the right stuff

[b4e2r0t]

just wanted to get a couple cents from some people in the banshee community. ive been reading alot of other threads about some of my issues and have learned alot thanks to you all.

 

i dont no much about rebuilding stuff so here it goes. me and a friend (that knows engines) just rebuilt my motor on my 01 shee with wiesco prolites 75 over. i have 18cc domes in the coolhead, i bought this bike with the 18cc domes in it. the thing ran like a raped ape when i first got it but didnt run the right fule in it and had pre detination witch led to smear (sunoco 94). i can buy sunoco 116 octane right around the corner from me for $7.19 a gallon. will i be alright with this octane? i can get cam2 witch is 100 octane also for $5.25 a gallon. i live in the philadelphia area of pennsylvania, not quite sure of the elevation. now i do alot of riding in the pocono mountain regin witch is only about a 1500ft increase in elevation i believe, the bikes always run better up there with the thinner air.

 

other mods to the bike that might help are cpi inframes, vitos reed cage and reeds, reed spacers, cpw keihin carbs main jets are 150, needle clip 3rd notch, and the compression im getting when kicking it over is roughly 200-235 (beforing running it) i havent checked pressure since broken in (dont no how much it would change) i barrowed some of my budys 112 octane that he runs in his worked raptor just to break the shee in. problem is 112 we can only find on the net and its like $60 for 5 gallons plus SH.

 

whatever info anyone could give me would be fantastic since i am going on a trip upstate this weekend and want to have an idea on the right fule octane.

 

p.s. also what ratio should i mix my oil at? i run klotz. i was thinking 40:1.

What 200-235 thats a big diffirence.I would ckeck the gauge.Ar you running stk stroke?Both of those numbers are really high.I run 18cc domes on a fresh bore and get 185-190.I run 111octane you might ckeck around at some race shops i buy mine for $5 a gallon if i get 55 at the time.As for your compression iwould try a diffirernt tester to be sure and if its that high i would go to about a 20cc domeI personaly dont like anything above 180 for gas and ive never ran anything else so i couldnt tell you about what they run on alky.If you noticed a difference in power by going up in elavation your proably running lean at lower elevation,you should make more power lower because there is more oxygen in the air.

I don't see where you mentioned the timing you are running. 18cc domes are pretty tight, and if you are also running bumped timing, the elevation changes could cause detonation problems and real jetting headaches no matter what the octane is. Some bigger displacement domes will keep your bike running better for longer, with just a little loss in bottom end, allowing well advanced timing with better jetting stability.

P.S. 40:1 is a pretty good ratio for Klotz, I run it at 50:1 at sea level.

thanks for the info guys.

 

i will look into a different gauge for the compression testing.

 

it is a stock stroke.

 

its got some porting work.

 

as for the timing i dont no what it is yet and have been trying to find the time to check it with my friend befor this riding trip. anyone know where abouts i should be with the timing so when i check it i can adjust it accordingly?

 

i have one more place i can check for a lower octane, ill look for some 112 there. if not i think im gonna try the 116.
