That part is the manifold, not the boot. The boot is the rubber piece from the airbox to the carb. If you get V-force reeds, you will need the manifold. If you purchase a Boyeson Rad Valve, it replaces the manifold with an aluminum manifold. As for fitment, go to service honda or motosport.com and compare the part numbers between the years. I bet it's the same part.

get the rad valve. it does away with the rubber boot and the reeds last much longer than stock in my experience.

there are 2 issues with the stock boot. 1) it cracks at the actual boot and 2) the oring that sits around the edge that contacts the actual reed cage goes flat and doesnt seal well and can cause air leaks here (my friends 01 did this). the rad valve remedies both issues.

You are opening a can of worms there. You'll find people on both sides on that one...

The vforce 3 comes with the intake boot aswell..

I haven't tried the vforce3 yet but have used the rad valve and love it...if and when the intake boot cracks on a rad valve u just replace a rubber cupler instead of the whole intake boot...

Not true. I think some of the ones for newer bikes come with the manifold, but the older ones, like for an 01 CR250 require modification of the existing manifold, in the form of removing the reed stuffers. You have to be careful while doing this that you don't damage the sealing surface in the process (I did this on my 02 CR250 oops).

Here's a tutorial on V force installation on a 2000 CR500. CR250 installation is the same thing.

That's for the delta 2 .......

Straight from moto tassinari

http://www.mototassinari.com/item/15...allation-video

Seems after some more research u r right not all kits come with the intake manifold boot......on their website their video shows it does .......but many others show u need to either buy it separate or mod your stocker

Could you run a gasket between the two when the "o" ring goes flat ? Just a thought.

i like a "factory" set up. if there are no gaskets and no sealers from the factory, i dont like to put them there.

with that said, my friend is not one of those guys and did use a sealer for his. He still had to eventually replace it due to cracks in the boot.

like i said, i think for this reason the rad valve is a superior part compared to what i feel is a really cheap way of building a cage like vforce does.

If you wanted a "factory" set up you wouldn't have a rad valve or V force. I've seen allot of people on various forums comment that v-force is cheap and a crappy part because it's made of plastic. Each part of a motorcycle has different characteristics required of its material. In the case of a reed cage, light weight and low thermal conductivity come to mind. Aluminum is heavier and has better thermal conductivity than plastic. Hmm. If aluminum was the best material for every part, we'd be riding bikes with aluminum fenders and number plates.....
