Alright so ive posted that ive changed my bushings in both clutches, now with everything back together my primary makes a popping noise. Upon inspection (hood up, trackstand, no clutch cover) this noise is made when you hit the gas then let off and once the rpms fall to 3500 the clutch disengages completely and quickly(very quickly), making this smaking/popping noise. I took the clutch back apart no signs of damage or anything catching, cleaned it, put it back together same darn thing.
My sled has a cudney kit, engages at 4500 rpm and shifts out to 8000rpm, this problem wasnt there before i got my hands in those clutches so........
Any ideas?
-any help from anybody is appreciated.
thanks.

Is the belt on? if so sounds to me that you have a nice clean smooth operating clutch that is reacting quickly, and all my be ok take her out and give her run and see how it sounds after a little ride.

Wow, i hope your right. Ya the belt is on...i put about 80km on it the other day and it was still doing it, took it apart last night, nothing looks wrong with it put it back together same thing.

Well I can tell you we have tried to change bushings in the primary a lot of times and most don't work, the poping noise you are probably hearing is when the clutch finally disengages and that is usually caused either by the spring cup bushing or the moveable face bushing especially if you have installed new bushings in either or both parts. -- Bill

the bushings i changed are the small ones at the base of the 3 swinging arms were that allen bolt goes through because they were worn (2per arm). So is this noise normal then?

No. 5 in the picture (bottom left)

When you take your clutch off and hold it up side down do all the arms swing free?? How about your clickers all of them set to the same #? What about the arms comming in contact with the inside of the clutch where the spring is kept. By installing new bushing it might have pushed those arms out a little and they could be hitting the inside of the clutch.

Everything seems to be swinging freely, i thought it may be the cotter pins on the adjustable wieghts catching (although it never happened before i took the clutch apart?) so i took it back apart made sure everything was free and even lightly filed the cotter pins to make sure...didnt help.
-keep the suggestions coming

TTT for ya!

OK, heres the news.....drove it over to the mechanics yesterday, and he said its normal. Told me that its just the roller popping over the "bump" on the ramps in my primary to disengage. He said that its just happening because they'res no play in the bushings anymore so is a bit harder(for lack of a better term) for the rollers to pop over the bump.
Since then I've put on about 220kms, and everything seems ok, he says it may go away after the bushings wear some.
-Thanks for the help everyone, much appreciated!!!!!

O ya, just want to put in a good word for Bill's clutch kit.......had it in for almost 2 years now and it absolutely rocks.

Check that you have the 3 cotter pins on the same side and the shaft on the fixed side is clean and smooth . Sounds like it mite be hanging a little bit.

I agree with Bill's comment.

The noise is because you have a stronger spring (higher engagement) and when the RPM's drop off the spring force will soon exceed the centrifigual force created by rotating the arms & weights. At this point - POP. Not a problem. Every clutch I've had since 1993 did this when you set-up for a more agressive shift.

have you checked you chain tension, maybe you are looking on the wrong side.....

with big primary springs...the TRA will "POP" when it fully dis-engages...NORMAL...BJ
