How is your cold start?
Mine is pretty bad, it is lean. Shaking and stalling, RPM don't go higher than 1000.
I cleaned cold start tube holes.
Is there jet sitting in bowl? Did you look in the bowl hole for cold start tube?
I didn't clean bowl jet and don't know if it is there.
The diagram shows a jet in bowl.
I will drill tube hole like Swest did, I just want to see if bad cold start is a common problem.
Thanks.

Some carbs have a fuel passage cast into the bowl itself for the choke circuit. If you'rs has one make sure it's clear.

For how long? For one minute? Is your bike on side stand usually?Kidkawie wrote: I do turn on the petcock for a bit so the bowls fill up.

Now its a non issue. But there again im runniing the stock airbox and finally got the jetting and the carbs working well.
if your running the pumpers you want to make sure the check balls, e clips and that the orings are in place on the sprayers.
and make sure the bowls are clean where the enrichener goes.
your in Fla you dont have cold start weather lol
i say you need bigger pilots

Yes about minute. The carbs arent dry the next day, but some fuel evaporates the longer it sits.

and it may open up the door for more problems..
If you havent done it yet you need to COMPLETELY disassemble those carbs .
you bike should not have a cold start issue and either something is still stopped up or your jetting is wrong.
also the float levels play a large part so doing the clear tube method is a must.
when you get them right youll be able to pull that chock lever up, and almost immediately go back down with it.
I made a stand to place my carbs on so i could set the float levels and verify the sprayers are working.

I agree with Steve on the Valve adjust.
But im still leaning (pun intended) on larger pilots.
what sizes are you running now?
