Well, i set needles to leanest positon but with a thin plastic shim underneath. Bike run's even better but does it get enough
fuel when on pipe??
Maybe lectron carb's are the answer to my issue? Anyone here run them and have some info to share?
About ignition, a zeeltronic seem's to be a good investment as Jorgen already proved.
Jorgen: what jetting (nozzle's) do you run in your vm34's (pp. vs. reed's)
Hi.
Your cylinders.......are they Ebos??
I will take the Higgspeed measurements later today, I'm kinda slow
Regarding jetting:
It depends greatly. With my 109 rwhp reeded cylinders with Jollymoto and Ebos heads I had to use 300 mains to have the detonation within control.
I have those same cylinders on my H2B touring bike today, running Higgspeed and STOCK ignition. I use 270, and the same amount of detonation as with Jollymoto/300 mains AND retarded ign timing!! (mild detonation, only when fully warm)
The Jollymoto are prone to detonation, and a pain to tune. (4 stroking off pipes, detonation on pipes) But the kick they give when hitting powerband is amazing, same with peak power! They are really "GP" fatties. The Higgspeed are A LOT easier dealing with for everyday use!
With stock cylinders and Higgspeed I used 220 mains.
1 thing: I believe the pretty square exhaust shape of yours tend to make the returning wave "short and strong". Good for peak power, bad for middle range power as this, in combination with steep last cone shape of pipes, gives you a very strong returning wave -messing up things just before pistons closes transfers.
Do you have other pipes? Even stock pipes? I can almost guarantee if you try stock pipes the problem is solved due to the issues mention above. But then again, you got a more linear power curve, without that big hit and great peak power......
