Took head off after breakdown
-
@Calum thinking about build it up again and give it to someone to check and tune it properly as Im lost confidence haha .

@Zrako Not really mate. It's so simple and we are here to help.
Literally it's the crank seals. Yoy gotta imagine that when the bearings went they would have gone for the softest part of the engine, whih is the seals.
@Calum yeah , didnt thought about it as I think I checked them , silly mistake. Do you think I will need a new head gasket ? Im did the light skim as you made the tutorial for it , dont know how to identify if the head gasket is bad or reuseable...

Well , here we go again . 2nd rebuild . Now with new crank bearings and seals
, new piston and rings , new - used clutch , removed kickstart and got new used stay for the sprag clutch and installed starter motor, fresh gear oil.Here is what it sounds like . First start was surprisingly smooth ,was idling bit higher so turned it down and bled autolube . Feel strange as it was maybe too good to be true lol .
Let me know what you think about the sound. Havent jump on it yet btw.1979 Jawa Mustang 50

Google my friend.

Wow I have never actually read this up before. Always assumed a "plug chop" was running the bike for couple minutes, then visually inspecting the plug. Seems like a lot of effort / plug money to get it running perfect, but obviously worth it. Nothing better than a 2 stroke motor purring over perfectly.
-
@Mightyman and you know what they say about assumptions.
Oh my bad, seriously I thought it was common knowledge.

Completed the bike again 100% , 10 minutes warm up , took it on the street . Hardly powerband , valve moving properly but struggled . Tried to go between the gears hardly 3rd only sometimes . Impossible to shift , only with heel
. Took it apart again and tried to figure out whats going on. I think this is the problem.I think the sping is slacked. Found picture in the haynes
Did anyone experienced something like this?
-
My spring doesnt come up through the holes like yours does, the legs sit underneath the same as it does in the Haynes manual image
-
I dont think you need a new spring you need to push the feet of the spring back through, the spring is pretty slack on all ive seen but not had any gear selection problems
