You should avoide runing to 11000 rpm at all cost.You may get lucky but you could very easily hit a pison with a valve.I did. allthough i do have larger valves and cams.no clacking, running webcams 0.395 at lobes of 104,5 en 108. Gives VERY much torque from 2500-5000rpm. No kick at 9000rpm but will rev 11.000rpm
what year/model, was your bike? What carbs?
what size is your baffle,and what pipe are u running?
You said u have pinging in the mid range. what rpm?
do u know how many psi compresion u have?

It runs good though. I wont worry about it anymore this year. The cold weather is leaning it out a bit too. My new float needle seats are still leaking a bit. I jut got a new petcock to try and a new sealed tank.
its suposed to be nice out tomorrow . My clutch has been sticking, so i will drain the oil , check my clutch plates and, grease the actuator.

Not sure about the sticking clutch - is the cable and actuator adjusted properly? Is it dragging when you have the lever pulled in? Or do you mean the lever action is sticky, not smoothe?

What size did u say your baffle was? u could try removeing it just to see how it affects the clacking.i think the baffle size is a big factor here.

It just started to stick uppon releasing the clutch lever.

I forget the baffle size - maybe 1.25"?? - it's the V&H racing version for the megaphone exhausts. I recently drilled some holes internally to increase flow but haven't had a chance to try it yet. Maybe that will make a difference.
So the clutch isn't engaging when you release the lever? It's slipping?

the baffle does make a difference and the racing baffle is a good choice. I also agree with Mark, try running with no baffle just to see what happens.the baffle...it's the V&H racing version for the megaphone exhausts.
Have you ported your head? Opening up your intake ports will also make a difference. Bigger intake ports will tend to produce more clacking. Your carbs/engine will not respond too well while the carbs are clacking and the results of switching to a different type of carburettor to get better performance are debatable.

Out of curiosity, have you done any porting on this head? If so, what was done? Also, what exhaust are you running? thanks.

Does the popping and flame shooting usually indicate a lean condition?

not a lean condition. that would be popping out the intake.Does the popping and flame shooting usually indicate a lean condition?
Sounds like the #1 cylinder isn't firing. Raw fuel is then sent into the exhaust and burned there (ie popping and flames) remove the #1 spark plug. If the porcelin is wet or black, replace it. If not, connect the plug`wire, ground the plug against the block and turn the engine over to see if you have spark.
While you're at it, you might want to pull all the plugs to check their condition.
Definitely do this before you start messing around with any carb adjustments. Also, unlike most other carbs, the RS34s only need a small amount of mixture screw adjustment. start with 1/4 open and don't go past 1/2 turn.

Thanks for the tip - that makes sense. I did pull the plugs before I started it and they actually looked pretty good. I pulled #1 after I noticed the pipe wasn't very hot and it was black and wet. I haven't had a chance to check for spark yet, but that will be next. I'll probably change all 4 plugs and try again. I'll also reset my mixture screws to about 1/4 before starting. Maybe it's just a fouled plug?? I hope that's it. Thanks again!
