91banshee Posted November 27, 2006 Report Posted November 27, 2006 i am looking for the holy grail of motors , i am power hungry , so much that i sold my banshee to find one with a 421 cub or something with a t rex powervalve motor in it , mine was fast but only ported fast , i want pull your arms off fast , and i want to trail ride it .for the guys who own 421 4 mm cubs how are they , another thing is i want to run the trinity 39mm single carb , the trottle wont rip your thumb off and it wont load up at idel on the trail. basicly i want all the motor i can get and still trail ride all day , i had 65 hp i want 90 to 100 is this to much to ask tell me it can be done Quote
Banshee4Drag Posted November 27, 2006 Report Posted November 27, 2006 anything can be done, just remember there is not really a happy middle with banshee's, either your hualing ass, high hp or your trail rideing with good hp....65 HP number's on a trail bike is not that bad...But a 4mill 421 is a good motor lots of power depends how you want to set it up...I myself never seen a 421 being set-up for trail rideing but good luck with that...It will be the hardest pullin trail bike i have heard of Quote
wesw Posted November 27, 2006 Report Posted November 27, 2006 there a millions post on this but they are not trail friendly. imo cubs arent. i guess you might be able to make them who knows. tripples and basically drag specs i guess kinda going in reverse. if its open trails might not be so bad.

csrmel Posted November 27, 2006 Report Posted November 27, 2006 sounds like you need cheetah cylinders with powervalves. or build an rz350 powervalve top end and have the cylinders ported and head worked on. Quote
Bansh-eman Posted November 27, 2006 Report Posted November 27, 2006 sounds like you really dont know hat you want...you want a beast but you want it trail friendly... you want pull your arms off fast but you want to run a 2 in 1.... a cub is diffenantly a WOT topend motor... its port timings are set for drag racing not tight trials... your going to have as Bigred says "a whole lot of the wrong kind of power" the bread and butter of the cub wont get to shine unless you got some long open trails... a cub dosent have a friendly bottom end... it almost feels like you have no bottom end and then viloently the powerband kicks in and keeps pulling... if you want a fastr and stronger bike... get a stroker with a nice port job and a strone ignition to carry the spark... you could have the beast of beats as far as motor goes but if you overlook the sspension your not going to hold that power to the ground and its all going to be in vien... spend the money and get yourself a top notch suspension as well...

BigRed350x Posted November 27, 2006 Report Posted November 27, 2006 Yeah... 421 Cub With a single carb set up for trails. That gets a big Cubs are not meant for the trails. :shoothead: Quote
