450r questions

[01boneless]

ok guys so the 450 im thinking about trading needs a radiator and the oil drain plug leaks (probley striped) what im wondering is there anything common to look for on these like on the ex timing chain issues. how hard is a rad to replace?

[06 Honda 450R]

Radiator is super easy to replace, but they also cost alot. It also depends on which drain bolt is leaking, if it is the transmision bolt leaking, it could use a washer, or if it is stripped, you would have to split the cases to retap it so the shaving dont go up into the motor.

As for what to look for, I look for worn out ball joints and tie rod ends, push the top of the tire in and out and see if there is any play. Check the oil, if its new, at least the dude thought of changing it, but also check the chain and sprockets. Just check all over for worn out bearings. Listen to the motor... etc. One thing to check to see how long/tough its been ridden is to look at the frame and clutch cover where boots rub and if there isnt much wear, then it hasnt been ridden very much.

[01boneless]

he said it leaked around the oil bolt so im guessing it needs retaped or helicoled i defnitly will not but it if thats the case. also how much would a rad run?

[Sjorge450R]

you can get a stock take off for under $100 (http://www.ebay.com/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=2005+trx+450r+radiator&_sacat=See-All-Categories)

As far as the oil drain bolt, tap it up a size and call it a day. Just make sure you drill from the bottom and use lots of grease on the bit so you can catch the oil shavings. Then flush it a few times with some cheap oil. Once your done, go rip on it.

[chronicsmoke]

Yah i'd just flush the oil a bunch of times after you tap it. Not such a pain in the ***** compared to splitting the cases..

Any pics of this beast?

Looks good from here, what kind of a deal are you trying to swing?

[01boneless]

trade my ex strait up. here is mine needs a piston he wants me to come up with a title but im not sure how to go about it lol

[chronicsmoke]

Thats a good trade in your favor! How'd you swing that?

I'd be on that like stink on sh it, haha.

[01boneless]

ya i know thats why im kinda weary but ima check it out!

[01boneless]

also what year 450r had the bad tranny? and should they make much motor noise (i dont want a pos) lol

[01boneless]

bump :)

[01boneless]

:D bump

[01boneless]

ok so i get to keep my prm bumper he keeps the ac and i get my wheels and razrs (new) and the 450 no longer has nerfs sound like a good trade ?

[mhsrb23]

id take it and 06+ have tranny issues if you ride them hard...theres no problems just wear out easier...need backcut

[chronicsmoke]

I would make that trade in a second. You're both taking a chance on it IMO. He probably assumes that the 400ex is bullet proof, but all of the issues you've been having, he might be in for a surprise, just as much as you could be.

[01boneless]

i hope im not in for a suprise my wallet dosent like them!!!

[hondarider421]

if maintaind decently the bike will be ok just ride it a lil and see wat it does make sure it shifts good and no deep thumpin sound (aside from the exhaust) and u should be fine there fun and great power

[01boneless]

well just got back from looking at it between 1-10 its 6.5-7 its got good plastic runs good took about 5 kicks cold frame was beat it was white but i couldent tell if it was a rattle can job or not alos had a shorty pipe lol loud!!!!!! so what you guys think??

[hondarider421]

If u like it thats fine but needs to have a lil fine tuneing it should start 1-2 kicks

[01boneless]

well had not been started it 2 weekes and was out of gas?

[hondarider421]

Just make sure it cranks easy after being ran and no deep noise clanking like noise and then u should be good to go

[finsteratv]

mine seemed good..till the starter clutches went on my first ride less then a mile into the trail:cuss: $$$$. but mines an 06.

[01boneless]

no starter here its a kicker !

[chronicsmoke]

I'd still do it man. You need to service them properly though. If you're unsure about anything, take it to somebody. I have NO problem paying my engine builder to do his thing. Everything else on the bike is simple enough, but I dont want to risk blowing the engine up due to some noob mistake.

this right here.
just remember with added performance comes matinence!

[blacknblue#2]

Id pull the filter on it just incase to check for shavings, more than likely if its made it this long it prolly dont have a crank issue but never hurts to check. Depending on how its been rode i would check the stress points of the frame. Other than that if its runs then there cant be much wrong with them. I always tear my 450's down after a riding season and freshen them up with new rings and and timing chain. If its a little tricky to start it could just need the valves adjusted. Which requires a shim kit on the 450's. No more simple valve adjustments like the 400EX lol. Wanna make sure your decompressor is set right also, that can play a part in the starting. Other than that these motors are very simple. I think i could take one apart in my sleep anymore. And if your trading stock suspension 400EX for it than you cant go wrong.

[01boneless]

yeah lol the valve adjustment suck if i get it ill pay you to adjust them lol

[blacknblue#2]

lol i could handle that. last guy i knew of that took his to a dealer got reamed out of 80 bucks to adjust them.....thats a little redic i think

[hondarider421]

Yea shops charge a fortune and hey man jw but wat kinda rideing do u do jw

alot of mx, and the occasinal drag race and hill climb lol

and black and blue i may have to take you up on that 50 bucks to cheap?

[hondarider421]

If ur gonna do a lot of mx i have a major upgrade that u can do urself or for really cheap that is a deff for mx

[01boneless]

whats that?

[hondarider421]

Lower the sub frame if he hasnt already and personally i can tell u the easy ceap way to do beside buying a expensive *** sub frame this is used to lower center of gravity and is cheap if u do the way i did along with many others but biggest thing i need to know also is year

[01boneless]

05 kicker with nmotion exaust, maxxis razrs, pro taper bars ,kill tether ,ac nerfs with the ,race pegs, prm bumper he says it has a ohlins frame but for one it looked like it had a spray painted frame not sure (dark) and did not know olins made frames? lol

[hondarider421]

Well idk about the frame but i do know that two major things u want is a linkage id advise gt thunder theres is amazing and the cheap track fix is cut and lower ur subframe if ur interested ill explain exactly how it was the best thing i did

[01boneless]

wel ill wait and see if i get it first you think it woud be a good trade? here is the 450

[01boneless]

my ex

[hondarider421]

Jw wat kinda suspension but yes hands down a 400 for a 450 deff i did a similar upgrade but i built my 450

[01boneless]

the 450r has stock and my ex has stock with 4 inch spacers all around (i know :blah: )

[hondarider421]

Ok well if u get it hit me up i have a built 05 i can give u alot of heads up and also have a few parts like aarms or shocks for mx and also can help u with that subframe i promise its worth it

[01boneless]

ok thanks dude

[hondarider421]

Just a lil heads up see if he changed the clutches and make sure agin no weird noises and biggest thing its a 400-450 swap it will be worth it even if u gotta throw a lil bit in it cash wise so just keep that in mind
