8.5:1
The compression ratio of a 2004 KTM 250 SX is approximately 13.5:1. This high compression ratio helps improve the engine's performance and responsiveness, making it suitable for motocross and off-road racing. It's important to use the appropriate fuel type to support this compression for optimal performance.
Some of the engine's distinguishing features are 390 cubic inch with 9.6:1 compression ratio, four barrell carb @300 hphttp://www.hiperformer.com/featured_engines/for_390lb.html
The 1971 Chevrolet Nova with the 250 cid came optional with the Powerglide automatic transmission. The gear ratios on a OE Powerglide are 1.76 in 1st gear, 1.0 in 2nd, and 1.76 in reverse.
The ratio of 500 to 250 can be simplified by dividing both numbers by their greatest common divisor, which is 250. This results in a simplified ratio of 2:1. Therefore, the ratio of 500 to 250 is 2:1.
The ratio of 750 to 250 can be simplified by dividing both numbers by their greatest common divisor, which is 250. This results in a simplified ratio of 3 to 1. Therefore, the ratio 750 to 250 is 3:1.
most commonly either a 250 V6 or 350 V8, Although larger engines are often dropped in aftermarket
I have a 1993 Polaris 250 Trail Boss. It won't start. It floods out the carb. Could it be low compression?
Alot.
24. 150:250 = 174 : 290
To convert 250 seconds into minutes, which ratio could you multiply by?
Ratio = 250/300 or 5/6
your compression should be around 125-135 psi. for a 250cc polaris trailboss or trailblazer.
