I tried bigger jets without clear improvement. The timing seems to be little bit different from the original setting. I need to test different positions....

Last news:
- I adjust the timing and tested with a timing light: engine is running smoothly with less vibrations but still under 5000 rpm
- Remove the silencer, no improvement.
- Compression test by 91F is 155 psi (engine still hot).
- I am suspecting a wrong position from the disc:
I am still looking, ....

Done today: disc is well mounted.
I need to go ahead, any idea ?
Coil could be wrong only at high rpm ?

Finally the exhaust was clogged, after this I change the front sprocket for the original value 14 teeth (I had a 15).
I know reach 60 mph (confirmed by GPS). The vibrations are quite high, and carburetion needs to be finalised.
In the same time I found a bottom part from the engine at fair price on EBAY. The old lady will be ready soon

Last news: My idle speed in hot condition was very high, I replaced the exhaust seal and the trouble is solve.
The oil pump was not working properly (leaking), I replaced it with a cheap Ebay purchase, trouble solve.
The vibrations seems to higher than expected, such engine 2 strokes have always some issue. I have the original
piston and cylinder: I will test with them...
To finalize the rebuilt is taking some time, however this bike is funny to use: light and enough powerful for open road.

After 1000 miles, the bike reach 65mph (GPS reading), still few vibrations in the feet but I am live with them ...
I am using the Lucas semi synthetic lube oil: I miss the smoke and smell from the old oil .
I will start soon to rebuilt a 1975 250GT Suzuki but using daily my 175KE...

Hello
Last new, I renew the crankshaft, the vibrations are now low...
I replace my tail light with a 12 volt type.
I used a convertisseur 6/12 volts DC.
Waterproof Universal Vehicles 6V To 12V Step Up Converter Boost Regulator Module | eBay
I solve also my idling speed with a new turning from my air screw.
So glad to have this bike .
