TTR250 starter replacement using parts from another bike's starter motor
Permalink  
 

On my last ride the bike sounded a little more 'grindy' than usual when starting up. I figured my sprag clutch was failing as it's been clunking a little louder, but when I pulled the cover I found the starter shaft is missing a few teeth. The idler gear is missing one too.

The sprag clutch spins freely and quietly, but after reading this article: http://www.dirtybiking.co.uk/features/tech_stuff_2005_starter_rebuild.htm I'm inclined to replace the clutch as well as he indicates that the clutch could be causing the carnage.

My question is, what are your thoughts on these ebay starters? http://tinyurl.com/k6tqjww or http://tinyurl.com/m3l49re

There are a number of sellers with "New" motors for around $80, which is a lot cheaper than the $220 for an OEM unit. There are also some used genuine parts kicking around for about half that (teeth intact).

Any thoughts on what route I should take? $220 new OEM, $80 new aftermarket, $45 used OEM?

If the pinion teeth are perfect then the $45 OEM would seem the best choice wink

You are right to address the cause which is almost certainly the sprag clutch.

Thanks, Brian. I'm leaning towards the used unit. It's used, but so is mine and it still spins nicely. A newer used unit is probably OK too (it's also 6 years newer).

All in this will cost a few hundred bucks, too bad I didn't get to the sprag clutch sooner. Could have saved my starter and idler. Oh well.
