First time I've taken the RZ more than around the block. I did a deep dive on the carbs over winter. Has a K&N tall filter with a 2 into 1. Premix. Unknown brand aftermarket battery less ignition. Unsure what stock yamaha ignition parts are on it. This is an Ex WERA bike, has some port work done with initials on the cylinders. Never been into the motor. Iridium plugs 9's.

Starts kinda hard, needs 1/4 throttle to start (probably cause only left cylinder is starting). Right cylinder only runs above 6k. When revving it's always there and runs like a top. Did a power stand up the on ramp today to the highway. But around town that right cylinder drops if you get below 6. Please give me your thoughts. Not looking for clean the carbs comments. I know I'll probably end up doing it again. I am very well versed in aircooled RD's but have no experience with powervalves.

Stock carbs:
2.0 slide
needle clip is third down from the top
Needle is 5K1
Pilot 25
Main 430
Emulsion 0-8 357

To do: Swap plug leads to see if it follows, see what ignition is on it, maybe see if I can install a battery and see if the powervalves cycle before I start it?

I own a factory suzuki  Hop Up Pipe for this bike.... It needs  a new home!

Care to share the homebrew formula and setup? I really need to get a power supply and go to town. Did you put the levers in a vibrator with sand media before hand?

I got scammed on ebay recently. Sent out some H2 coils and the guy started a refund before they even arrived. Then he shipped me back these busted up coils. I tried to tell ebay they weren't the same the caps weren't even NGK. They issued us both a refund so he essentially got the coils for free.

Economy cycle sells emgo direct replacements for like $35

Scott unfortunately is not taking anymore work due to quickly advancing Alzheimers.

We will NOT speak of the mess the swingarms are

What's the deal on them?

I have a hop up pipe for that! It needs sold

I'll be there with some small yamaha twins for sale, let me know if anyone needs RD/R5 parts

My favorite paint job EVER. It's up there with the KR RZ and the green DS6C. I have two of these Mark, ones going to be on the chopping block once I get it cleaned up.

I backed out at 1300. Figured it might take awhile to sell. Its not listed in Medina Ohio for $3500.

 I would do some math on the entire stack. Assume every friction and steel is at the max spec. Figure out the max stack size. Do the same for the min. Does you stack fit inside those parameters?

Ask Mike Krenzelak on FB. He's big into those

I keep looking at this and thinking it might work. Anyone have experience with a TZR125 non-vacuum petcock bolting right in?

If there's half a chance, I might try it out.

I'll pull it off and go take some measurements. Now that I think about it. My petcock doesn't have a vacuum line connected. Maybe it's already been modified or maybe the PO didn't know what they were doing.... The PO wasn't the guy who raced it.
