Last week I adjusted the intake valve lash that was out of tolerance. Gap between tappet and valve stem on the intake valve was 0.0015 inches.
The intake specification is to be between 0.005 inches and 0.007 inches.
With grinding the valve stem a bit with sand paper on a porcelain hard surface, I got it level ground after seeing I was going on a tilt at first. Also lapped both intake and exhaust valves in there seats and the result I ended up on target was 0.006 inches in the center or the range for the intake specification.
Saturday was out at Mendocino National Forest again at another location Stonyford. There was for Sunday a Enduro event and left although maybe trails would have some open not for the event. I was also maybe interested in watching, but they said there was not really much any place to see except a few areas. Also weather was supposed to have rain again, but it was clear.
As for my bike not restarting after it was run hard and got hot, this was not happening anymore and worked flawlessly. Only thing the area had also lots of rocky trails and dirt roads, so I found a few paved roads for short distance they allowed, but they are not that interesting. The mud puddles I usually avoided if I could, but near leaving time I went few times right through the center of deep mud puddles. These ones differed from think viscous mud type I had done before. There was maybe 3 inches of water and they 3 inches of viscous stuff underneath.
The past ones I rode through years ago had maybe 5 inches of viscous mud and if you turned the handle bars your sure to take a spill. I did not do that then or this time either. The bike is only 3.5 hp and no match for the very powerful trail bikes there.
Not very many people see a home made trail bike so quite a few people ask questions what is this. I though one person said something who was with a group of people that saw me riding there, it was this one person that said something like about finishing riding or being there the next day in the Enduro event. Only later I though maybe he was feeling I should have been going faster.
Going around banked turns and through mud as well as large rocky surfaces, I can't do as well as more powerful trail bikes. Those bikes have tire width 3 times that of mine.
I had good fun riding and the next day cleaned my riding gear some covered in mud. The bike I will clean some later, but though I did only pay 5 dollars to camp, the riding is paid by my 2 year OHV registration, and I got free under coating on my bike.
I have to shim my helmet cam mount it is at the maximum to point upward, but it misses seeing a lot higher up in view. I guess I am leaning forward and my helmet may be pointed down some. My eyes are looking up and I thought it was going to get good movies.
Maybe I will get that fixed soon, but I will get a link from Vimeo for an upload I am about to do of that road scene where I open the throttle up.
