Jetting advise

[glassjawjm]

How's it going, just got some 30mm oko's from a guy right here on hq, they came with 48pilots, and 152 mains.

My mods are as followed

 

chariot one peice, 19cc

+4

vf3

t5's

std. Bore & stroke

Revmax cdi

pods with prefilters

 

I'm at sealevel, with temps mostly in the 70-90, but soon getting cooler(60-70),

I have 180 psi, and a solid engine with no leaks. 40:1 with 70/30 103 octane.

 

I think these jets Are a little lean, the pilots I can get it to richen up, but would rather jump up a size.needles on 1st from bottom with 1 turn out, but I would like tobring that up to may e a 50 and tune back on needle and screw.

 

The main I feel is really lean, just checking the plugs and being close to the engine, I can hear it saying cool me the fuck off. And I barley opened her up maybe wot in 2nd. The I putted around the yard. The plugs were brand new(br8's) and there were no signs or oil left on them, even idle and putting around the yard, there was no oil. So before I get this wide open to do a plug chop, what would be a good rich setting. 52'sp 155'sm??

Also I heard it would we wise to set timing stock for rejetting???

I run the same carbs just diff mods.

 

But i would get rid of the small JJH needles and grab your self some N68A needles.

 

IMO your mains are real small at sea level with the mods you have.

 

So grab your self some 155's, 158's and 160's

 

Stick the 160's in and do a PROPER plug chop and go from there. Might have to go down on the mains from 160 but you wont be able to know this until you try it and do the plug chop not check.

ADVICE!!!!!! Dam kid.......

 

The needles start with "n", I'm not sure the rest Ill have to check when I get home. How do the pilots sound, do ya think one up would solve? I'm going to grab a bunch jets just wondering the range I should grab. Thanks

How do you like your Carbs??? My float valves has been bored out to 1.25 instead of the stock .75 to keep the fuel Up to speed , I heard this was a common problem, any other problems you have run into, also I don't like he stock size pods fitment, I don't like how there so stretched, what are you running for filters?
