Screamin99 Posted August 2, 2012 Report Share Posted August 2, 2012 hey guys i just joined the forum and this is my first time posting. i picked up a 99 banshee a couple weeks ago and iv got a couple questions i couldnt find the answers too. First off i couldnt be more happy with my shee, will definatly keep it as long as i can, the only thing wrong with it that i found is that it has a whole in the lower case under shift shaft that has been patched. so that got me thinking about the cases and the entire bottom end and how much power it can handle. How much power can the stock clutch take befor lockout is need? how much power can the gears themselvs take? how about the entire cases? thanks Quote Link to comment Share on other sites More sharing options...
NickisGod Posted August 2, 2012 Report Share Posted August 2, 2012 (edited) everyone will have there opinion. stockish banshees are in the 30-35hp range. things you will need to consider is where are you riding and how you want to ride it. i like answering these types of questions because i been through it all and although my experience costed me thousands my knowledge is free. things i recommend to make your bike more reliable is 1) pancake bearing to keep your clutch rod assembly from welding 2) billet water impeller 3) a case saver (synthetic not metal) to keep from the chain poping again and causing more damage imo, the banshee needs control components before power mods. i absolutely hate the a arms and swing arm that yamaha put on this bike. i like lonestar products but agian this is my opinion. once u start hitting the 60-70 hp range u will need to address the clutch, a good set of fibers and heavy/light or a mix of both springs. the cases will hold up as long as u dont drop them on the shop floor. theres alot u can do to these bikes and alot more that needs to be done to support the power. list what you have done, list where you wanna be, some one will steer u in the right direction.

Trick2stroke Posted August 3, 2012 Report Share Posted August 3, 2012 Yeah, I can't begin to express how much I've learned and saved from the forum over the years, definitely an invaluable resource. As Nick indicated you should be much more worried about the handling limitations of the stock suspension. Focus on that area after/during doing the bolt on type mods.

gotta_goatsfast Posted August 3, 2012 Report Share Posted August 3, 2012 All good points. Stay away from cheap no-name aftermarket parts. Get tried and true stuff. Also, if you increase compression or plan on spinning it faster I would have the crankshaft trued and welded. It doesn't cost much and will make your stock crank plenty stout.

Screamin99 Posted August 3, 2012 Author Report Share Posted August 3, 2012 Thanks guys great information. I do mostly trail riding and some light moto, nothing crazy. Really all that is done to it is fmf fatties and a dyno jet kit with open air box. This year i do plan on getting a set of American star a-arms, havent heard anything negative about them yet, they are cheap and have a lifetime waranty. And i will probably be pairing them up with some fox floats. I havent givin up on the rear suspention yet, the only pain is how anoying they are for chain adjustments. Down the road i would probably get an American star 450r style swinger and who knows what shock. I do have some big ideas as far as the motor goes, i really like the t-rex cylinder and would match it up with a 4mil longrod crank and some bigger carbs and pipes. I am more interested in smooth power pull and decent tourque vs a wot drag motor. thanks for all the replies and good advice Quote Link to comment Share on other sites More sharing options...
NickisGod Posted August 3, 2012 Report Share Posted August 3, 2012 my suggestion to you is if u wanna ride your bike, stay away from aftermarket cylinders. These types of mods require patients and expirence. Not to mention deep pockets to support the mod. Consider porting on stock jugs. Get your controls squared away then go for power. As far as the trex goes. Not a whole lot of info on these cylinders, they are old and the cat cylinders arw cheaper and make more.power Quote Link to comment Share on other sites More sharing options...
Paulie B Posted August 3, 2012 Report Share Posted August 3, 2012 Just curious why not use a metal case saver? Quote Link to comment Share on other sites More sharing options...
Screamin99 Posted August 3, 2012 Author Report Share Posted August 3, 2012 im glad i brought up the cylinders. ik its not gunna be cheap but what kind of reliability issues will i be facing with aftermarket cylinders. I know a port job would do great, but lets be honest ill be happy with it for a year or two but them im just going to want more and more, its just how i am. By the time i spend money on arfter market head or machining the stock one, getting a quality port job, the usual bore/hone and new pistons i will be close to the coast of a new cylinder kit. plus i just have my mind set on a powervalve motor, iv looked into ypvs cylinders but all the electrical work and money will make them not worth it. I would like to read more about this cat cylinder is there a website i can go to? Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted August 3, 2012 Report Share Posted August 3, 2012 Just curious why not use a metal case saver? The metal case savers have been known to not flex enough when the chain hits them and have it'll caused the cases to break. The plastic case savers will flex a lot and absorb the chains energy saving your cases. Quote Link to comment Share on other sites More sharing options...
NickisGod Posted August 3, 2012 Report Share Posted August 3, 2012 here is the manufacture of the cat cylinders website. http://www.cpindinc.com/pub/part_list?manufacturer=3 you will need to buy the cylinder from a vendor though. u can get almost any size and configuration u want. i have a PV cat engine. it took me 3 years to get it working right. before u make a purchase ask the boards, dont buy then ask. im at 94 hp with a 485cc. i also have every mod done to support it. i spent around 6k.... the rz350 motor would be sweet but hard to find.

Screamin99 Posted August 4, 2012 Author Report Share Posted August 4, 2012 hmm that doesnt sound too apealing. hate to waste your time but what exactly was not quite right that you had to work on? was it just three years to get it set up how you like? if i was to do it i would just buy the cylinder around 400cc with stock bottom end (new crank and bearings done last season) and stock carbs with my fmf pipes. Then a year after or so i would do a 4mil, bigger carbs, biggers exhaust and aftermarket head. I know that year would be kinda wasting it but lets be honest im only 15 and dont have the most steady income of money hahah. Quote Link to comment Share on other sites More sharing options...
ban565 Posted August 4, 2012 Report Share Posted August 4, 2012 When you decide to go with a 4 mil I would recommed a Twistercrankshaft small block a little spendy however they can be bored and are reliable. Quote Link to comment Share on other sites More sharing options...
