Day by day I am gathering my small beast to ride able condition. Unfortunately I can not do a full restoration of it as someone does it and show it at forum. I decided just gather it in stock condition using old but proper parts.
For now I have two main problems.
First is the crack on the exhaust port of one cylinder.
Second is one of CDI unit is not working.
The first problem I solved by buying the set cylinder+piston from Japan. I really hope that it will be in a god condition. The photos on the Yahoo could be much better but I have to take it for luck. It quite expensive but re-plating much more. An addition, in Russia no one do this work.
The second problem have appeared when I checked wiring and discovered that I do not have one spark. I rechecked all wires fixed all old crap that was done by previous owner. But one spark is not come back. The engine starts quite quickly but working only one cylinder. I checked pickup coils, ignition coils, caps and high tension wires. All things show a good condition. Today I am going to swap CDI units and watch if be working other cylinder.
When I be sure that the CDI unit is dead I have four option.
1. I open dead unit and bring it to a man who understand how to fix it. I am nor sure that CDI unit can be fixed. But I see in internet the lot of them were opened and fixed. Is anyone have the circuit of it?
2. I buy used units on Yahoo. (not sure that it will be working). It is quite expensive and I have to wait for month.
3. I buy the china one on Ali. It is really expensive for me and the same month waiting.
4. In my city I can by CDI unit from mc 18. It is quit cheap. But I am afraid that the mc18 unit can require to change flywheel, pickup coils, exhaust valve control units and add a throttle sensor. I can do all of this things but I do not know If it is a benefit in using the mc18 cdi unit on the mc16 engine. And It controverts to my thoughts about keeping the bike in stock condition.
My appology for my English.
