yeah any time you see a tensioner, it's always on the bottom.
harley primary chain tensioners are on the bottom, dirt bike tensioners are on the bottom, any time you see a tensioner on a drive chain, it's always on the bottom.
but having the tensioner on the top has worked for me on this bike....so if it aint broke, no need to fix it right?
yes, it has a spring pulling down on it to put pressure on the chain as it rotates.
also yes, that hard seat....it has padding, but not very much. I can usually ride for about 10-15 minutes before my butt goes numb, lol.
but hey, it's all part of the look and i'll sacrifice comfort for a cool look any day.
the tensioner on my o.c.c. is on the top as well, but it's a slider tensioner, not a wheel or a gear. it's just a wedge of delrin that's under the chain on the top side. this works great actually, and i drilled a hole in the delrin and filled it with grease. so, it self lubes the chain as it wears.
that ones been on for 2 years and it;s barely worn, and it does the job.
