Been busy preparing my racebike recently, but i managed to make a start on the savage chop build today. First part to make was the headstock tube or 'neck' and it's the first part of ... many!

The blank tube is 60mm OD 5mm wall, Cold drawn seamless. Made it to use the existing taper roller bearings, so pressed in an insert at one end for the smaller OD top bearing.

The choice of available belts give me 2 options, 4.5" longer or 6.5" longer. Height is easy, low .. really low

I would be careful of really low,one of the biggest problems with most of the hardtail kits is the fact that they are designed to low ,the Ryca doesn't allow you the choice of running the exhaust pipe down in the normal position,and the VV kit forces you run a larger rim and tire to get minimal ground clearance .If your frame has even a bit more than stock neck angle ,things can become even worse.5 inches of ground clearance isn't going to look bad on a longer wheel base , and will make the bike a lot easier on footpeg wear.

Thanks for the advice Batman, i chose the ground clearance by taking measurements off the standard frame at the very bottom of front and rear suspension travel. I've set the jig to that height, which gives 4 inches of clearance, but i've no idea how that compares to the kits that are available.
I do want to keep the exhaust downpipe running down under the engine, and i've not committed to any design yet so i could add an inch without any bother. I'll stare at it some more before settling on the final dimensions.
Oh, and steering angle will probably remain at 35 degrees.

Thanks again Batman. I've decided to add an inch rideheight at the front after your last post, i wanted to allow for any sag in the forks and to allow a bit for the travel when braking. I thought it best to do that now as it's easy to shorten the forks afterwards if it sits too high.
Been using photoshop to alter things like the steering angle but it's doesn't look right when it's steeper. I'm now just totally undecided between 4 inch loner wheelbase or 6. Actually the belts give 4in or 8in but i can sit the engine 2inch forward and stretch the frame by 6 to effectively make the 8in.

Re: New bike, New member, New forum, New project Reply #36 - 03/29/17 at 16:13:14 Why not pick up a parts bike ? Ride this one, work on a frame, get the mods done, if the engine is repairable, use it, whatever, but it's not looking like dad's gonna be riding for a while if you guys start down that road without more than just the one bike.

The key issue is can you live w/out it when you need it.
RYCA has a foot operated lever and a thumb lever.
Foot lever instead of shifter that can be operated anytime.
Thumb lever needs the clutch safety disabled or other means
cause you need your clutch hand to flip the lever.
which would be a PIA if you're trying to push start.
Or restart on the roll.
