I ride my D12 and can change the oil, and thats were it stops, so for a mechanical nobody like myself, can someone tell me in laymans terms, what the heck is a sprag clutch, is it the clutch, is it something to do with the starter motor, is it somehow linked to both things? Do I even have one, like i said confused after reading through a few threads.

Cheers
Ross.

You have one, if you press the starter and the bike starts ok...it's ok, if it makes a noise and then doesn't start it's broke.

It's the bit that connects the starter to drive the engine over....keep a good battery and your fingers crossed, if your bike is 98' (I think) on you'll probably be ok anyway as they uprated the part ;-)

You are currently doing far more important work by changing the oil regularly...keep it up !

Hate to be the bringer of doom & gloom, but I'm pretty sure the sprag upgrade was '96 & it did not solve all the problems. I see a fair few complaints over in the Sprint forum about sprag clutches on 955s & even the new 1050s. :(

On the bright side, though, keeping the battery in good shape seems to be the proper way to prevent problems with old or new sprags.

This has me thinking now... Do we know of any sprag failures that weren't caused by low batteries? If so, what's the proportion of battery-related to non-battery-related?

Cheers,

Thanks for the info guys, think I'll go and get myself a gell battery, as a bit of a saftey measure, don't have any issues currently, and sure dont want any, they sound like a pain in the arse to fix.

Best plan is to always keep the battery charged. If you go to start the bike and it seems slow/ reluctant to start then don't try again without first charging the battery. Seems to work for me. Also a quality lead / accid ie Yuasa is as good as some lesser Gel types. I looked at getting a Gel type for mine but they are VERY expensive and difficult to get in the UK. I am told that HD's use a suitable Gel battery?

Not sure what would be different in the UK, but here in the US a sealed battery usually goes for $10-20 more than a non-sealed.

I think we can add the lack of headlight on/off switches in the US as a contributing factor. It just seems to me that leaving the one (or two on some) headlight bulbs off until well and truly started is what the electrics should be doing in the first place. Given that they don't on the T3, I put the Euro switch on mine. Proportion of Euro vs US/Australia sprag failures?

Not sure in the end it would keep people from trying to crank with a flat battery but I'd think it would help make it less flat. Mebbe a min voltage to crank in the first place. I wonder if you could kick start one of these if it came with the hardware (gasp!).

Geez, there was a time when kick start was all you had! I'm sure you could kick start a T3 if so fitted.

We used to call electric start an "over 40 button".

Cheers,

Gel batteries in the UK don`t cost that much and this is a straight swap over as i`ve just replaced my own battery.
