yea in hindsite I got the new bearings before pulling it apart, and probably would have gone ceramic or something a little fancier knowing now how much of a pain in the ass it was to swap em out
No, not really. But a cooler motor is more efficient.

Before adding the fins, the motor would get pretty hot after a long run but not so hot you couldn't hold your hand on it. At lower speeds climbing hills, heating will be more of an issue. The weather has been pretty cool lately, so not really needed but I'm sure it will help during the summer.
I don't ride hard enough to have issues with that. I remember seeing a picture of the sensor in one of the teardowns by Luna. I think its near the throttle sensor. It should be pretty easy to disable it if desired. It ties into the same line with the kick stand switch. Ideally it would have some kind of timer so it has to be triggered for a full second or more before it cuts off.pipeking wrote: ↑Nov 09 2018 6:13amanother thing I find interesting nobody has mentioned is the tilt sensor, and the issues you have with this if you ride the bike hard. I first noticed it landing from about 1m to flat the bike would cut out. You have to turn key off and on again before it will go, so bloody annoying. It will do it even when the bike gets a sudden jolt like bouncing over big roots or rocks.
Yep, sits in the bracket above the controller in a rubber vibration mount...
thanks for the share..fechter wrote: ↑Nov 05 2018 4:41pmI was looking at ways to improve the cooling on the motor (though it seems to do quite well stock). It seemed to me the skid plate was blocking most of the air flow that could go to the motor. It also serves to keep mud and rain spray off the motor, so maybe not a good idea to put more holes in it.
I thought about making scoops that go on one or both sides, but scoops tend to work only when there is nearly zero back pressure or else the air just goes around the inlet.
So I decided to try more of a wing or deflector instead of a scoop. The test prototype was made from a piece of polystyrene taken from a large 3-ring loose leaf binder. Those things that keep the pages from getting jammed on the rings. Any thin, stiff plastic stuff would work.
The plastic is very thin, about 0.7mm so it can slide in between the skid plate and the frame. I just loosened the two bolts holding the skid plate and slid the plastic into the gap, then re-tightened the bolts.
The plastic was bent slightly by heating with a heat gun.
The area exposed to the oncoming wind is now much greater but the wings don't stick out enough to interfere with my feet.
After running it hard for about 20 minutes, I stopped and felt the motor with my hand. It was barely above ambient air temp, but started getting warmer as it sat there. I think it works but needs a bit more testing. For sure it could stick out a little more without getting in the way of anything.
Mud will hit it, but it should be easy enough to wash off.
OK, I found the sensor and it looks pretty straightforward to unplug it. It is located just below the main circuit breaker. The sensor and main breaker are mounted to an aluminum panel that makes the front of the battery compartment. By unplugging the sensor, the feature will be disabled and could be re-enabled if desired by plugging it back in.pipeking wrote: ↑Nov 09 2018 6:13amanother thing I find interesting nobody has mentioned is the tilt sensor, and the issues you have with this if you ride the bike hard.
