Answer 1

For general parts take a look here:

For your kits, try here:

I may have some other websites that I've dealt with in the past but these should get you started.

1976 Honda CB 750 K6 < my favorite bike that that I ever had. Should've kept it.

Answer 2

Please listen to this before you waste your money. Unless your running over a 572 hydraulic cam GM motor You will over gas it and kill your low end torque. Pick yo a copy af th elatest 2007 GM performance hand book at your Chevrolet parts counter. The part number is 19170580. It will be the best $5.00 you will ever spend. There's a ton of tech stuff on recommended carbs. on different cubic inch motors. The only application over a 750 cfm Holley is the 1090 cfm. mechanical secondary Holley used on the 572 cubic inch 720 hp big block. If you insist Summit has an abundance of carburators, throttle plater and main body's. Good luck.

hondaservice.com or servicehonda.com I can't remember which is correct. They got everything for old bikes. Use their phone # off the site. It's the easiest way.
