Bringing an Across Back to Life - help please

Hey Jess

Was it left outside or undercover ? I have bought plenty of bikes that have sat for years and the oil hasnt been too bad, its generally the ones that sat outside where moisture has effected the oil that can be tricky. My advice is dump the oil, if it comes out brown \ black but is smooth then let it all drain out and replace with fresh oil. If comes out sludgy then get as much as you ca then refill with a synthntic oil for start up , run for abit, then look at replacing it again with fresh stuff. If you are worried about it being seized, pull the spark plugs out and pour a teaspoon oil down each barrel , leave for a few days then attempt to start it.

You can dump the fuel in the tank by removing the fuel line from the petcock and set the petcock to reserve, if the fuel comes out rusty then your tank might be affected.

Once you have it running, might pay to run a can of Three Bond Engine conditioner through it which will remove all the excess carbon build up

1. Warm engine to normal operating temperature. Shake can well.

1. Stop engine, remove a convenient vacuum hose from intake manifold/throttle body.

1. Spray for approx. 15 seconds.

1. Allow to stand for 5 minutes before proceeding to next step.

1. Start engine and accelerate enough so that the engine doesn't stall. Empty remainder of can into intake manifold/throttle body.

1. When can is nearly empty stop engine and allow remainder of conditioner to sit for a further 5 minutes.

1. Re-attach vacuum hose.

1. Start vehicle and run for minimum 2 minutes before road testing vehicle.

 

make sure you bleed the brakes, a few years outside and the brake fluid will be mush

 

All of the above is great advice, kiffsta is a master resusitating old bikes.

Feel free to turn this into a build thread with pictures

 

My bandit was outside for a period of time, when I drained the oil it was lumpy. If you're going to crank it I'd say invest in some oil (I find yamalube quite good) before you do it so you don't push it through the engine. I personally wouldn't worry about it being in the engine though, it's probably mostly drained into the sump.

When I took my head off there was only the new oil in the engine so yeh. Drain the carbies and ensure you use fresh fuel though, nothing like stale fuel to bugger your rings.

 

Hi Jessica
By the sound of things, you've got your work cut out. Any bike that has sat out for that length of time is going to generate issues. The mortal enemy is moisture, it is destructive and caused so many problems.
I would drain the fuel and oil to start with. Put fresh fuel and oil and hook up a battery and she if the bike will start.
If you can get it running you are on your way. Look forward to hearing how you get on. Good luck!

 

I'm here in holsworthy,if you need a hand let me know.

They look so much better Murdo

 

I checked my spares box and I dont have any, all I have is a full set of carbs which I do t want to break apart, try your local dealer they should be able to supply the diaphragm only

 

That was a decent tear, need that replaced. Dealers vary from place to place, get on the blower and try a few.
