88BANSHEERIDER Posted February 21, 2010 Report Posted February 21, 2010 i have a 89 banshee and i just pick uped a used pro design cool head for it and i am wondering what size domes i need for it. i have a 2into1 carb on it k&n airfilter fmf golds and i believe my bore size is 65 i also am 675 ft above sea level i ride alot of trails but there are some parts that i like to open it up i would also like to know what jets i am going to need to put in my main and my idle jet thanks matt Quote
captainhowdie Posted February 21, 2010 Report Posted February 21, 2010 Dome size depends on what octane gas you want to run. Go with a 21cc dome if you want to stay on pump gas. Not sure what jet size to tell you... I have nver ran a 2into1 setup. Im sure someone will chime in for that. What pipes are you running? Quote
88BANSHEERIDER Posted February 21, 2010 Author Report Posted February 21, 2010 i also forgot to add that i have my timing set at +4 i just put that in and my pipes are fmf gold good for trail riding i read on here Quote
88BANSHEERIDER Posted February 21, 2010 Author Report Posted February 21, 2010 i also forgot to add that i have my timing set at +4 i just put that in and my pipes are fmf gold good for trail riding i read on here i also am running 93 in it and have a ? about running aviation fuel threw it i live close to a reserve center and have a buddy that could prob get it for me so could i run smaller domes with this or not Quote
Burt Reynolds Posted February 21, 2010 Report Posted February 21, 2010 21cc domes for pump gas. If your running a keihin carb i would say about a 155-165 main and a 42ish pilot jet Quote
88BANSHEERIDER Posted February 22, 2010 Author Report Posted February 22, 2010 does anyone know about running aviation gas in these things and anyone know what octane they are Quote
88BANSHEERIDER Posted February 26, 2010 Author Report Posted February 26, 2010 i was wondering if i could run 20cc domes on it when rebuilt it last jan the compression ratio after it was broke in was around 135 would 20cc with 93 be ok or would i be on the edge i would love to run turbo blue but need to find a spot that sells it thanks matt Quote
GrMeyer Posted February 26, 2010 Report Posted February 26, 2010 yeah I fun AVgas Run it 100% in two of my build raptors with no probs. I run a 50%50 mix of 100ll and 91pump in my banshee. Have been running it for over three years with no probs. But I like to also run a carb clean every now and then. About a cap full of the stuff in each bike but the banshee. I just rebuild my 660 motor and everything still looked good. I thought the carbon was going to be bad but it was just as clean as when I was running race gas. 20cc domes might put you in the 160's. Off of Noss's website. But you will need to put the domes in for the gas your wanting to run. Quote
