theredscout Posted November 2, 2004 Report Posted November 2, 2004 I have a 2001 Banshee with considerable mods done to it including a 5mm stroker. The engine was professionally built by white knuckle racing and has been rock solid. My problem is I have absolutely NO bottom end. I know with the banshee I shouldn't expect much Torque but my buddies banshee that is simply piped and jetted is much easier to ride than mine. Once my Shee warms up I really have to work the clutch to stay in the power. I jump on my buddies and one slip of the clutch and the power is right there. Don't get me wrong when we race I blow him away but only in a straight line. I recently had it dyno tuned and was impressed with the numbers....73hp..just NO and I mean NO bottom end. Any suggestions???? Quote
dlnoss Posted November 2, 2004 Report Posted November 2, 2004 One thing I have seen a few times is excessive squish clearance, particularly when the stock head is used with a top spacer plate sandwiched between two head gaskets. This may not be how yours is set up. Quote
lucky13 Posted November 2, 2004 Report Posted November 2, 2004 what do you got for pipes and carbs Quote
rebelbanshee2 Posted November 2, 2004 Report Posted November 2, 2004 was the porting adjusted for the stroke? if its just a plate at the bottom with no porting adjustment then that might be the problem. Quote
theredscout Posted November 2, 2004 Author Report Posted November 2, 2004 I am running the stock carbs but they have been taper bored. Porting was also done by white knuckle at the time of the stroker install. I am still running the stock reeds but he modified them. I am going to add the V-force reeds in the coming weeks in hopes of helping the bottom end out a bit. Any other suggestions?? Quote
broke Posted November 2, 2004 Report Posted November 2, 2004 build another motor That isn't very nice. Quote
dlnoss Posted November 2, 2004 Report Posted November 2, 2004 Is it spaced on top or bottom? Stock head or aftermarket head? Quote
FIRST BANSHEE Posted November 2, 2004 Report Posted November 2, 2004 your pipes could have alot to do with the powerband,you didn't say what you are using. Compression and timing will add some bottom end. Quote

sredish Posted November 2, 2004 Report Posted November 2, 2004 Have you contacted the builder to discuss with them?? Quote
roosthrower Posted November 2, 2004 Report Posted November 2, 2004 5mm stroker? I didn't know a 5mm stroker for a banshee existed. Are you sure your crank isn't just a long rod? Quote
Meat_Head Posted November 3, 2004 Report Posted November 3, 2004 http://www.twistercrankshaft.com/cranks.htm they will build it to whatever stroke you want. Running a stroker crank doesnt automatically mean you are gonna have great bottom end power, even a 10mm engine can be weak down low. Quote
