Toomey T5 rubber joint is smoking

[bksdesign]

I have an 02 Banshee with toomey pipes and K&N filters on it. It is jetted with 280s and 25 pilots. I just bought it and it had a twist throttle. I just changed it to a thumb throttle, and resynced the carbs. A couple times when it was parked with the gas on it would leak fuel from the overflow tube, so while it was apart I raised the floats to 21mm. I also checked the airscrews and they were 1 and a 1/4 out so I set them to 11/2 out.

 

Now here is my questiion, I just test road it and its running real good, but when I parked it there was a small amount of smoke coming from the black hoses in the middle of the tommey T5 exaust. Not smoke like leaking, smoke like its very hot. I also noticed it was a little harder to start, it started and died a couple times before it started running good.

 

Are the toomeys suppose to have black hose in the middle under the seat? Has anyone had it smoke like that before. I am scared its running lean due to my tinkering on it, because its running real good. Also I changed the angled air jet thats on the air fliter side of the carbs from 11/4 turns to 11/2 turns out because thats the setting on the toomey site. did that lean it out? Please help I do not want to blow it up.

 

Thanks

bk....welcome to the HQ buddy. Well.....its simple to find out if your running lean or not. What you need to do is a plug-chop. Warm your bike up with the current plugs in it......then shut it off and put in BRAND NEW plugs......fire it up and immediately do a full throttle run to the top of 6th gear. Then as soon as you hit the top of 6th.....pull the clutch in and shut the motor off and coast to a stop. pull out your test plugs and reinstall your old plugs and ride home.......then cut the threads off of the test plugs....

 

if its running correct it should be a milk choclaty color.......like a medium brown. if its a tan color its running too lean......if its a dark brown its running too rich. That's how you check if a 2stroke is jetted correctly.

 

since you also have an aftermarket exhaust......id suggest rejetting the pilot jets to a 27.5 this way they flow a little more fuel at idle and it will also help with start-up
