Installed mine today, it is the one from Dennis Kirk (1-7/8") part # 40-7646 for $69.95 plus $6.95 shipping.
I mounted it at the bolt that holds the right turn signal assembly. The tachometer dial is almost straight with only a degree or two rotation, hardly noticeable.
The zip tie that holds wires and front break hose together, needed loosening in order to mount it. No need to cut it, just lift the little lip that sticks out of the 'cube' and it will loosen. It can be tightened in place again after mounting.
Also I needed to temporarily undo the break hose from its holder at the left fork, about halfway down, to loosen it and to make space for mounting the tach. Now the brake hose sits snug around the tach.
See pictures below. Sorry for the crummy picture quality, it was getting dark and I didn't use the flash.
Thank you QuimRider for the inspiration :2tup:
Thank you TrykeMike for suggesting to power it from the horn +12V, it works like a charm and the only wobble at low revs is due to actual rev fluctuations. :rawk:
And thank you JonathanIQ180 for finding that nice little tach at Dennis Kirk.
