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

…I have a DEP modified to match the tuning,they tell me that it sounds like a factory 50cc moped not a tuned 170cc, that's until the power band then it screams like a TZ125. When was bought bone stock and abused sounded more serious I could say.
-
Ive ridden it for 31 miles and it still feels very lumpy with compression when I kick it over. Nothing like when I put a freshly rebored 3mb and piston on it. I could turn it over with my hand then (after riding!).
I might be over worrying but I’m wondering if I could do with a thicker base gasket. The standard one is at least 1mm thick I believe?… -
Hey bud! Haven’t taken it over 5K so PV isn’t an issue. Chain was very slack, it must’ve bedded in during the 30mile shakedown ride a lot more than I thought possible! I’ve adjusted it up so it has just over 25mm play. I’m waiting till tomorrow to ride it cause I’ve had a few beers…
I’m probably worrying too much. I almost expect something to go wrong…
-
Chain adjustment has gotten rid of the shuddering, just done 3 miles after warming up and it is riding sweet. Only niggle is at certain low revs when I’m just maintaining speed it sounds almost like there are a few tiny ball bearings in the expansion chamber. I’m guessing it’s a bit of a mixture adjustment in the pilot jet/valve cutaway range. Going to try and richen the airscrew and see what happens…
Tick over is very stable so I don’t think it’s a small air leak…All in all it’s good. Pulls like a fuxin freight train @ low revs. Totally different animal!

They were painted bud. The bike was first registered black with red frame and stickers. Most of the panels were dark/navy blue. So it had a hard life before I got it, 16 registered keepers! (I’d love to know how many times it was stolen!)…
It’s an old mongrel, not a righteous, numbers matching survivor. Though I am trying to turn it into an honest, righteous bike…

I think our DT fates are close,mine was at a coastal rental shop and I leave on a semi touristic island.Was in Germany for 2 years before coming to Greece 11 years as rental.
A properly raped stock unserviced bike when bought,56K km's on factory piston,fux even oil's/fluids where stock.
