Hi
Did a few Things now. Jetting side is now towards the Engine. Throttle on left side.
Crossover is closed
60 mikuni in y Return line
Rebuild carbs.
My setup
135 Main
115 Low
2,3
95 Gramm
My total loss is
29 Static
5000 retard
8000 rev. Limiter
17 degree at 7000 rpm
I got dark Brown plugs. Little Bit to Rich i guess. It Runs Strong Low, and Strong Top, but acclrration Takes some Time.
Can my Problem be my impeller? I Rode a standart One i think. 13/17 or what is this?
Is this to Big, that iam overproped?
My setup
Full ported 760
48 novis
Vforce 2
135 psi
95 fuel
Power factory pipe
Total loss
Small coupler

When you say 'acceleration takes some time' do you mean it's revving up but not really going anywhere? If so, then ya I'd say you're over propped.
its like,
it feels like a good bottom,a weak mid and a good high.
When i get about 5000-6000 rpm it goes hard forward. But i need the engine for freestyle and under 5000 rpm. Iam not sure if its jetting, impeller, or Power Factor Pipe that need rpm...
Ill try reverse jetting now to low 135 and high 115 or sth like this. And i order an Impeller, but not sure about 9/15 or 10/16

135psi is pretty low compression, worn out pistons would explain the rattling in the engine mentioned earlier. Stock compression should be around 150/155psi.

Compression is always taken cold
Small Update
I just ride it with
115 low
135 high
2.3
95 Gr.
It was just not like i want it
I switched to reverse jetting
130 low
115 high
it runs good now. I only have the Problem that i have 1 brown plug, and 1 black. I read about it, that Pto and Mag carb must be tuned different sometimes. How can i find out if its the low, high or adjustment screw? Its the Rear Zylinder thats running rich.
And next Problem. How do i tune the PFP right? It needs to be hand warm or sht like this?
