Took head off after breakdown

[Zrako]

@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...

[Calum]

@Zrako Head Gaskets are not reusable.

My advice, don't take the head off, but I'm guessing it's too late for that now.

Athena head gasket is only a tenner.

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.

[NINJA]

@Zrako Sounds like a 4 stroke with the airbox lid off. LOL

Great job tho!!!

[Zrako]

Well , brand new iridium br9eix after like 30 minutes idling. First 5 minutes was bleeding oil pump. Doesnt smoke too much .

[Calum]

@Zrako A bit rich, but you won't really tell unless you do a plug chop.

[Zrako]

@Calum what exactly does that plug chop is ? Never heard that before

Google my friend.

@Calum whoa . I need to get some standard plugs then . Thanks for help again

[declan]

@Zrako my bikes clog up on idle give it a nice few revs to clear it out

[Mightyman]

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.

[Calum]

@Mightyman and you know what they say about assumptions.

Oh my bad, seriously I thought it was common knowledge.

[Zrako]

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?

[andrewj1680]

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

[Zrako]

Cant find the spring for sale . Just the new shaft

[andrewj1680]

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

Worse case its only £41+vat complete new
