Just got a 1996 yamaha jog

[eliteguy50]

there are aftermarket rotor kits. this replaces the stock heavy mag and stator. the aftermarket ones are aluminum and weight about half the weight of the stock mag/flywheel. the ncy ones sell for about $250. the malossi ones are about $450. all the guys in europe that race minarelli motor bikes use rotor kits on their bikes. makes it rev up quicker and frees up rotational mass weight off the crank.so that means more hp too.every little counts in these small engines.

When you get to that level of performance, you should also remove the oil pump.

Are there oil pump plugs for the 1996 jog?

Where could I find one?

You don't need one. The pump is driven outside of the crank case. Just pull it and cover the hole with some scrap whatever to keep debris out.
