Octane Booster

73 shovel

cowboy, my last bike was also a 73. knew of a few others, all ran very well. must have been a good year. really miss that bike. i stripped everything off non- essential. finally got it where i didn't need a battery. the good ol days gabby

And, even if you have a built motor, octane boosters are pretty ineffective. I run VP C08 in built motors for racing or Sunoco 110. It's quite expensive.

But, stock compression should run fine on regular pump gas. Pulling trailers, adding sidecars (load) can cause a little detonation if you're on the edge with compression and you might wanna run higher octane pump gas, but I don't mess with bottle octane boosters.

I find NO MATTER the octane (unless 100+)

*** watching the RPM and shifting DOWN a gear when PULLING

** instead off LUGGING motor will make the BIG DIFFERENCE.....no nock,ping,rattle....

much easier on the life of motor and will run on LESS octane when needed.

Just the way I do it!

sorry to hear

Sorry to hear about the loss of your friend. It will be a thing thing to go through. Ya really do fell like everyone is out to get ya,
If ya look at the owners manual mine reads "at least 91 octane. I can really tell the difference. I run 100% gasoline from shell or Sunoco. store Bike runs GREAT to and from work and putting around. The Meijer across the street from my work have pumps that state they are 100% gasoline.
When I cannot find that, I always go with the high grade where ever it is
and carry a bottle of lucas with me. Tell ya one thing. For some reason it runs like crap on BP gas..So does my car. I mean a real difference. Could be the pumps I do not know but I have tried it a few times and same results each time. Methanol is what ya stay away from.

moth balls

ya could always put moth balls in the gas. That'll do ya real good.
My buddies still put them in the derby engine cars. Tried it once on a mini bike years ago as well as sneaking some octane booster into the dirtbike and a go cart I had as a kid. Dad could smell the fumes and knew what I did with his racing gas.The Marathon in a town about sixteen miles from has 105 in a pump. (pretty sure 105) it is 100 plus octane anyways. I put a little in the bike just a little to clean it out

yup

they got it down to a science. And all that sounds familiar. Them engines get so hot they do want to shutt off. The exhaust are just pipes out of the hood. but when ya run on a budget I guess the mothballs are cheaper than the gas.

Hi all. I'm new here and was wondering if installing "colder" spark plugs would help reduce the need for high octane gas/octane boosters on higher compression engines. Would this work? Not cold enough to foul the plugs, but for example, maybe change from an NGK BPR5EIX-11 to a BPR6EIX. I'm definately no expert, just did some reading and it seems pretty simple. Too simple probably, I must be missing something??? Thanks

shovhd, you'll find somebody on here will have a definite answer. my opinion would be, it might help starting on hot days,but would not affect the need for high octane. i've built a few racing motocross bikes. it's fun to push a machine till minute changes make an improvement. to change heat ranges is good tuning, but no effect on the need for octane. welcome to the site. (is it summer yet?) gabby

LOL,summer? Not up here. 2 feet of snow on the ground.

The same reason diesel costs more than gasoline and costs less to produce...
Yeah, I've heard the old supply and demand story. There's less of it so it costs more. Funny how the oil companies work that...
