Cool Head Dome Question

[HighFlyer]

I'm sure it's been asked but I can't find the anwser.

 

Can I run good pump gas with 20cc domes?

All depends on your elevation,Squish and timing

[06specialedition]

Whats your elevation?

[vbanshee]

it works just fine on mine

[HighFlyer]

Whats your elevation?

 

 

I'm in Medina, Ohio and at 1089 ft

Not so much the squish, but more so the trapped comp ratio.

I think at that elevation you would be ok with 93 octane but at sea level you are on that fine line.imo

what pipes are you running, and is the timing stock? you can do it with the .050" squish, stock timing, and mid or mid-top pipes, but you cannot go lean at all, and don't run old gas

Ive got 20 doms.I wanted to run pump gas aswell,but after my build i have around 175 psi.So im running 50/50.Some say i should be running strait race gas.Im at sealevel.I hear 20 is the cut-off on pump fuel, usually.

FMF Gold Series pipes and stock timming. 32:1 klotz. I ride everyday so gas never gets old.

 

How do you check squish?

 

What shold be the max trapped comp ratio?

This topic always make me laugh. ran 18cc domes +4 timing, t6, vforce reeds all on pump gas. Elevation is 2500 and this bike even was in glamis, elevation 355. Bike ran like a champ no problems and we drag race the bike every weekend.
