Ieat4strokes Posted July 15, 2009 Report Share Posted July 15, 2009 my boss has a 400ex that runs low 4's in 300ft, so it can be done......but with the same amt of money you can make a banshee go alot faster, just my .02........ also if any of you ever wonder what a donkey punch is...... well sorry to say it but stroking just got it, i would def do any and everything to make his reimburse you or at least give you a set of unported cylinders Quote Link to comment Share on other sites More sharing options...

I AM NOT saying it can't be done. It probably took 5 times the amount of money to get it there than it would a banshee. It takes a ton of cash to get a 450 based bike to low 4s....a 400EX? I'd have to remortgage the house.... Quote Link to comment Share on other sites More sharing options...
ToomeySheeLE Posted July 15, 2009 Report Share Posted July 15, 2009 (edited) By the looks of that hackjob clusterfucking mess, I'd say the only thing that was ported was your wallet and your ass.. I've had my bad experience with local porters as well.. Taking my set of stock bore cylinders, keeping them for a month, refusing to let me put my own motor back together, and then when it doesn't perform and I take it apart, I find ZERO porting done, but its been bored out to 66.00... I found that to be an awesome deal for $350... no refunds and hangups we're all I ever got in return..

stroking Posted July 16, 2009 Author Report Share Posted July 16, 2009 Not trying to be a dick, but is that correct -7 on the timing, or did you hit the wrong button ??? thats right..a 4stroke picks up topend power by retarding the timing,and picks up bottomend by advancing it Quote Link to comment Share on other sites More sharing options...
2003LimitedBanshee Posted July 16, 2009 Report Share Posted July 16, 2009 thats right..a 4stroke picks up topend power by retarding the timing,and picks up bottomend by advancing it most all naturally aspirated internal combustion engines have a tendency to follow this trend... :wink: Quote Link to comment Share on other sites More sharing options...
