Freaking pilot circuit...

[Kurlon]

I swear, if I so much as look at my Yam it clogs the pilot jet. It's come down to cleaning it before every ride, or just living with a high idle setting... so far high idle is winning.

Is this a trait of the old Mikuni VM running premix or just commentary on the crap gas we get nowadays?

My wifes family all has yamaha grizzlies, and they get cloged alllll the time from the bad gas. I think there was actually a needle made from a different material yamaha released. this was for wheelers, but may be the same for you. With 5 different wheelers, it was like at least one was clogged up each week.

I know that it's not a 2-stroke, but the Ninjette used to do that (along with idling like crap). Turns out that the pilot screw didn't have enough turns out (ha ha).

I turned it all of the way in the first time I cleaned the carbs, but forgot to reset it afterwards. 2.5 turns out, happy bike.

Pilot circuits are for pussies...

[DynoTune]

DRZ used to do that I replaced pilot jet with 2 sizes bigger

SUDCO

Put on good fuel filter ACE HARDWARE

Never did it again, more power , faster starting

F*n the ECO-Taliban... priceless

Heh, I just downsized the pilot as it's stupid fat on bottom. Now it's lean when it gets there due to a clogged pilot buuuuut.... screw it I'm rigging EFI for it.

[Paul_E_D]

fatten the pilot, lean the needle. It's the way of dirt jetting...

Use a fuel filter with a brass element inside and switch to a different gas station.

That and I'm replacing the who knows how old rubber fuel line with something made in this decade. How's Tygon holding up to ethanol these days?

[Fast_Eddie]

I had to use a blue plastic line similar to Tygon and I haven't had any issues and I don't believe it's softened at all. I think mine is a Moose brand tubing intended for the gas cap vent.
