Speedo vs. GPS

[68gmc]

Garmin GPS showed 190.4km/h which is 119MPH vs. the max recall. Pretty impressive accuracy!

Does Precision up the rev limiter to 10k or something? wow!

I would worry about floating a valve in this range no?

Just a spike spinning. Clutched for 9000rpm

Ok gotcha....nice

I end up liking 9 to 9100 myself(top) then it seems snappiest at trail speeds corner to corner. Revving any lower on top makes it much less snappy down low then.

Did you say you run stock primary spring(55/105)?

thnx

Stock primary spring with daltons set to 80 grams.

Thanks, thats what I thought. And really darn close to where Ive been getting myself.

Im in search of stock(like) rate spring for primary....Im not a fan of how the stock spring is so long and it really binds badly with mine, the glide washers help but would like to try to find something similar to 55/105 from aftermarket that is shorter overall.

Thanks for info
Dan

totally depends on conditions/traction. If on good ice, with good studs or very hard packed snow will little track spin..the speedo gets closer...once you start spinning...difference gets worse.

Mine's 3 to 4 out when running 125 to 130. gps vs speedo. 129" studded very aggressive on bare ice. Seems to be 2mph off when crusing 75-80. The other 129 in our group is the same.

That's a reconfigured gauge from Precision efi. You would have to send them your gauge.
