Not as much as you are probably expecting!
StephenRC45 had an RGV500 (bored out) on the dyno a few weeks ago and it was pretty disappointing. Well, not exactly disappointing, as we knew it wouldn't make the power RG owners all claim, but disappointing in the fact that the increased power over a 250 wasn't really worth the sacrifice in weight.
You are adding like 2/3rd more engine (extra crank, extra barrels, and it's a big motor!) and only making 40% more power. It didn't rev either, but it did sound the bollox! I almost wanted it just 'cos of the noise!
The 21F3 would kick its ass on any road or track, but if you are into Suzuki's you'd just have to build one!
