Yellow?   You mean grey, black and lime.  

Considering Doo has had 137 fully coupled sleds for about 10 years its good to see Poo catch up.  :lol:  

BTW I'm ordering a 137 or 144 in the Grey Lime and black.

Great sled for going in a straight line. Heavy mod F7’s should pull 118-120 on those surface conditions. 

A tuned up 700 is not getting by a modern 800 till 1000' or more

Tuned by you with a sprung crooked front end maybe. 

They just dont have the low end torque to compete on snow. Put them on ice and it evens the field a bit

I always smoked them off the line with the prox 660. They’d walk me on top end. A lightly breathed on F7 pulled 114-116 from what I could recall. I was always 2-3 mph off their mark on top. I did have a trimmed 14” track that may have done the trick, but I never got to run it.

I could care less about going over 110.   I just want to be the first to get there.  :thumbsup:   Once I'm ahead by so many sled lengths it time to hold up the old.......

Mine bone stock 03 would run 115 on snow. It would do 116 or so after all the mods but get there quicker. On ice it was a rocket.

We won a number of 1000' RR's at 110-113 on stock 03 F7's.   Clutching, gearing and a fuel pressure regulator.   Oh speed track with as few as picks as we could and still get good traction.   Changed with the conditions.

Making those top end hp was always a challenge. I think it was the narrow front cross section that helped the F7. I hated those things.
