Stator problems/replacement.
Hi !
A few days ago I whant to go fore a ride with my 87 mod Tenere (1VJ) but would not start because the battery was emty, has been sitting fore a while, charged the battery over night and next day it started and I start riding. It has been something wrong fore a short time, lights are following the rews. Before I got home the ligts was very bad, when I got home I checked the charging and it was jumping from 5 v to 10 v depend on rews. Then I changed the RR and it was the same, then checking for contact between the 3 white cables from stator and there is 0 readings when engine is running and there is contact between all 3. I asume that the stator is broken and need a replacement, have been checking on internet (CMSNL, Wemoto did not have)) for a new one and the prices are very high, 665 euro. Is there any chance there is any interchange between models or do someone on the Hubb know where I can get a new one cheaper ?

Carmo electronics in the Netherlands quoted me €217,20 (including 21% VAT / excluding shipping charges) but you have to send them your stator for rewinding as they have none in stock to swap. They said it would take three to four days. I didn't actually use them in the end as my problems don't seem to be to do with the stator.

Wemoto in the UK offer one by Electrex for 90£ (http://www.wemoto.com/bikes/yamaha/x...-_by_electrex/) but I've not used them so don't know if their stuff is any good.

I have a stator for sale, I can send it to you. I can check tomorrow if it fits your bike.

70€ + shipping, should be about 20€...

I've bought a number of electrical bits direct from Electrex (they're only a few miles from me) and it's all been good but at a quick glance I don't see a specific listing for an 87 Tenere stator.

I've had a couple of stators rewound by West Country Windings (I went through a phase of bikes with dodgy electrics) and they were also pretty good. They seemed v professional when I called in (workshop was just over the road from where my parents used to live) and as neither of their rewinds burnt out again what more can you ask.

It may be a bit of a pain to have to send the old one from Norway but at least you'll know it'll fit when it comes back. Cost wise it was about the same as an Electrex replacement but postage might bump that up a bit.

There should be plenty of places who offers to rewind the stator.

Rex's Speed Shop - Sales 01580 880768
Ricky Stator - Manufacturer of ATV and Dirt Bike Stators, Electrical Components, Lighting Systems and Suspension Products

For a new one, have a look at the "G45" on the link below, looks like a straight swap, and its only 87£

"New replacement Alternator Stator to fit :- (Stator Size 115/54/17mm). XT600 (84-90) ":

Hi, what do you mean by 0 readings? My 1VJ stator had a couple of broken solder joints where the white wire join the enamelled stator windings causing poor charging. Perhaps yours is also broken. A tickle with a good soldering iron sorted it out.

A stator from '91-'07 KLR650 will fit as well for a lot more options.

Thanks for all the tips.
It`s on hold fore a while due to building a carport before I whent to work.
When I`m back home again later this year I will do some more checking around the problem. Will at the same time change the bearing for eletric starter that is broken when I`m first in there.
Thanks again and I will keep posting when I know some more.

That one is for the later bikes with TCI systems. The diameter is smaller and they lack the windings for the CDI. Also there is just one timing pickup, the cdi types have two.
I fitted one of these to my bike (1VJ) when I re-engined it with a 3TB motor, and other than having to open out some holes because they were in the wrong place, it works fine and is so much cheaper than genuine.

A small update on my stator/charging problem.
Took me some time to take of cover and have a closer look inside, it do look good so I took the stator to a generatorshop to do some checking and they found nothing wrong so far. Start thinking it can be the regulator that make the problem or the battry, will buy new both.
When I`m in there it is time to change the starter bearing that have been not working for a long time, I have a new one waiting. Got the nut off the flywheel and now waiting for a flywheel puller to arrive, hopefully it will be there when I get home from work in few weeks.
Some pictures from my garage and the bike.

Got my puller a week ago and got to work, now it have been sitting there with pressure on and the flywheel still stuck, have tryed to warm up with a small torch, hitting it with my big hammer but no f..... way it will come loose.
Any god ideas that can be used to get it of ?
How hot can it be before there will be a problem with magneto ?

-------------------- Heat
It is the difference in temperature between the shaft and the collar that is important .. not the total temperature.

So you want a lot of quick heat not slow heat. You do want it where your heating it, but something more powerful than what your using.

Temperature wise ... any seal on the shaft will melt if too hot. Oil will start to boil. And the magnets loose strength. I'd limit it to the boiling point of water.

------------------- Impact
Hitting it with a hammer .. where? The hit should be no top of the single long bolt you are tightening ... with the biggest hammer you have. After each hit check the bolt is still tight.

Good luck.
