Piston skirt shattered. Do i need to replate the nikasil coating or can i redone?

Recommended Posts

Long story short, i have a 2002 KX250 and the piston skirt shattered. I'm in the process of rebuilding the motor completely, top and bottom but I want to get it done in a timely manner where i can still enjoy the summer. I took it to our local motorsports mechanic shop here in town and they said i need to get the cylinder nikasil replated, which takes about 2-3 weeks because there so backed up. I wanted a second opinion and see what you guys think. Here are the photos IMG_6441.JPG.90f1b1f29a716932f09ab1afb59765e1.JPG

I wouldn't let just any shop replate my cylinder. matter of fact the only place I use is powerseal. certainly wouldn't let someone not known nationally for re plating do my cylinder. BTW putting all that time and money into your engine without getting the cylinder done would be ludicrous, not to mention probably result in having to spend a whole lot more on your engine real soon.

Doesn't look great.  Not necessarily due to the piston explosion.  Just looks worn out.

you will need to split cases as well and install new crank bearings and possibly conrod bearing on crank

millenium and powerseal usually have a stock on hand so they just send you a stock replated jug when they get yours.

where did you get that info. I would be pissed if I paid for a replate and got a different cylinder. BTW that's not what happens.

Straight from millenniums FAQ.. 

How can I get my cylinder serviced and back to me the next day?

We can ship cylinders from our core inventory out same day, utilizing our cylinder exchange program, but if you want your cylinder repaired normal turn around times will apply

^^^Don't have to do it that way but OP wanted quick turn around, core exchange would be the quickest.  It only works if your cyl hasn't had any modifications done to it.  I personally don't see the big deal if your cyl is stock and the one you get back is as well.

I just had PowerSeal do mine back in November, great job and best price. $180 for the plating plus shipping both ways. Getting ready to send my son's KX65 off as well.

Also as was mentioned several of the top companies who do plating offer a cylinder exchange program so you can get a cylinder back much quicker. However if you do not do the cylinder exchange they are replating your cylinder and sending yours back to you.

If you want quick I would stay away from langcourt, I had mine sent off they said 10 days but 3 weeks later I got it back for around $250 quality is great but the turnaround time was horrible.

I also had a very nasty gouge in the side of my cylinder as seen in picture. If you just need a replete and no welding it is cheaperreceived_1746118885403369.jpeg

Yes it is.  Millenium will give you the option to core your cylinder, or will replate and return your original cylinder.  Last one I had done was shipped to them on Monday, recieved a replated cylinder with top end kit on Saturday.  

 

Why would you be pissed if you're running a stock cylinder?  They all go through the same process, and all come out new and squeaky clean.

when I said "that's not what happens" I was referring to having your cylinder replated, not a cylinder exchange, since that's what was being talking about
