well took the Dunerunner out today and checked out the new engine.


1 hour running temps was 140F..


on a Geko 101, it showing 39MPH GEARING:31,29,25,25


oh and lost a center dogbone pin..(no front wheel drive while checking for speed).


going to install the new center pin and then up the gearing to 35,25,25,25


just adding my 2 cents in the DuneRunner section


and looking for speed...lol

41.5mph running a couple hours rich to the point I can see light smoke at all times from the pipe. 813 carb 27.2 onb, lightened piston, blah blah. P2W!
 
yes i do have to pick up a 813 carb and dump this 667....

lords you might wanna check the walbro wt-990 it doesn't have the internal accelerator pump like the 813, they say it's supposed to be better than the 813.
