I have been having trouble with oil smoke on the right side of my 76 gl 1000,I took it to the local honda mechanic and he feels that the oil ring is stuck on the back cylinder,the valves ,guides and valve seals were done 2 months ago so that shouldn,t be the problem.the mechanic gave me a can of a product called omc engine tuner that he has used with alot of success to cure stuck rings.it made the problem worse,so i changed the oil and filter and added some cd2 additive,this seems to have heped the smoke but now the bike has no power below 3000 revs,above 3000 works great,any ideas or suggestions?thanks in advance

Is there any chance that the additive might be causing this and might need to be run through the tank before it will run better?

I have had great success with a producted called "Marvel Mystery Oil"

A buddy of mine bought a boat with a seazed engine from lack of use. Told him to remove the plugs and fill the cylinders with MMO. Next day it cranked right over.

Father in law gave me a Sears tractor that had run dry of oil, added MMo and got her turned over again/drained re-filled with fresh oil and have used the same tractor for 2 years.

My75 winghad sat for 9 years with only 400 miles run on her. Didnt even run when I got her. Finally got the carbs cleaned and re-built. Fired her up she smoked something terribly. drained and re-filled oil with one quart of MMO and the rest fresh oil, put 200 miles on her and she smokes no more........................



My 2 cents!:jumper:

PS: If it wasnt doing this before the head job I would check to see if the 2 o-rings are installed correctly on the oil bleed/feed tube that goes from the block to the head. If theres only one, it may be leaking thru..................

It's likely any additive would make the engine smoke more while it's in use. It might be a good idea to do a compression check, if you have a solidly stuck oil ring it could score the cylinder, or there's the possibility of a broken compression ring, a comp test should go far to eliminate those possibilities.

the cylinder in question has 145 pounds of compression,i am going to try driving it for a day or 2 see if this additive will clear things up,if not i guess i,ll be tearing it apart

Andrewns5, as a rule oil rings aren't that prone to sticking (or at least staying stuck), most modern motor oil's contain many additives to prevent sticking rings.

Just because the valve guides & seals were worked on doesn't mean there isn't still a problem there. It's easy to cut a valve seal while installing or make some other assembly mistake.

As far as the power drop off below 3000, make sure one of your spark plugs isn't fouled or that your air filter isn't plugged & oil soaked.

You might just try riding the bike hard for a 1000 miles of so to see if the oil problemdecreases a little (ride it hard enough to heat the pistons good & hot). Also, make sure the engine oil level isn't over filled.

the problem existed before the valves were done,the bike sat for 6 years before i bought it,it had a burnt valve on the other side so i had both sides done ,that work has been checked and seems to be fine,the problem is more annoying than anything,it used a litre of oil in 700 miles but it is enough to make me want to cure the problem,i installed new plugs last night,the air filter is new,I am going to take it out and ride it for a few days see what happens,i don,t want to hurt the engine so if it doesn,t clear up i am going to take it off the road and tear it down,i am too far into this now to give up,at this rate this bike will soon be totally rebuilt.i have had the carbs rebuilt,new exhaust,new timing belts,new dana electronic ignition,fork seals,new tires,new 7 volt regulator,its a good thing I really like old gold wings or i would have given up a long time ago

i guess it is time to pull the engine,the mechanic thinks i have a broken oil ring,pulled the head the cylinder looks fine,no scratches etc.after the price the shop gave me to tear it down ,myself and a mechanic friend of mine are going to attempt it.i have a clymer manual,is there anything in that manual that is inaccurate or wrong that i should know about.is there an aftermarket chain tensioner one can install on the primary chain and if so where would a person find it.since we are splitting the engine I am going to start at the crank and redo the whole thing.thanks for any and all replies.

I don't know of aftermarket chain or tensioner but the stripdown is straightforward enough. If I was going that far I would probably put a full set of rings on all the pistons, top end should stay tight for years after that. Good luck with it. :waving:

we are going to strip it as far as the crank check all bearings,replace everything that is at all worn,primary chain,etc,measure everything and bring the whole engine up to new spec,i want this bike to last many years so i am going to do it all right the first time,the heads and valves have already been redone so i may as well do the rest of it properly

It's a great opportunity to make her look and run like new. Degrease and clean up the case and repaint it too. It will be a goodly job andnot aninconsiderable expense but when done you'll have a brand new engine and gearbox for all practical purposes. Long as you're at it don't forget to renew the wiring. Take some pictures as you go and post them, it would be nice to see how it's going.

Good luck with the job Andrew. Take your time and you will have an engine that will last years and years. I would be inclined to replace the water pump while I had it stripped down.
