Octane for a mostly stock motor

[side_fxxx]

I just purchased a stock shee and put a T5 pipe kit. I read the manual and it said it only has a 6.5:1 compression ratio that should be good for 87 octane right? I dont have anymore mods because its fast enough right now...

if you do the pipes i would do the filters and re jet it and at least run 93 or 91 whatever you have im in cali so we have 91.

you can, but I always ran 93 anyways stock.

pump gas in the 90's should be fine..

yeah i got the kit with filter and jets....

 

but with a 6.5:1 ratio why you need 90+. most 4 stroke motors are in the 9's plus and run on 87. im only asking with the 3.00 plus prices.

 

and in ohio we have 87 89 93 to choose from with a ten cent difference.

 

also off topic a little but how much trail riding (mostly around idle and some full throttle bursts up hills) to you get mile wise?

I run 87 and I havnt had any probs. Pipes dont have any affect on compression so you will be fine on 87oct gas.

LOL, its not about how long your gas will last... its about how much of a pounding your body can take with stock suspension. ive never burned more than 4 gallons riding a full day of trails. Riding dunes however, i have burned upwards of 8 gallons a day

With my engine I always ran 94. It just ran great on it so that is what I have stuck with. My Brothers 400EX says run Premium gas only.

 

I recently went on a 40 mile ride and did some hill races on a single tank of fuel.
