Parts for the V50 came in. DR 102cc, 18/67 Primary, full engine overhaul. Engine bushings were a PITA. Had to machine a "dilator" to help the tube go into them, using my hydraulic press. Most shops here retrofit the PK ones but then I would need to machine a "compressor" tube to make them go in...

Everything's clean and assembly has begun...
last time i did it i just hit it with a rubber hammer but ur smallie gonna be nice and clean Brother Safis:D

Tonight i manage to fix my smallie, test ride and maybe sleep well for the rest of the night

I was just accelerating away from a stop sign on my way to the train on Monday morning. Smooths street, 25 MPH speed limit. It got run pretty hard over the weekend, though. We might have done some aggressive comparative test rides over the weekend down at Malaprop Motors..

Hah! I think I'd definitely be the winner & all time champion of the "what's the craziest thing you've JD Welded?" contest if I pulled that off.

Just NO! This is a case where JB Weld would be bodging it. Send it to me or maybe qascooter so it can be dealt with properly by REAL welding! Then just use your favorite tool to finish and fit it .

The new axle and cruciform should arrive on Friday, assuming UPS keeps to the estimated delivery date.

The old axle is still stuck in the case due to me being unable to get the hub nut off. All I tried was hitting it with the impact wrench again after soaking with PB Blaster, but it's still irritating.

Tomorrow I'll try again using heat along with PB Blaster, followed by picking up a breaker bar if that fails.

I got the hub nut off and the axle out today while taking a break from making powerpoint slides, with a little help from my good friend Mr. Angle Grinder.

That axle clearly led a hard life.

If your whole transmission was still LML, that could have been your problem. Nevertheless, that damage is pretty darn impressive! I ended up upgrading one of my Stellaís transmissions to actual piaggio EFL gears.

Impressive! Same thing happened to Subetherbass' VBC original driveshaft (apart from actually breaking).

The driveshaft was not original. I'm not sure who made it.

1st and 2nd gears are original LML and pretty worn, but I went ahead and buttoned the whole thing up and got it rolling again.

Then, I moved on to the Sprint motor. I ordered a new castle nut tool (mine was pretty thrashed) along with a SIP deep castle nut and that thing went on almost as easily as a hex head bolt.

Then, I buttoned everything back up, went to torque the head nuts, and every single one of the damn things stripped out at 16 ft-lbs. Grrrr....

Ordered some M7 time-serts and will get it all sorted back out when they arrive, either later today or tomorrow.

In the meantime, I've decided (with a little prompting from my wife) that I'm going to reduce the size of my scooter stable to just the Sprint & GL. I'm going to convert my spare LML motor back to autolube and put it in the Stella with the 166 on it.

The VBB will get its original motor back, which was running just fine when I pulled it out, it was just slow.

The Sprint motor will go into the GL, which I'm going to do a patina frame and paint the new cowls since they have to be replaced anyway. I'll just need to sort out suspension, rebuild the front fork, and run cables & wiring/lights. sorting out a tank for autolube will be the most challenging part of that project, I expect.

So I have my next few rounds of scooter projects laid out, I just need to execute on them.

I don't understand why you would put a castle nut back in? You have enough build experience... that surprised me CM! Unless you had to wait a week for a good one?

M7 nuts/studs have a much lower torque figure than that! 13 seems to be the maximum according to a few sources. I normally only do my 200 M8 studs to 15.
Having said that, I've been guilty of stripping the studs before, most recently in the LML case with the BGM 177. I re-tapped to M8 and put 200 studs in there (worked out because I put a 200 crank in and was using a packer anyway). But I have seen them taken out to M10 with a stud turned down.

A while back, I installed 4 time-serts in my lammy because one of the threaded holes for the head stud was compromised. You just have to make extra sure to get those inserts perfectly square. Donít want to get get the head studs winging out every which way like Tom Bakerís teeth.

Six-spring clutch. I'm still on the hunt for a flange nut that will fit it and had the SIP order coming anyway so I tried it out of morbid curiosity.

I could probably go the M8/P200 stud route, but am going to go with the TimeSerts for now.

I've always torqued my tuned motors to 16 ft-lbs. Never had an issue before, including on this one.

Oh, well...

Im hoping to learn something here, What would one use if not a castle nut ? stock crank or aftermarket ?

Replaced the center mat on the rally. The old one was not falling off but was badly cracked and worried that water would find its way in.

I finally sourced an original battery cap for a GS160. This is a stupid latching system, but you know how it goes. Gotta go original.

You may notice that the tray itself is completed with some aluminum stock. I had to do that because the steel had been eaten away. I'll weld in a replacement someday.
