So i would be glad if you could tell me.
Hey Ratbone, sorry for the delay on the reply - was programming and launching a motorbike zombie bike battle contest lol - so I didn't get to tinker at all the last little while.

The 150 mains where way too rich as mikeinva and others guess it would be.

I bumped it down to 145 mains - i don't have an a/f at home but the plugs were looking a tad hot after a lengthy ride. (either from jetting or timing issues or both...)

So I richened the jet needle up and its running great (so far). Starts great, pulls steady throughout the mid range. (havent been on highway yet)

60 pilot
145 main
Clip postion 4 (2 grooves showing from the bottom.)

Tomorrow I plan get the a/f gauge on it to dial it in using mikeinva's techniques but this seems good so far.

glad you got it going your way now .Dont put to much into reading plugs on these bikes with the fuel we have now.When you think the plugs look right about 8 out of 10 times you will be to rich.

Good to know The shop was closed for a holiday so again I didn't get a chance to test the a/f gauge

I like the lm2 myself its is very easy to get the tune just right with the play back that you can use on your home puter.Its easy to see whats going on and when its going on.I wish I was smart enough to post a play back movie with play back speed slowed down on here .It show the real deal and its easy to use.On the play back you see a a/f gauge and a tach .You can watch the a/f change as the tach goes up in rpms you can freeze the play back at any point in the run.I like that much better then the charts.

Mike,

How well does your LM2 work on picking up the engine RPM? On the dyno it always seems hit or miss on picking up the tach signal on our bikes.

DOUG it works way better then the pick up on the dyno I wire mine to the tach wire coming out of the igniter (red wire) so it works as good as the tach on the bike.
I know what you mean though I catch hell getting rpms to read right on the dyno and cant figure why I been wanting to call dyno jet and see if they have any tips,some times it seams to work good other times I have gave up and told the guy to just use the mph chart and dont get a torque reading it sure sucks.BUT i will say that when the dyno works the lm2,the tach on the bike and the tach on the dyno all read pretty close to the same.

Mike,

Thanks for the info. Still on the fence on a LM2 vs. a single gauge unit, having the ability to log would be really nice. I spoke to Dyno Jet, and they said it was a grounding issue which made sense to me since I've had that with certain engine dyno's in the past. So we hooked up extra external grounds and it did absolutely nothing.

Doug

lol I ran a wire from the neg battery post I was thinking the same thing and it didnt help a bit ether.I kinda wonder if its something that goes on at high rpms with it being a wasted spark system .I hooked up my timing light to the bike once it would work the light good untill about 3000 rpms then the light would just quit working.I tired changeing plug wires ,coils boxes nothing seams to help at all.Maybe there is something strange with how these thing fire at high rpms dang if i know does not make since.
