hard to start when warm?

[donkeypuncher]

alright, so i finally got to take my bike out for some real ridin since i pickid up the 33 pwk's and i have a couple of minor problems i need help with. 1st, when i start my bike up cold it takes only 2 or 3 kicks with the choke out and no throttle to get started but when my bikes warm, it takes atleast 3 or 4 kicks with half throttle to get runnin? with my stock carbs on it took one soft ass kick to fire it up when warm, wtf? 2nd, the bottom end is really lacking in pretty much every gear, i cant launch in second gear without it takin a second to pick up and go. so with that said, it must be my pilot jet or needle setting right?

 

right now i'm runnin 155 mains, 50 pilots and cel needle on 3rd clip. any ideas as to what to change? am i rich or lean you think?

 

mods are : t5's, vf3's, 33mm pwk's, 21cc domes, +5 timing, pod filters and herr juggs dune port.

 

thanks for the help fellas!

will it start with the choke warm, or without the choke cold? try the needle in different positions(start by going a clip richer) and play with different airscrew settings, but remember to adjust the airscrews when it's completely warmmed up, or they will be off. what do the plugs look like after it's been run a while?

sounds like the pilot circuit is a bit rich. maybe lean out the pilot jet 1 size and/or open the air screws a tad. maybe the 33's are a little too big for your motor work, and they are taking away too much off the bottom?

Your rich off the bottom, or you have a weak link in the electrical system.

 

Turn your air screws out .5 then 1.0 turns and see if that helps.

If not, go one size smaller on the pilots as said.

 

An HJR dune port with those mods will pull 33's strong all day long.

never tried with choke warm or without choke cold( pretty much always start it with choke pulled out). after a WOT run the plugs were wet, i'm thinkin the main is a little rich too but my main concern is the bottom end. havent done a plug chop yet though.

kevin (hjr) suggested 33's when i asked what carbs would work best with the port work. im sure this isn't the problem.

sounds good, ill try the air screw first then try out the pilot jets and see what heppens.

if it is the electrical system any ideas as to what or where the problem is located?

 

thanks again for the helpfull suggestions guys. tryin to get this thing dialed in before summer hits.

whoops, i over looked that you had a dune port. i thought your were OEM port. sorry about that. i got to stop reading the questions soo fast....LOL. :biggrin: the thing that sets off a red flag that your pilot circuit is rich, is how you need to crack the throttle a little, which is adding enough air to the mix to start the bike and making what rich pilot settings would be with the throttle slides all the way down, just about gone, cause your throttle slides are up a bit....giving you that more air. just back out the air screws a bit and/or back down the pilots 1 size, like already suggested.
