Time for a new cylinder?!?
Hey all it looks like my sweet '02 200 has eaten some sand. Prob going with PowerSeal to replate it since its fairly close and have a pretty good rep. I figure they have been in biz for a while, price seems fair and everybody else seems to not have issues. Any thoughts?
Heres a pic for laughs. Well, not really.

Re: Time for a new cylinder?!?
Those ports look very clean , almost too clean with hardly any carbon, & as for the piston that looks in good shape too albeit slight heat discolouration on the crown ...
Did the bike seize ??

Re: Time for a new cylinder?!?
No it was running well and has good compression. I just thought it was time for a rebuild and a new Wiseco. As fas as the ports, I agree they look good and the bike is in great shape. Im a little surprised to see the grooves but the electrofusion had a good run of 16 years.

Re: Time for a new cylinder?!?
How long have you owned the bike ...& is that a number I can see on the crown of the piston ?

Re: Time for a new cylinder?!?
Have had it for 1 year or so. I think there is a "C" stamped on the crown but no other lettering. Could that be oem?cornishwrecker220 wrote: ↑04:29 pm Feb 06 2019 How long have you owned the bike ...& is that a number I can see on the crown of the piston ?

Re: Time for a new cylinder?!?
Your title asks if it is time for a new cylinder. I would say no. I would definitely send it off for plating. I have read many positive reviews of PowerSeal USA here and on other forums. If I had to send off a cylinder for a plating, they would be on the very short list.
Thank you for participating on kdxrider.net.

Re: Time for a new cylinder?!?
Vossman: Your build is awesome and I have learned a lot. Great job on the bottom end. I think I can get away with not doing that right now. Post some pics of your cylinder when it gets back!
J- Yes I meant the plating. Have read a lot about PS as well and it seems you cant go wrong. Im paying the extra $20 for them to pull the studs too. I will have to decide if I want to get it ported when it returns.

Re: Time for a new cylinder?!?
I am sending mine out to PS as well. I called today for pricing on a wiseco and gaskets. Super nice over the phone. Btw, they are backed up a bit, 2-3 week turnaround.
Does anyone know if they actually machine match to the new piston, or just machine it to factory spec and shove a piston in the box? I didn't ask this to the woman on the phone.

Re: Time for a new cylinder?!?
Normally they try and keep it standard, if scores are two deep there just bore it out to get a good surface. They should advise you once they see the barrel what needs doing ect. I think you only need to worry about matching piston exactly if you have a racing engine, I think they allow a bit more clearance for the higher reving piston expansion

Re: Time for a new cylinder?!?
If they have a piston to go off of they will work off that size. The Wiseco KDX piston is 66mm, Wosner is 65.95 etc. so I guess if you don’t tell them what your gonna put in it they’ll just do it to a predetermined size.

Re: Time for a new cylinder?!?
Take advantage of your 3 week wait, and do all the other stuff you forgot to do. Like, work on the bike. lol
If you lend someone $20, and never see that person again, it was probably worth it.
