You don't feel any crest there. Only the color left I guess.Google "ring ridge"...
Well, the most critical part of the cylinder is the upper 1/4" of the ring travel, where the compression and combustion pressures are the highest, up to 800psi.
Just something to consider. It'll probably run just fine like that.
But, the proper method involves precision measurements of the cylinder bore, looking at diameters, egg-shape and tapers. Then setting ring end-gaps to match...
Yes! In fact, this publication has inspired me to continue this work. The workshops in my area didn't even know that the cylinder had to be measured to rectify, so I better do it.Have you read this?
Yeah... should have been clearer. I meant no sideplay between the inner bushing and the bronze bushings.Hold on there, friends! If there's no side play on the swingarm it will lock up when you torque down the swingarm axle to spec. You need to be sure that the inner bushing (tube) is longer than the combined width of swingarm and bushings. The tube-not the swingarm bushings--needs to lock against the thrust plates (AKA grease seals) when the axle is tightened. A quick search will show procedures for measurements and installation.
It looks like he did. Looks normal to me.The base gasket in your pic appears to be installed upside down and backwards. It only fits right, covering all the sealing surfaces, one way. I hope you corrected that before putting the cylinders on.
