I had similar symtoms and photos to yours after alot (dont start guys)
I changed bottom end and no more burning oil now just chucks it out aux shaft seal all over engine
So check bottom end mine looked good but some was amiss
Once a year the wife and i get a night away from kids
Disabled son goes to clumber park with school for night and in law has eldest
Last yr we went to leeds shopping afternoon and out at night want suggestions for this yr
22nd of june not to far away as only for night
Want to enjoy as only time we get to go out together
Thanks
Sorted air leak using the dan st gasket plus injection gasket as both head and manifold are egg shaped just got to replace aux shaft seal as sprayed oil out and lubricated all engine bay and bike carbs need setting as fine when foot down but splutters at cruising/ low revs
Goes like clappers when foot down and no smoke so getting there
Well done helen just shows how strong u are
And with a family as supportive and close as yours you were always going to be okay
As our lass says
You go girl
Think its fuel why not firing on no 3 untill foot down so need to sort carb which prob best balancing
But if i press around manifold onto head the sound changes
Took it for a spin and goes very well and no smoke so was piston ring
But when just crusing it pops and drives like misfire but also a chirping noise started to come from inlet manifold so although tight getting air from injection ports also using fuel and smells of it few oil leaks so that normal
So mite just make it just got to keep foot down
Is was number 3 keith but that issue was oil clogging plug no that issue this time just been thinking about that and wondering if burnt oil left on valve not letting it shut fully hmmm
Dont believe dizzy etc at fault due to fact that sparks perfect and strong upto plug
Plus the carb on number 3 used to pop and spit faint flame out not getting that seems to be low fuel getting into cylinder as although plug damp it not wet
I will try dan wen i get home dinner time just got to charge battery or jump leads
Need a new battery going to try the hand over the seperate carb intakes as well try that
I thought timming as well but orther cylinders running and wen plug out tested on manifold no3 sparking very well
