Banshee tore down, need advice on welded crank, engine seals, pistons

[SUBZERO25099]

Im getting ready to tear apart my 2003 banshee for the first time and im wanting to add a new welded crank, a good set of engine seals and gaskets, piston kit. 

 

Current setup:

toomey t6 pipes

there jet kit

air box air vents per toomey recomendations

Stock carbs

vforce 4 reeds

chariot 21cc domes

vitos timing advace key +4. 

 

im wanting a nice reliable trail machine that can get you in a little trouble from time to time.  i dont want a jetting nitemare or any reliablilty issues.  i was thinking of doing the following and i need your input

Vitos Super Stock Ported Piston Kit(supposedly 8hp gain, not sure nout that lol)

Welded crank

Good crank seals? need help on this

 

if there are any other mods while i have it apart please let me know.  I dont know who does a good welded crank, and what is a good brand of seals?  thank you in advance.

Vitos makes a good crank but I don't like there pistons because there too heavy I would get weisco prolights pistons and if you get a weisco top end kit you get gaskets and if you get a vitos crank it comes with bearings and crank seals I used these parts to put mine together and it runs very well and snappy

Ditch your timing key for a normal woodruff key and a timing plate. That helps with reliability. That way you don't risk shearing a junk key. There are several site sponsors that should be able to get your crank squared up and welded. I would try FAST. Also make sure to go through the whole bottom end and replace all the little OEM misc parts. Do the typical shift mods and maybe even have the messed with. Way nicer to ride when you don't miss any shifts. As far as the super stock pistons, that is a pretty good bang for the buck. I'd reccomend actual portwork though, but those are a good way to get more pep if the budget doesn't allow porting/set up. Seals, K&S or OEM.

Maybe see if you can find a different set of pipes. Other then that, seems like you have a good general idea of what to do. Let us know how it turns out.
