I could build one but dont have a bike to use for the template. I should get a bike to replace the old seca. Im sure it would be more fun that that old pig.

Yamaha Seca II 600? Yah, those were neat. My 1991 Suzuki Bandit 400 was similar (and just as fast).

Perhaps you need a Super Single template when I am near completion!

Lol no his is original Seca not a Seca II his older seca has some power. Those Seca II's were the most gutless bike I have ever ridden. Handling was nice though. I believe that was first bike I ever rode with Radial tires.

Yeah, I agree, terrible 600 the Seca II was. I had a 1991 Suzuki Bandit 400 that kept right with it. That always surprised them and made me grin!!!

Mines a 750 but is in need of a tuneup. The most comfortable bike I have ever rode on long trips . After rebuilding the forks it rides very nice.

Just got a quick race update from cdale55. He said the untuned duals feel like they make more power on top. The 505 had the ponies to win the pro class race. We really need to get that thing on the dyno and I should be ready for next sunday. It worries me that it's racing without any proper map for the new system. I hope it holds together for the rest of the races and isn't too lean. That would suck to burn it up.

Heres my left side duals that wistech talking about. The muffler has two- 2 inch cores inside for plenty of flow. will also have another muffler done for next week that uses the same header but has a 2.5 inch core to try on the dyno next week.

To bad they dont stay that color after running the engine. They look cool though.

Looks nice, the can is not really my cup of tea though. I would prefer two skinny cans, similar to GP bikes...
