How many revs does a Grubee Skyhawk GT5 put out at WOT. Im just wondering really... if i know the max RPMs I can figure out cruising revs, idling revs etc
Thanks,

I think 6000 is a nice number for a stock 66cc, They'll go heaps faster at the expense of parts, If you run it over 7000 too much something will break or wear fast. Unless its blueprinted, balanced and tuned then 8000+ is possible untill you rub the chrome off the bore...
The 50's can spin a little faster.
I run my 66cc between 5800 & 6200 depending on conditions or mood. I have a 35t sprocket BTW
With a 36t sprocket on a 26" high tyre 6000=31.5mph
With a 40t sprocket on a 26" high tyre 6000=28.2mph
With a 44t sprocket on a 26" high tyre 6000=25.7mph
I downloaded a spreadsheet for this stuff from some other place.

I just mounted a digital tach to my motor and your numbers match up pretty close to my 41 tooth 26" tire.... Getting closer to 6300 rpm`s at 27 mph....
see i must be doing something wrong because I put in my numbers into the gear ratio calc i get something like 1900 rpms
and when i put in 6000 rpms im supposed to be going 125 mph
is there a fool proof way (aka a "me" proof way) to figure out your speed without a tach... im looking into getting one soon but im interested in knowing now
