1984 gl1200I

Please I need help. I have a 1984 GL1200I with 80000 mi. I have been slowly going through the bike starting with the carbs. Rebuilt carbs and synced. Rebuilt front forks, clutch master and slave, front brake master and changed timing belts. After timing belt change bike ran fine but after a couple of weeks bike began to smoke a birt after warmup. Previously I had added some fuel conditioner and the tank was almost empty. I though I may have added too much and consequently drained tank and filled with new gas. Excessive smoking went away. However a slight tick was noticable after startup. It seemed to to not have a direct relationship with RPM, stayed steady.The bike has been on a stand for about three weeks now and after assembling the front end and all electrical connections I started it up today and noticed a definite valve noise especially on the 2 &4 side. When first started it's not to bad but gets worse the longer it runs. Valve job, lifters what? Could anyone offer some help.

Could be a dirty tappet. Try running some seafoam in the oil for a little bit. They get dirty and sometimes stick causing a ticking noise.

I would vote for the Seafoam too. It has done wonders for a lot of problems in engines.

Thanks for the advice. I am afraid to let it run for very long, trying not to dammage a piston etc. I am going to try and get an oil pressure gauge and measure to make sure oil pump is working. The bike did not heat up very fast so I assume it is working. Stopped up oil port? Sorry I haven't been back, I was on Vacation for a couple of days. Any more suggestions would be greatly appreciated. There is hardly anyone around that will tear into an old Wing and motors aren't my thing.

Check for water in the oil. I had a friend bring me his 84 with no or little oil preasure. I checked the oil and found water in it. On further investigation I found that the oil was a blob in the bottom of the engine, I removed the oil plug and just a few blobs of crap blopped out. On even further investigation I found that at some point in the bikes life the waterpump started leaking and someone had put stopleek in it, and a lot of it(coolent water) Well it stopped the leak alright and spit the water into the oil. Well they must have put in a case of this stuff because the stopleak had globbed the oil in the bottom of the oilpan and stopped up the oil pump. It was like very dirty really thick grease in the bottom of the oilpan. I had to remove the front of the motor, remove the oilpump and pickup tube and strainer and clean it all out. Fill the motor with cleaner, let set for a few days, then drain that out and refill it again, let set for a few days repeate, repeat repeat..... I kept repeating this until I had it all cleaned out. I used the cleaner from my parts cleaner. Replaced the waterpump, put it all back together, used honda anti-freeze in it and the bike has ran fine for the last 3 years. Just something to check. You never know what others will do to one. Never understand why someone would put stopleak in it if the waterpump leep hole is leaking water or oil out of it. It is a indicator that a seal has failed and time for a new pump or rebuild the old one. It could be just a valve too loose, they are not that hard to check and adjust. Someone suggested the fuel pump, you could also hear mine, nothing to worry about. These motors are very tough, I think he rode it back home which is about 5 or 6 miles after it dropped oil preasure. Not a smart thing to do but he said it was raining very hard and did not want to set beside the road. This thing is still running very good and not using any oil.

Sorry I miss read the post. I also vote on the seafoam. Great stuff. Also perform a valve adjustment. Not that hard on that motor. I would suggest if you perform valve adjustment have new valve cover gaskets in hand. When I performed a valve adjustment on mine they were dry rotted and cracked, I tried to reuse them and they leaked.
