Not a chopper but the motor is a Yamaha XS1100 barrels crank shaft and cylinder head. Used 85% Nitro as fuel consuming a quart be second. Best 1/4 time was a 7.1 seconds. Have updated now to all custom made motor and improved reliability and time down to 6.5 seconds. Had to retire from racing.

Just a quich shot of my bobber. Need to finish this off so no chopper build for a couple of weeks while I get it done.

Again a few modifications will be required to fit caliper to front wheel and springer. Being a six spot calipier it is drastically over braked, a little air the system might be required.

21" front wheel with Avon tyre. Very narrow.

Springer was made for an XS frame neck so a couple of bits had to be modified but all fits nicely now.

Fitting the bearing cups was hard going but finally seated.

Rear wheel is 5.5" wide. Tyre fitted is a 200mm which is to eide so replacing it with a 180mm. It will be squueze to fit all in so useing 520 chain in stead of 530 to gain another 4 mm.

Nice clean frame to start with before mountings are added

This is a factory metal works frame. 5 degrees extra rake, 2 rise at front, 4" streach in rear with 3" drop at rear. Frame widened for larger rear wheel (although not enough)

XS650 hard tail frame with springer front end

Use the bottle bush and lightly hone both cylinders. Dont worry about what extra wear you are causing as it is minimal. Get a nice cross hatch and all will be good. You do not want a smoth cylinder as the rings will leach by.

I will measure today and come back to you

Yeh, mine is a 75 model so is the same as the tacho cable. Yours being a 77 may e different?

Good stuff Slug. It is good to see some one else out here building an xs. I see so many "cookie cutter" Harley choppers I at time doubt that anyone has originality. I hope to get up to the rod and bike show your way on the 30th of April ? For the Boogaloo at Castlemain. Only British or American...
