Need advice before I start..

Postby higgybear » Wed Nov 21, 2012 8:42 am



Hello,

I’m new to these forums also a new wing owner, however grew up around wings. My Father has owned a wing since their release. Here is my issue. I have picked up a 1987 Interstate for almost nothing, It has been sitting for at least 6 years and at one point someone began to tear down the engine. But stopped shortly after removing the timing belts. The bike is complete but does need allot of TLC. It shows 18,365 on the OD. My concerns are what should I look out for before attempting to get it to turn over. Any advise would be great…

First......Obviously put on a new set of belts,pull the plugs and turn the crankshaft by HAND ONLY 3 full turns.It should turn with no binding.Stop and check if it does.Don't force it.
Verify the timing marks are on the money.Ya gotta get right down eye level with them.
One tooth off and it will still run but 3 teeth off and it can tick a valve.

Second....If it checks OK....then electric crank it with fresh oil (no plugs) to build oil pressure.

Third.....After that,if possible,check the compression....at least 125 psi with no more than 5 psi difference between any cylinders.
This is a good time to check for spark.

The last is the gas....Expect the worse and hope for the best.
6 years is a long time to set up.The carbs may need tending to.
Don't forget...if a float sticks,it can fill one cylinder with gas and hydrolock the engine.
Not detrimental but very annoying.Pull the plugs,crank the engine to clear the cylinder....It will shoot gas 10 feet so be careful.
If it hydrolocks,the engine may crank a half turn the stop abruptly.Sounding like a bad starter (been there too :mrgreen: ).
Keep us posted on your progress or any questions.

While the timing belts are off change all fluids.
If the bike sat for six years with gas in it. Take the carbs off and clean them. Save yourself some guff down the road.
Looking at new tires too. Don't forget to check those wheel bearings also.
Plus hard wire the stator plug by the battery.
Some use Honda antifreez, myself I use Peek. Just make sure it doesn't contain silicia.
Any questions along the way just ask. A good group here with lots of good info... :ugeek:
Enjoy the ride. They are all good, just some better than others.

Well, First off I thank you greatly for the advice. It did help me allot this weekend when I finally got to work on this bike. Well to make a long story short, I Think this motor is shot and the person before must have known that. Cylinder #3 was full of nasty water. After purging it I pulled the head off to inspect the damage, and found apiece of the piston had broke off and rattled around for a bit. So I was unable to check to see how deep the damage was to the cylinder wall. But I assume if its feels like deep gouges to the touch. Then it’s pretty deep.

Now I’m looking into options, get the engine rebuild? I have no idea what that will cost. Or I did find an 87 gold wing on craigslist being parted out for only $300 for frame and driveline. Seller states it has 87K on the motor and that he can fire up the engine if I want to verify it runs properly. No my concerns are, is 87k high mileage for a bike? Or would I be better off having the motor rebuilt. Any advice would be great.

Buy the running engine.
Taken care of,they can run 200k plus.
You can't buy a gasket kit for that money let alone new parts.

87K is OK if it was taken care of. I think it's cheaper to buy a used motor than rebuild one. I think a gasket kit is $150 or more. Plus parts and machine work. If you have the time you could do a tear down and just replace what is needed. Lot of options here. If he will let you hear the motor run, see if he will do a compression check?

Yup. For the cost of rebuilding an engine, you could buy several (10-15) used engines from bike breakers and eBay.
