I understand a displacement limit has to be drawn somewhere but I had to drop 600 bucks on a set of cylinders because mine were just a bit too worn to hone and drop in std size pistons. A bunch of other classes get the 1mm overbore for rebuild purposes. I think SVs should get it too. OK, now all you FZR400 and Hawk guys can start screaming.... :biggrin:
I hear ya. it is the same set of rules for the Ducati 800 where there is no overbore capability. Live with it because the $600 is still cheaper than building the FZR400 to try and run with the SV in the stock form. I am running against some 80 hp SVs here in the Florida Region.

Probably because it's ULTRAlightweight superbike and they just let the stock-motored SVs into the class to run with Ultralight bikes. The SVs with overbores can be run in Lightweight classes because they are Lightweight class bikes, but you have to give the Ultralight bikes a chance to run in their own class. An SV with an overbore in an Ultralight class is seriously taking away the competitiveness of the other Ultralight bikes.
way back when i ran IHRA superstock they limited us to .070 overbore so when you honed the cylinders you could not run the hone up to the top because that's where they checked it. oh that's right ccs doesn't check anything but your air filter. unless you ride around thinking that its that 1mm that is causing you to beat the pants off that ex 500 and not the superior chassis or riding ability I would have gone for the overbore. it's probably only worth 2 or 3 hp anyway besides don't they plate those so going back stock costs the same.
Just put in a cheater airbox like Carl and Justin
HA HA
Punch that sucker out, nobody checks anyway.
Just don't beat me, I'll have my protest forms ready

They are by no means "stock motored" although many are for now. There are others that have high comp pistons flatslides and more. That is nowhere near stock. 80 hp out of a 1st Gen SV is not bad.

Gino,
Will you be running Ultralight? It would be fun.

80 hp is barely a decent SS build with flatslides. Ive had a few 90 hp motors come out of the shop with stock displacement. Yeah they were very tight, but they were all season or two motors. That is my only problem with moving SVs into ultra, they should have limited it to SS. That way SS bikes had two classes to be competitive in, while the SBs could run what they have been running.
Maybe the air is different in Florida but from most al the guys that I have spoken to and they are pretty good sources they have given me this information. Maybe they were just sandbagging me. My Ducati 800 produces 87rwhp on the superflow dyno of MotoCorse. I thin that is pretty good. On the same dyno a Dcati 1000 DS will produce 92-95 hp.
It would make more sense now that my 87 hp couldn't run down the SV with a claimed 80hp on tap.
Mark
a lot of those bikes are run on Prieto's Dyno. That dyno reads notoriously low, so if a sv makes 80hp on that dyno....it is seriously fast. My .02
Just like guys that say that have a 125hp 600. The strongest 2mm over SB made 120 on that dyno.

Will that increase my Karma?
Seriously, I'd love to, but I only have the 1000DS and the 748 / 996. I have been keeping the 1000 stock so that I can continue to run in supersport. Just an interesting point, with the stock airbox cover on, my 1000 made 85 HP on the MCP Dyno...this is one of the reasons we thought the bike was sick. Pull that cover off and she jumped to 92!
I always thought the bike was faster with it off, but I just assumed it was a mental thing because the engine was so much louder with the cover off. For the last year, I haven't even bothered pulling it off for the GTL and LWSB races....but I will now!
That's not too good. Makes sense now why my 800 can keep up with your DS. Looks like my 800 makes more than your DS with the lid on it.
Mark
I'll be happy if the bike makes 84hp with the stock bore. That's enough to play around in ULWSB in CCS and LWSB in the other race organization,
