Lucky me.  Coil bind (or whatever is causing internal fork 'bottoming') occurs here, and no tire-to-header contact occurs.


How much tire expansion do you get with those tires when they are run and heat up? Looks awfully close in the picture.

There was some discussion about this on another site.  I think you're supposed to add something like 3/8" for tire expansion, but more of the expansion is due to centripetal force than heat expansion.  If hallon's ever in a situation where he has the wheel turned this far to the side at highway speeds with the forks fully compressed, he's got a lot more to worry about than melting some rubber to his pipe.

As always, nice work HonkyKong!  Can't wait 'til mine is a roller and we can knock these both out as "done"!

I'm reconsidering my lack of front fender. Not for any functional reasons but just because I threw a Burgundy Sportster (or any Harley with a NarrowGlide) front fender on it and I like the shape and even the color.

Fresh_c has suggested I consider an oxblood color somewhere in my paint and although I was thinking more earthtones it could look pretty good.

LOL True, you ain't lying there. I was thinking more of tighter parking lot manuvers after a decent length ride.

Diggin the build, looking tits'

This tight clearance was only with the forks ratched-strapped down to their fully bottomed out position.  Parking lot manuvers allow several inches of clearance.

Please excuse the lack of updates lately.  I've got a baby boy due any day and preparations have taken priority. I'll get back to this after the new year.

Thanks, all.  The little free time I've had has been put to making 'art' from my leftover parts pile.  See link in my sig.
