Big brown goodie truck came yesterday with a box from Evans Ward :ups:

Shot some of Walmarts best 1200 degree BBQ paint on the flanges. Thanks to Evans Ward for cleaning them up and for the beautiful pipes! :patriot: :patriot:

Toomeys and flanges removed. Spec2s unpacked and ready. I will be able to reuse the flange gaskets as they are undamaged. I have new flange and cylinder gaskets from Yambits.

I was hoping for the lazy way out being able to install the Spec2s without having to swap the flanges but the Spec2 pipes are considerably larger in diameter everywhere and don't even come close to sliding into the DG flanges (the Toomeys slid right into them). Tomorrow if time permits before work I will finish the install.
Those look familiar. Nice pipes.
Yes they are thanks!

A successful afternoon. Pipes went on without a hitch. They fit perfectly. Chamber condoms work excellent. I need to trim the high temp silicone sealer a bit. Chinese radiator removed. Yamaha factory radiator installed courtesy of Evans Ward :patriot: :patriot:
Filled coolant system and ran it up with my auxiliary fuel tank connected. No leaks noted. Buttoned everything up and took a test ride. I am very happy with the Spec2s. M in SC told me that they would outperform all the others on my ported motor and he was right :righteous: :righteous: I am also pleased to report the heating issues appear to be resolved with the replacement radiator. It was in the 90s here and I flogged it pretty hard for 20 miles. Temperature never went above 185 while moving. I had to turn on the fan in stop and go traffic. I will know for sure when I take it out on the interstate.But I think it is fixed.
Spec II pipes are one of the great pipes of the two stroke era.
I agree!
Mine arrived with coconut water packing :guinness:
That bike and those pipes look great.
I recently purchased a used RD350 with some OG Spec 2's. I'm going deep into the rabbit hole.
I have them fully disassembled, plugged at both ends with something I've concocted to break down some buildup. Going to repack, media blast,paint and polish.
What's your recipe? I've always wondered what to use; where does one buy "caustic soda", as advised by one of the books on my shelf?

I use 1 can of brake clean and 1 gallon of kerosene in each pipe, along with some small nuts and bolts that I have laying around, Plug it up at each end and let it sit for a couple days shaking it frequently. The small parts I soak in an ultrasonic cleaner with degreaser.

Caustic soda is the main ingredient in most drain cleaners. Also called lye.
Carbon tetra-chloride does a great job of cleaning carbon out of pipes, but it is difficult to get these days.
Put 50 miles on it on Friday. 20 on Saturday. Ran hard 80-90 MPH on curvy back roads and temperature ran 185-190. Took it out on the interstate and it had a burble right at the transition trying to hold steady speed 1/8 to 1/4 throttle in 6th 6200-6500 RPM 70-75 MPH. How dare I try to ride it like a normal motorcycle! Above and below that perfect. Air temperature was 80 degrees. Airscrews are 1.0 turns out VM28 RD350 air-cooled carbs. 290 main jets, needles all the way rich. 30 pilots. So I decided it was lean right at the transition and took the pods off and put the Yboot with the big Uni filter on it as I am already as rich as I can go on the needle and already tried 32.5 pilots before and they made it too rich. I took it out again yesterday and it is better but ran worse after it warmed up, which tells me it was rich not lean. So I turned the airscrews in to 3/4 to confirm it was rich and it got worse. Turned the airscrews out to 1.25 and the burble is nearly gone and moved closer to 1/8 throttle at 60-65 MPH and 6000 RPM. Of course the air temperature was 10 degrees warmer so it wasn't an optimum jetting day. Long story short. I am cautiously optimistic that the cooling issue is solved and this burble can be worked out or not as it is very minor. Thanks M in SC for the advice as always.
awesome :celebrate:
