Worst bike- any bike I have that breaks.
I get so humpy with them. Storm's dropped CCT's twice now, so it's heading up the list.
mind you, I thrash it everywhere and use it eveery day, all weathers, so to be fair....
Bets buke?
A whole load of Honda CB125's, I sued to buy a couple of spare engines and swap tehm out once I'd wrecked them, usually by siezing or burning a hole in the piston.
I'd been banned a few times ( never mind what for) and these were cheap to insure.
Fitted straight-through pipe, 42m speedway air filter worm-clipped down to the 22mm carb, lots of rejetting (even had an Amal on one) and altering timing, high-compression piston (1/4 of a 500/4 kit- Parks in Lewisham used to break kits for me as I was there so often!
Lots of fettling, workshop time and seat-of-your-pants tuning and with a fair wind downhill they made about 70.
Still, got me to TT once, and loads of furthest-travelled awards at rallies, which was a laugh. Mad Sunday was a riot

It's not falling off, it's an upgrade opportunity.
