That's different.  Is it a street bike ie is there a headlamp hiding under the front plate?

you can probably dump that baking tray oil containment device and mold a simple dam at the rear of the fairing to comply with the rules.

Did you would out why it destroyed a big end? that's unusual - not unheard off, but not common. were the big end feed holes blocked or did you have a pump problem or was it an older crank and the big end was ready to go?

Sorry it took so long, I have been racing the wheels off the RD350, went to Mid Ohio this year, and it was running well! Speaking of wheels, the forks and front wheel are off of a Yamaha Vision 550, and the rear Is off of a 1982 Yamaha Seca 400, the only chain drive bike that has the matching windmill spokes that match the Vision.  I have since put a CB500T tank on it, and ProFlo chambers on it. I will post some pics of it at this year and one from last year!
No headlight, but I built it to be street legal at first, so it had everything. Right now it is strictly race with a Hitachi rotor and pickups, CDI unit from a TZ350, and the box is from a fellow who makes stuff for vintage snowmobiles in Michigan.
The catch pan is some sheetmetal that I tabbed with a screen and pig pads as the fairing lower has a split in the bottom and is two pieces, with dzus fasteners.
I found that I had a base gasket leak, that fried the rod bearing and a couple left hand pistons. So much for dry gaskets lol... anyway, it was at Nelson Ledges for the first trackway since the repaving of the whole track, and it was giving a Ninja 600 race bike fits, he could pull me at the end of the back straight by 100yds, but by turn 12 I was on his tail, and could pass him in the curves if he gave me a chance! He was part of a Moto America team too...
Well, here are the pics!

Good to finally see you over here Charlie, the bike is definately the real deal and goes well:)  Thanks again for the pics of the fairing mounting.  Ron is inspired to get his finished but he did have a bit of an accident, broken jaw, so he's excused a bit for now:(

Obsession is a great substitute for talent.

Peace to you also Cosmic, and Zedixe13, yep Prayer Changes Things. And thanks, Clem! Good to see you here, also! The pics were at Nelson, correct?  Or was it Mid Ohio, I forget lol... I forgot I had a login over here, but its a cool site, and started me off on a lot of ideas for the Rd350. I have a set of .010 over cylinders for the RD350 that I ported using Scott Clough's article on here, and they are awesome... I didn't have them on this year, using a stock set of .010 over cylinders right now, but those ported ones were Fast! It really was able to use the VM34 Mikuni's well, and I was keeping up with the SV650 guys down the back straight at Nelson Ledges two years ago using that porting!! The crankshaft is a Vito's and the pistons were off eBay, with ceramic coated tops, a non-friction coating on the skirts, and a dry film lube on the wrist pin. They have really good compression too! I hope Ron heals well, sending prayers his way.
I am using the Continental Classic Race CR compound tires on the 18" rims, and boy do they stick well!! As good or even better than the Pirelli SuperCorsa DOT's I have ion the 1989 VTR250 Interceptor...
Following the logic of the RD400, I have a longer swing arm (3") off of an XS650, and that really makes the bike handle well, and moves the weight forward to offset the wheelie syndrome that these bikes are known for. The Vision forks are trailing axle design, and there is a good handling bike with this setup. I have Mike's XS cartridge emulators in them, also, and am using 14" Progressive shocks in the rear.
Anyway, the bike is loads of fun, and it really shines when it comes on the pipes... those ProFlo chambers just Sing when they get above 7500rpm. I hope that I am able to run it some more this year, hopefully soon!

Yep, I had oil injection originally, and the clear tube to that cylinder got kinked, and starved the bearing. Alas, I went to pre-mix after that. Running the Klotz synthetic with 20% bean oil, and my, does it smell nice!!

Mid Ohio has to be a good track for a light weight machine. The two major straights are long enough, but getting onto them is the important part. After those it's nothing but turns.

Yeah, the turns are pretty cool, especially the blind left hand turn 6, I think it is, as you go down the hill... I don't get down there enough to practice, but on Sunday, the RD350 was turning 2:02 lap times, and that was pretty good for me lol... I was having fun chasing Neil Pooler on his CanAm 185, I think... He is a good racer, and I caught him on the last lap right at the finish line, the RD350 was on his right, and his front wheel was a mere 6" ahead of mine, he turned to look at me as he didn't realize I was there, and I held out my fist to 'fist bump' him right after the checker lol... he came by later, and told me how he had tried to pass me out of a turn, but the RD350 had too much acceleration for him to pass, so he set me up in another turn. Lotsa fun! That CanAm runs real well!

Sounds like you had a good time. M-O is one of my favorite places.

If you haven't already made it to Pitt Race you should try to get out there. The track is quite excellent and the facilities are improving rapidly.
