milo_32000 Posted October 11, 2006 Report Share Posted October 11, 2006 How much can be milled from a stock head and still use 92 octane gas ? I think I saw somewhere it was .030, I don`t want to end up having to buy race fuel, Thanks for ya`ll help, Milo_32000 Quote Link to comment Share on other sites More sharing options...
dajogejr Posted October 11, 2006 Report Share Posted October 11, 2006 Need some more info. Are you/do you plan on advancing the timing? What altitude do you ride at? Compression has more to do with the need for race gas than timing, unless you advance it ALOT... Every 1000ft of elevation is ROUGHLY 5 to 15PSI drop in pressure...again, ROUGHLY....

milo_32000 Posted October 11, 2006 Author Report Share Posted October 11, 2006 My elevation is 139 feet above sea level, no advance on timing, everything is stock execpt pipes, Thanks for responding, Milo_32000 Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted October 11, 2006 Report Share Posted October 11, 2006 running a stock moter at sea level (what your at pretty much) i think .030 will be too much to run 92 octane. any reason you dont want to run 50/50 or maybe 100?

dajogejr Posted October 11, 2006 Report Share Posted October 11, 2006 I would go .020 and +4 on an advanced timing plate. I THINK that would be safe for pump gas. Worse comes to worse, you can always back the timing off (benefit of an adjustable plate vs. a key). You will get noticeable bottom end and 'response" from those two cheap and easy mods. I'm still a big fan of a lightened flywheel, as well.... Quote Link to comment Share on other sites More sharing options...

dajogejr Posted October 11, 2006 Report Share Posted October 11, 2006 Different strokes for different folks... When I put my lightened flywheel and +4 advance on, it was EASIER to ride and keep on the pipe in trails. Bone stock motor, Pods and T5 pipes, and I never milled my head. Coming off the line, coming out of turns...I could lug it like a 4 poke, hit the throttle and the power was there right now.... I actually liked the flywheel lightened better for trails more than anything!!! My buddy with a pretty done up 450R rode my shee before an after and said the exact same thing...it's almost 4 stroke like in trails (which, is a good thing).... It did idle about 300 RPM lower...which, could've been weather, etc....but, once I turned up the idle just a hair, I LOVED IT..... And, actually....many will tell you if you're a heavier rider, as I am (husky 240lbs...) a shaved flywheel is not a good idea for drag racing, it takes away from your holeshot inertia.... I've yet to run a lightened flywheel on my cub motor....but, I'm going to get it done. Worse comes to worse, it's 125.00 for a brand new Ricky Stator flywhell...so not like I'd be loosing a ton of cash, and I'm pretty sure I could get most of that back by selling my flywheel once it's shave should I not like it. It's only 5 months old...and yes, it was a brand new RS Flywheel..... Quote Link to comment Share on other sites More sharing options...

2004LEBanshee Posted October 14, 2006 Report Share Posted October 14, 2006 Pm me if you want a already milled head. It was done by Boonman from this site. Did a great job milled .030 over. Domes are perfect not a knick. Off a 04 banshee. Made a big difference with the lightened flywheel and timing. Great mod. Quote Link to comment Share on other sites More sharing options...
