Good video guys, well done. Can't emphasize enough the importance of clean air into the combustion system, contaminants are what cause most of the cylinder/piston failures, oil leaks into the exhaust, etc. Keep those filters on tight, and keep them clean. I'm just finishing up a top end rebuild due to air filter failure in the first 70 hours of engine operation.

I honed a stihl Nikasil cylinder with a huge impact , deep socket covered in 3k grit sandpaper buttered up with diamond paste 😂. next time I hone a cylinder tho I’ll do it on the drill press so it’s more “ precise “ . send it ! Edit : muriatic acid helps get some aluminum off before I hone the cylinder

Why can you buy cylinders? I hear everyone say just replace it and some parts for my 2000 cr125 are hard to find I don’t even know where I’d look for a cylinder

Depending on how bad your cylinder is. If its plated or been sleeved. If the plating is just worn or damaged you can send it out to millennium tech to get it re coated

The crosshatch should be on the cast iron lining as well. -Charels

Hey RM,i did a top end rebuild have a nikasil coated cylinder..do i need to perform "Enigine Break-In" or are break-ins only for cast iron/retro cylinders?!
@rmatvmc
3 жыл бұрын
The break-in process is to help seat the rings to the cylinder wall regardless of cylinder type. So yes, it's a good idea to follow some sort of break-in procedure before riding to the engines full potential.

NIkasil is approx 0.003" thick. Non honing is very bad to do as nikasil is microscopic holes and even scrotchbrite pad will fill those holes and it willnot be like new again. kzitem.info/news/bejne/15d81myXkp15gXY

You are actually supposed to. It's a misconception because all the engine builders say don't hone it but they actually mean don't hone it like you would hone a steel or iron cylinder with a stone hone. Honing with a regular stone hone leaves dirt in the nikasil but an aluminum hone is safe for nikasil. The shops that replate hone with a diamond hone to get the cylinder into spec.
