Couple of observations about the DT 300i

[CROSSBOLT]

First, I would like to gripe and criticize: Why put the excellent white LED helmet/luggage tub light in THE BOTTOM OF THE TUB!!! Anything in that tub will block the light. Duh!

Second, the back brake seems to have a slight drag on it after riding. It is not really bad and I do not notice any drag while riding. Just when I park it on the center stand and spin the wheel it spins reluctantly. Works almost OK after it cools off. Disc does not get hot but the caliper and surrounding area is heated by the muffler. Yeah, I know. Don't put it on the center stand and try to spin the wheel after riding!

Lastly, the CVT box gets HOT! I guess that's why they put those stylish heat shield covers over the metal cover.

Are you sure it's the brake? My rear wheel is sluggish to rotate but that's because your
moving all the gears and the clutch. There's a lot of mass there...

[CROSSBOLT]

Yes, since I removed the brake to "prove" it was the brake dragging. The wheel, gears and clutch rotated freely and would coast to a stop. Put the brake back on and everything was free. Took a ride and the brake would drag slightly. Let it cool off and all was well.

Brakes really get hot and yes, they do drag and it's normal... especially motorcycle brakes... that's why they require DOT4 brake fluids that have higher boiling points....

[MotoRandy123]

I've seen some that drag a tiny bit and some that don't. There's no mechanism to fix it though.
The anti rattle clips will help if they are fitted originally. You can try lubing the pins and cleaning
and polishing the metal on the pads that they move on but sometimes they just don't move back
like you want them to....

Is the stylish heat shield cover the same as the duct that pipes in air from the front while keeping out water?

[de dee]

  yes that is the tranny cover ,. short air intake in front and the puke tube is held by a   little clip in front on the inside ,.  should be cleaned out , I do mine with oil changes,. 1/2 inch tube with plug in the end. you will find it when you take the first cover off.

Yes, that's why some open the cover or drill holes on them.....

Here is some more: Had a couple of good trips and noticed tranny oil seeping out of the fill plug. I changed to synthetic recently an noticed that there was no gasket/washer on the fill plug at the time. Cleaned off the seeping mess and made a washer out of 1/16" gasket material and installed. Checked the parts pix on line and there is not washer/gasket. There was no such thing on the Yager fill bolt but it never leaked. Just finished a couple of hundred mile trips and no seeping so far.

I also noticed there was no washer on the tranny fill plug when I changed my oil. So far mine is not leaking (yet)

Got a good one: Nearly all the PH2 screws that will be removed for some kind of maintenance have Taiwan Tinnerman nuts! These are actually better quality than most aviation versions since they are all cad plated. The ones that take machine screws are like Tinnerman nutplates. Very good stuff! This is the way it was/is on all three of my Kymcos.

Anyone else notice that when your stopped on a hill with the rear brake on, it makes the whole scooter shake a little. I know it's just transferring the engine shake straight through the brakes but just saying.
