Top End:
Here are some pic of the great workmanship on the porting, I would of liked to get some better pics but lighting in the kitchen is crappy
Stock bore ported cylinders
Best pics I could get of the porting, the enty where reeds go in could be smoother but when i took the engine apart some one did a weird modification and smeared JB Weld in this area trying to smooth the entry shape or something was really weird from dividers on the center port or around the side of the outer cylinder entry was filled and smoothed off I think tying to reroute the flow never seen anything like it before and took along time to get chipped and sanded out before I sent SHR the cylinder for him to do his work he smoothed them out some more and between what I didn and Him looks alot better than before.
Exhaust port opened up pretty good and smoothed out the side transfer type ports had alot of work done to them
46 thousands basegasket to be installed to raise port timing and shaved 20 thousands off the head to get 13.5 compression
like in a couple past posts I mentioned I was deleting or modifyiing my thermostat so here is a pic of my actual t-stat after I snipped the guts out of it and ground the edges down more smoother and leveler
Other side trimmed off and set in head right before I put the lower tube spout on
This is the stock bore MCB Coated piston top end kit, one thing that shocked me was the circlips were actually pretty easy to put in didn`t have to fight them like I have others got a rythm down I guess. these are pistons John sell that MCB and him designed.
PTO crankseal retainer installed loctited and torqued
Got the piston Installed, I installed the circlip in the inside of the each piston, dropped the wristpin cage bearing in 2 cycle oil I tested trying to slide the wristpin in the piston before trying to put on the rod and it started to slide in pretty easy but I went ahead and put both wrist pins in the freezer to shrink them and then they slid in piston even easier and installed the outer circlip. I really like the black outer coating its pretty slipper with oil on it and also like the holes in the sides of teh pistons for extra lubrication to the cylinder wall below where the ring pin is on the pistons. top of the black coating has small built in groves around the piston a few rows down for holding more fuel or oil for cylinder lubrication.
Base Gasket in place and Cylinders installed but not torqued down went over the the rings pretty easy
Washed cylinder down good couple times with warm water and soap to clean then wiped down with WD40 a couple times and then swiped in 2 cycle oil a couple times before sliding over the pistons
With cylinder setting on and bolts set up against them but still allowing movement of them I installed the Y-pipe with out the gaskets and easily tightened the y pipe down to hold the cylinders aligned and spare then I torqued the cylinders down in 2 steps like everything else that got torqued down.
Head installed with all new seals, Rave valves installed with new gaskets and Spring supplied by John, got he Stator and picups installed, flywheel plate and starter grabber part, just need to find the correct torque on the Mag Side Nut that goes on the crank the downloaded manual I purchased had everything and all specs I needed just couldn`t find the mag nut torque setting, got the starter adaptor ring installed, water pump housing, and the lower engine mount.
got the temp sensor and all electronics installed, I have deleted the the carb heater on this engine and also the Oil Injection a couple years ago so I made a block off plate for where the injection pump used to me,
Engine All assembled, here are a couple more pics of the porting with everything assembled
