How To Change a Crank Seal on a Two Stroke EASY Fouling Plugs Burning Oil 

It comes in handy A LOT! 😂

Hey what do we do after we change the crank seal? Do I need to drain any existing stuff? cuz I changed it and I immediately notice a difference but looks like it needs to be cleared out?

Oof 😅 well I hope this helps! It fixed my bike

😳 that’s good to know! Sorry you had to learn the hard way 😅

I’d think the clutch basket was just throwing it out of the hole as it spun 🤔

I’m assuming your transmission oil is red? Common oil leaks are around the shift shaft, front sprocket, or possibly the kick starter. Unless it’s something faulty like a case seam is leaking or the crush washer on your drain plug is messed up or not there. This seal wouldn’t leak fluid on the ground. I’d lean towards the stuff I said in the beginning. Get under it and wipe the bottom of your motor really good and clean and then check it every few minutes and see what gets wet again. That’s a good way to see where a leak is coming from. Good luck!!

@@ToyShop9665 thanks man!

Uhhhhhh………. I gave it the ugga duggas 🤷🏻‍♂️😅 not all of them but a could quick jabs with a 3/8 Milwaukee impact while holding the basket with my hand 😬

@@ToyShop9665 good enough for me i guess ill do the same haha

Could be lots of things. I’m assuming it’s a two stroke? I was fouling plugs like crazy that’s how I knew it was burning motor oil

I’m sure it’s very similar

The bike ran good for the first 20 hrs of the rebuild. But then out of no where it started fouling plugs. So I started with the carb and made sure I didn’t have a jet falling out or anything and that checked out good so I assumed it was the seal. It did fix it btw but ya. That’s how I got to that point lol

@@ToyShop9665I think that might be the same problem for my 04 Cr85RB I wonder if I should pull the reeds, re jet, before I pull the case off? But bogs down smoke 💨 like crazy and no powerband and she leaks oil like a lot lizard in heat 😂

Possibly. I know because it was sucking oil here it loaded my silencer packing with oil and it would smolder and white smoke would roll out of the silencer even with the bike shut off. So it’s possible. But check to see if you’re using coolant or not. Could be head gasket.

It did! I haven’t fouled a plug since!
