The Black Bomber Board / 71 CB450K4 float levels
« on: February 09, 2020, 06:24:12 PM »
I have my 450 running, which is surprising as it was seized when I got it, but not very well.
New plugs, points, condensers, nice bright blue spark at the right time.
Carbs are spotless, all primaries etc cleaned out, and rebuild kits inc floats.
The bike is difficult to start, will run nicely at highish revs, but as it settles to tickover it dies, seems to need air which leaves me thinking its float heights.....

Can someone confirm is it 20mm to the gasket face or to the body flange?? I have them set to gasket face, which seemed the most common advice, but looking at the card tools they must set it to body flange, which is a 2mm difference.....

The Black Bomber Board / Alternator rotor puller.
« on: December 01, 2019, 03:04:48 PM »
Hi all,

I just returned to Classic Honda ownership, after selling off my sohc 750s and parts a few years ago.

I have. 1971 450, and just looking to remove the alternator rotor, is the puller needed anything more than an M16 screw with a fine thread draw bolt up the middle?? If so I’ll just make one up, and a protector disc for the bolt to push on and protect the crank.

Cheers.

Thanks for trying though.

I thought all sohc were 14mm spindles, the dohc went to 16mm, I have modified a dohc to fit my K1, it uses needle rollers, was wider and longer than the K.

Does anyone know of a maker / supplier of 4-2 exhausts. I’m using a 392 engine in a 71 chassis, so would need K6/7 exhausts.

Ive a few sets of headers, 4-4 and 4-1 so could make my own, but re chroming would be as much as aftermarket pipes.

CB750 / Re: Source for Cam Chain Tensioner Spring at resonable Price

I prefer the manual adjuster conversion, the spring only sets the initial tension, then its locked up with the pinch bolt anyway.

Cant find any references, but do the dots on the 392 pistons go to the front of the engine?.

Cheers.

From an engineering viewpoint studs are a better solution, less chance of stripping the threads in the alloy head.

It could be someone has stripped one or more, and put studs in to reach undamaged threads deeper in the hole..

It could work, but, you would weaken the bearing housing by machining off the overlap, you would also need to use a sealed bearing.
What bout chain run? Have you checked that would be straight.
I think I would try a matching Kawasaki hub before machining the Honda one.
