I don’t really see anything detrimental, other than the huge drop in performance.   The clutch might wear out faster from the starts.  If all you’re doing is joyriding, and not racing, then it should be okay.

12600 is really, really low max rpm for a leopard. You would have to lean out your low speed needles to get it to pull off of corners at all with that low an rpm. And since max torque is 10-12k rpm, right end the end of the straightaway just before you’re about to brake you’ll be in that max torque range the engine is suddenly going to take off like a bat outta hell. It will make for very sloppy driving. I think you are much better off revving it to 14,500 or so and just leave your high end needle on the rich side. You will be able to go 20+ hours without even touching the top end this way.

Edit: you could swap on a JR header and carb and really have just about the same performance as the KPV

As you stated its for non-karters to use as a play toy I would leave the gearing alone. Most likely they will not be able to maximize corner speed and would need the extra teeth to get decent acceleration. 15,600 is still fairly low on a Leopard. We routinely use them at 16,800 without any failures.

It looks like there are a couple jr headers, a 25mm and a 30mm. Any idea what the HP difference is between these? Perhaps a better option would be to drop the rear sprocket 5 or 6 teeth and then put a jr header on there.

[Rod Hawkins]

Also looks like there is a jr restrictor plate available any idea if that would work?

Another and perhaps the most logical thing to do would be to sell the leopard and throw a KPV on there. If it could be done without losing money on the deal?
