Better to take your time and do it right ! Mine blew up on me . A valve stuck open and destroyed the piston and of course the head . I had to tear the motor apart down to removing the right case to remove shrapnel , but I left the crank pressed into the left case . Put it all back together with a new piston and cylinder and she runs fine now . Took me six months working a couple hours here and there .

I've wondered for a long time about ring positioning. Gaps should not overlap, very important, I get that. But what makes the rings to stay at their place? Isn't there a risk that the rings starts to move by them self when the motor is running?
@pacificmike9501
4 жыл бұрын
Not much. Cylinder bores are round. Rings have no reason to change their position. They break in and fit themselves. The design work that goes into piston rings is very scientific and very extensive. I once sat through a seminar on piston rings presented by one of the major manufacturers. It was way over my head.

The bar on the bottom, is it on the wrist pin boss? If so, it points toward the "cam side" of the motor. If there are no differences in those pistons, even the skirts? I question them. Get a lot of light on the second ring. Look for a taper on the inside. Look for that dot some more.

Mike, I'm at final hone on my Evo cylinders and both cylinders are between +.005" & +.010" oversize (3.509"). My +.010" hastings ring set leaves me with a .020" ring gap on my compression ring which is right at the maximum threshold (0.007-0.020" per the manual). Should I be concerned with that or go ahead and slap it together? Thanks for sharing! Love your channel!

Generally speaking the dot indicates installation of it facing up. This usually puts the "chamfer" on the second ring in the proper direction. If I seem a little vague, it's because again, go according to the ring manufacturer's instructions, get out your magnifying glass, have a look at that ring, and you'll get it.

Good "rules of thumb." But, I build a lot of "special purpose" stuff. By that I mean, it may be for racing. It may be a special piston. It may generate a lot more heat than usual for the components I'm using. I go pretty much by the manufacturer's recommendations, with a little more for the individual who's going to ride it.

@pacificmike9501

Personally, I would replace both base gaskets, and, not knowing what shape it is in (Evo cylinder bores last and last), I would most likely ball hone the cylinders, replace the rings, lap the valves, replace the valve seals, all the gaskets, and the umbrella valves. If the engine was in good shape, it will now last a long time. Let it warm up real nice before twisting the throttle real far and you won't blow base gaskets.

@pacificmike9501
Жыл бұрын
It depends on the piston. If it is a Harley Davidson supplied piston, use Harley's recommendation. If it is another brand, the manufacturer should give you their specification. This is all based on the fact that it is an air cooled engine and the fact that each manufacturer that makes pistons uses their own alloy which will have a different expansion rate.
