Engine Trouble Jap crap

[Jap crap]

Sounds like you lost one of your crank case rubber seals, there is one on the mag side and one on the clutch side. It might just be displaced and not damaged. Check it and make sure it's on correctly and not damaged. The loss of the seal causes loss of compression and bogging. Make sure you clean your clutch pads of oil so they don't slip. If you need a new seal they sell both seals together but they are cheap

What do you guys mean by "4 stroking"? Call me stupid, but that doesn't seem to suggest anything to me.

When it's rich enough that it only wants to fire every other time (once per 4 strokes vs 2.)

Clutch side crank seal is probably bad. That should be the only way you would be getting fuel around your clutch. Four stroking usually means the engine is running rich, so you could try jetting down. Before you start tuning the engine or adding more high performance parts you need to fix the issues first. These engines actually run quite well stock if the ports are cleaned up and everything is setup correctly.

What seal do i need for the small gear on clutch side.i dont want to order the wrong one its an 80

Your side seal beneath your mag is defective need to replace in a hurry before engine death cost about $7.00 then shipping for now take your bottom forward bolt out to prevent mag and vid shirt out.

There's a metal spring inside the seal but Ive not seen a metal outer ring before on these.
