Finał assembly. There's big washer on top of pressure plate missing, and still need to slap it in to the motor for final adjustment. Took me 40 minutes for tapping, cutting and sanding. It is really easy and straightforward. With half of the pads it grabs like crazy.
Update:
Got new throttle cable, wich is much shorter than the one from set. Throttle response is fast and smooth right now. Got some ignition timing issues, so I readjusted magnet on woodruff key. There is still some issues with jetting, but now I have whole set of jets to find sweetspot...
No words needed. She's a runner.
So I got her running, made two trips for about 20 minutes each. My first thoughts are good, but we got some teething problems.
She's to lean. No crazy lean, but plusg is grayish and she's bogging at 40 kph. No air filter doesn't help either. New jets are on their...
Nice progress there. SKFs found their new home. Cases are closed again. Used some RTV on cases and intake for better sealment. Exhaust is shortened a bit and has holes drilled for better flow. Head is on its place, and hole engine sits in the frame. I found better steering handle wich gives more...
Cylinder ports are done. Started with stone on my dremel tool, then sanded with 80, 120, 240 then water and 320, 600, 800, 1000, 1500, 2500. Need to hit it with polishing compound and dremel again. Sanding block from sushi stick 🤣🤣
I had same problem with my rear sprocket and Nexus 3 hub. Filed down inside bore few mm, and it fits like a glove. Check in my thread, there's a picture of how it look after filing.
Good luck and take care.
Polishing complete. Next is exhaust and intake ports, to remove castings. Exhaust will be polished as good as possible. Intake will be smoothed out but without mirror finish.
After hole cylinder package is done, next will be transfers. Need to open up them slightly, instal everything and check...
Hi guys, long time no see. After quite hard 2 years for me, it is time to continue my project. Sadly, I need to spend time replacing my old China Doll for new one. This time I'm going to make engine as good as possible, before first crank up. I bought new unit, wich is much better made than the...
It wouldnt. I need to enlarge the hole. Because coster brake arm is attached to brake cover, you need to take it out first, install sprocket and put the brake cover back on. Not too much fuss. Sprocker has lots of meat, so rebore it few mills to larger diameter wont make it any weaker.
Today started at mounting front fender. I dont even have vice, so it is all crafting. Drilled a hole in fender and screw the mount to it. Then started to bend it. You can see I ve got decison to made to hide it in the fork or make it visible more. And some photo art stuff
