Re: Another tough day at the office !

The performance of the bike is fine although I now only dawdle around country lanes etc. at no more than say 45/50 mph.
It also maybe that because it is not too a finer mesh and not closeup to the bellmouth that there is sufficient variance
between theory and practice.

Re: Another tough day at the office !

The mesh used is 30 gauge which has an aperture size of 0.567 mm (.022 inch) so it will only filter out anything that is larger, therefore, it will not filter out dust particles as described. To use a finer mesh ie a smaller aperture size, it would require the filter to be much larger in size in ord...

Re: Another tough day at the office !

On the KH with the bell mouth removed there is approx. 32 mm clearance between the carb. and the oil tank just enough to a make one to fit, your experience has now prompted me to wire it on.

Re: Primary chaincase disaster

To lock the subject screw in place I drilled 2 small holes in the casing adjacent to the screw and wired it through the screw slot, see attached.

Re: Brake and clutch levers on kh

Firstly, I stand to be corrected, see my previous post, after having second thoughts I believe that the breather nut had a Cycle thread and not Whitworth. Regarding the timing side bush, my engine still has the original white metal lined bush, when stripped 2/3 years ago, it was in good condition, a...

Re: Brake and clutch levers on kh

Paul, I except your point that the 2 screws may not fall out but I was not willing to take that risk just for the drilling of some small holes and a piece of wire, if I remember correctly the screws were of a Whitworth form ie a course pitch, therefore often difficult to lock by torqing. I also fitt...

Re: Brake and clutch levers on kh

Also, a thought for the future, rebuilding my KH engine I found that the 2 small internal screws within th...

Re: Turning on a mandrel - Loctite?

Another method- . Ream the bush out first. . Fit the swinging arm spindle in the chuck, use 4 jaw if necessary to set spindle true. . Mount bush to the swinging arm spindle, clamp bush with the spindle thread and nut. . Turn o/d of bush. Regards, John P.
