Tony & Brenton, Thanks for quick response. There was no sudden slowing down of the bike although the engine cut out briefly. Rings are fine. The clattering noise remained after the onset. Took bike home, started her up again and although she ran smoothly, the clattering remained. Checked little ...

1957 VH - Piston Slap, new piston & rebore?

Re: How do I add a photo...?

I have tried to add an avatar. I resized the picture to 100 x 100 pixels but the system refused to accept it saying "file bigger than 6KiB. I reduced the size to try to get it within that limit but the result was a smudge. Any ideas?

Standard or High compression piston?

Hello All, I am doing an overhaul on my 1957 VH500. I have just set the timing using the 5/8" BTDC. BUT, I have just noted that it is 1/2" for a 'Standard compression' piston. I have read the various items from AOMCC website and my piston does not fit any of the decriptions. It has the mar...
