At 5000 rpm, the spark plug for each cylinder fires 2500 times. In a four stroke engine, two strokes occur for every revolution of the crankshaft. The intake stroke occurs as the piston travels down (1/2 crank revolution, or 180 degrees). Then the compression stroke equals the second 180 degree crank revolution. Same for power stroke and exhaust stroke. In a 2 stroke engine, the plug fires once for every revolution of the crankshaft.
Bro like the fact that you have these awesome knowledgeable individuals...and they put out great info! Keep it up man...hope your health goes on the up and up!
Awesome we can get 98 here. So 98 dead Dino's sounds good to me. Thanks again Blockhead we are always getting awesome info off your channel in a very entertaining way good job again mate.
Cool info. Luckily we can readily get ethanol free fuel here in 🇦🇺. Ethanol will boost your octane rating but reduce the power/L or gal. You can then go into the whole explanation of the difference in octane rating measures in US v/s Europe & 🇦🇺. (RON+MON)/2 vs RON effectively, as I vaguely remember from a high school physics class
Awesome info from Mike and slickwideglide , love it when you go there Blockhead and you get the straight-up no bullshit info from very knowledgeable HD blokes
from what I have read the high octane premium gas still has 10% ethanol which is used to boost the octane so wouldnt it be better to buy the ethanol free gas that in my area is 87 octane and add an additive?
AvGas is 100 octane. You can get it at airports. For clarity sake, are we suggesting we should be running 100 octane in a completely stock bike, or say stage 1 bike? Or is this more applicable to a built-out 131 torque monster?
Follow the recommendation unless the motor has been built. Buy the best gas you can afford, as in avoid the no name stations with rusty pumps and such. You only really have to start veering from the recommended numbers when you've introduced changes to the system. Higher octane isn't going to hurt anything, it just might not offer any kind advantages. Good quality fuel is going to make a bigger difference when all else is equal.
Here in Tampa my choice is 93, sometimes 91 octane, in E10. The only ethanol free gas I can get is 89 octane from Wawa. Which one should I run in a Milwaukee-8 107?
I’m actually looking at a old gas station that has a stainless steel tank buried for E85. The closest store we have that sells it now is over an hour away... I want the gas station, but not the store!
Has anyone used a fuel injection cleaner for their bike?? I got my bike a few months ago and is my only means of transportation. So I want to make sure I am taking good care of the engine and all its parts. Just looking for some advice/recommendations from people who know more than me and have been riding longer. Thanks ya'll!
So then we don't need to run a hot octane since Harley motors at peak from the factory are attend to one? He said higher the compression the higher the octane.
Just want to give a shout out to "Boston Mike " he wasn't my instructor, we actually went through MMI together way back when! Please pass on that "Bulldog" says says what's up.... does he still have that Badboy?
Its funny how you guys in the States have trouble finding ethanol free gas,and when you do,it is low octane. Were up here in Canada all big named gas stations have Ethanol free gas,that is high octane. I go to Chevron and get 94 Octane Ethanol free gas all the time for both my bikes
How much are you paying for a gallon of ethanol free? Also, climate up there is considerably harsher than Florida. I suspect ethanol free is easier on engines in colder weather and hits flash point sooner. I used to live in Montana as a kid. But when you're 10 you don't care about fuel efficiency.
@@tommyarnold890 If you haven’t seen it take a look at fortnine’s post on fuel stabiliser modern fuel is a cocktail of additives & most probably has been for many years. Ethanol has been added to petrol to increase the octane level along with the “green BS” the problem with it is that it attracts water and you get worse mileage out of it . I am beginning to think that tuning the engine to get much more HP out of a motor is becoming very expensive and more trouble than it is worth if you have to rely on additives to keep it running .
Our federal government heavily subsidizes the crops used to produce ethanol and biodiesel, so they get produced at artificially lower costs. Adding them to our fuel helps keep the cost of fuel artificially lower.
@@timconway7860 meanwhile the ethanol erodes the seals and parts in the engine resulting in the engine tearing itself apart. It was a stop gap measure that became the status quo by political hacks that didn't understand what they were doing.

Why would you want to slow down the explosion in the engine? The faster the explosion the more energy released which increases the pressure faster in the engine. Therefore more hp. What's your thoughts on this?
That is strange that you guys seem to have hard times to find high octane ethanol-free gas ... I always assumed youd' have better fuel than the rest of the world. Here in France the 98 octane ethanol-free is a standard. You can find 95-E10 that is 95 octane with 10% max ethanol. Though your mileage can vary quite a bit from one brand to another.
Nice to know. Basically. If you want to make an explosion for an action movie, and you wish to have it grand. Then you would want to go with low octane fuel? But if you have a piston driven airoplane like a Mustang or Spitfire, then you want to go for +100 octane.
What's this "and it's more efficient" part?? You either have knock or ya don't. If you don't have it, there's not an uncontrolled burn, and there's no more efficiency coming out of the fuel. BMEP isn't higher, BSFC isn't lower.... It's straight placebo if you think you get better mileage or mOaR pOwAh hahahaha
I never assumed mechanics were anything but smart. But these dudes are straight up motorcycle savants.
At 5000 rpm, the spark plug for each cylinder fires 2500 times. In a four stroke engine, two strokes occur for every revolution of the crankshaft. The intake stroke occurs as the piston travels down (1/2 crank revolution, or 180 degrees). Then the compression stroke equals the second 180 degree crank revolution. Same for power stroke and exhaust stroke. In a 2 stroke engine, the plug fires once for every revolution of the crankshaft.
i. noticed that too was about to comment but you already did it.
Right?
Bro like the fact that you have these awesome knowledgeable individuals...and they put out great info! Keep it up man...hope your health goes on the up and up!
He made that easy to understand...I know when I go out of state and can get 93 dead dinos I get better mileage.
I could listen to these guys all day. Thx Block
Awesome we can get 98 here. So 98 dead Dino's sounds good to me. Thanks again Blockhead we are always getting awesome info off your channel in a very entertaining way good job again mate.
Just to clarify when he explained 14:1 fuel air ratio is not the same as compression ratio @5:30
Any recommendation on octane booster for travel in areas where you can’t even get 91/93 gas?

As an apprentice mechanic I found that really interesting. Cheers fellas.
Do you need a tune when you use octane boosters?
So I have a 150cc bike. I've just been using regular unleaded. Should I use a higher octane gas?
from what I have read the high octane premium gas still has 10% ethanol which is used to boost the octane so wouldnt it be better to buy the ethanol free gas that in my area is 87 octane and add an additive?

Man, THESE are the kinds of dudes you want working on your bike!
need more Boston mike explain-in things...Mikes techy moments...
this is the torque test channel intro almost to a tee
I wanna know if you can raise 91 octane pump gas to 100 with octane booster.
When are we seeing a classic V8 again Block?
is there different methods to calculate octane. is it the same in Europe. just curious.
Learning every day
I bet you that man is a magnificent mechanic
Eeeey anotha ep,and is with Mike,nice XD
Science!
I had learned that in the Army. More you know, right.
I can tell you what my book recommendation is for my 2006 Honda vtx 1300 on the gas, but what would you recommend?

Bro woke me up to how this shit works thanks I’m gonna learn more of that now
Here in Tampa my choice is 93, sometimes 91 octane, in E10. The only ethanol free gas I can get is 89 octane from Wawa. Which one should I run in a Milwaukee-8 107?
Well... I just saw an docu about P75 Mustangs. They used 104 octane.
I’m actually looking at a old gas station that has a stainless steel tank buried for E85. The closest store we have that sells it now is over an hour away... I want the gas station, but not the store!
Where would you even get higher octane fuel?
Educational. Thanks for putting this up 🤘🇳🇿
Good stuff good stuff. damn marketing! Thank you for explaining that octane boost doesn't actually have more octane 👍

Is ethanol free different than non-ethanol
Dead Dino math explained nice!
Makin power ! . 110 vp. Great for the winter storage of the ol girl.
Here in Cyprus we have 95, 98 and 100 octane!!
Different rating system.
@@kc510 100 octane gasoline on motorcycle it’s perfect!!!
Same here in Romania,the 95 is the standard,that's what I always use,95
Awesome I learned a lot. Thanks Blockhead, but now my brain hurts
So then we don't need to run a hot octane since Harley motors at peak from the factory are attend to one? He said higher the compression the higher the octane.
Nice absolutely love my whole life I was raised on harley bikes best evaaa
