HELP! Buell dies at idle and lack of power in high rpms

Given the recent events for other, it might be worth opening up and inspecting the valve train as well

ok so this weekend i took off the throttle bodies and cleaned them, clean the iac, replaced the spark plugs.... Now i have no backfire coming out exhaust. I havnt rode it yet just fired it up at idle but i will be riding it to work (only form of transportation) so we will see how it does at stops, but its definitely improved a portion of the problems

Soooo.... About that last post, it turns out it sounds better while idling (until it dies) however there is much more popping while decelerating but I believe that may be because of the cheap plugs I was forced to get since no shop and the ngk in stock and the bike was already torn down. I will be ordering the ngk and installing them next weekend and see what happens. I should be getting my spy cable I ordered and will see what I'm capable of doing with it on ecmspy and tuner pro.

Doubt its your spark plugs.

Well this sounds vaguely similar to my current issue. I may have to keep an eye of this one to see if anything arises out of this end.

@Crash well it also has hesitation now in lower rpms and it hasn't done that until I put these cheap ass plugs in. They are called EEE (E3). They are a new brand that just came out, they even looked iffy to me.

Its safe insurance to put better quality plugs something known to work. While its rotated down for plugs pull the valve covers inspect vavles shim coukda been spit out

 

[lively13]

The way I pull the plugs you don't need to rotate the engine...makes the job a lot easier.

I guess you could throw parts at it? You could clean them too.

Post up if it works, if not we'll try to help you diagnose it further.
