so, like, i mean, like
WHAT IS YOUR JETTING?

I shattered many HEMI pistons.
No foreign debris, just bad iggy timing and/or hot exhaust valves(bad seats)

OTOH, I lost a few parts in the intake and did zero damage.

Funny luck.

 

So much for putting it back to stock..........................

Loose or cracked reed?
broken intake skirt?

I thought you were to put it back to stock, or when it ran good then go from there?

Just like dr. house

oh, no nothing like the wirges 'washer'. im very familiar w those.  these,are straight thru. like dencos.

Ok, scratch that.

Thanx!

I am not familiar with Toomey, but do they have internal baffle(s)?

Wirges for Kaw H1's were notorious for breaking baffles and flopping around at different positions at certain RPM's.

This is why I ask.

gotcha

It

has nothing to do w any of that. its a basic rz setup w aftermarket pipes. motor is fresh. it idles perfect and runs up high perfect. this rules out:
crank seals
reeds
air leaks
worn rings
etc.

its all midrange. we verified the pv position and operation. 
it -feels- like carburetor but it did it to me at 1/4 throttle And wide open. it follows rpm only.

rpm specific issues regardless of throttle position point towards electrical. 

as does the fact that it ran fine,  then suddenly just didn't.   after the motorvwas refreshed, and had some mileage on it.

if it was MY bike, id get a set of individual carbs and a splitter type cable to eliminate the stock carbs . and.. honestly,  they work better.

its a us model fwiw.

So why chase carburation?

How about collapsed baffle(s) in aftermarket pipe(s)
Pipes that were good suddenly flat regardless of throttle sounds like pipes out of tune with engine.

i.e. Factory Pipe Product on my H1 has the flatspot at 5-5800rpm regardless of throttle.
They are tuned for 9200. They have zero baffles. Stock exhaust no flatspot.

Time to waste, I am retired.

I have read the whole thing.

I have H1's and a DT250.

I am not privy to the RZ bikes as to how the exhaust is mounted to the Jugs.
Nor am I knowing the exhaust system, is it US or CAN? Paint suggests CAN with zero cats.

Crank seal leak-down done? both left/right and l/r to each other?

Geez, 16 pages of PV or something flatlining the thing.

Maybe I read the whole post and weed out muffler bearings.

I run tubes to keep the tires warmer for better grip.

If you ain't racing, you need heat in the tires.
