[Fast Fred]

Hey 850, they was havin trouble at the Dyno shop with the fuel system,
they did not have it right. i ended up pullin them dynoed pistons out and puttin in some top-pinned ones.

she showed signs of lean, they wasn't get her enough Fuel, the carb needles
were set so they would not close, was runnin a 1inch tuna

did get a ton of info from them 4 dyno pulls, so check the Burn

was able to take the dynoed info, with some of what i know, and some help for Tim, to get it stright with out killin it.

[Fast Fred]

that is the SST60 fuel system i'm runnin.

[850cc racer]

how do you have the fuel to the carbies though!???? thats the question.

lean aye thats no good. 985f is to hot.

mines still so fat i pulled my tuna out and shortened it up i hadnt ran it in 2 weeks and it still "dripped" some oil yeh shes FAT

i have a pyro in now with jets on the way.

test test test is what ill do

im loading her up though at 6900 she needs to run to that 7400-7500 shorter tuner and not so fat and i think im there
