Offroading with the dirt bike version, worked well. I got the all three belts tensioned and then tried it. It would hop at start if full throttle about an inch or two the front wheel off the ground.
Later I found the belt around the very smallest, 2 inch pulley between twin stacked jackshafts had the top edge shaved off. Small green particle of the belt were dusting the metal brackets below. I loosened the belt a little and it still had good grab power.
While I was later using it offroading it still had some of this dust from the belt but ever so fine a grit. More like a powder it was. I think I could just leave it now as it has worn in place and has stopped. No more debris from the belt.
I got an idea how long I can ride and then need to gas up again. It is not as simple as looking at would be even with the bottom seen from the inside of the tank. I had still a bit more gas than that. The outlet for the gas inside the tank I know has a tube up a little higher to restrict getting sediment if present. That means the gas must be above that.
At one point the engine died and I got it started and no problem running, but I would guess with the gas tank low, it sucked in some air in the line when on a bumpy incline and it needed to be purged out. That is not worth the effort to mess with, gas up before that happens. Walking back for that reason alone is not so smart.
With previewing the trail with a friends Yamaha 125 I was thinking it may be too much for my Briggs motor bike going back up the trail as the incline was a bit. The bumps were not to bad and the loose gravel on the trail you had room to go around usually.
I was cautious to where I turned around so that I had a running start. It did it fine. By the way there were some trails that I would get so far and just turn around. This even on the Yamaha 125 I would not have attempted. I'm not that good a rider. I saw a gully about 10 feet down and 25 feet across and knew the machine could handle it, but even if you fell and were OK, how to get enough running start when the flat on the bottom of the gully was only 3 feet across!
I guess in that case you use the engine to get it out while you walk besides the bike, your boots hopefully grabbing as well as the bikes knobby tires.
I know I did that with a 350 street bike when getting in an enormous pot hole on a less than well maintained city street. Then I had to stop for a red light and when I stopped my feet could not touch the ground. I had evaded falling over all the way, but there was no way to hop back on while in a rut.
One other part of a trail I turned around when I saw a groove about foot deep and a foot across, flanked by normal ground level just a foot and a half on each side. It was not a straight run either, it curved a bit. Trying to stay out of it was not the approach as I heard from another rider. He said he just when through it. My clearance on my bike is not enough and my pegs would probably have folded up as they are that type, but I would still get stuck.
Later I will change the memory size of some pics on my camera so that I can post. I need to load software on this computer I'm using which the other computer had that made it possible, but is now inoperable.
