every since I had a clogged injecter and cleand it out my self
my bike has run strong no miss, but backfires when slowing down and sometimes a little cough when at idol other then that it rides great.
my next thing to do is new plugs, do I need to replace the injecter that was clogged?

Check TPS and for air leaks in the throttle bodies

Easy way to check for air leaks around TBS: Buy a can of starting fuild and spray it around the various rubber bits. If the RPMs chance then you've got a leak.

(You used to be able to use WD-40 but the safety Nazis forced then to later it so that it's now non-flammable.)

Huh, when did this happen? I've always used it for starter fluid.

In the last few years I think. I've got old and new. The new is not flammable - so I save the old stuff for starting fires and burning neighborhood cats. I use the new stuff for lubrication.

No sweat, we all found out the same way. Cracked throttle body rubber?

No one of the rubber stoppers on the throttle body blew off.
I had a replacement and all is good.
