Engine Upgrades


Recommended Posts

i bought my banshee early this january from a guy in rochester with a few engine mods and ends. well these mods wernt enough to satisify my need for speed so ive been searching the web on what proffesional mx and drag race people use for the engines. ive learned most people who are serious about thier shees use trinity racing parts witch cost ussaly more than the banshee itself. well i want to be serious but the thing is i dont have anyone to ridewith becuase all of my friends like cars. so i plan to make my banshee faster than thier v6 pos and show them up on a screaming two stroke.

 

what i need to know is..... is a override transmission worth it? why do they offer 2-5 1-4 and ect and what advantages does one have over another? i said if i were to get one id get the 1-6 so i can ripp through all 6 gears without my clutch. another thing is the lock up transmission. i understand thier function and purpose but is it needed when running a 500+cc enigne? id assume it would be, but i also want to know if i can run the lock up with straight cut gears? also what advantages do straight cut gears offer verse the oem ones?

 

Another thing i havent quiet understood yet is the advantages of adjustable timing plates. why/what do u use these for?

 

i will have more questions but i just cannot think of them atm. any help will be appricated

The override transmission will help out a TON but...you are not going to want a 1-6. By you describing what kind of rinding you do your going to need a duneable tranny. If you were to get a 1-6 you have to come to a complete stop to downshift it.

 

Lock ups are mainly for engines producing more than 90 horses i believe...its to keep the clutch engaged under hard acceleration and lots of power and yes you can run them with straight cut gears...straight cut gears are easier on your crank, from what i have read and been told...i still run the oem style so im not educated on them very much yet.

 

Timing plates are to adjust the timing of your spark, you advance it to gain more power and this is determined on your fuel your running, exhuast duration, elevation, and compression.

They offer different gearing with the override trannys for different uses. You need to talk to your builder and figure out what will be the best for your setup and style of riding. If your not 100% drag then you might want to consider a dunable, so that you can down shift. Lockup clutches are great and if you build a big motor (500cc) your gonna need one. AN adjustable timing plate does just that, adjusts you timing. You can get a little more top or bottom end with adjustments. If you really plan on a complete rebuild with all high performance parts at one time i would recommend buying a new bike off here. You can get something crazy fast for a little over 5 grand.

 

 

The best way to help you is if you post you current mods and even a pic of what your working with. And what you plan on doing.

well this is currently what my banshee's at. I have toomey t6 pipes, cool heads with ??cc domes, being run on race fuel (thats what the previous owner told me he was running) and some aftermarket clutch that i forgot the name to. it has other odds and ends but nothing of signifigant reconaztion. what i realy intened on doing is buying a trex 636cc big bore kit from http://www.bansheedepot.com/proddetail.asp?prod=TREX7670 with 41mm carbs to fuel it. ive herd these cylinders arnt as good as cheetahs and cubs but agian im not to concerned. obviously if i were to strap on 636cc to my stock tranny and cutch parts id fry up everything and would end up spending more money to fix it. so heres what im thinking at the moment

 

636cc trex bigbore kit

41MM PWK'S KEIHINS

Straight Cut gears

Lock Out Clutch

Override transmission

 

i went searching for a "DUNEABLE OVERRIDE" and turned up little to no results as where to buy them. everything just said "override" or "full override" witch is confusing me to hell. besides that i want to know what you guys think of my shopping list and if im heading in the right direction. as to what ridding style i do, i do alot of street and sand and occationly trials. so if some one can point me in the right direction maybe i can figgure the rest out on my own.

damn you better be ready to spend some money then. Earlier you said trinity is overpriced...and i completely agree with you but now you say your gonna buy that 635 trex kit...you do realize that 1800 doesn't include a crank or any of the machine work need to put it together, or any port work. I think you should do a little more research. Id bet that you would be more than happy with a very aggresive dune ported stock cylinder bike.

 

WCR cuts a damn good duneable tranny. 1-5 with nuetral down is a very popular tranny.

After reading the link i'm not sure if the crank comes with or you have to buy that too. Besides that you are talking about a serious motor. That is a FULL blown drag motor. I don't know if its gonna be trail rideable. To keep the front end down you are gonna have to have a BIG swingarm on that beast. By the time you get that thing built, tuned, and buy the other things you are gonna need you are talking some serious coin. There is so much more to making a banshee fast and rideable than just slapping a big motor in it.

 

 

With that said I will repeat my self and say "sell your bike and buy another one that is hooked up." In the long run you will save soooooooooo much time and money. I took my bike from stock to what it now over a 9 year period and have spent a lot of money. More than i am willing to admit to. I would recommend a 421 cub, on race gas. I bet it will have more power than you can handle. In the end its your money, burn it if you want.

First of all, what type of riding do you intend on doing? That is the first question you need to answer to base all of your builing on. I definately wouldn't recommend the mods you have listed for a bike you ever plan on trail riding. That setup would be more for a dedicated drag bike, what type of drag racing you do will determine the type of override you need ie: hillshooting, asphalt 1/8 mile, asphalt 1/4 mile, 300 ft. sand drag, 400 ft. sand drag ect. ect. Adjustable timing is a great way to improve your bottom end power, the more you advance the more bottom end you see...but, your octane requirements increase as you advance the timing as well. You say you are running race fuel now, with stock timing you will need race fuel or a mix of race/pump if you are over 150psi of compression. I agree with trex on this one, you should try out a good port job on your stock cylinders if you're not planning on it being a dedicated drag bike. You will be amazed what some different pipes and a port job can do. Basically, you need to answer two ?'s...what is your budget and what type of riding will it be used for.

Hey man, follow this link:

Jeff is a good guy, he can answer all your questions and get you hooked up with as much horsepower as your wallet can handle. He will shoot you straight tell you what you really need/dont need. To do a 421 cub the right way you better plan on spending 4K plus to get everything new. If that is in your budget go for it. I would stear clear of the trex as i have heard it takes a lot of work ($$) to make them run hard. Dollar for dollar everybody is going to tell you that the cub can't be beat. If you want to get nuts, have the 421 drag ported and throw it on alky. from what i hear 100hp isn't out of line for that combo.

Im pretty sure alot of people are running race gas and getting 100 hp out of the 421's....
