oil

When you order your motorized bike kit the manuel says to put 16:1 mix and than 20:1, well I use 40:1 and It runs great. My first tank of gas was 40:1 mix. Should I use 20:1 or 40:1

Ok, I know I'm going to get some **** for this but I ran straight oil now she won't start, it'll pop and fire every 3 rotations of the pedals. I took the head off, cleaned it out with gas and cleaned the carb. No plugged jet. I'm at a loss of what to try next, I've dumped the old gas and...

Hi there, Just purchased a pre-built 80Cc motorized bicycle off craigslist. The lady whom I had bought it from had had about half a tank in it already, so I didn't put in the first tank. When It came time for me to put in the first tank, I went to the gas station and purchased a 1+ Gallon...

if you can think of a better title let me know, want to start a sticky about amounts of engine wear after te1ardowns of using brands/types of oil at a given ratios. basically evaluating oil quality, I know it isn't practical to do a good side by side test with all the possible combinations, and...

I seen this stuff that you treat your gas with and its supposed to make your exhaust smoke smell better. I was just wondering if these are safe for a small 2 stroke engine. Has anyone used this before and does it work...

Ok, so what we have here is a 66/80cc china engine, no nomenclature(of course).First bike and I had it for maybe a week and was still tuning; just broke in...Tho all the while during initial break-in, it seemed to "hesitate" or misfire, which i credited to breaking in, and my novice familiarity...

is it safe or ok to ride an 80cc bike motor at full rpm even at a 16-1 mix?

Hi Guys, We have made a few changes to Bonneville Flyer chassis #3 in preparation for running the salt this year. This was originally a street bike and did not have the various bits necessary to pass SCTA tech inspection. It's been torn down, updated, and now is being reassembled. Seems a...

Hello fellow community, I own a 2 stroke engine, still in the run in period. I think i may have ran my engine too rich because the spark plug is definitely not sparking but the engine is not seized. i was riding it pretty far and i was going down a hill and it suddenly just bogged out and...

Thinking real hard about mounting my 79cc Greyhound engine vertically. Have the mounts, fabbed up a plywood plate, etc. But I am stuck on drilling and tapping the second oil filler hole. I have seen others use what appears to be a brass hose barb looking thing- are those 3/4" MHT threads...

At Fleet Farm, ran across something called Tall Timber oil. It seems to be a local thing, and it's made in Minnesota. It's intended for chainsaws and other air-cooled small engines and it only comes in packs of 2.6oz bottles to mix with one gallon of gas. A single bottle is $0.99, so I figured...

I have recently completed a B&S vertical shaft to horizontal shaft modification, was just wondering how it make sure I did it right and that I am not burning out my shafts. is there a smell or smoking that will occur if I did it wrong. also I was not able to change the flywheel and am still...

So me being new here and being to close to completing my first build. A question about oil? I've gone through the forums time and time Reading the thread about opti 2 oil and other oils but really I cant decide which i should use. Personal opinions are wanted please.

Hopefully the title will keep the riff raff out of this, but I doubt it. To start, for the record : I am aware that oil containers are in HDPE 2 plastic. This is what milk jugs/laundry detergent containers/plastic gas cans are using. Milk jugs are too thin and most people only have experience...

so the car club i'm on has a thread like this. here's the link in case anyone wants to know just what i'm talking about so to start of with... Rode my motor bike around my neighbor hood, and found a 'your speed is:' sign. had some fun with it, going past the sign.
