Topic: CR29 special Carb setup

[SunLar]

I almost got my bike together and looking for suggestion how to set up my keihin CR29 carbs.

I run 810cc piston, portet head, Action Four SS-1 cam, 4 into 2 open exhaust.
Current setup on carbs, mains 120, yy-8 needle in 3 pos.

i use cr29s in an 810 kawasaki four, so guess setup is somewhat comparable...

130 mains, clip in 4th from top,

needle? never looked

but seriuosly, no setup is like the other,

so, best way to find the best main jet (that should be your starting point) is to do a few runs on the dyno till you find best power. needle height is more something you refine during riding.

I'm not a carb specialist as the other guys here....
I ran my carbs on Dyno and jets looked OK.  Mikuni TMR32
Dyno for full throttle did not cover street or cruising on the roads for an hour or 3. I had to jet pilot jets richer due to hesitation when taking off at start and low throttle lift as driving 70-90km/h on 4-5:th gear running hot.
- Dyno for full throttle + cruising on the streets to verify pilot jets and air /fuel screws. If you do not know.
KN Pod filters or velocity stacks?
I should jet as turboguzzi. Better to start too rich than too lean. If you have same setup of pods or stacks

I'm running KN pods, think I will start with the setup the carbs came with. I have a set of 130 mains i can swap to if the 120 are to lean. I'm still waiting on a new APE clutch. (Last thing before startup)
