650 rebuild/Jet or Carb Upgrade?

I have a 78 650B and need to rebuild and rejet the carbs for header and pod filters and because one of the gaskets has started to weep fuel. It's about $100 for the rebuild kits so I was wondering what other options there were as far as getting an entirely differnt carb bank from a diffent bike for better performace. Thanks for your help.

Bumping up to vm26's (stock are vm24's) is a HUGE performance gain. I've heard from others that vm28's run nicely on our 650s as well. Some of the kz900/kz1000 ran vm26, some ran vm28. You can also use vm26's from Suzuki GS750 (same spacing) although there are slight differences between the Suzi carbs and the Kawi carbs that will lead to a bit of a tuning challenge if you go that route.
If you opt to run bigger carbs you'll have to get new carb holders to accept the larger diameter outlet of the carbs, plus you'll likely spend close to $300 for a set of rebuilt and ready to bolt up carbs, over $100 for a set that needs rebuilt (which would also need the $100 worth of rebuild kits). SO, if you're looking for the best for your budget, you're better of rebuilding what's on the bike now. If you want to pick up some performance gain and spend between $300 and $400 by the time you're all said and done go for the bigger carbs.

Thanks, that's what I figured. I just ordered a (4) rebuild kit from Z1 Ent. I want to get it back on the road ASAP, we don't get that much sunshine outside summer in Western WA.
