How does this quad run now with the 260 Main jet?

Does it idle and start ok?

How does it run when you are riding 1/4 to 1/2 throttle?

How does it run when you do wide open runs through the rpm range to the top end?



This is a plug chop with a barnd new plug after doing a wide open run. You have to cut "chop" the plug to read the band on the plug. You can see where one of these plugs is reading richer than the other one.

Note: Jetting is a practice of feeling how the bike runs and also some mechanical inspection. I would spend some time with googling "two stroke jetting" before going much further. There is a post on this site that was really well written too.
