    I just thought I would share my Seca race bike.

    It has a stock motor, stock carbs with the rubber velocity stacks from the original air box and a MAC header pipe for a 650/750/900 and a Automotive exhaust tip on it. It runs great although it is down on power to the GPZ 550s just like back in 81.

    I have wheels from a CBR600F1 and forks and brake calipers from a VF750 Interceptor on it. I have 110-17 Metzler Racetec on the front and 150-17 Metzler Racetec on the rear. It has Progressive suspension shocks on it that are an inch longer than stock to quicken up the handling a little bit.

    I put FZ600 rearsets on it with an FZ600 rear brake caliper and M/C and an FZ600 upper fairing. I still need to stiffen up the front fork springs a little and dial in the damping. All in all it is working pretty well, but I need some more power. I have an extra FZ600 engine so I can put the crank, cylinders and head on the 550 cases and still be legal.

    You could fit a 160 in there, but the rim really is too narrow for a 160. The bike doesn't really need any bigger for racing.

    did the header pipe for the larger engines need any modifications to fit?
