Well it's not a tractor, But...Honda Magna experts?

We all like our machines! I always said I wouldn't have a road bike until I could have a Harley, well...since the price of a Harley is out of my reach, and my time is growing shorter, I built up an 83' Honda 750 Magna similar to favorite son's 82' Magna out of parts and pieces from everywhere. Nice strong bike!
I want to get it fully serviced up, I always use Lucas lubes in everything but my question is...I understand the clutch in these runs in the engine oil (wet clutch). Am I asking for a major fail if I use Lucas oil stabilizer in the crankcase oil?
The engine has approx 20,000 miles on it so the engine would benefit from the Lucas, but I'm not so sure it's is a good idea for the clutch. Opinions? Thanks.
 
I don't know that model but in H-D wet clutch set-ups additives can cause slipping. Atf is fine in a Sportster trans . Additive EPC [extreme pressure concentrate] will cause slipping as will other "slippery" additives. I would stick to what is wanted in the manual. In a Harley oil is a dry sump system so only the trans compartment is affected . Any additive can be used in the oil tank. In your case I would just use engine oil.
 
There are some great Honda Magna groups with on-line websites. I would ask your question on on of those websites, and also check the Lucus website. Your bike was made before the SJ oils were introduced (with new properties that break down wet clutches), so your owner's manual may still recommend an automotive motor oil. There should be some Honda service bulletins that address motor oils and oil additives.

Motorcycle clutches are fairly easy to rebuild if the clutch linings break down, but removing all the small cluch particles from inside an engine could be expensive and time consuming. I would not risk it. On my older bike I use a motorcycle rated motor oil and change the oil when it is needed. I don't bother with any extra additives.

Will Lucas replace your clutch if you use their recommended additive and the clutch fails?
 
Be careful using any oil with friction modifiers in a wet clutch. Any Japanese bike dealer will have the correct oil for wet clutches. In fact, Lucas oil (see their web site) has an oil especially formulated for wet clutch use. I have used this in a Honda 4 wheeler with good results.
They also have oil for Harleys that has a friction modifier package as does Amsoil and Mobil 1. Doesnt hurt Harley clutch because it is in a separate compartment from engine oil and has its own special type of fluid (similar to ATF)
 
I only use the oil for wet clutches. You can get it in a lot of different brands. Personally I use Mobil 4t. It's made for a wet clutch but kind of expensive. Close to 11 bucks a quart.
 
The V45's are good engines once the oil pump was changed on recall. Use motorcycle specific oil for wet clutches. I think Lucas even makes m/c oil.
 
I, too, run a wet-clutch Honda... There are only certain synthetics that I can use before the clutch starts slipping. The cheapest thing I have found that works in mine is Rotella-T... Another one is Mobil-1 (full synthetic), but it is more expensive. And, don't forget, Honda has an approved synthetic called HP-4... Have fun, be careful...
 
If the quart of oil says energy conserving in the little symbol, then it has friction modifiers, and I wouldn't use it in a bike. I always used Castrol 20-50 for regular oil, or Mobil 1 synthetic 15-50. I run Mobil in my ST1100 and change the oil about every 8-10,000 miles.
 
I use Lucas Motorcycle Oil in my bikes now but I used to be cheap and use Rotella. The Lucas is good stuff.
