A nikasil cylinder means that the inside of the cylinder is coated with nikisil or chrome lined. If the lining gets chipped or wears off, it needs to be replaced to keep the bike running good

A nikasil plated cylinder can't be bored. You have to get it replated. I had a 97 cr125 and it blew up so I bought a sleeve for it and got it pressed in so I could bore it the next time it blew up.

if the cylinder is in good shape you do not want to bore it just find a piston the right bore thats in it now or maybe just rings

i heard,the bike is mint,give me your email ill send u pics and vise versa

 

[blaster99]

maybe he said 40,so every time i put rings i have to get it replated

 

[REEDracing94]

no u can put rings in without it getting bored all u have to do is put in rings unless the plating is messed up

 

[blaster99]

[REEDracing94]

dkbmx123@gmail.com is the email.

Let me know i wanna see the bike,we'll have to start a cr125 club on here. Hahah.

A Nikasil plated cylinder is pretty tough but also it does get scratched and when it gets bad enough you got to get it replated. I think it does have to be honed to match your piston but im not totally sure on that.

 

[crazy4wdracer]

Even a nikasil cylinder needs to be honed for proper ring seal.

 

[blaster99]

idk,im gunna call the shop

To give you an idea of what it costs. I bought a blown up '01 cr125 and had to get the cylinder fixed. The guy that I got it from cold seized it. To fix the cylinder, gaskets and new piston cost me just under $250. Its not a big deal if you have to get your cylinder replated.

you can so bore a plated cylinder, they just replate it after. had it done to a 76 yz 250

thats pretty good,how hard is a top end,with the power valve and everything

 

[crazy4wdracer]

It's still really easy, the only thing different you really have to do is disconnect the PV linkage. I just did the top end on my RM80 that has power valves. Piece of cake.
