My Comet is currently drained while I change some of its modifications including fitting an external remote oil filter and if I remember correctly the oil I've bought to put in is 0 or 5- 40 synthetic. Previously I've always used Castrol GTX.
NO LEAKES! Either it is out of oil or it is not a Vincent They all leak oil....Just some more then others.. If yours is still holding dry then congrats.. There are many small passageways in your bike I would think 20/50 or thinner would be fine even in TX heat, (this coming from a former Austin TX resident- Go Long Horns) That's why I like the 15/40 weight...The oil pump really is not a high pressure affair and anything we can do to keep the cooling and lubricating oil moving should be encouraged.. My thoughts are thick oil would not help here...I do use a thicker GL-4 gear oil in the transmission though not that thick..OK I have to ask what kind of Airplane do you have.... Cheers, EricTexas. It was 102 here today and 105 yesterday. Thin oil leaks out more easily than the heavy stuff, but if you change oil every 2000 miles I doubt it matters much. I use 25/65 by Phillips in my old airplane and I thought about using that,. It's a big 800 HP radial, but it is a little pricey. I think all the current oils are pretty darn good . Do you think that the heavy oils can add a little cushioning along with there slippery side?
No leaks so far=)
Well I did ride the bike and got stranded five miles from home. Had to call a buddy with a truck to come fetch me home. Bike did find for five minutes and then when going up a hill it started to bog down and finally quit at the top. After looking over all the wiring and checking the plugs it started up and ran for 30 seconds. If I let it set for five minutes it would run for about a minute. Had fuel flowing from both carbs . Got it home and called Tom and we both thought it sounded like a spark issue. Couldn't sleep so at 11pm I went out in the garage and looked at the wires again. Thought it would be easier if I took the battery out so I did that, and since I had the battery out I might just as well give her a charge. So I tilted the battery a little to see where the fluid level was and low and behold there was almost no juice in her. You guessed it no spark under a load or at least not for long. Charged her up over night and took her for a 15 mile ride this morning and all was well. Idle was normal. The new springs must have worked. So while I had her hot I decided to change the oil. I think I have everything drained pretty well, and my big brass oil filter nut came right off. I soaked the new filter in oil and tightened everything back up. Now I just need to add the new oil. I was going to use a 50 SAE straight weight. I don't want to overfill it. I think the book mentions 6 pints, but should I start with 5 pints and run it a little first and then just add more if the level is ok? Next adventure will be the clutch!
