2003LimitedBanshee Posted January 15, 2006 Report Posted January 15, 2006 should I just try and search then? lol 459818[/snapback] I would try a search. I am surprised that no one has responded. I saw the post, but have never jetted a bike with these pipes. I will try and give it my best shot, as it will probably get you in the ballpark. When you say 2:1 intake, do you mean you are running 1 carb feeding both cylinders, or do you mean you are running a single filter element for both carbs, with the airbox eliminated? If you are running the latter, with the stock Mikunis, I would guess that you should be in the 340 range. I say this because as I understand the Shearer's are a slightly more top end pipe. Now, most classify the T5's I run as more top end as well. Thus, I am running 340's with the mods listed in my sig (when I run at sea level approx 65 degrees), and the only differences are the timing advance (I went up 1 size) and the VForce's (no change for me). So I would guess you would be around the same jetting specs. Notice I said around, the Shearer's may flow a little bit better up top and so you may even end up a size (probably not 2 though) above that. In case you didn't know, the old standby ballpark jetting is to go up until it will not clean out in 6th gear, then go back down one size. You should also do a WOT plug color check to confirm your jetting. Quote
Ls7colorado Posted January 15, 2006 Author Report Posted January 15, 2006 ok cool, I just needed a ballpark guesstimate. I was talkin about the tommey 2-in-1 filter element with air box eleminated. I guess ill start at 340 then, and yes I still have stock carbs, thanks any more info would be great! Quote
NEVER SATISFIED Posted January 16, 2006 Report Posted January 16, 2006 got any port work.... what airfilter... Quote
Old Two-Smoke Posted January 16, 2006 Report Posted January 16, 2006 Are you sure your at 500ft most of Colorado is a bit higher than that. I am at 4000 ft here in Nv. I have t5s and the the uni-filter +4 timming and I run 260 summer and 290 winter. I also run different oil ratio's winter to summer. Quote
Ls7colorado Posted January 17, 2006 Author Report Posted January 17, 2006 Stock port, uni filter.... I live in TN, I drive a colorado. hehe its right aroun 500 ft at the drag strip here Quote
2003LimitedBanshee Posted January 17, 2006 Report Posted January 17, 2006 Stock port, uni filter....

slowpokebanshee Posted January 17, 2006 Report Posted January 17, 2006 ls7 colorado? knowing a little something about chevrolet.....tell me it's true you have a colorado w/ls7 in it? or just dreaming.... Quote
NEVER SATISFIED Posted January 17, 2006 Report Posted January 17, 2006 go up 14 sizes from stock on the mains 1-2 sizes on the pilot keep needle stock loacation adjust airscrew if necc.... do a WOT if it cuts out at full throttle and feels like it wont pull no more go up again on the mains... if it bogs go down.

Ls7colorado Posted January 17, 2006 Author Report Posted January 17, 2006 ok ill try that, so the mains are mostly for higher RPMS...? slowpokebanshee, I dont have a LS7 "YET......." Quote
Banchetta Posted January 17, 2006 Report Posted January 17, 2006 The mains are for full throttle, not to be confused w/ high rpms...Put some 340-350 mains in there, run it wide open in 6th gear for 5-10 seconds, kill it, coast to a stop, pull the plugs....black is rich, brown is perfect, tan is lean. Look at the tip of the plug. Quote
Ls7colorado Posted January 18, 2006 Author Report Posted January 18, 2006 so a WOT run iss all that is needed. Sounds pretty simple.... Quote
s-540 Posted January 18, 2006 Report Posted January 18, 2006 ok ill try that, so the mains are mostly for higher RPMS...? slowpokebanshee, I dont have a LS7 "YET......." 460931[/snapback] put a ZL1 in it. Quote
