need help decided ASAP

[TRX01]

ok well i need to rebuild my engine and i originally planned on a 416 kit and a buncha goodies and then my dad decided he wanted to do a 440 kit well we got to talking about it today and talked about the pros and cons and now we cant decide on whick kit to do.....and he said its all up to me.

so what kit should i do
maybe list some pros and cons about the kit......i cant decide

416cc
426cc
440cc

[josh25ex]

all i have to say is go big or go home. how may hours can u ride on each kit before u have to change the piston??

[TRX01]

good question

416 with a bunch of goodies!!!!
very comparable to my 05 450r

[lester985]

416 or 426 with a bunch of goodies

[TRX01]

ok i think thats what i might do....i think yall just made me want to eliminate the 440..more opinions?

[honda400ex2003]

i would try out a 426 if i was going to do it again just to see what it is like. it is tough to decide. lol. unless you have all of them lined up and can ride them it is hard to tell which is actually better. even different compressions that may be built different run different. mine can run with stage 2 hotcam 11:1s with my setup in my sig. it may run better than most. I have no idea. they can be broke in different and make a huge difference in performance. lol. sorry not much help here. steve

[TRX01]

well actually i just talked to my dad about it again (he is gonna by the 416 kit) and im gonna buy the stage 2 hotcam, valves, seals, and valve springs......so were doing 416 kit, 11:1 comp, stage 2 cam, new valves, seals, and springs, and then all the stuff i got in my sig now........tell me what ya think?

[1999x400ex]

good choice goin with the 416. i have this kit on my bike now and its really quick. a well tuned 416 will hold with a 440 anyday:devil:

[honda400ex2003]

port and polish it a bit and it will be a runner for sure. :eek2: that will be a very nice setup. steve

[TRX01]

not enough money

[gtt416ex]

you'll have the exact same setup as i do, i'll highly recommend HD head studs, i blew a head gasket six months after my rebuild. you'll be impressed with the power it puts out, very comparable to a stock 450R if its done right

[TRX01]

sounds good man.....not the blowing head gasket part just the power out put part lol:macho

get a dremel and an end. you can clean it up a bit to get the ridges out and do it a bit of justice. wont take too long either. steve

[TRX01]

oh heck no steve..ahaha i wouldnt trust anyone except a proffesional porter to do that, once you start cutting there is no going back and thats something you can really mess up.......now maybe if i had an extra cylinder i would try it but deff not going to do it myself.......

ok i was looking at the kits on ebay and all of them 416 with 11:1 kits come with namura(spelling?) gasket kit, are they any good? my dad was look for cometic gaskets but none of the kits come with them so lets talk about the namura gaskets?

[honda400ex2003]

I personally would not run a namura but i have heard good things about them. about the porting. i am not saying to take off any material. there are ridges inside from where it was cast. these can be cleaned up by just about anyone with a steady hand. no material removal except those. it may not make much of a difference but why not do it while it is apart. it is like the header welds does it make a difference or not? lol. take the butterfly out of the carb for the summer too. it all starts to add up a 1/4 horse at a time lol. for a good example. steve

Stay away from namura gaskets, the pistons and such are fine, but gaskets are no good. Blew a head gasket within hours of a fresh start/break in

[TRX01]

ok ill just order the 416 kit with gaskets and such and then just buy a new set of cometic gaskets for a 416

[lester985]

look for 87mm piston kit its a 416 ebay has them with out the gaskets

[mineralgrey01gt]

im going to port my own head, not just cleaning it up, going all out on it to see what i can get out of it, of course im researching this a ton before i start cutting it. ALso when i do it im going to port the intake boot along with it. I was looking at the head and there is a good bit of material that can be taken out at the outlet of it so thats getting cut some also. Ill have plenty of pics and am posting a how to (might even do it for you for a small price after i get a few under my belt)

I think the 416 is a really good choice. I bought a COMETIC gasket kit off of ebay for $35 shipped, not bad at all IMO and it works with the 416 pistons. We will have pretty much the same setup, yours may be together before mine so if it is, post up and let us know how it runs with that done. If it is comparable to a 450 without the port work, that just makes me more anxious to get my port work done

[JOHNDOE83]

just remember if you go lower then a 440, everyone with a 440 will have a bigger motor... mine never overheats, starts easily, super reliable, tons of power, revs out fast as hell, I wouldnt ever go lower in bore size.

Modded banshees, who cares... mines just as fast as 400cc stroked banshee from "trinity" in a drag race.

[TRX01]

sounds cool guys......

[josh25ex]

put on the cfm aluminum air box what a big difference with a open air box more low end power and mid range power and it looks pretty sweet if i know how to post some pics i would put them up. deff a good idea to by one makes putting the plastics on very easy and has a throaty sound. wants to wheelie 1st 2nd and 3rd gear. im in love lol. one of the best things i have boughten.
