[NSRCA-discussion] Cleaning up a burr

[Michael Cohen]

Thanks, but I am just trying to restore the 160DZ I already have.  I still have another 160DZ and a 170DZ.

I got a YS160 for sale.  Includes everything you need.  Hatori header, hatori short muffler, nose ring, and hyde mount.  E-mail me if interested.  My e-mail is vicenterc at comcast.net.  The engine has new piston, bearings and ring.  I flew it last time around 1 month ago and is running very good.

Thanks,


Vicente "Vince" Bortone

The parts list calls the part a cam follower, but it is the same part number LH/RH.  I can see what looks like a nick right at the end of the bore, so I am assume that is preventing me from putting it all the way down.  I will call Richard at YS and see what he says.....  but just in case, anyone have a spare 160DZ case?

Mike,
 
I read that there is some uncertainty if there is indeed a burr inside? If there is...a tricky one indeed, as you would have to somehow get inside the cam chamber to remove it....hmmmmm. Is it the intake lifter or exhaust?
 
Have you checked that the correct lifter is in the correct bore? Dumb question I know, but you don’t want to run lifters swapped.
 
No real answer for you yet-sorry!
 
Tom

While assembling a YS160, I found a lifter would not seat properly.  Right at the edge where the lifter bore meets the crank bore there must be a little burr.  How can I get this cleaned up yet still maintain the tight tolerance in the bore for the lifter?
