  1. Yep, I'm onto it here. Fitted a new set of points after getting the source coil rewound .
  2. I’ve been mucking around with the tuning on this but it’s still not pulling all the way through the revs. So I got carried away measuring port timing, squish gap, compression ratio etc: Lifted it onto a table to save the knees of my jeans: The results are interesting: 182deg of exhaust duration and 144deg of inlet/transfer duration according to my super accurate paper dial gauge. This means that I should be able to deck the top of the cylinder a bit to get my correct squish gap. I was worried that my 0.9mm adapter/spacer might have thrown the port timing out, which would mean decking the bottom of the cylinder instead. I’ve also recently learned about how to set ignition timing with points, so I’ll set the timing right while I'm there.
  3. It's actually me holding a puncture patch onto my original tube after running over a nail in @Firetruck's section. It went like this: Go see Yowzer Run over nail Say fuck Pull out nail Go home to get tube Replace tube and tyre Fuck new tube by going in dry with the tyre levers Go home to get other tube and puncture repair kit Replace tube again Fuck second new tube by going in dry Patch new tube poorly Won't hold air Patch original tube Refit tube and tyre with LUBE Refit wheel and drive home in the dark with almost no lights It was a hard day. lucky Yowzer and @64vauxhall had beer and @Beaver was keen to help with levering and lubing. For some reason this tag won't go away >>> I can't delete it or type after it. WTF @Truenotch i made my tag go away
  4. Hah! It's getting a muffler. Even the people at the gang house across the street were shaking their heads at me . After a week of fretting I figured out the reason it lost spark... It was because the flywheel magnets were touching the lighting stator. I knew it would be something simple! So the stator winding was probably never the main issue, but the dodgy part of the ignition source coil is fixed anyway. Stoked to get to the bottom of it! Threw in the biggest jet that @Raizer provided and went for a few hoons. It bogs massively at full throttle and doesn't pull up to high revs because of the rich mixture. Goes pretty well up to 3/4 throttle though. It sounds great when you blip the throttle! It's got this old dirtbike muffler temporarily. Seems to work well.
  5. Success!!! It’s definitely loud....
  6. Started refitting the engine: Mounted the spanny - the header is a bit long, but it’s as close as I could get without the kickstart hitting the spanny. Spot welded the broke headlight bracket back into place: And fitted W clips to stop the light flopping all over the show: It’s getting there! For some reason I can’t get spark out of it... I suspect the coil is toast - luckily I’ve got another one on the way. Hopefully it turns up early next week! I also don’t have a muffler yet... it might be loud for the first few runs .
  7. Yaaay, new parts day again! Bought a few bits to repair the slippy clutch. New frictions and intermediate plate. This beast has TWO WHOLE friction plates. Also bought a new actuator arm mechanism: At the same time I got a push rod, a ball bearing and a clutch cable. And a nice new clutch lever to replace my knobless one: Drained the oil and got started on disassembly: Lucky I did as I found the main kickstart circlip had lost its ends! This takes all the load when the Kickstart engages... I also got a new throttle cable and a set of points. I was able to make a hybrid of the old and new 2-1 cables to suit my new carb.... Things are lining up well for a weekend hoon? Albeit without a muffler on the spanny .
  8. Otherwise you might be able to steal @UTERUS‘s CT for the weekend?
  9. Same here - gizz deets. Also, @Archetype will need to sort out a bed for Saturday night if anyone needs a bunk buddy? My friend Richard will need somewhere to sleep too.
  10. @Kimjon - google Ken Cairns Electrical and his phone number will come up. He works out of his home garage in Dinsdale and is a good old dude.
  11. Yep. Covered everything in resin too. Champ.
  12. You’re a legend @Thphantum! Thanks. 2 stroke all the way!!! (Hopefully).
  13. Ignition winding rewound. Ken Cairns is great - he’s definitely getting on, but knows what’s up. This job was $30 . Missed a delivery from Yambits today... I’ll collect it tomorrow. It’s got points, clutch parts and a few other goodies to keep me busy.
  14. @MichaelJFox - Flick me a message and I'll put you in touch with someone else who's going to book a room.
  15. New head arrived today to suit the 45mm kit. It's a high comp head and has a huge amount more cooling area than the standard one.
  16. Me too! It's spiralled out of control, so it better go OK.
  17. Made this little adapter plate today. Hopefully I’ll be able to fit it up with the reed block tomorrow. Took the stator to an 87 year old man for repair. He’s going to fix it in a couple of days for $30. What a legend - he’s definitely on the right side of Barry valley.
  18. Especially since I just spent a whole $30 for this second hand jacket from the hospice shop. Friggen bargain mate.
  19. Just received a wedding invite in the mail.... For November 10th. FUCK SAKE. I guess the bride and groom will have to celebrate without me.
  20. Since the motor is on the bench I set about fitting the 45mm cylinder. First up I made a .9mm aluminium base gasket to deal with the overlap of the transfer ports. I think this will do the job. Bonded it on with CRC high temp rtv and will use the same again when fitting the cylinder. Alsi had to nip the corners off these cooling fins to get the cylinder to go all the way home. I’ve also figured out how to mount the carb - I’ll make an adapter plate to turn it 90 degrees so it pokes out the side like this:
  21. This was running pretty OK for a while until I tried to ride it to see a friend. It fired and ran once, then wouldn't start again. I reset the points and it fired up again... Once... Before deciding it didn't want to make spark anymore. I had a decent look around everything and the points and condenser seemed acceptable and I'm pretty sure the coil is OK. Then I noticed a dodgy looking of the ignition winding and gave it a poke. It broke in half and appears to have been soldered together at some stage. Hoping / am pretty sure this is where the spark ran away to. You can see little soldered bits on the end of the broken wires and the last few coils of the ignition winding are loose. I think someone bodged it up years ago to make it work. I'll take this to an electrical barry next week to see what he can do. I'm pretty sure this is the cause of my problems... But I'm not 100% sure. The wire looked dodgy before, but it wasn't broken. Only took a small bump to break the solder join though. I guess we'll find out if it was the main issue
  22. Got it running a bit better today. The clutch slips if you don't change really gently. It goes OK though!
  23. Yay, parts day! Unfortunately there's a bit of work needed to make everything work. I gambled on the Polini cylinder for the Chappy being correct because of some info that I'd found on the internet, but it turns out the Polini kit has HUGE transfer ports that are far too big for my crank case. This leaves gaping holes around the edges of some of the ports... So I'm stuck trying to find a solution. You can see the difference between Polini and standard ports here: My first option is to use JB weld / some type of compound to goo up the ports on the cylinder. I'd also add goo to the mating face on the crank case to get a good sealing surface. Then I can port match the cylinder from there. Option two.... Um.... A metal gasket or something? Not sure. I also need to modify the inlet to get the reed cage to fit. It needs a couple of MM taken off to fit nicely. I'll also need to modify the chappy inlet manifold to suit. I could either add a wedge underneath to get this angle or add to the manifold with an elbow / new tube. Once I realised nothing was going to work today, I set about trying to make it go as a 50cc again. It was a pretty mad mission and I was trying to finish it in time for the oldschool meet tonight, but it wasn't to be. I got it going afterwards though! Here's my temporary headlight until I sort the wiring out: Took it for a hoon. It's going much better than the last test, but still not well. It splutters a lot, although I did double up on oils (premixing incase the oil pump didn't work) and the carb enclosure was open, so it was likely running lean, causing the splutter. I just had to ride it to make sure the next lot of effort will be worth it! And it seems like it will be... The thing is quite peppy when it decides to pull through the revs.
