I put a 39mm fcr carb on my z450 (yosh motor )
What's is anyone using as a a rubber boot on the cylinder to the carb.
I tried to use the stock on that came with my z but the carbside of the boot is to small I heat it with a heat gun and sretched it and got it on and it came off after a couple of partices.
So I tried a boot off a yzf 450 it fit the carb good but the the cylinder side of the boot was to alittle to big . I put a bigger clamp on it and went practiced one day and it did fine and though a race this weekend I went and practiced sunday at a mx track and the clamp slide back and tore a hole in the boot.
Someone has to know something better that will work and know someone who makes something to fix this promlem.

 

some people use the 400 ex boot but u have to cut about a inch off it....

 

Don't 400ex intake boot bolt to the motor? both of mine clamp to cylinder and the carb.

 

not sure on that one but thats what they are using on others sites.

 

Hmmmm, UPP makes boots for raptors to solve that problem, and might make them for the z. They are plastic boots, and much better quality.

 

i took the stock boot and a dremel tool and shaved off a bunch of rubber on the inside of the boot to make it fit.
