gas question

[T_Shee]

i recently got my quad and it has a +7 degree timing key. i no a lot of you are gonna say these are junk and im gonna do away with it within the next week or so. but i have rode it qute a bit and it runs really strong and im extremely happy with it. i wanna take it out this weekend proly for the last time of the year. my question is what gas should i run. ive beren running 94 octane and it seems to be fine but could mix in some 110 if you think i should. it has t5 pipes, pwk 35's bored .080 with stock stroke and port. i ride in central IN (not sure of elevation). also im jetted a little rich to be safe. i run repsol oil at 40:1. i measured my compression last night and im at 137 and 140psi. i had my head cut to make my squish .045". let me know what you guys think...i just dont wanna risk hurting anything if my octane isnt high enough.

anybody????

you deffinatly need higher octane for 7degrees and that is way overkill. get a plate and set it for 4 for premium pump gas and higher if you want,

Not sure about +7 timing and your compression with pump gas...but why do you have 35 mm pwks and a stock port motor? Your killing the potential of the motor with carbs with big. You don't have enough intake velocity for those.

 

Or do you mean a 2 into 1 35 mm PWK..that would make more sense.

yeah i hear ya there. it isnt the 2 into 1 setup either. i bought the quad that way thats why its like that. i am currentyl talking to another member about swapping for some smaller carbs. i understand what your saying but this thing runs really good as it is. ive only had it a couple months so its still a work in progress but im gonna ride it as i make improvements. if you think thats bad youd really like the boost bottle and reed spacers i already got rid of. the guy that had it before liked overkill i guess

Yeah for +7 timing you should run a higher octane, but as far as everything else... yeah sounds like he did like over kill. he has T-5's and bored it and is running +7 timing and 35's? Apparently he didn't know what he was doing

I didnt know they made a 7 degree woodruff key?

yeah the guy was pretty much a jerkoff but i wanted a banshee so i went for it. he told me the key was +7 then i checked the receipts he gave me and sure enough it is. anyway you think im better off to go back to stock timing before i ride again since i dont think ill be able to get any 110 before then? i know the mods sound like overkill but i am really shocked at how good this thing runs. it does lack a tad of bottom end but not as bad as you might think, then on top it really runs out good.

well see thers the thing, the +7 timing should feel like a 4 poke on bottom, with stock motor. but that with 35's on a stock moto makes no sence what so ever. the big carbs will KILL your bottom, soo if you are looking for some more bottom get some smaller carbs and get a timing plate .

 

what kind of ridint are you going to be doing mostly.
