Hi peeps,
I'm just back from an amazing 10 days at the IOM TT, Fantastic weather, amazing racing and unbelievable speeds, the only fly in the ointment was my Tiger.
I Was stuck in the traffic heading up to Bray Hill, right at the front of the queue at the traffic lights, they go green, I stall the bike, clutch in, Press Starter .... nothing but a sluggish half a turn of the engine, I think the battery is flat, jump off and push it across the road to the petrol station.
10 minutes later, after checking wiring for tightness we bump start it and find a really helpful guy in a garage with battery tester, the battery checks out fine.
Come to leave the garage and the bike fires up no probs, get back to the campsite through heavy traffic, and the bike shows the same symptoms and won't start, Fires up later no probs, and so it continued if the bike was hot it wouldn't start.
I had a quick look around when I got home and the Starters are suspect,
Anyone had any recent trouble with the starter motor?  Did you repair or have to replace the starter?
Any advice or suggestions before I pull it apart.
Thanks in advance

Mick

A few -me included- have replaced the brushes to try and improve intermittent starting issues.
For me, it worked and I've not had any issues since, others weren't so lucky and sourced a later motor, rumoured to be an upgrade from the original.

+1

For me new brushes worked for a while but a replacement starter motor was eventually needed. Has been fine since.

When the original starter was acting up the symptoms were identical to gixermick's.

Had the same problem. Managed to source a reasonably priced replacement starter on eBay. Not had the problem since. My original was the later part number and had only got ~12k miles on it.

You didn't say what manufacture  year or mileage on your bike, but, assuming it  is pre-2013 and has over 35k km,  then likely to be the hot-start problem encountered by many here. If so, suggest you bite the bullet and just buy a new replacement starter motor. Optionally you can replace brushes and refurb, but long term success doing this is uncertain.
In hindsight I'm glad I replaced mine. (Of course, the Triumph price is breathtaking, but typical of them.)
Plenty of write-ups about this on the forum.

Most forum posts have replaced with new Triumph OEM motor. Not sure anyone has had any success with alternate supplier.

Just recently had the problem. Removed the starter, stripped and checked it was pristine and brushes OK. Took it to a specialist who said there seemed to be nothing wrong. So not wanting to have the problem again fitted a new starter and battery. Everything has been fine since.
BTW my new one was 5543 not 5542.

Cheers peeps, there's a couple of second hand starters online, but don't really want to spend cash on someting that may be as bad as mine, spoke to Triumph Newcastle, they wanted 485, the parts guy didnt know there was a problem with them :114:, gonna live with it for a while i think,
Thanks

Mick
