R3 with Armour Bodies

Just finished my first track day of the season with the new bodywork on my R3. It's Armour Bodies Supersport kit which I had profe$$ionaly painted. Cut the vinyl myself, so that's a work in progress. Discovered late in the process that the belly pan would require major modification to clear the stock catalytic converter, so that stayed off for now. I'm planning on running MotoGladiator Superstock class which disallows intake mods, so unless I can find a muffler/exhaust that wouldn't require EFI retuning, I'll keep it like this for a while. Besides, I don't mind a quiet bike.

One of our national race series (R3 Cup) didnít allow pcv/Bazzaz etc. We werenít getting any power gains but the weight reduction was worth while and the bikes lasted like this for 2years without anyone complaining of engine damage (change in rules this year now allows them). There was more power with the Akrapovic when the baffle was kept in (untuned)

Agree. Should use full exhaust (and ECU flash maybe?), without a piggyback system. Weight savings alone are great result for going full exhaust.

Also agree with keeping baffles in for exhaust cans. No backpressure makes small bikes less power (with baffles removed), was true even for Ninja 250/300's

Thanks for the input guys. Just checked on a couple of the Akrapovic full systems and they do mention "Fuel remapping not required". Hadn't noticed that before. They also list power gains, so I guess we'll see. The Racing Exhaust shows a gain of 3.3 HP and a loss of 11 lbs. So for $750 that's $250 a horsepower, which really isn't all that bad.

Thanks for helping me spend money!

This dude's selling an Akra kit for a decent price; it's the same one I have on my bike and I have no complaints.

Thanks for the heads up, but I'm close to pulling the trigger on a Graves Cat Eliminator system. Just wast to make sure I know what needs to happen when you eliminate the O2 sensor. For the class I'm planning on racing in, ECU flash is not an option.

If you flash the ECU when you install the Graves cat eliminator it will run even better.

Yeah, what VULGR said. I want to stay in Superstock class. Flashing the ECU would put me into their 300 Superbike class, which would get even more rediculously expensive. In the meantime, I can divert some of those funds towards training. And track days. And food.
