YZB Kickstarter boss
« on: August 22, 2013, 09:51:07 am »
Gurus,  thought I would start here - does anyone have a kickstarter crank boss - 431-15621-00-00 - they would not mind parting with - for a price of course?  Mine snapped just very recently and not that many around.

thank you

Not cheap but hey, nothing else is for a YZ-A/B either ::)

Or, you could spend $114 less and buy  the very similar DT2MX version. Methinks that other than the model prefix on the part# they're the same item.

Both lower boss and upper off the RD 250/350/400 will work. The 431 and 278(RD) uppers are a little lighter and chrome  but tend to bow out after awhile.The RT/DT2MX(322) upper is cad plated but stronger.
