Well, cool dad 
Maybe you can change the mains without throwing off the carb synch.
Hope it works noticeably better for you!

I see the red outer covers on your UNI filters and remember having to switch to bigger main jets when I slid them off of the RD400 filters.

Lost some coarse filtration protection but must have gained some top end.

Apples to oranges, though.

Seems like the man purse completes the vibe.

I slipped a gapped lock washer where the cable goes into the throttle housing. Did more than I thought it would. Had to pull in on the adjustment. It's perfect.

Fooling with the air screw and needle now. I might want to visit, Mark.

The tach seems to be reading high, which doesn't help my brain. However, suddenly going wide open at "7k" in 3rd gear is very rewarding.

Thanks!

I'm right at the end on cable adjustment. Lengthened the adjustment at each carb too.

This is a 6mm thread. Maybe there is a ready made product to give me another 1/8" with a slot to slip it in?

I'll check the web for a "standoff" adapter and cut a slot with a cutoff wheel or hacksaw(?)

Still running very well.
Gotta check the iggy and power valve curves and make sure they are what I think they are.

Is this head impractical for the street because it requires special fuel?
Just looking ahead on things and wondering.

agree. imho the only real downside is weight. 

I think they should do a supercharged version of the 400.

The NGK.com plugs came in.
The 4 pc box lid has a serial number debossed on the inside and the box color printing is sharp. "Japan" stamped deep on the metal body and no tool marks on the curved "squeeze" area.

Iridium electrodes are spot on. They are genuine BR9EIX 3981 

mnein?
Listen to that familiar sound at the beginning of the video above.
Makes me feel all warm and fuzzy.

Thank you Mark!

I maxed out the adjustment at the throttle housing to two threads left. It's just enough.

One more shakedown to see if the pilots need to drop down a size.

The metallic thunk when the slides hit bottom is satisfying.

I keep seeing that someone has a Suzuki rotary. Seems like only a brave and dedicated person would be involved in that.

HOWEVER, WHERE did those cool wheels come from on the yellow RD from PA?

I just went to order more BR9EIX plugs and saw them offered at NGK.com.
Ordered (4) and it was a total of $47.40 with the added shipping. Tax didn't show.

That spring is strong and skinny and squirrely. Mikunis are a cake walk. I couldn't make it go that way. Used 90 degree needle nose plus straight needle nose while hands were cramping.
Rode it and the main is close enough at 150. A little burbly down low, so turning out the air screw for the next ride.

Cable is a little too long, so I'll fiddle with it.

Would be nice to have an extension with a split in it.
Hmmm, maybe a clutch cable adjuster?

PWK's are on. Some oil in the lines. Cable finagled out of 2 angled Banshee carb cables that came with the Sudco carbs, oil leg that came with the busted CMSNL cable and the splitter housing tie wrapped tightly so it will stay together normally. Fuel lines run. Waiting on finishing later with the UNIs. Synched up. Not started yet.

I'll probably start it and fill the lines tonight or tomorrow. My hands are worn out. You guys didn't warn me that the PWK slide springs are too much to handle without creative tool usage.

The throttle snap back is amazing though.

Mark, I took your hint and dropped the needle one step. Really hope I don't have to go back in and change it
