250-500cc WR300 opinions wanted

I went 55 miles on the stock tank. And still had at least 5-10 miles left in the tank.

Jetting was 450, 32.5, stock needle #2 and float set to 8mm. Elevations between 3500-6000 (I think!?) and temps in the 40's-50's. Bike ran excellent except for a bit of surge at elevation, which was easily fixed with the air screw.

I'd say if the jetting is close the bike is good for 60 miles in the woods and 70 in the open.

Good deal,......thanks man!

I seen the husky dealer today and he said that the bikes factory pipe is too restrictive and it actually comes with an open big front pipe.

Any ideas how big the difference in the power hit would be?
