Kickstart shaft retaining pin
« on: August 07, 2008, 10:09:49 AM »
    Does anyone have a successful method for removing the roll pin that retains the kickstart shaft on the 750's?   I need to inspect the shaft and gears but can't until I can get this pin out. Am afraid of mangling or breaking the protruding end by trying just pliers or vice grips. Thanks. 
Give me..a frame to build a bike on, and my imagination will build upon that frame

Coincidentally, I just took one out on my spare engine I stripped (bound for the next project FreeBird II)  After much consternation, I gripped it gently? with vice grips, closing the gap in the pin a little bit, then tapped the vicegrips upward and the dang thing moved up. I repositioned the grips so as to close the gap a bit more, tapped it again and it moved up more. Rinse and repeat. It was out quickly.

Good luck.

i've also used some large channel lock pliers, gripping and slightly twisting as you pull up. i posted a thread with the same question a little while back, having one that just would not come out. i had to lube it for a week, heat the case, and pull with a vice grip while prying beneath it with a flathead screwdriver.

All good advice. Soaking, heating, twisting and prying likely all preferable to tapping.

Ultimately, I was surprised how easily mine came out, after having agonized on how to do it for quite some time.

Grabbing it with sidecuts and levering it out sounds fair.

That's exactly how I did mine, Kevin.  I've pulled three of them this way recently, and in fact this is the ONLY way I've been able to get them out, vice grips were a no-go for me, but this got them right out.

I was more worried about buggering the aluminum boss that the pin sits in rather than the pin itself, but I had no issues with that.
