I called my local dealer today to get some advise on weather or not to hone my cylinder before replacing the piston and rings. My cylinder is Nickasil plated and you can see where there are shiny spots on both the exhaust and intake sides of the plating. I'm not sure if this is because i waited to long to replace the rings or not. Anyway, i asked my dealer how much to hone my cylinder to clean out the footprint of my old set of rings. He sais to me "don't bother". just throw in you new piston and tings and be on your way. You can still see the crosshatching all the way around, it just looks like there was a tiny bit of scuffing.
You know if i diden't spend so much time on Dirtrider.net, I probbly would have taken his advise. My cylinder does deffinitly need to be honed though before i put in a new set of rings. Anyway, I diden't think this was a very good peice of advise from a dealer that makes his living doing this sort of work.
I will be sending my cylinder and head off to Eric Gorr soon as i have heard nothing but good things about his work and figured i'd try the Mo-Betta porting. As well i will have him releve the exhaust bridge where there is a shiny spot on the lower third of the bridge where it looks like the rings have been rubbing. The plating is still there but it is shiny. I know Eric will releve this area when he ports my motor but doesn't this mean in order to do this he has to actually remove the Nickasil plating in this particular area. I guess it doesn't matter if the ring will not be touching the area there anyway.I wonder about the transition area between where he will remove the plating and where the plating resumes again. Could the plating begin to flake in that area? If theres no one that knows, i guess eric will answer theese questions himself when i send my parts in. What about the porting. Is there anyone on here that regrets having Eric port their Cr?
One other question. If Eric decides to take a bit of material off of my head or cylinder, will my top motor mount still fit properly cause the jug and head will be a little shorter?
Thanks
