do not use enduro max bearings they don't last as long. they are still working in my motor but I've been advised they a not suitable for motors. I'll post an update but so far I have no issues with them personally
This is not a how To video its a how I did it. Follow this video at your own risk!
obviously this will invalidate any warranty so wait till your warranty has run out before thinking about this.
my best advice is to contact performance line bearings and get a full motor service there.
if you are servicing motor yourself they supply parts tools and correct lubes.
more info on the work done.
if you look at video at time 5.33 you see me point to the bearing what you can also see is the staining to the case that tracks the water ingress. the main way water gets in is through the bearings
I actually coated the board with 3 heavy coats of conformal and not one shown in the video
I blocked the old vent with silicone and routed the new vent to a dry area up inside the frame
the vent was made from modelling tube 3.5mm . drilled a hole same size and locked it in with lock tight
I used silicon tube but this kinks easy so a different tube that doesn't kink would be better. it's extremely important it's not blocked.
I had good success on two motors.

I have a pw-se since 2018 and it's been under water several times including the battery connector Done 4125 miles so far never been opened and still runs like first day I'm speechless on the quality of yamaha motors especially the old models Sometimes I crave a new bike but I don't have a reason to get a new bike because my old sduro still runs just fine

On the older Yamaha motors the bearings were much bigger and lasted longer. If you look in the description of the video there is a link to lake district video. Then you realise I ride very wet long rides. A Bosch motor died on that ride as well. There all constructed similar and all get water in them it just depends on how often you ride wet and how good the bearings are for how long you get away with it

Circuit board? Use conformal coating for electrical board! Die electric grease for connectors .

Hi can you clarify the question ❓

Great video. How did you seal the remote vent tubing into the motor housing?

@LazyMTBrider 4 ай бұрын

Hi I just used some locktite seal and lock. The pipe is modeling tube from eBay. In next version I will use a threaded barb.

@@LazyMTBrider Threaded barb is a good idea. I think i have the same motor on one of my eebs so this will come in handy. Thanks

Wouldn't petroleum grease be better for the connectors, we used to fill all our electrical connections on our motorbike enduro bikes for beach races etc, especially on KTM's?

@LazyMTBrider 3 ай бұрын

Petroleum grease is better lubricant but that's not necessary hear. Silicone is more inert and better at higher temps. If you do a long mountain climb the outside of the motor can get extremely hot. Probably even hotter inside. Silicone is more stable in heat. So over all I think it's best for job.

Can you seal up these middrive motors to reduce the noise levels?

@LazyMTBrider 2 ай бұрын

Mid drives are ushally sealed from a noise perspective. Depending on the noise it can be a indicator of a failing bearing

Where did the vent pipe go to?

@LazyMTBrider 4 ай бұрын

I routed the pipe up inside the frame tube it's dry up there on my bike . I've added some information in the description that will help. Please subscribe

It's ridiculous really that the tech is designed without properly acknowledging water ingress that causes so many problems. I'm on my second Yamaha PW ST motor after 500 miles in and 3 months from getting the bike new. It rains here in Wales and I can't split open a motor as will void warranty.

Ride it like you stole it until the warranty is done then learn to service it yourself
