee.

 

We can't tell you the EXACT jetting, but...we can ball park it.

 

I've got T5's myself, K&N's without an airbox. The toomey jet kit I bought had 270 and 280 mains.

 

I have 27.5 pilots in mine now (25 stock) and 310 mains. The 290's I had in before we a tad lean....

 

Also, the toomey/dynojet needles have 6 grooves instead of the 5 on the stock needles. Put the clip in the fourth groove (4 down from the blunt end)...

 

You really should take a look at the first post here, that's Pinned. It'll point you in the right direction.

 

Here's an invaluable page I used to ball park mine, as well...

Your plugs will tell you if your jetted correctly or not. Run a few plug checks and see how the color is. You want a chocolatey color. Above all, your plugs are a direct link to how your motor is jetted.
