I love Marvel Mystery Oil and I remember that Grampa told me that if you use MMO in your oil you need to reduce the time between oil changes as it causes the oil to get dirtier quicker and also is thinner than the manufacturers recommended oil. I still use it when I get a "New to Me" bike as I do not know what the previous owner did or how well he maintained the bike.
I swear by the stuff, I have used it for all kinds of things. Your Grampa was right about changing oil more frequently, because it does break up sludge and build up that will end up in your oil and filter. Thanks for watching 🐲
Right on! Appreciate you watching 🐲! Check back now and then, I plan on making videos of this bike for the next 20 years. I plan to tear it apart this coming winter and do alot of work including a full elaborate custom paint job. I'm going to document some trips as well, and of course and problems or repairs needed along the journey.
Finally! Proof that MMO works! I'm a very recent convert. I too lumped it with snake oil, just lightens your wallet. I got a 92 Honda 750 Nighthawk less than 2 yrs ago. 20k miles 4th owner. Ran, OK, rode it a month with carb cleaner in the gas. That winter did it all to it. Carb seperate, clean and rejet. Ran good last season put on 4k miles. Did compression tests 135-145 psi. This season caught some posts about MMO. Have run it now 4 tanks with 2oz. in the just under 5 gal. tank. Power keeps going up! I'll run this stuff forever! Old bikes with low miles, unknown maint. Rings have to be partially seized in the grooves. I'll get new comp. test #s if we get a week of rain scheduled, otherwise I'm riding!
UPDATE: Just tested my 92 Honda 750 Nighthawk. After 1k miles of 2 oz. of MMO in every tank of gas. Cold comp. test 150 150 155 155 That's an increase of 10-15 PSI per cylinder. I'll run it all summer with the MMO and see what I have come winter. For the record I won't put it in the oil.
I wasn't a believer until I actually started using it about 20 years ago. People used to tell me about it, but I thought it was just snake oil. Then I started using and haven't looked back. I use it far many different things, it has so many uses. Glad to hear the bike has improved!
Cylinder pressure is a function of compression ratio x atmospheric pressure, usually 14 .3psi at sea level. for e.g, 10: 1 compression ratio would equal 143psi so to expect 180psi is unrealistic on this engine, it would mean a compression ratio of 12.5 :1 that's racing engine world high octane fuel etc. Nice bike though.
You have not calculated cam/valve timing events which actually have more control over dynamic compression. I have a 2000hp turbo charged engine that pumps 105-115 across all 8 on 12-1 mechanical calculated compression
This equation everyone always refers to must be inaccurate, I just got 160psi on this one and I have seen 170psi-175 on these engines. Anyway it runs great, so I'm happy!
Another question about compression tests VS compression ratio. Your Wing has 9.0 to 1. At 14.7 to one (sea level air press.) it should get 132 psi. Why/how is a new engine to get 175psi??? I have yet to test an engine and get near the middle, let alone upper compression #s. Had a problem with my tester, needed new Schrader valve at the end where it screws into the plug hole. Got to really watch your tester and not trust it, maybe try a few.
Apparently the equation just doesn't work out. I have tested many 1000, 1100, 1200's goldwings that had 160+ and sometimes it's old and ragged and your expecting low numbers and it comes out way high. I have had some bikes through the years test 200psi+ Not sure why the equation doesn't work always, but it doesn't. Thanks for watching 🐲
Both, the bike had sat for awile, so the rings were possibly sticking, so the fuel burning and the oil lubricating loosened them up, also the marvel cleans the deposits off the valves and seats to allow them the seal better resulting in more compression and power. Thanks for watching 🐲
Not sure on that, most of the miles I put on were back roads and twisty mountain roads. I wasn't going for mpg as much as I was going for more compression because I was concerned about the internal health of the engine, turns out it was fine.

That’s an excellent moto. 🏍️

Oh, I'm a firm believer in the stuff, I have been using it forever on just about anything with an engine. Legit stuff for sure. Thanks for watching 🐲
Fill each cylinder at the top of compression with Marvalist and let it sit a few days.
Make sure you have some valve gap.
Been a while. Nice work.
Thanks, been out riding🐲

140-150 is great. I have a low milage GL1000 and I get around 142-147 cold. Depends on how fast you can spin the motor.
Yeah, I'm happy with the 140psi-150psi. It may even come up some more as I ride and use the Marvel.
How much Marvel do you add to the gas ?
@kevinterifay9904 supposed to be 4oz per 10 gallons normally. I put a little more than that to make quicker work of it.

just be sure that you open throttle all the way when you crank for compression
Yes throttle wide open

How much MMO did you add to the crankcase ?
About 3/4 of a quart
so, is it the MM oil in the gas or oil that raised your compression?

how many miles to the gallon are ya getting on the hwy?
Not sure on that, most of the miles I put on were back roads and twisty mountain roads. I wasn't going for mpg as much as I was going for more compression because I was concerned about the internal health of the engine, turns out it was fine.
