Re: megacycle 541x4 degree options

Trimming the edges of the valves, chamfering them on their top edge (intake), and cutting them deeper will work. Also, make sure the intake valve is not hitting the edge of the fire ring (top of cylinder liner), as this will make the same clicking noise. If so, the fire ring can be chamfered slightl...

Add about 20mm to the length of each brake arm. As long as your drum is well fitted to the shoes, you will then be able to lock up the front wheel easily. You may also need to find or make a new front brake cable with heavier inside cable and better outside sheath. I used an old S*zuki front brake c...

Re: megacycle 541x4 degree options

Start by getting the mixture correct, around 12 to 14 is fine. If it is a little rich, it won't hurt, but try not to go over 14. Set the ignition timing at around 32-34 degrees. Just for starters, I would make the exhaust pipe quite short, around 23", and then make some 2" extensions you can try up ...

Re: megacycle 541x4 degree options

With flat followers, the valves will hit each other, as the effect of the flat tappet is to open the valve sooner and close it later. But you can get Megacycle to grind the tappets at 1-1/8" radii which will give you more duration and overlap, but measure very carefully for valve interference. Some ...

You mentioned that you had welded up part of the combustion chamber and that you have a squish band of .7-.73mm (about .028"), I am surprised that with the 92mm bore that your compression is only 10.5 to 1. So the top of your piston must be chopped or your valve clearances to the piston are quite la...

With the B44, you don't need the breather spigot, but make sure the inspection covers are vented type (they have small holes in them) to allow for expansion of the air inside. The B50 had unvented inspection covers. Beautiful job! Is the swingarm custom made or aftermarket? What is the muffler? Tom

Very nice looking bike. I would be interested in your combustion chamber modifications as well as rocker arms and valve angles.

I note you do not have a seat in place. A Matchless G50 seat looks nice on a race bike, if you don't have one yet.
