Looking good.

Hey, I have a brand new '01 CR250 boot that I'll trade you for your '00 CR250 boot. I dry fit it (no glue) and don't care for the fit of it on my Gen 3 CR250 based AF and wouldn't mind trying the '00 boot.

PM or email me at hrcracing@bellsouth.net if you want an even trade (i.e., I pay to ship to you and vise versa).

Thanks.

I read that the '00 boot was longer. Can you guys both measure your boots so we know for sure? That'd settle a problem for me.

From my workbench to the longest point on the throat, it's right at 7" long. I double checked it, probably closer to 6 7/8".

ill measure it when i get home. but if it is longer, ill trade you. ill just have to cancel the order at the honda dealer, again.

the 00 air boot is just a hair under 6 7/8". i guess there is no real difference in length then. i guess ill try to use this one.

Let me know if you decide to sell it. It's not a length issue on my bike, it's more the angle of the boot as it attaches to the carb.

I've got a '98 boot ordered but like your's, it's back ordered.

i probably wont sell this one, unless i find something else to work better. the angle is not the greatest with this boot either. with the carb and air boot on "straight" the air boot in not parallel to the front of the air box. im kinda thinking about fabbing the front of the air box out of aluminum to reach the boot without streching it and to meet at the right angle.
id like to know how a 02-on boot fits...

The '02 on boot is a flush mount versus the double lip design of the prior years. I have a new '02 boot and it's maybe a tad bit longer but probably not enough to make a difference.

On my Gen 3 250, it's a good allignment but, again, it's a flush mount and not really appreciably longer. If I wasn't so anal about using a double-lip boot, this one would definitely work.

After getting my '98 boot today, I think that that's what you're going to want to try. Measured as before, it's 7 1/16" long but the angle is very straight so it fits longer. I have to give it a pretty good push to get the subframe on.

Does the '98 boot bolt up to your gen 3 box?

thanks for the help. i was just gonna strech the 00 airboot to fit. my friend has a 98cr250, i might have to check it out.

You have to modify the box to accept the '01 and prior steel filter base and earlier double-lip boot.

I'm not really diggin' the fit of the '98 boot but I'm tired of waiting to fire this thing up so I'm going to use it until I get a '00 boot.

If the '00 isn't a better fit, I'll stick with the '98.

Cut out the box right inside of the bead that's used to allign the flush mount boot then use a Dremel tool to remove the bead. You then just have to drill out the screw nubs.

I really think it's going to work for you or at least get you a lot closer.

If you don't use it, I'd still like to buy the '00 boot from you.

Thanks.

I failed to mention, in my 4th gen build, that I'm running a reed cage spacer. I totally forgot about it. I run an 88 reed cage for more low end and it requires a spacer to fit in the cylinder. My intake boot is still 89 up with the rubber ears cut off because the 88 cage uses a stuffer. That's all you need for the 00 boot to work.

i finely got my X tank i won on ebay, brand fricken new for $56 shipped

head stay is done, air box is done, just waiting for the paint to dry so i can put the air boot on and stretch to fit.
CDI is mounted in stock CRF position, wires lengthened the 1" needed.
all my pipes are modified, the FMF gnarly fits like shit. it almost hits the spring. i probably won't ever use it anyway.

i was putting the plastic on and ran into a snag, i had to move the front mount on the right side panel to fit the 06 panel. we were having problems getting it to stay in place while welding it up, but it must have moved and i never checked it since then. it was about 1/2" off, so i had to cut it off and ill run down tomorrow and weld it up.

i was aiming to get it done tonight, its suppost to be 40 tomorrow

, and i want to tear up some snow. i guess ill have to wait till tomorrow to finish it up. ill post some pics tomorrow.

very nice! post some pics, I'm about to do 2 gen-4 crf250 conversions at the same time.

TJC510 · Post by **TJC510** » March 2nd, 2008, 6:43 pm

here it is as it sits right now

im ordering the parts tomorrow to finish it so i can ride it.
the only thing i need to do to it besides the parts i order is to clean the PJ carb. i was hoping to have a PWK by now, otherwords it would already be clean. ill probably have to buy a new one.

CDI box behind number plate

Rads modified

Airbox, i do need to pull it back apart and seal the boot to the plate, and the plate to the box.

my upper head stay

exhaust mounted with 06 side panel

Started in 3 kicks. one thing i noticed is it vibrates like a bitch. i didn't seem to notice though once i started riding it. there are a few thing i need to do to it yet, like new plastic and tires, etc, but its rideable.

HrcRacing · Post by **HrcRacing** » March 5th, 2008, 3:33 pm

Man, it must suck having to deal with all that snow. Anyway, congratulations on finishing the bike. Sweet lookin' ride.

TJC510 · Post by **TJC510** » March 5th, 2008, 3:40 pm
