superchicken Posted October 24, 2004 Report Posted October 24, 2004 what evelation are you at?ya need to know that in order to figure your compression with different domes read here try to stay around 160psi with pump gas Quote
banshee76179 Posted October 25, 2004 Report Posted October 25, 2004 155-160 is the cut off for 93 octane... I would say around 20cc or 21cc depends on ur elev. Quote
sandornothing Posted October 25, 2004 Report Posted October 25, 2004 Here is what you can do to safely run 20cc domes on pump gas. Get 2 inline coolers off ebay, theyre dirt ass cheap. Flush your rad and fill it with Engine Ice. All of this, and the added cooling of the aluminum head allows me to run 20cc domes on 91 octane at 32:1 with no adverse effects. Good choice on the Noss head, if im correct they use the stock studs. The stock studs are a bitch to take out. If I would have gone that route i wouldve had it done and running in 20 minutes. Also dial in your jetting if it isnt already. A lean motor is a hot motor, and hot motors have a tendancy to detonate (ping) easier. If youve got 93 octane where youre at yourre definately OK. By the way, 20cc domes only gave me 160 psi on a MAC compression tester. Its a good cheap combo that wont jail rape you when it comes time to buy gas , go for it. Oh, and Glamis was the shit this weekend, see you guys there next weekend maybe! Quote
Leadfoot350 Posted October 25, 2004 Report Posted October 25, 2004 I was there. Sand was a little wet but it was a great first time back. My bike stoped firing the right cylinder and I could not figure out why even when i took it apart today. Quote
sandornothing Posted October 25, 2004 Report Posted October 25, 2004 yeah it was a little wet and choppy around gecko and hooker point from those damn 600HP rails digging trenches everywhere, but if you get way back in the dunes between olds and the camp their was alot damp virgin dunes everywhere. My 21 inch geckos felt like they where glued to the sand. As soon as i got it in the pipes, the front end was up at a 45. Anyway im hoarding this dudes "dome" post. Post guy, drop a question about the setup if youve got one. I'll try my best to help. Quote
