need help with deceleration

[ssincity]

Okay, first off let me say thanks to everyone on the forum. I have gotten many of my questions answered by using the search. But this one I can not find a answer to.

 

I have a shee with a ct racing 370 kit and pwk28's It sat for just about ever (1.5 yr) and then I bought it and I drained the gas pulled the carbs apart and flushed with plenty of carb cleaner.

 

Put fresh mix in and fired right up. Has excellent rev and idle. But it is very very slow to delcelerate/bringing the rmps back to idle once let off the throttle while clutch is in or in neutral.

 

Our other shees are more less stock with just pipes and jet and k&n and they bring the rpms back ti idle/decelerate in neutral very very quick. I mean right back to idle.

 

My 370 seems to take a few just to get back to idle.

 

The Thumb throttle comes all the back just fine and then the motor slows the RPMS.

 

Any one have any ideas?

Check and see if your throttle cable is not stuck on the frame under the gas tank when I put my new carbs on that is what happend and one of the cables got stretched just enough to hold the slide opened a little and also check and make sure you synked the carbs the same.

You could have an air leak in the intake tract. That would cause it to go lean and not let the engine rpm drop very fast. :thumbsup:

^^^^ yep, I'd check for leaks B4 running it to much^^^

Leaks or just plain old too lean jetting. Hanging RPM's are a classic indicator of lean jetting. It could be something in cable as far as fraying and hanging on the sheath, but I'd jet up a couple sizes, see if that helps and then do some plug checks to dial it in.
