    Made the front stays for the fender, it can easily be slid up for more clearance if needed, like in mud..

    Nice build. I'm guessing you got the 1200 and not an 883?

    There’s a guy in Sweden who has taken his Sportster up to two litres, and has if I remember correctly 160 rwhp. If you need some aspirations, I mean ;)

    Bought a cheap exhaust from Danmoto, not realy the look I wanted but the headers are separate pieces and the collector part of the muffler.
    That way I can buy a collector later and fab up something higher...

    That's Jörgens Sportster, know him from XLForum. Actually helped him a bit on the wet-sumping issues he had, hi did the modifications I came up with to the oil reliefe-valve, routing it to the tank instead of the sump. That and a improved pump solved it.

    Just found this build, nice job.

    A word of caution regarding Ti axles : "Back in the day" roadracer Dale Alexander tried a Ti front axle on his Kaw road racer (this was early 1970's) and quickly discarded as it adversely affected handling. Seems it's not quite rigid enough for the rigor of axle duty. There may have been other issues on his bike but all I'm saying is when you get it to riding condition and have handling questions, don't forget to replace with steel and re-test. If it works, then great! if not, be safe with "an abundance of caution."

    What kind of brake setup did you have on the original fork and wheel?

    That was a 14” Arlen Ness disc and the rear caliper of an BMW K1200S.

    Great looking build. If you've never ridden a 5 speed XL, you're going to love it!!! Have owned 4 and 5 speed XL's....I'll take the 5 speed.

    My front fender project is on a hault due to clearance problems from that wide BMW wheel.
    Season started and I do not waste riding time in the workshop.
    Bought a cheap mx fender, here's a pic from my beer run to Sweden today...
