Not sure of flow testing results, but from the videos I've seen of this cylinder in action before he went water cooled I'm very confident that it works at least haha This runs Suzuki CCI lubrication, so the left bearing is fed oil directly from the pump before it makes it's way into the conrod bearing, seems like a good system to me, just no option to run premix. Speaking of porting though   |

All new genuine bearings, seals, gaskets, shims and spacers etc went in. Got it all together and tried the gears while spinning the input shaft, found I've got a box of grinding sounds, 2 gears, 3 false neutrals and it loves to lock up.
Think I've found the "noisy clutch" now!
Thankfully I've got a couple spare engines now, so am going to swap another shift drum and forks etc in and hope I don't destroy any bearings or anything while I'm at it!

Now I see what's meant by angling the inlet port. Cylinder liner doesn't get in the way?

It's not too bad, but I may be able to trim that corner of the liner to open it up a touch more.

Pulled the trimmed intake disc out of my original engine and fitted it along with a new drive gear, pin and key etc
Soaked the new clutch plates overnight, then installed along with new clutch push rods and pressure plates etc
New genuine springs are slightly shorter and a bit heavier gauge than the originals, bonus!

You're probably sick of updates on this stupid little bike, but here's another lol
Oil feed into the engine was blocked by the sleeve for the new intake but the new Dellorto carb has an inlet for 2t oil, so I cut the factory one way valve/banjo fitting off the factory hard plastic oil line and managed to adapt a fitting off a Zip oil pump into a hose joiner.
Took a fair bit of mucking about to get it into the old Suzuki line, but I got there.
That white fitting is a one way valve from a late model Suzuki, going to run it inline same as on a Let's 2/Yamaha Jog etc.
Finally got the flywheel sorted, drilled out the rivets from the factory A50 flywheel, bored out the new one to fit over the back of the A50 hub and got it timed up perfect, I hope.
Not planning on running those 3 M5 bolts, either going to go with 6x m6 + Loctite + hope or I think there's a Vespa shop up in Auckland with 6mm rivets in stock.
Original builder of this set up had the flywheel outside the hub and ran it up to 15,000RPM with just 3 low grade M6 bolts, so I think either option should wok out TBH.
Just need to mill/grind 3mm off the pick up mount and it'll be perfect
Just need to get a couple O-Rings for the carb and pull the seat and tank off to change the coil + wire up the CDI and change to 12v bulbs all around etc.

Have gone with the 6 bolts + Loctite and hope plan
Trimmed up the pick up mount, got it pretty well lined up now Few MM clearance should be plenty
Bit more blasting
And painting
Just a tad bigger lol
Used some copper headgasket spray on the combustion chamber insert and some PC thermal compound between it and the head cover and I think it's pretty much time to do some wiring, sort out the exhaust and give it a kick!
Air filter might be a good idea too

Anxious to hear if you have a good sparking iggy as reversing rotation can be a bit tricky..

Anxious to hear if you have a good sparking iggy as reversing rotation can be a bit tricky.. I've got my fingers crossed! But I am also quietly confident it'll work as I've seen videos of this exact set up running well on another bike, he's gone to a tiny inner rotor set up and water cooled top end on the build my parts came off. Just working on the wiring now, trying to keep it almost stock looking where possible. |

Just working on the wiring now, trying to keep it almost stock looking where possible. Started with the stock wiring, which I was never too happy with
Made a small loom to add a reg/rect and CDI into the existing wiring
This was before everything was trimmed to length and taped up
Bodged up a piece to adapt a good quality new coil to the original mount, it's hidden way inside the frame so doesn't have to be pretty
Made up a mount for the CDI and got everything installed, I think it's come out pretty decent!|  The red and black wires are to connect to the battery, planning on running a LiFePo4 in it
Out with the old
And in with the new
Airbox is purely decorative now, need to turn it into a storage space I think
Just need to make a choke cable, exhaust, paint a few bits, swap in 12v bulbs and horn and put it back together

Not much of an update, but an update all the same. Made a choke cable from bits from the bike shop and solder on ends from a local motorbike shop, have ended up with fancy Teflon lined Shimano outer cable, it's now the smoothest cable on the bike haha A mate hooked me up with a sharp deal on a LiFePO4 battery and some gauge bulbs from his work and after grabbing indicator bulbs I had the last bits for the 12v conversion  Major overkill considering that I don't have electric start or anything high load, but it's small.
 The chain guard/sprocket cover from the new engine is a different design from my original that actually covers the whole top of the chain which I like, so I wrinkle painted it and then discovered it didn't line up with my original clutch cover  Bit more painting and baking   The pad for the gear shift pattern sticker is annoying, but oh well. Finally got sent up the exhaust nut I'd been waiting on   Going to have a play with the Stage6 ProRep that's been hanging in my shed for a few years I think   Thinking external stinger to keep length down.  |
