426ex help

[2001 trx400ex]

I am buying a 426 pistion and i wasnt sure if i am goina go with JE or ross. Which is better and which is cheaper. I live in canada so everything is expensive. Also where do i get a 426 sleeve from. I am getting port and polish and stock carb 37.5mm and a custom made header. Other mods underneath.

the 426 is not a sleeve youcan buy it is simply the largest displacement the stock sleeve can be bored to. i would go with ross and i have not heard anything bad about them, but if you did a search on pistons im sure it will come up with results. "Which is better and which is cheaper." this statement is just plain weird because usually the more quality something has the higher priced it is. a port and polish would help alot and im not sure how a custom made exhaust would work seeing as it would be cheaper and better to go with a proven product that a company has somtimes spent months developing for the most power, in my opinion start with the 416 and then move up cause if your engine gets messed up and it is a 426 than you have to resleeve, with the 416 you always have more room.

the ross in my opinion is the best but i went with a JE

still with those two its almost a toss up:D

where do you buy gaskets for it or do you just modify the stock one and what is a thin gasket that will work for my setup? Also how much Hp should i b putting out. lets say it is a R4 race exhaust.

[2001 trx400ex]

and also how reliable is it.

I curently run a ross 426 and love it. The ross is a better choice IMO because it is lighter than the JE. You can get your gaskets at C&D, they have cometic flexsteel in a 426. Or you can get a modified steel stock gasket from sparks racing. I havn't had real good luck with the cometic.

i wouldnt use a cometic gasket on a push mower

[2001 trx400ex]

perfect but will i need a heavy duty clutch kit. I ride hard of coarse.

[2001 trx400ex]

Also how much Hp will i be putting out.

[Castor-426ex]

i dunno ill guess though........34?

i really wish i knew

[2001 trx400ex]

will i beat crapters cuz thats what counts.

[Castor-426ex]

dude its all rider

but so far i like what im getting from mine....

and im talking a huge improvement over stock

[2001 trx400ex]

I no that cuz i was beating crapters in hillclimbs lastweekend but i mean top speed in drag race with stock gearing and all of the 426 mods.

34-36 hp I don't think your going to beat craptors though. Through the first three gears mabey. Remember your racing a 426 against a 660. It's just to big a differance.

[Castor-426ex]

in my experiences a piped/jetted raptor doesnt give me any trouble till i hit fourth
and then i can ride their arse all the way in top end...but wait...i guess that could be partly due to my 36 tooth rear sprocket!! :eek: :D

[Natertot426ex]

I race my buddies stock raptor all the time and always beat him. Now a good piped raptor It won't beat. I love my 426:D

[Castor-426ex]

i give my 426 weekly hugs:D :eek:
