I have tiny tach mounted so I can watch as I ride. the best I could tell was 6800 rpm at nearly full throttle. The max rpm tells me 7500 or so. Is this typical for low rpm on long runs? I would expect revs to increase to 7500 as it becomes unhooked. msd set at 7500 to 7800. Who really knows with setting msd. I was expecting motor to pull at least 7200 or higher moving through the water. Motor mods too numerous to mention. U name it I most likley have it.

Where do you have your tiny tach mounted? Your pitch of impeller will change your wide open throttle RPM as well
Tiny Tach mounted driver side of handlebar down low on hood cover. This took a bit to secure, had to remove top cover and route wires. looks good and is very visable. 10/16 hooker prop. Prop as I know is considered mild. (low pitch) which should increase rpm. Just wondering how many of you look at actual rpm #'s vs. recordable max rpm. My M8 Arctic Cat 153" snowmobile has tach max memory too but it's actual motor speed is a lot closer to recorded max rpm than the spread of 6800 actual vs. 7500 as recorded. I can understand hitting the rev limit as it unhooks and would give me a 7500 max reading but with all aftermaket products and msd. 6800 prop loaded wtf ???
That would be about right for a low port cylinder with a limited wet pipe although I would shoot for at least 7000. High RPMs come with high ports and dry pipes.
OooKayy So setting the rev limiter as high as it will go, I beleive 9000 would be just stupid. Higher revs may be possible with motor design but not likley I'll ever see on a a loaded prop? 62t 61x motor cyl ported dual 38mm bored. 185psi head. lightend flywheel MSD Protech wet pipe. and on and on.
