well i was looking to buy a hour meter to stay on top of my quad maintenance, i was intially gonna buy the DR.D hour meter. but then i cam across a hour/tach meters. one from moose racing the other from tiny tac.
the only reason i was intrested in the tach/hour meter combo is because i wanted to make sure my idle is set to honda spec, 1,700RPM. other then that i will never need the tach.
my quad is stock and i have never touched the jetting or idle, as is fr0m the factory.

i have a couple questions first,
- how accurate are these tachs?
- should i buy one?
- is idle that important to set, my e-start starts perfectly, and i dont wish on changing the idle anytime soon.

here is the moose racing tach:
http://mooseracing.com/catalog.jsp?level1=...amp;startPage=1

is says: "Firing patter: 1 spark = 1 rpm resolution in 10 rpm increments "


here is the tiny tach unit:

i have no idea which option to get this unit with? "this one Used on engines with one spark firing on each revolution of the crankshaft"?

id imagine they're somewhat accurate. i wouldent think they're acutally accurate within 10 rpms but hey who knows?
but me... i set my idle by feel, sound... so is a tach necessary, not really.

Tiny Tach has done a good job for a few of my customers clocking new builds....

I use the Trail Tech Vapor...

just get the hour meter, the idle should go by ear... it shouldnt lug during idle, it should be smooth and at a semi quick pace. it should hold its own during startup basically, other then jetting issues.

get the hour meter and be done with it
