FWIW I've got 2 TV175S3's- one has a Muggy V1 with a 22mm carb and a 42 mm Clubman. The second is totally bog standard apart from a 42mm Clubman, and a bit of home brew porting work (matching and polishing; exhaust raised by about 2mm and widened a fraction. A new piston (Mahle £30ish) and rebore.

Guess which one I prefer? The standard one. Just been round the block on it and it will hold a true 65 for as long as I like. The TV175S3 was Innocentis flagship until TV200 came along, but in my book its a much nicer scooter to ride.

No problem Dave and you've got PM.

I know what you mean by not spoiling a lovely scooter- you just want it a tad "crisper".

I've also got an totally original LI150 Special which will remain untouched for as long as I've got it. All I've done is remove the top end and carefully store it away, and have replaced it with a TV175 cylinder bored to 64mm (186) and an appropriate head- I've even retained the original SH18 carb on original jets etc. Now gives me safer performance in todays traffic with original looks. Absolutely no problems with starting and reliability.

If I ever sell it, its an easy job to return it to factory originality.
