The "Proof is in the Pudding"....

[AlisoBob]

I am always squawking about castor oil, proper jetting, cast pistons, and quality machine work... Why?



I popped my head off to modify it, and this is what I found...after almost 4 years of hammering on it....

PERFECT cylinder. No scrapes, no blowby, no black death, no "stop-sign".. hone makes look identical to the day I assembled it . I could not be happier!!

The studs keep making the camera focus on them, and not the cylinder wall. I'll try to get a better photo, it looks that good!


Exhaust ports are pretty free of carbon, sludge, or other junk that Castor oil gets blamed for.. Soot pattern is very semetricial, showing that the burn is well balanced.


Heres the best focused one of the cylinder, perfect!


Chamber looks great too....


See, paying attendion to details before, during, and after assembly does pay off!

That is sweet Bob. I agree, when you wory about the (important) details you see results like this.
I just popped the head off my 86 to put in a decompressor. Although it has not been ridden as much as yours, I was pleased to see similar signs, bore is perfect, head burn is nearly symetrical and build up was wiped off with a rag, ports are clean, no build up, no snot weeping out of the stinger or muffler!
When I ride, I do beat on my machines, so this has not been pampered trail riding bike, but I do ckeck the air filter regularily, change the oil, and fix anything as soon as it breaks, and keep it well adjustsed (most probably the most important as I find all sorts of things coming loose in that process.)
I will be popping the engine of the 86 out this week as the ice race sidecar needs it for exhaust and air filter fitting, along with some rudimentary plumbing for the single radiator.
