Most newer bikes are Nikasil plated cylinders.

You do not bore Nikasil plated cylinders!!!!
You do not hone Nikasil plated cylinder, you just scuff them before putting in new rings (and pistons).

The 90 and the 109 have Suzuki's proprietary version of the Nikasil called SCEM. I am not sure about the 50, but ALL of Suzuki's off-road bikes have Nikasil.

I would be making **** sure you do not have Nikasil coated cylinder before going out and having them bored or else you'll be buying new cylinders!

When you have the motor apart, it would benefit you greatly to also check the crank, crank bearings, rods , connectors and journal bearings. If they are worn, you could damage the lower end of the motor by creating too much compression with the new pistons and rings. In addition, you will want to consider changing out the cam chain, guides and adjusters because you're going to have all of that off anyway to do the pistons. No sense in reinstalling worn parts. Lastly, you'll want to mic the valve springs and inspect the cams for wear when you do the valves.
I have been in contact with a shop that has been machining motorcycle engines for over 30 years and alot of local shops send their machine work too them as well as the Suzuki dealer I use. I was referred to them by several people, one of which used to race MX an quads. They will do a complete valve job and the cylinders aren't plated because the Suzuki only sells one size cylinder 83mm and they sell the pistons for that bore and they also sell a piston called an 050 which is actually .5mm os so you have to bore the cylinders to get the proper ring end gap. As far as the cams I'll do a complete first article inspection to check lobe height and duration. I will also take a close look at the rods / bearings, as far as timing chains they will be replaced as will the tensioners and guides.
I don't have the money to get another bike new or used so a few hundred dollars for the top end is just an investment for a few more years of riding, my bike is an 08' and I have just shy of 44,000 miles (hard, fast miles) I ride my bike like I stole every day so it's been very dependable, just uses too much oil.

Good. You did your research.
I was going to say if you can't figure out if they are Nikasil or not, take them to a machine shop that does Harley cylinders. Harley's are old school, low-tech, yesteryear machines and do not have Nikasil cylinders (maybe some of the new ones do). A shop that works on Harley cylinders can tell you what your C50's cylinders are and how much over-bore they can take.

I'm new to the site and my bike! And this is my first bike, I bought a 05 c50 and have done a little work to kinda make it different then others, I dropped It 2.5 inches, cobra pipes, new mirrors and levers also went with wide white walls, I love the bike just would like more power what if at all possible is the biggest piston I could go up to! I'd like to build the motor up over the winter! The bike will be apart for paint so figure try some motor work if possible... Any help would be great! Thanks

because of the engine being a water pumper the cylinders are sleeved and the sleeve is very thin, the biggest piston you can get is .5 mm oversize. Suzuki is the only one I've found, that will bump the engine size from an 805 to an 814 that wil make your C50 a C50.56 LOL
