I did take my spark plug out and this will be my last tank of super oil rich fuel. Saber is way way to heavy at 20:1 or so. I'm actually going to run Dominator at 30:1 now. |

| | Re: What a relief it is to start instantly... 30:1 should be more than fine.
I ran at 40:1 for awhile 500++ miles after break in with no problems, penzoil for air cooled 2 stroke engines.
I'll ad as a disclaimer, do not run you mix that lean, I had no problems, but still, better safe than sorry.
And yes, they do fire right up once they are broken in. Ain't it sweet?

| | Re: What a relief it is to start instantly... Stupid question: I'm on my second tank at 16:1. Is that too oil-rich?
I'm concerned about the wrist pin bushing. I was planning to never go leaner than 20:1, but it seems like you guys are doing fine at 40:1.
Oh, i'm using Castrol 2-stroke Motorcycle oil. It doesn't say if it's synthetic...

| | Re: What a relief it is to start instantly... I ran 24:1 for break in and now I run 32:1. I've had no problems. Tore my engine down yesterday for a few modifications and everything looked real good inside. I imagine if you run that rich you'll have lots of trouble with fouled plugs....................

| | Re: What a relief it is to start instantly... I put one oz of oil in the bottom of a one quart plastic bottle then I fill it with gas. that works out to 1 to 31 or so. The bike seems to love it. It starts much easier now and the compression seems to be a bit lower which is fine with me. It turns over much easier. |

Not to mention bigtime carbon build up in the combustion chamber and exhaust. Sticking rings are bad.

| | Re: What a relief it is to start instantly... I do my initial start with 24:1 with about one cup of that mix after that I switch to 32:1 and have no problems. On my first bike I tried to do the 24:1 for the first 100 miles as per the break in instructions that I was given, this accomplished one thing, I was fouling plugs left and right. If I run a bike on synthetic I use a 40:1 mix...Kelly

| | Re: What a relief it is to start instantly... Hmm, my plug is fine because I'm using a NGK B7HV non-fouling plug, but it does seem awfully sooty and oily. I'll go to the gas station later this afternoon and dilute the mix with another 25 cents of gas.

| | Re: What a relief it is to start instantly... LoL 25 cents you got to love it.
One thing that surprises me after I switched to 1 to 31 my smoking stopped almost completely. I use the cheapest oil I can find (coastal) and the darn thing hardly smokes at all. I don't know if a four stroke sounds different but that god awful lawnmower sound is the only thing that isn't great about it. | | Thread Tools | | | | Display Modes | Linear Mode |
