I managed to hole the piston going flat out up hill tonight. All the classic symptoms. I'm already thinking about the new one. I've yet to get the motor apart (as the scoots in a mates shed at the mo) and I'm interested in some opinions as to what the best "non-packing plate" solutions are out there.
It's my first TS1 and I'm looking to be pointed in the right direction. What's been used and deemed suitable a suitable replacement without breaking the bank?
Thanks in advance.
Easy (non exotic) TS1 Replacement piston
std piston or race tour imho

And make sure you find out why it holed (mix, squish, timing,comp ratio, air leak etc etc) and fix the problem. Dont just 'fit n ride'.

I'm thinking it was a combination of factors.
I was running a little lean on the mix. In the 3% area but not lower. I was killing my last bottle of Mobile 1 before switching over to Motul 800 and came up a wee under 4%. I don't run an air filter on the mikuni. that could factor in. I was going flat out, full tuck, passing18 wheel lorries at about 70mph ish.... up a steep hill with less than a half of standard bretta tank of gas. Fuel starvation could be a factor.
I'd been really wringing it's neck for about 8 miles before heading up that steep incline. I could be wrong, but I feel (no proof) that it was hot and lean.
Oh well.. live an learn.
But yeah.. deffo not a 'fit n ride' piston job. It'll get sorted right. I've got a club mate that's pretty ace with all two wheeled machines. He's something of a moped whisperer.
