CB750 / sprockets
« on: August 27, 2011, 10:25:52 AM »
Hi I have just bought a CB750 engine and a pair of wheels, the engine sprocket has got 15 teeth, and the rear wheel sprocket has 40 teeth, and both sprockets are very thick, a standard chain wont fit. the rear wheel sprocket has a label on it (azusa engineering) my question is what was this bike being used for. and why were these sprockets fitted.

Misc / Open / hailwood replica
« on: April 02, 2011, 06:07:09 PM »
when i have finished my CB750 F1, i am thinking of building a hailwood replica 500 4, A few years ago, there was a series of articals in motorcycle mechanics that ran over about 6 issues, i think it was about 9 or 10 years ago, does any one still have them by any chance?i have emailed the publishers about them but have had no responce. failing that has any one out there done one.or have any info on where i can get info for the build, things like which front hub did it use, ie gremica or fontana or was it a honda.hope someone can help cheers Tony

Tricks & Tips / caliper piston
« on: March 09, 2011, 05:12:43 PM »
removed the front caliper off my F1 today, the bike has been stood for the last 10 years, so i knew it was going to be fun. The way i managed, in the end, to remove the piston was, I fitted the short copper feed pipe, to the caliper, and then fitted my tyre foot pump to the other end of the pipe, it just pushes into the end of the pump, and clip the lever down to make a tight fit, then i pumped the presure up to 60 psi and heated the caliper with a butane torch, and pop it came out,(at speed) make sure you arn't in the line of fire. but it worked a treat.

Hi Pete, thanks for the reply, the bike has been stripped, blasted and powder coated, cant start the rebuild yet as i am pushed for room. i have got my Cobra kit car up for sale this year, so when thats gone i will start the rebuild. it will give me a bit more room.
