staring crf450 project

[Martin Blair]

alright me and my dad started talking today about moding the 400 and he said if your really info racing y not make a complete race bike, so ive been thinking y not since i seem to have my dads support anyway.

Im figuring prices tonight and will be buying a frame soon, the crf450 will fit in a stock frame right, just need to mod the engine mounts a little bit?

[Narly R]

Man theres sooooo many people doing this!:eek2: But good luck with it I couldnt tell ya bout the mounts, but if your dad wants to pay for it all I say why not........?:D

[Glow Plug]

if you are gonig to be doing it then do it right, yeah you can use a stock frame with some modifcation but you will be better off in the long run with an aftermarket frame :)

[Martin Blair]

after doing a search and reading up on it i think i will go with a yzf 426 instead of the crf i lov ehonda but if i can get the same power, dont have to de stroke for half the price im with yamaha all the way,.

Is there a place only to buy yamaha parts like service honda? and what do you do about the radiators? buy one for a banshee or 250r?

[Martin Blair]

Also can you call up service honda and tell them you need a rollling chassis for a 400ex? i dont want to buy a used on i just want the frame, a arms, knuclks, tie rods i dont need another 400ex motor, or any of that.

[400exBro]

you will be happy,... i will also be doing this in the winter...

The yzf 426 engine has a TON of snap to it... it is a real strong bike, i love it... i rode forums bike, and it huals *** i tell ya...

if u were to buy a rolling chassy wouldnt you replace the a-arms, axle, swigarm, shocks anyway?

What you should do is buy a beat up 400, strip it down, and sell the parts you don't need. You can probably find the right deal if you are patient. Check ebay and cycle trader.

I would do that if I were you

I wished i could get a new quad and race....the only thing i race is turtles on my pos :)

[Martin Blair]

yeah im trying both ways, all seprate parts, and buying a used on on ebay i think buying a used bike on ebay or in town here would be cheaper, theres a guy with a 2002 for sale for 3600 in town.

Where do you buy new yzf engines? and are there any web sites that have plans to modifie the frame for engine mounts?

And for XC racing does the frame need gussets?

[Martin Blair]

I think i will go with a used on to start with then i will have everythign i need minus the 426, then i can mod the chassis from there, if i can pick up one with engine problems for 2k or so that would be great. It will also be easier to get insurance for it because it will have a valid vin # on the frame, even thought the title wont be correct.
