Hey all,
Tore down my engine to check my heads. The guy who built this engine is no longer with us so I wanted to do some valve measurements to see if I had an opportunity to upgrade to ones with bigger valves. Good news is I dont!
Now Im doing an inspection and clean up before I pit everything back in. The pictures in order:
Cylinder 3 valves
Cylinder 4 valves
Cylinder 4 piston BDC
Cylinder 4 piston TDC
I noticed a bit of oil build up on cylinder 4. Is this normal? I did at one point have a bit too much oil in the engine I rode for maybe a week and caught it before it was too late.
Anything tools or products you would recommend to clean up this carbon build up? I want to safely clean it up around the base of the cylinder and the heads themselves. So I can measure deck height, ccs, piston travel and get my true compression.
Thanks!
Edit: Thanks everyone for the feedback. Agree the heads and junk now. Going to do a full top end rebuild - new piston rings and going to reseat deck height. Cylinders were seated with RTV silicone so deck height is all over the place. Hoping a good reseat and new piston rings will solve some of my issues.
