Question on changing Jets

Prolly a dumb question but a question none the less, Can you access the main and pilot jet through the drain plug or do I have to take the whole bowl off?

Oh yeah this is on a 08 yz 250

Yes you can get it through the plug. 8mm and a reg screwdriver.

Thanks Greg

8mm?

All the main jets I have seen are 6mm :ride:

If you're going to change main and pilot from the drain hole, be very careful. Between trying to get the screwdriver on the pilot, the interference with the chain and the low visibility, they can be easy to get cross threaded.

you are right...my mistake.

remove the sprocket cover/case guard and the access is greatly improved.
