Topic: Stopped for too much smoke! 2 strokes beware

[grumburg]

Was out for a Sunday ride yesterday on my Suzuki T10. A local cop pulled in my drive behind me and wanted me to know that my bike was making excessive smoke. You know the type... 21 with a badge and a gun. I explained it was a 1964 2-stroke and it was supposed to smoke. Got a puzzled look...I said "2-stroke, you know, like a chain saw?". He said "Oh, Ok" and still had a puzzled look on his face as he drive off.

just tell them you added an S-LOAD of seafoam and are cleaning the carbs.

Way back when, I had just had my GT380 motor rebuilt and was breaking it in, had a cop pull over ahead of me and wait till I passed, I was going 45 in the slow lane on the freeway and he wrote me a speeding ticket because "he could tell by the smoke that I was speeding..."

I put Shell fully synthetic in my Kawasaki H1A.  After initial startup there is no smoke.  Worried me at first, 'cause a big blue cloud tells you that the pump is working!

I have been afraid to use synthetic or Amsoil in respect to 46 yr old bearings. Has anyone used this in old pre-mix 2 strokes?

I use either the Honda GM-2 two-stroke oil, or Golden Spectro.  Use the Honda oil in my NS400R, (oil-injection), and in my dirtbikes, (Pre-Mix) since it says it's for both injection and pre-mix.  Some oils are one or the other, (I cannot see how it would make a difference).

No problems from the Honda oil, and next to no smoke.  The NS only smokes when cold starting, but when warm, it's pretty clear, (except for the occasional blue puff when romping on it).  The dirtbikes always smoke a little, but I run 'em a little rich, around 32:1, maybe a little more, (sometimes 25:1).  Backing off though, and will probably settle on 36-40:1.

The Golden Spectro comes HIGHLY recommended by guys I know that race vintage MX, and push their machines hard.  Low fouling, little smoke, great wear characteristics.  I might run some in the NS and see how differently it smokes.

Next time ask him if he has 30 minutes for you to explain 2 stroke vs 4 stroke engines.
