Hi I'm a newbie Goldwing owner having just bought a 1985 1200 Aspencade. The engine had been removed then refitted by the previous owner after alternator problems and that was as far as he had got. I bought the incomplete bike and assembled it. My dilemma is that when I started the engine it sounds like a diesel, there is a knocking sound coming from the engine.....mainly from the head ends. I removed the radiator and checked the timing as he had the belts off but everything is fine. As I said if it was a diesel I would not be worried....but..... The previous owner is adamant that it was not like that before he removed the engine and I tend to believe him. 

So anyone have any ideas??

My first reaction would have been the timing belts, but you say they are good, Liam and Foster are going to be the most help here If they don't respond tonight I'll send them a mail in the morning for you.

I am not a complete idiot -- some bits are missing not many

When you say you have checked the timing of the belts, have you checked them against the crank timing mark inside the round plug at the top rear of the engine?

How long was the bike idle during the dismantled phase?

4 Cylinder wings run like pigs if the carburettors are not set up well.

I must admit I thought of carbs as soon as I read the post my 1100 still rattles and pops until it is well and truly warmed up then its fine, 35 year old carbs are very hard to set up correctly.

Thanks for the quick replys, the bike starts idles and revs ok, the only thing might be that it is running rich as it does not need the choke,  but in saying that it's not throwing out black smoke. When I checked the timing I had the inspection plug out and the 'T' showing with no1 piston at TDC and both cam pulleys pointing as they should. The only thing was there was no arrow on the crank pulley pointing upwards....but I assumed that as everything else was lining up it would not matter as its only a pulley. The first thing I did after it started was to sync the carbs as I thought that was why the engine was knocking. The previous guy replaced the carbs and manifold. Although they were quite a bit out it did not make any difference to the clattering noise. To answer another of the questions the bike was sitting for a couple of years.

Just a quick update, I checked out the plug leads today and they were correct.....I was pretty confident that they were as the bike starts and revs ok. I have read up on noisy tapets due to them needing bleeding, I don't know what that sounds like on a Wing though, could that be the problem?

I removed the tappets today to make sure that they were bled.....they were so I've came to the conclusion that the engine noise is mechanical. I took it up the road for about 1 mile, although it drove ok the engine was not sounding good. So I've decided to sell the bike as is, although I'd get more for the bike if I was to break the bike for parts.

Thanks to all who took the time to reply.

Dave.
