A few years ago, I owned a 89 kx250 that was piped/ported. In repeated drags on pavement against my 87 shee that is piped/ported, my kx got the hole shot {2 or 3 lengths} untill midway through 4th gear, then my shee would smoke it. In sand and dirt, my kx would get an even bigger holeshot, but my shee would come on strong and close the gap at the end of the race. I miss that kx.

 

not meaning to sound like an @$$ but the KX must have been weak. My YZ is piped/ported for the most part, and it would kill any piped/ported Shee.

 

A Banshee with a good port job and set of pipes can easily make 60 RWHP. Which would make it more than a match for the average 250cc two stroke dirt bike.

 

that race doesnt sound right. The CR250 should of smoked your 250F no problem because ive seen it done.

 

and it did
