One of my WNGs had a really annoying top end rattle, proper loud. Had it ages, tried a few things and was living with it. One of the local lads reckoned it might be the pushrods hanging up in the rockers. Yeah I thought . Well, after my issue with sticky push rods on my other single, I had a look. W...

Update. I swapped in a single lobe cam and followers. I finally traced fluctuating clearances to the push rods hanging up in the followers and, to a lesser extent, the rockers. ... very odd but cured with some lapping.

Thanks for the info everyone ! I've got it apart and....... can find nothing untoward :? .

Doesnt get better or worse when hot and unchanged in the first 50 odd miles, despite altering the clearances timing and other obvious stuff. It sounds like ...

High quality tap and custom made lanyard.

Dunno really ...found the twin revvy ..... I like the rhythm of the single.

Odd though, as I proper love my t140v .

£20 for the rusty frame at a jumble. 8 months to get it re-covered .. but I'm pleased. I could have bought a swingarm to house my girl comfortably ... but I couldnt sell my plunger twin. So it's now got a 500 single, my preferred engine, and a comfy seat https://owensmotorcycles.co.uk/images/spares/...
