I would appreciate some help quickly

[Sassa Massa]

well guys and gals I got some ported cylinders from somebody who claims that with the right set up (inframe drag pipes and big carbs) i should get close to 85 horses at the crank (i don't know what the port job is considered). well here's my problem.......I've been after this guy about jetting and for some reason he's not helping me out, period. so here I am with an engine that I don't dare to start because I have no idea where to start with the jetting..............needless to say I'm gettin slightly fed up with the service.......ok so I'm really pissed about it. anyway........I don't have big carbs and I don't have inframes, so I need a rough idea of where to start. here's what I've got.......

 

the ported cylinders

fmf fatties

stock carbs with the TORS removal stuff

boyeson 2 stage reeds

shaved head

advanced timing

and no airbox lid

 

If you guys could help me out, you'd be my heroes...........seriously..........i'm getting anxious to try this thing out since it's been apart for 2 months and I don't want to cook it on the first trip out

 

thanks

well there's a couple things that you didn't specify, that would be good to know....how much of timing advance? how much shaved off the head? what's your riding elevation? what are your riding temps? what kind of port job.....mx, trail/woods, drag, dune, what? here's what you could try starting off with, (giving an estimate, cause i don't know your elevation/temps)....here ya go, try 360 to 380 mains, stock needles in stock position, 27.5 pilots, and 1-1/2 turns on air screws.

I honestly don't know what kind of port job it is.........all I Know is with drag pipes and big carbs it's supposed to be capable of 85 ponies. My timing is advanced 4 degrees, 30 thou off the head, i'm not much above sea level and in the summer it is anywhere from 80-90 degrees

360 to 380 will almost certainly be too rich, but it won't hurt to start there. When I ran fatty's they liked a little more fuel in the mid range so I would lower the clip one notch, and 27.5 is where I would start as well on the pilots. Airscrews 1 turn out and go from there.

i'm figuring that, but i just wanted to start fat/safe, and let him work his way down :smile:
