A forum for owners of Yamaha TTR250 trail and enduro bikes!

Oh no Dan

I have been in the exact same place as you are now Was a few years ago and I learnt some hard stuff.

First make sure you flush the bottom of the engine out properly, when you get it back together use a magnetic sump plug. This will help pick up any stray bits that you do not flush/ clean out.

The parts you bought only came to me yesterday, so looks like that was good timing.

As for the starter we found the aftermarket ones to be of inferior quality and will not use them ( has any one found a good aftermarket one?)

There is some interesting reading about starters if you use the search facility above.

I used an old fazer one to convert and make it fit and it is still going strong

New ones from Yamaha list at £252

Bike shop mechanics should know better but my experience and DRZ owners on the local facebook page have come across some bloody awful mechanics

Just shoddy work, full stop.

You should have seen the wiring job the local suzuki dealers did on my DRZ just putting in a few LED blinkers

that's before I bought it, I wouldn't have paid them for it if it had been me.

gives me the horrors to think what they would get up to for serious repairs

Now you have bought the starter, just keep an eye on it.

Some had problems with the bushes I think, but the one I bought seemed to have a pinion made of cheese If It shows any signs of shedding metal get rid of it.

Hope helps

Trying to tidy up the starter motor information and found this old post:

I had are request from Joel in Australia for some ideas to sort out his after-market starter motor.

When he pulled the body off his starter's armature, the magnets had come adrift of the body (unglued) and hence got caught up in the starter armature itself.

This had been a bit of a problem for him over the past few rides, where the starter/solenoid would ‘click’ but no starter spinning up and heating/melting of the main starter cable if the button held in.

He thought it a dodgy solenoid but now realises it was because the starter itself was jammed up internally. This starter was lucky if it had 100 starts on it and a grand total of about 20hrs in service (on the bike)

This was the second motor he had bought from the same seller on eBay which both developed the same problem.

I have a box of dead starters most of which were taken out of commission because of damage to the pinion gear caused by a worn sprag clutch. I found a good body from an original starter motor and sent it over the water and was pleased to hear back that it fitted and the starter now works fine 

I have heard from another UK owner who had the same issue but resolved that with a replacement starter motor as we hadn't realised that the original starter body would work with the after-market starter motors - but we do now! 

I hope that may help someone now or in the future.

Thanks for finding that old post, I have now received the idle gear and the sprag clutch, just waiting on this potentially dodgy starter motor to turn up
