I have a 740 rotax with case and cylinders ported. Sled runs awsome for quick drags. But my concern is will my little bulk head cooler wich measure's 9" x 16" x1" be enough cooling for this modified 670 if i take it to the mountains or work it in powder. Just had complete bottom/top end rebuilt and want to make sure i'm covering the bases. Thx again.
Its a simmons 740 in a zx chasis, and was built with an aftermarket bulk head cooler put in it i beleive it's a alpine cooler not stock but still seemed small to me, so i thaught i would throw line out there to see if anyone else was runnin like this with no overheating issues or if i should add cooling. some one said the rev cooler would be easy to make work in tunnel.
