Yep, mine had become yellow and hard where they fit onto the rockers, but were quite soft further down, hence the kinks which were restricting the pipes a little. I have seen that pipe with the green hue - guess it really does not matter what you use as long as there are no restrictions. Crankcase b...

Just replaced the ones on mine with some decent thick walled pipe that does not kink. Guess the ones that were fitted were the OE ones - clear plastic ? I replaced them because where the PO had used cable ties to stop the pipes flapping around they had become restricted, which is probably not good f...

I took a look at Kings of Pistons, looks like they do "printed" pistons for 350's - only £850 or therabouts each !!!

Guess they are 3D printed.

Not really going to know what I need until I take the top end off over winter.

For what it's worth, it looks like this company https://www.coxandturner.co.uk/piston-rings/ can probably make / supply piston rings, but not pistons. Might be helpful if someone is looking for a set of rings. No going to be taking mine down until the winter months so will not know exactly what I ne...

Needles are up for richer, down for leaner.

Pre empting that my 3 1/2 might need a rebore or at least new rings, I will find out during the winter months. Although it starts / runs / ticks over just fine, there has to be some reason for it's lack of compression. It has started to burn a little oil on the front pot so could be bores / rings. I...

Well I never did remove the starter, decided it was too useful so bought a new battery - Yuasa YT12B-BS which is good enough ? Roll on a few months, it has decided it no longer wants to start on the leccy start. It still starts first or second kick, but flatly refuses to fire on the starter. A few w...

Things have changed over the years, whether by necessity or circumstance. Back in the early 70's my sole transport was a Triumph Tiger 750, never missed a beat, loved that bike. As the years have passed motorcycles have become a hobby for me, although I still go out in all winds and weathers, but on...

I have a few road tests in a book called Moto Morini 3 1/2 & 500 Performance Portfolio 1974-1984, think that has some RPM / MPH values in it.

I'll take a look.

Funnily enough I was talking to a motorcycle speed cop a while ago, and said to him that speed limits should be interpreted as a limit and not a target, to which his reply was "right answer"

As my bike has a KM/H speedo fitted I fitted a cheap bicycle GPS speedo to it as I hate constantly trying to multiply the reading on the speedo by 0.6 to know how many MPH I am doing in in theory.......... The Veglia speedo is actually out: Veglia 110K = GPS 60 MPH (Should be 68 MPH) Veglia 100 K = ...

I am hoping to give up w**k in the next 18 months or so, as I reach retirement age next April.

Youngsters dont have the interest in bikes that they had in my day, guess things change.

Think you are right about the 80s / 90s / 2000s bikes, interest in old Brits is fast dissapearing.

Jen thanks for that. I was just wondering as where I live in Somerset, you very rarely see "classic" bikes being ridden at all these days, except when there is an organised ride out of some kind, I think that people are loosing initerest in "classic" bikes, the market is certainl...

Soon be a year since acquiring my Morini - my first ever one, and it is certainly living up to the reputation. I have done getting on for 2000 miles in that time as it is a fair weather bike. Took me a while to get used to reving it like a 2 stroke, and the RH gear lever / LH brake. Just wondering d...

Guess that would make sense, possibly why the old seal was leaking.

Good news is that it roughly 1/4 of a turn away from fully tightened no signs of an oil leak in about 300 miles.
