I bet he is
I really don"t need to talk to him I just need to know one thing whats that 7010443 code or what Mr.portwork mean ?
All I want to know if set up for race fuel ? that's it.
Il take your advice and keep calling I guess.
Thanks you Skeans1 for the reply

 

its the serial number. first 4 are month and year, so july of 2010. the rest of the number is internal and documents the port timings, widths, angles and head shape.

Ok. Who ever did the machine work recently wrote on the wiseco piston box. Exhaust port measurements 41.72mm
TDC 22 1/2 Im thinking TDC means top dead center. Port timing 19.22mm .
So its been ported and more than likely I will have to change my jetting up.
The jetting in it now is main 165 -slow is 50.
Do you know if the port timing number and exhaust port measurements on this are small big or huge?????.
By the way THANK YOU for helping me out.

 

My guess is your mr. Port is mc port aka mx porting.

 

I think your rite he did want to set it up mc.
Thats why I think it was set up for race fuel.

 

I have old LRD cylinder on my R.
I was going threw my bill of sales and the dude I bought it from wrote it had Mr.port work.
But I dont know what that is ?

Are you sure, instead of Mr.port work, as in Mister, it's not MR as in mid range?
