yes they did mother, there is one powervalve to each side of the egsaust port, its called the KIPS system

 

thats pretty cool. i was looking into a powervalve setup for mine, by trinity. Maybe later, of for a future project, kinda price. I hear its worth every dollar to.

 

maybe at the flywheel. not at the rear wheels. the banshee has 36 stock at the rear wheels and it was faster than stock tecate4.

 

yeah it doesn't have 43Hp. It love how everyone overestimates these 250's. The tecata was the fastest one but like roostthrower said it isn't even as fast as a stock shee. But it's not just the tecata. People think that the 250r in stock form was extreamly fast. There are a handfull of stock quads out now that are faster then a stock 250R. Most people also dont realize that a bone stock 250R isn't that great handleing in stock trim compaired to todays quads either. Sure modded it is awsome but stock lets not give it any more credit then it deserves.

Not trying to bash any of these quads either. If I can have any other quad other then my shee it would be a TECATE. So I do love these quads.

 

Guys - Like I said, the 1987 KXF Tecate 4 came from the factory with 43 stock horses. Just a fact. Has nothing to do with the a Banshee. [img]i/expressions/face-icon-small-happy.gif[/img]

 

I guess a banshee has 46 stock then

 

fast has nothing to do with hp young grasshopper

 

I have an 87 LT250 with wiseco piston .080" over Eric Gorr ported 39PWK reeds K&N no airbox Paul Turner midrange pipe sand skate II's. Yes it runs very good, pulls a little better than our piped Raptor, and a YFZ will just hand me my head on a platter.

Them old 250 2 strokes are fun to ride with the zippy powerband but they're yesterday's news for sure.

 

well since the banshee weighs a good 50lbs more than the tecate, I figured it had to make more horsepower. If it didn't it would be slower than a stock tecate. And it's not like the tecate was the only quad to have powervalves. lt250r's as well as the quadzillas had them. the motor yamaha should have put in the shee had powervalves. The rz350 made 55 hp stock and that bike screemed. 0-60 in like 4 seconds or something from what I have read about it.

 

just because it's faster doesn't mean its got more horsepower. Maybe the transmission was different, making it faster. I dont know any of the hp numbers or facts, but gear ratios make a big difference in how fast of quick something is,
