carb setup????

[Blaster200boy]

Here is what i have:
Toomey B1 Pipe and silencer
Stock 26mm mikuni carb.
320 main jet
stock pilot jet
stock needle clip position.


What should i adjust the needle and pilot to?
I was thinking about bumping my pilot to a 35?
What about the needle?

i ran the same setup never touched the needle or the pilot and i was running a 340 main with all my mods

 

[yb200]

you should be good to go with the 320 put it in and do a plug chop

For real? I was thinking just bumping the pilot jet to a 35...... and richen the needle by 1... My pipe bogs so would that mean i need to bump my main up to a 330?

 

[yb200]

do you have the lid off?? and is you injection blocked off?? if so id bump up the main 1 or 2 jets

Yep, lid removed, running 32:1. Bog is at 1/4 throttle and also between 3/4 and WOT. Mid is a TAD boggish.

do a plug chop???????????

 

[yb200]

try adjusting the air/fuel screw for the off idle bog...1.5 - 2 turns out from full in and try a 330 and 340 main for the mid to top bog

is your motor rebuilt yet? if not are you saying the bog was before it blew up, this could be caused by low low compression, you had 89 psi right? you would have no power.

damnit, i knew i should of ordered the 340 jet.... I have a 330 main. So change the main to a 330 or 340 for mid to top bog. and adjust a/f screw for off idle bog. i still have to get my cylinder bored and honed. let me go snap a pic of the cylinder and piston....

Yeah i just pulled the head top end apart and gonna get it bored and honed tomorrow...

 

[Blaster200boy]

Here is a couple of pics that i snapped.
Piston look pretty wore out. Rings are seized, what do you think happened? Lean on oil/fuel mixture?

Bore doesn't look like much, but believe me, there is a scar down the side of it.

Intake side of piston....

Exhaust Side of Piston.....

Up above the right hand intake port there are two gouges in the cylinder.

Please tell me what exactly what went on. low on oil mixture?
Lean Jetting?
Just tell me guys!!!
