Lightweight Supersport Legality

[trace33chargers]

Is it legal to put a 2nd gen motor in a 1st gen (specifically SV650), but change it to carbs instead of EFI. I do realize the rulebook says OEM engine (6.1.2.A) but it all fairness, the engine is a Suzuki part used in a SV650. On paper, I don't believe anything really changed between these two motors. Can anyone shed some light on this. Don't be too mean.

Cams changed. Tensioner & shiftstar changed in 05. in 07 or 08 they went with dual spark plugs

as far as legality of it, im not sure. i cant recall if the rulebook allows updating in SS

And its not like you are bringing anythin new to the table, you will be running the same exact motor as others in the class, only differece is that the first gen might way 3 pounds lighter (pulled that out of my butt, might have read it on a another site).

As for as those changes, cams are the only good ones. Shiftstare won't really make you faster nor will quieter cam chain tensioners and TWF will tell you to put a small bolt in for the second spark plug. Zoran doesn't like that head.

Rulebook answer If the OEM part numbers are the same then it is legal.

reality no, no, no, and more no
can't use the 2nd gen case cause it is different
can't use intake cams in exhaust, that is not how it came from factory
can't change carb to FI or FI to carb
you can't pick the best parts from a model line to make your own version, in most cases later years have better running gear, systems etc but some models have price reducing revisions that result in a lower quality part used.

FYI that is not official answer as I am not in that position but from a long time racer.

If you have any question that something might be in gray area send an email to office and you will recieve a verdict in writing that can be used to support any protest.

No way, the motors have plenty of differences, not to mention completly changing the fuel system. Illegal in a lot of ways.

In supersport that is not allowed.If you do superbike it is ok.The first generation engine in superbike trim can be more powerful then the 2nd generation engine.

I just find it is weird that you can have titanium axles (not that they make them, nor would I buy them for my SV) and the way I interpret it you could get away with total loss electrical (no reference to charging systems, at least in the 09 book). I don't plan on doing anything said so far, but it's always good to keep my options open.

Welcome to CCS!  Ti/Alum axles, total loss, modified fork internals,  aftermarket brake rotors, different triples, different master cylinder, carbon fuel tank... all are Supersport legal.   CCS Supersport is not even remotely similar to WERA Superstock.  Supersport gets expensive fast!  Huh??

If only they would throw in the WERA Superstock umbrella rule, if it isn't listed you can't do it. I never thought about a carbon fuel tank. I wonder how much of this stuff Ed Key has on his amazing machines.

All of it.....

Yes!  All of it!

I love CCS supersport.  Building the bike is at least 1/2 the fun.   Honestly, its cheaper to buy your own machine shop than pay someone else to build you a nth level supersport bike.
