Hey Guys,

Looking for some advice on putting a used cylinder on my current Viper.
Long story short an exhaust stud snapped off in my center cylinder. Took it in to have it removed and the cylinder ended up being damaged beyond repair. Just an accident at the machine shop.

Brings me to this. My viper currently has about 2300 miles on it and I picked up a cylinder from a local salvage yard from a sled that had around 2500 miles on it (supposedly). The cylinder is in good shape w/ no scratches or anything like that....bore matches what I currently have.

So walk me through where you guys would go from here. Should I just hone it and put it on? Am I missing anything? What would you guys do?
 

As long as the bore of the cylinder looks good, i.e.: no nicks, chips gouges, it is probably fine to use. The NiCaSil material is very hard and does not wear much throughout the life of the sled, the pistons and ring material wear at a much higher rate. On my SRX engines, I honed the cylinder with a 3 stone hone which only cleaned the surface of the NiCaSil. If you want complete peace of mind, you could have the inside diameter of the cylinder measured with a bore gauge to make sure it is within spec for dia., roundness and taper. Give the cylinder a good cleaning and you should be fine.
 
agreed

Yes i have done a few of these myself.....if is in good shape no need to hone it....line up the rings and away you go....lots of good info on TY for that
 
Thanks guys! I was thinking that would be the case but it is always nice to get some affirmation.
One more question though and bear in mind this is inexperience talking. When you say line up the rings I am guessing there is a pin or groove in the piston that the gap in the rings goes in? If they weren't lined up, wouldn't it make it more challenging to get the cylinder on? Or is this something that is easily messed up if you are not paying attention? I'm just curious.

Thanks!!

I had the same problem. I just replaced the cylinder. I wouldnt hone it if it looks good, just clean it up with a brown scotch brite pad. Make sure gasket is clean and dry, use a little copper spray and replace. Make sure rings are lined up right. Here is the post from mine. http://www.totallyamaha.net/forums/showthread.php?t=80773

Listen Super1C..... If I had your time!!... You should always hone a cylinder to be safe. Given your amount of free time... you should know that.

Ha! :2strokes:
 
Hey Pete!

I may have to take you up on that offer!

I think you and I have actually met before at the test and tune in Byron Center. I think you may be friends with a few guys I know.

I'll Pm ya and maybe we can get something squared away.

Thanks!
