Hi all. I am quite new here..
I am Fred, aged 71, pension since 6 years. Driving motorcycles since age 18.
I was a chief workshop in a big motorcycle company since 1973 and I still visit them monthly.
Last year I bought a new Skyteam 125 Ace of course full of faults, but I can solve all that.
Here in my house I have a small workshop with lots of machinse, tool and welding equipment.
All save and warmed.
Since 1978 I have several old timer mopeds: a Honda C310A 1965, a Honda SS50 1968, A Tomos 4L 1972 and a Yamaha FS1 1982.
All of them in mint condition,however I took the Yamaha apart to fit a new crankshaft and bearings. Still busy with that.
This winter I took the 125 Ace apart to fix it with faster parts because of the lack of speed.
I mounted a big bore kit, faster camshaft, cilinderhead with bigger valves, exhaust system. A bigger carb is waiting untill this set has done some braking-in miles.
Some time fore I changed the tires, brake pads and shoes, fixed the side way play on the rear fork, placed better rear shocks, changed the steering handle for alum clip-ons, better speedo and rev counter, programmable cdi etc
Now waiting for better weather to take it for test drives..
I will keep you informed.

Welcome @
Post up some pics. Sounds interesting.

Properly sorting one of these cheap Chinese bikes seems to take quite a lot of effort for a new bike but interested to see the end result.

Looks good Fred. Keep us posted on your progress.
The weather is too bad for testdriving so I took it to the parking place to warm uo the engine. It misfired at 5500rpm so I changed the adjustable CDI for the iriginal CDI. I"ll try agian
the next dry day.. I have this motorcycle parked in my livingroom next to my 4 old timer mopeds.. No rust

Looks great Fred! Excited to see the progress!
Just a sidekick. Motorcycle and 2 old timer mopeds here in the livingroom beside my pooltable, Two more mopeds in my small workshop, equiped with a lath, milling machine etc.
Still working on my Yamaha FS1, new bearings, crankshaft, oilseals and now waiting for a special tool to pull the new crankshaft in the left handed bearing because I don't like the idea of hammering on a new crankshaf

Changing the bearings on the FS1 was a piece of cake. The carterhalves one by one in the oven, monitoring the temperature with a infra red temp meter. At 140 degrees I could push the bearings out with manual force, The new bearings from the freezer I could push them in the carters without any problems. The hardest part is waiting for the special tool.
