Ok I have done a bunch of searching but would still like some opinions from those more experienced in tunning than myself.
Here's my setup....
61X/61X std bore
stock reeds
Single 44 carb OP Vortex FA
Home port job using sport port new FS templates
Coffman's Sizzler pipe
Weastcoast head - unknown dome size
- I am getting 167psi on each cylinder with a cheapo AutoZone gauge
- I imagine this might get a little better as the new rings seat etc...?
Based off my searching my starting point for carb tunning is...
2.0 NS
140 High Jet
120 Low Jet
95 gr spring
Current pop measured 30psi.
I'll have to check but I think I have my low screw set at about 1 turn out and the high screw set at 2 turns out right now
I am not really good at tunning, just don't have a lot of experience with it. I am trying to learn and get better, but would prefer not too cook my engine while learning!
I have read the mikuni manual over and over so I have a basic understanding how the circuits work together.
I just have a hard time determining lean/rich.
My plugs look pretty rich right now. I will be doing a little playing with the ski today so I thought I would ask for some help getting this thing tuned in.
Just wanted to know what you guys think about my current pop off, jetting, etc... for a starting point and any recommendations you might make. Thanks for the help. This site is the stuff!
