I ended up drilling a 2ND hole in the chain guard. The bracket was more trouble than it was worth to make.
We went back to Pine Flats and Deadman trail.
The 60 tooth sprocket was impressive. The higher torque was very apparent as I climbed some very steep,loose rock trails. The TAV worked like a champ. I did have to mind the throttle as if I "goosed" it too much the front wheel would start to climb off of the trail. While the Hawg-Ty is much larger than the Coleman CT200u-EX bike Patric was riding, going over backwards is a concern now, the torque is that much stronger.
We rode 10.3 miles with 60% of it up steep grades.
His chain drive clutch got so hot the oil on the jackshaft chain was smoking badly. We stopped and let it cool for 20 minutes, and even then you could not touch it.
Once cool we were able to ride to the summit with no issues.
Patric did try to jump a mogul that had a 5 foot rise and didn't spot the landing. He landed front wheel first and went over the handle bars onto the trail.
No broken bones,but brother is he going to be sore tomorrow The bike suffered no real damage..
We rode from 7,235 to 8,185 feet ASL on the trails. 2 hours and 50 minutes ride time.
I'll pull the TAV cover and check the drive belt for wear on Sunday.
