It runs.

And goes into all 5 gears, spins the tyre at will, scares the poop out of me! Not that I've ridden it up and down the road today, oh no.

Then it broke down.

Ran like the choke was on and smoked like a Fergusen tractor, and generally was a very unhappy camper. Thought the crank seals had gone, but it turned out that not only had it vibrated loose the horn, the speedo cable, the seat mountings, but also the pilot jet out of the carb!

Once re-fitted it runs strongly, ticks over, and wakes the neighbour on nightshift up. However, it's not what you'd call an "easy starter" ten boot (yes I put my MX boots on to attempt to start it) destroying kicks at least to fire it up, but once it's going it sounds sweet and is piddling oil out of every joint on the exhaust

but man, each of those kicks feels like you're turning over a cement filled lorry, talk about compression!

Also wired up a brake light and have started to work out the wiring for the lights. One thing I must do is sort out a way of killing the engine, as it just sat in the garage spinning its tyre when I tried to stall it! Had to shove my fist into the open carb in the end.

But, it runs!

Goes into gear, steers straight and pulls like a bl__dy train.

Happy little fellow I am.

Then I got on with working on the Triump which is what I was supposed to be doing all day!

However, it really is an absolute pain to start. Can't find a consistent way of starting it - doesn't seem to need choke (or does it?) and kicking it is bl__dy hard work, can't find compression, so I'm just kicking in the dark. Any advice?

Sorry, it's 465 that has been stood for a few (nearly thirty!) years. It seems to run fine, just a b__ch to start. Is there a knack to it like there is with my XT 500?

Glad to here ya got er goin Dave. Hate to think I`d come all the way to Devon just to have to work on the thing before i could ride it  Cheesy Cheesy Cheesy

So is it a little harder to start than that new CCM ?
How ya likein that girly bike anyway ? Cheesy Cheesy

Yes , it`s suppose to have enuff compres to dislocate ur knee and wrench ur back !
Don`t know of any particular starting ritual, if it`s jetted good and the mix is good, fresh plug of course.    Choke on, stab it a time or two, should come to life...like any other Yam 2t.

Of course ya gotta have enuff lead in ur ar_e to spin it fairly hard Grin

500 2 strokes are the same as a large 4 stroke to start, choke on, no throttle, just past TDC & sink the boot in..

if it's jetted correctly & in half decent condition it should take  2-3 kicks..

When you start a 465, you want to kick it so hard that it keeps the motor spinning after your boot has come to rest. Basically put all your momentum into that little freakin kicker. Finding TDC helps greatly in starting the bike.

My 465 is still a b__ch to start. I just catch that sucker in gear as my little workshop is on top of a hill (with a paved driveway going up the hill). Once its hot then it takes a single kick to start it up every single time.

Does this sound like the problems that you are having?

they free up after a few runs... I had all manner of trouble starting my 465 originally...

here's how mine starts now..

you can feel it reach TDC, if you sit back on the seat it makes it easier to kick it over.. the best advice is don't get frustrated and kick away at it make every kick the same..

fresh fuel is always needed and sometimes it might get fussy about plugs...

Good Luck!!!

Cheers!

Sounds like the same thing that was wrong with my little toe poke.

The pilot was too lean and even with the choke on it wouldnt kick off from cold.
You could roll start it down the side of a speed hump and then after that it would go first stab.
Now it starts with the choke. Takes a few kicks usually but then away it goes. Or it stops as soon as it starts because with all the vibrations of it running under its own steam for all of 2 or 3 revolutions the choke lever flips down and it konks out.

Don't start it, just park it in the garage and stare at it!  Grin

Okay, it starts without choke from cold (eventually) won't even try with the choke on so I assume it's running rich. Doesn't get any easier to start when it's hot either, still a right pig!

Cannot seem to find compression either, seems to have loads two or three times per kick. When I do get it right (seldom) it fires right up and kicking it feels different, smoother, but I can't find the sweet spot consistently.

Must be a knack, I just can't seem to get it!

    I find that the XT500 has a well defined start routine, and top dead centre is easy to locate.
   
    The IT465 is a bit different, as you can feel bottom dead centre as well, maybe it's the primary compression in the crankcase ?
    I am too new to the big bores to offer experienced starting advice and maybe I have just got lucky so far !!

Dave you are right - you can feel the bottom end compression when turning over the motor. you will feel resistance against the kickstarter from bottom end compression but the top end compression will be far greater, this is the one you need to push the kickstarter through slowly, then return the kickstarter to the top & kick the engine over
