ATC 250RF project under way...Still at it!!!

[torker]

A new MOOSE steel shifter has been order, it will need to be cut and extended.



I've also bought some FLUIDYNE aluminum radiators, which are around 20% bigger, we'll se how those need to be modded. I think the trike has a better water routing than the bikes, obligating the water to flow to one radiator first and then thru the other before going into the engine. The bikes have 2 "Y's" that, IMO, is not as good. We'll see.



Also I got from EBAY a 2008 kick starter that, hopefully, will clear the frame without any mods, hopefully. If not that's an easy fix. What I'm needing now is to get a silencer to connect to the titanuim header. I think the 2006 CRF250 silencer will fit best, but that will need to wait until some funds become available. I still have a some welding to do as well as fabricate the front and top engine mounts from aluminum, which hopefully, I'll try and make this weekend or the next.
Welding is going on this weekend. I'm really pumped with this project!!!
I'll keep you guys posted.

Some other bits and pieces that I've been getting:

Rear stock axle: There is no budget for an extended axle so this is it, I got it for $50 and it came with everything, rotor, hubs, nut, everything. Great condition too!!! I've used spacers with great succes and absolutely no problems. So this one will use 5" spacers as well.



Brake lines: I bought these from "The quad parts guy" on EBAY. Made the long, front brake line and, altougth not inclided, he gave me the banjo bolts and cruch washers. $70 to my door.



Some more stuff is coming in, hopefully everything will be here next week.

Awsome progress so far. Looks like that yamaha fits really nice in that honda frame. Keep us updated and good luck on the rest of the build.

Uuhhhhh???? Yamaha????... It's a KX250F engine. Kawasaki. Although I'm sure the YZF250 engine will fit just as good. But I didn't find one in my price range. Yamahas are known to be the more reliable engines in this class, but less powerfull. The 250F engines put around 35 H.P. but are very, very heavy maintainance. Kawasakis are the best engines in this calss (next to KTM's) because they provide more tractable and usable power across the range. Not just 35 H.P. @ 13,000 RPM. And that was what I was actually looking for.

I think it's great. Good job.
Those radiators are still available new?

[NOS_350X]

That is a project i have been talking about for years. With a little work i think they could really put the hurting on a regular 250.

I actually picked up a WR250f engine a while ago, needs a crank thats why i never started it.

[torker]

We'll see. I'll put this against my other 86'R and see what happens. That will be fun. I'm sure hoping to get the results I want from it.
The wide ratio tranny should be even better. The Yammies are good.

Yes they are, but they are $479.00. Ouch!!!
EBAY is your friend. I paid $79.00

Nice score!
I seen the PWR ones for 449. So much money, but I might need them.

[factoryX]

I didn't know they still made them.

hey torker on one of my project to make a motor fit under the tank I heated the tank up ALOT moved it around with some wooden spoons (body man stuff) and made a 200x motor work in a blaster frame, I moved quite a large amount of the blaster tank around to make it fit but did it and no cutting or welding of the tank was needed, you might want to try that, oh I didnt use a torch just one of my heavy duty heat guns.

Hi there SYKO. Well, heatings is the alternative I'll be using on the next tank. I've already cut one up, hoping to weld it, but with the experience had by 250Rfan and Jason, I'll be heating one very ugly tank I have left and make it work, since there is not much that needed to be cut to make it fit. Do you have any advise for me in this fuel tank heating mod. endeavor? I've never done this before.
BTW, thanks for the suggestion.

FLUIDYNE radiators are in. They will need some modding, but I don't think it will be too bad. Hose routing may prove to be more of a challenge.




Do you think these will cool that HOT engine? It should help...

looks like a great project. Interesting to see how it compares with the old 250R

[torker]

Well, to tell you the truth, I think a 250R will compare, in terms of speed, To a 450R. No doubt. I'm doing this just to see what the 250F can do. And because project bikes are FUN (and very expensive, even without bling!)
But I'll put them both to the test.

There's been a minor set-back. My welder friend could not make it today, since I want the welding to hold (and look better than mine), I'm not doing it. I'm afraid it will have to wait another week.
I'll start on the radiators and a few minor details.
