review

Huge glob of epoxy hanging around tip of magnet. Ordered it for a specific model and it does not fit. It is an M10. Should be an M8. Would use it even if it did fit. Worried about epoxy breaking off and churning around in motor.

Replaced the top end on my 96 cr125r! Fit great perform well but the price is the problem. For 70-80 bucks they'd be perfect!

Hammerhead Engine Plugs

These fit perfect, and look great on the bike!! They do not come with O rings so you will have to use your oem ones or buy new ones but they are only a couple bucks- definitely worth the money.

lully job

Ordered my wiseco bottom end kit and everything fell together. Fired up second kick, now first time everytime! I will run it very gently, because that is absolute key in a good engine as some do thrash and wonder why the cranks snapped or flattened bearings!!
