i like the frame jig. i bet that makes the build alot easier.
If you can't modify it why have it???

Frame jig works well!! We have got the swinger on at the moment to align the sprockets. We have engine mounts made, rear sprocket made. Just got to fab the top rails, exhaust (twin Akrapovic cans)!!!

few more pics. Swinger on, sprockets aligned, lower rails done...

Anyone got any idea for uprating the brakes? Will wavey disks and good pads be enough???!!!

the stock fronts is probably your only option. but, for the rear i would try and put a bigger street bike caliper and rotor to help rein in all that extra weight.

A more powerful rear brake without a much stronger front would not be the hottest idea.Originally posted by jcs003

The rule is that about 75-85% of your braking power comes from the front because as you brake, all of the vehicle's weight transfers to the front end. An overly powerful rear brake will make the rear more likely to lock up and swap ends.
I would actually recommend larger diameter front wheels (and wider front tires, for that matter) and see about a larger diameter rotor and/or upgrading the front calipers.
That is, if this is going to be run on the street. If it's going to be just a dragster, then forget all this because it usually doesn't matter.
