I know what you both are saying, I would like to see what both your running mixtures are on the Dyno??

I know mine appeared to be running perfect and not doing that bad on a gallon of fuel, I took it to the Dyno and had it tested after doing something or other,

It suggested the bike was running slightly week at the lower rpm to rectify this I lifted the needle one notch,

It was after that the fuel consumption rocketed!!

I runs even better now, there is no blackening or a smell of unburnt fuel, and it runs much much cooler than it ever has.

hello Roy
i am running 203 cams with 1550 conv 9.4 comp flat top SE pistons
ported heads suppertrapp 2-1 exhaust Baker 6 speed baker and a mukuni 42 carb
and very happy with it
the big bore conv. is the way to go in my book!!
a not very expensive way to improve overall torque

john, p.s. are you going to Talgarth Roy???

Sorry Dave but I dont have that information now. I'm going back 8 years or so. I know it wasnt horribly rich or lean and seemed to be around the norm for that type of build.

Thanks for all your responses.

THis is me planning my next set of changes, probably over the winter.

One thing Dave said interested me, about balanced exhaust systems. I have a PCIII (USB), S&S teardrop but all fitted with V&H bigshots, which I don't believe is a balanced exhaust system.

Would changing this for a 2:1 make that much of a difference?

Cheers, Roy

Sorry i cant help you there, i dont do the sniffer thing with dynos, i have only ever used dynos a couple of times to find out what the figures were.
I personally think that a lot of people that run dynos think they have got you buy the nuts and you are just a means of lining their pockets.....Especially with Harley's

I have always tunned my carbs the way i see fit and always had good results and never any problems....

Fuel injection is a whole different world

Call me sceptical but i think a lot of the EFI tunning stuff is a load of old bollock an all, not all but a lot!
