Your main is too small

[sheerider11]

Your pilot is to small, and your needle probably as well. And your main.

Is your motor ported for the 4 mil too?

[joshua_n92]

i did not ported the motor and the needle is in the 3 rd ( middle) ,whitch pilot and main you think i should go for

You should get your motor set up for the 4mil before even thinking about jetting. You could have it dialed in perfect, but without porting for that crank it won't run well. If you have some sweet cast stroker pistons, all circuits are lean.

I just put 30 pilots in a stock motor with pipes and it's pretty crisp. That thing of yours should be a mess to ride. Surprised it hasn't melted down yet.

your motor hates you. if you don't stop riding it and learn how to jet the hell out of that thing i GUARENTEE you will be rebuilding that bike all over again.  It doesn't take much....especially when your doing a wide open run, if they're jetted lean....and a decent amount like yours, they'll melt down in minutes.

thnx a lot i will go and ported my motor thene i just rebuilt it a few months ago .. whene she done i'm letting yal know

[joshua_n92]

my motor is done i had everything cleaned she start perfect and idel perfect i let it idel for 10 to 15 min thene turn it off let it cooldown thene let it idel for another 15 min thene take it for a slow ride like 20 to 25 min everything is good now its time for rev it up she will rev up but the rev wasn't clean she like choking or something

[Jereme6655]

your jets.  FFS......change your jets......not to mention they were already small, but now its starting to get colder out (depending where you are) 

 

Im telling you......shut it down and get on the jetting thing....at least get in the ball park......or your going to lock your motor up.

Wow! So trying to make sense of what you said, your intake boots are cracked? So you replaced them and now it acts even richer? Did I understand right?

Do you have the hose between both carbs hooked up and tight (choke hose)?
