Pissing coolant from the bottom of the barrel, where the casings meet. They’re not a matched pair and one is a hair higher at the front on the clutch side. Perfect at the back…
Going to lap the front with wet and dry and a 10cm (10cm X 10cm) square of plate glass…
It was the one time I never used sealant on the base gasket, plus I used my Vertex gasket on the Tzr! I ended up using one of those 0.5mm fleabay ones. A decent thickness gasket and copper spray sealant and I’d probably never had a problem… -

Ha! I was just going to ask you if it was the piston or the LE bearing!…
File each side of the piston,the bearing must drop and have a little play.
I believe 0,5mm or 0,75mm of each side will do,measure your bearing because they are not all the same.

Why thank you Sir!…I did get round to doing some things today, once I stopped feeling sorry for myself:
Lapped it smooth and ‘all over’ even as I could with what I have to hand…
I always hate putting on a top end with the engine in-frame, but what can you do?
March or die! Can’t give up either way…I had to remove the side cover and rotor so I could remove the stator, all so I could replace and tighten the coolant pipe-mount/engine-bolt! I did manage to torque up the stator nut this time because I could lock the crank via the little/small end…
-
Yeah, I did wonder…
I’m going to leave it overnight for the leak-down test, before I start throwing it back together again. It’s dry so far…
Hopefully tomorrow will be the day! This 2 weeks has been the longest I’ve been without a ride since I got it on the road, I think!…
I don’t get any emoji ~smiley faces anymore, is this just me on iPhone you recon?…

I forgot to ask: Does the Athena kit give the kickstart a more ‘compression’ feel than the standard? I used to be able to turn it over by hand on the kickstart…
Yes it does. The first time I tried to start the engine it kicked back like a 4T and did little damage to my ankle. I had tha face "what the fux it's my XT600 all over again".
After the run in km's never happened.Your spark plug wire must go from the other side,if you follow Yamaha schematics.

The high tension lead? Interesting. I guess all my loom and wiring is bass ackwards!
…I had a 400 single that you had to find the sweet spot on, or it’d try and break your ankle! It had a decompression valve/lever that I could never get on with. You got to love 4/ singles. It’s like riding a 2 wheel tractor

No leaks as of yet: 10.30pm

I have the newer oil pump setup so can adjust it more be good to see if anyone has a guide on how much it needs adjusting by
I’m going to be running the standard pump to match the standard 28mm carb…
——————-
I think you need to work out the cm2 of the 28mm carb. Then the cm2 of 32mm. Figure out the % increase of the two. Then increase oil at WOT by the same %…
Or does that sound like BS?…

Went for a test ride, it was OK but getting misfires/knocking at certain lower revs. That and it was taking a bit of effort to tick over cold…
First thought was check the plug. It looks sweet. Looked to the right at the carb thinking it might be an air leak and remembered I’d changed the rubber inlet manifold. I forgot to blank off the 2T oil pipe inlet! What a twat?!….
🫤Gonna test it tomorrow with the oil pipe blanked off!…
-
Only been to the shop and back so I never properly warmed up. It felt really juddery at low revs, which I put down to the chain being as slack as a wizards sleeve (since corrected!). I’ve yet to take it for a proper test cause I’m all flued up and feel like shit!…
One thing I’ve meant to ask is about the exhaust tone/note. Not at the tailpipe but deep in the expansion chamber. It sounds really different from before. Anyone gone from standard 3mb to Athena and noticed a similar thing, or not? Any info appreciated
