Idle Dies Down
tomasaki:
Thanks Guys!!! It'll be an easy thing to try to run the Mobil 1 MX2T at 40:1 instead of 32:1. I guess 32:1 is only necessary if you're running hard. I just fart around in the woods at low rpm's. I'll bet if I run 40:1 with a BR7ES plug, it should stay fairly clean. I'll let you all know.

Tomasaki, I've run 40:1 on a BR7ES for 18 months. The bike still fires up on the first or second kick. I use Maxima Super M
tomasaki:
Thanks KX500!!! I'll be trying this 40:1, BR7ES combo this weekend. I'll let you all know how it works out!!

I had a chance to ride this weekend with the new 52 slow jet. I run MX2T @ 40:1, 1.5 turns on the idle mix and a #8 plug. When I got home I let the bike sit and idle and idle it did. No sign of dying out at all.
tomasaki:
I tried the 40:1 mix with b7es plug and didn't see any difference. The plug was still black at the end of the day. Performance was good as usual. However, it still won't idle for long no matter what pilot I put in. I've tried 48, 52, 55, 58, 60, &62 pilots. The only difference I get is runaway revving with less than a 58. I'll stick with the 58 for now. I cut some of the spring off of the idle screw so I can turn it in further. This seemed to give me some more idle. I'll have to see next ride. The problem with having the idle screw in so far is the rpm's don't want to come down right away when I let off the gas.
I took out the reed valve and cleaned it. It was a little gunked up, but that didn't fix it either. Would a lighter reed valve help??? Like low tension carbon fiber maybe??? I was just thinking maybe the stock reed valve is a bit heavy and doesn't respond well at an idle. Does this make sense??? :?:
