Hi De Dee,
Welcome to the club of dead DTs. Mine died too in April. The conrod bearing decided to call it a day. Got 84,000kms out of her.

For the tire wear, I too was getting similar miles out of my tires too. In general, 10,000km for the rear and about 25,000 for the front.

Besides the kill switch at the side stand, the brake switchs at the levers, I too have had failures to start on my DT.

The relays hidden in the front side cowls too could have crapped out. Happened to me once.

Had that happen to me when changing the rear tire.
The workshop had to continuously spray carb cleaner to get the rust out. It's due to rain getting in there, perhaps insufficient grease on that shaft.

I think it took about 30mins of spraying carb cleaner and tapping with a rubber mallet to finally getting it off.

Definitely the head bearings.

Have the top and bottom ones replaced and you're good to go.

Somehow, it is a common issue with the DT, some have said they come under lubricated from factory.

Just got the bike back what happened is one or two of the rollers were flipped over! He asked me when it happened how hard I was braking.  I was stopping hard for the berry stand on the side of the road   He said I very soon will need a new clutch or get the Kymco rollers.

That is one issue with Dr Pulley sliders.

Tech Pulley now have little 'wings' that prevent that flip over.

Perhaps you can try those.

Hi All,

I am in the mist of buying my gear oil for the rear end.

In the owner's manual the recommended is a SAE 85W GL-3. Now those that tried looking for a GL-3 gear oil would know that it has been discontinued. Replaced by GL-4/GL-5 and recently a GL-6 has been introduced into the market. The rating was established by the folks that created the API standard.

I would happily go the GL-5 route as it is easily available. But it seems there are claims that the GL-4/5 will corrode the yellow metals in a gearbox. So my question is does scooter gear boxes have any yellow metals?

I tried looking into scooter specific gear oils but Shell, Castrol, Yamaha and they all are mineral with no info on their API service classification ratings.

And help would be great.

Thanks.

In Malaysia, majority of the locally and Thailand manufactured vehicles mainly use Denso, especially the radiators.

That's a shame - don't see so many Densos here in the UK.
