heres what happens when i hit the gas...

theres a hesitation to go. to accelerate. sometimes when the light turns green Ill let let the clutch out and it will chug....so I have to brining the clutch back in and wait for the revs to climb. Has almost got me rear-ended not to mention makes me look like an idiot. I cant tell if it's feels like a fuel flow problem or something vacuum related. The problem seems to get better as the bike warms up but never completely goes away.

Thoughts?

at what RPM are you launching? If it's below 5.5K, you just need to rev higher and slip the clutch more.

Hang out there, we may flame, but we don't hate.

My attitude is in serious need of readjustment, and I'm ok with that.

rejet if you haven't already.  Check your valve clearance if your bike seems like it's taking forever to warm up.  Out of spec valves make the bike run like a turd.  Check the valves before the rejet.

A little more info would help. I pretty much have the same problem after rejetting with a stock exhaust and K&N drop in filter. I'm gonna try raising the float height a little bit when I get time.

Here's a test to see if your carburetion is lean:

After a 10-15 minute ride, put it in neutral, let it idle for a few seconds, grab the throttle and give it a good hard, fast twist, and then let go.  If it stalls, it's too lean.  If it comes down slow, it's lean.

When I do that..it typically drops rpms, almost to the point of stalling, then climbs.

I had to click on your profile and list all of your posts to read that you have a V&H pipe.

If it has been rejetted, I'm going to go with slightly rich on the bottom.  After, that...

How many miles since your last valve adjustment?

I'm running Prime. Seems a lil better.Gonna go ride a little more.

Dunno when the valves were last touched.

Suzuk-E

Yeah. Definitely some kind of carb problem.


Got links to any good how-to's on carb removal/cleaning?

It sure does. Thanks.


Question: The Prime setting on the petcock bypasses the RES setting, correct? I mean, if you run out of gas on Prime...you're totally OUT of gas.

Jarrett

If you run out of fuel in prime, you are completely out of fuel.
