I am in the planning stages of doing a topend rebuild, valve job, oversized pistons, and boring the sleeves to match the pistins .5mm over. I am trying to get an estimate for the boring but I need to know if the cylinders on an 08 C50 are plated or not? I did a search and found that some think they are plated and some don't think so. I NEED to know so if anyone has experienced a topend rebuild please let me know if the cylinders are plated. Thanks....

For what the stealer charged to do the top end on mine, I think its gold plated, Kurt.

I'm not sure about our cylinder material.

If you do need to replate it, this company is close to me.

Just curious, why do you want to replace the pistons?

I am rather interested in this. Please keep us informed of your progress. Do you have any ideas of kind of increase your looking at?

I am blowing thru a qt of oil in a 1000 miles or less depending on speeds. So the rings and guides are shot, since I will have the topend off I figured bore the cylinders .5 over and slap in a set of .5 over pistons. It takes a 805cc to 814cc. I talked to the dealer yesterday and he said they werent plated because they sell the o/s pistons the barrels have to be bored, Suzuki wouldn't plate the cylinders because the cost of replating would not be cost effective on a bored topend.

I am planning on doing this on my Christmas Vacation, but I am in the planning, collecting parts stage.

DITTO:

Its looks like I'm going to be keeping this 42mpg bike for a while longer so a top end may be needed. I just turned 10,000 miles yesterday.

cali-c50 did you "break in" your engine when it was new and if so was it done by the book or did you ride it like you stole it?

I broke mine in with wide open throttle up to a resonable shift point so not to over rev. It might use 4 ounces in 3000 miles, but I don't think so. You know how those stupid sight glasses are. LOL

That's about the same oil usage I was having, even after the top end rebuild and I did run the engine pretty hard while commuting. With the engines revving higher at sustained highway speeds and from other threads I've read over the years here, adding oil seems more the norm. There is no noticeable increase in power with the larger pistons, but the engine still has plenty of get up and go.

Yeah 805 to 814 isn't a big enough jump to notice a difference in power I am guessing that the cylinder walls are worn enough to have to bore them instead of buying new (used) cylinders.

How much cylinder wear is considered "too much" to hone (not bore) out?
I'm guessing .008-.010".
I would not buy pistons unless they were burnt or scored if the cylinder wear is less than above question. I use an old piston ring to clean the ring grove.

If you could, take some pictures of the pistons and inside the bore.

I'm very interested in learning how much cylinder (ring) wear inside the bore.

What's your total mileage?

You want to be careful when doing the top-end rebuild on your bike. 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.
