at least I hope so, as I've not touched this end of the selector shaft

I've just measured the mec-eur outer and that's 44 inches exactly, which is the same as the Scootopia. a tad shorter than the cable you measured
It's not the end of the world with the outer being slightly too short. With a liberal amount of grease on the inner, it should be fine-ish
However the too tight a radius then ideal at the wheel, must be putting additional strain on the speedo drive gear, and contribute to premature failure

In the end the speedo cable was OK, I just bent/eased the plastic shroud into the same curve as the cable, and everything was well
I also picked up a nice inner legshield spare wheel holder.
pleased with with the overall result, and roll on warmer days/evenings

I’m fortunate in that Ron Moss had previously tuned the barrel fitted to the SX. I’m not into port timings and all that ‘malarkey’ so I’m assuming the barrel has a basic ‘60’s tune’
Speaking with Stu Owen who has helpfully supplied his SX setup I’m going to attempt to replicate his machine. Incidentally my SX here was also owned by Stu Owen.
My constraint is I’m just using what I already own, in the garage.
So it’s on with a large volume airbox, Scootopia clubman, and a Dellorto SH2/22
I’ve already broken my rule as my good friend Alex has swapped me the carb for a rack I owned.
The gearing is per my GT at 5.0
I already know this won’t work following a short test ride. I’ve read a number of posts here regarding tuned SX150 gearing and have decided to revert to the original gearbox
Stu was running pacemaker and sprockets to achieve 5.3. I don’t want to spend ££ so it’s SX150
I already own a nice Li150 gearbox and the sprockets to achieve 5.3 if required. Eg the SX is too revvy.
At the moment I’m waiting on a clutch spider shim of 0.3mm before proceeding.
No pictures at the moment as I’m on my phone, in a B&B attending the IoW rally
Laters…

I changed to a low to mid rpm expansion and it was dire. Swapped gearbox for LI150 and it was cured.
The GP150 or SX150 gearbox is awful for anything other than standard motor. Old story but needs repeating every now and then.
