Hey folks.........been a long time! My scooter has been running like a clock but last evening we had issues. About three blocks from the house with both my wife and I on the scoot I started to hear a clacking noise from the rear end. It seems to be coming from the axle/wheel bearing and not from behind the variator housing. With the wife off the bike I was able(driving very slowly)to get it home. I'm just shooting this thread out there just to get some ideas of what type of diagnostics I should do to try and narrow down the problem. My first thought would be to pull the rear wheel first. Any help is greatly appreciated!

bearings breaking up it sounds by what your saying to much grease LOL

I'd wager a guess at rear axel bearings,,,,put it on the center stand and see if the wheel can be moved there should be no lateral movement at all

[burrhead]

Here's a picture.......looks to me like a plug fell out.......is this where the wheel bearing grease is injected?

[burrhead]

When I spin the wheel I get a grinding sound and feel......gotta be wheel bearing! Can anyone recommend the best bearings to use?

[richardthescooter3]

Did you check gear oil?

[richardthescooter3]

Did you check gear oil?

[burrhead]

Not yet but does anyone know if I am missing a plug? I will have to remove the variation cover to check gear oil and I will do that too

[cyborg]

Plug is missing and if you have roughness the bearings are most likely bad,,,

[burrhead]

Cyborg.........is this where you would pump in grease for the wheel bearing where the plug is that is missing?

[burrhead]

O! Guys......got a chance to remove the rear wheel today and found the problem......and I'm sure I caused it! There are three Allen head machine screws that hold the rear brake disc on to the rear wheel. One of them back out enough to rub/scrape against the rear framework.......see pictures. Tomorrow I will attempt to find a shop that can tap/clean out the hole so that it will accept either a new machine screw of the same size or the next size up. I say I screwed this up because I had to buy a new rear wheel and tire last year because of a bad blowout that I had in New Orleans. When I installed the brake disc to the new wheel I did not use locktite! Damn!!

Anybody out there have any idea what this plug that I have missing is for! Is it a place where you add some type of lubricant for the final reduction gears? See photo......

[richardthescooter3]

Hey burrhead, I had a rokdta 250 scooter and it had a plug underneath to draun oil and one on Top to put it in. If you have a plug on top, maybe that the drain?

[burrhead]

Richard........this hole that I think is missing a plug is not behind the variator cover.......look at the picture again......the fill and drains that you are describing are for the tranny lubricatio and you have to remove the variator cover to get to them......Dave(Burrhead)

My rokdta I didn't have too, it was right in the back like I said
