CR boot not fitting quite right

ok, got that cr boot and it seems like it gives me enough flexibility and length to get the carb to fit and make the intake clear the rear shock mount. But i have two questions.

1. the intake boot opening is larger than my carb throat so what it did was built up the outside of the carb with consistent wraps of electircal tape until it made a nice tight fit. looks like it will work and fit nicely but curious if anyone has ran into the same problem? Will this be ok to do or is it a big no no?

2. the new cr boot does not fit the 250R reeds quite well at all. Will this present a huge proglem or will is be a non issue. I have heard of someone using what they call a reed stuffer on another site. they say you use it when you install a cr boot onto 250R reeds. Does this ring a bell to anyone.

thanks again, garrett

I had to wrap tape around my stock carb, when I was using a CR Rad valve. never had a problem.
i no like the "using tape".... 'at stuff gets hot en sticky and tends to slide on itself. has potential to let the boot slip off. :huh:

I remember there being a discussion on another forum a few months back about CR intake boots. If I remember correctly, there is two different kinds of CR boots that work, but one lines up and works better than the other. It sounds like you might have the wrong one!

I think mine is a 2001. It's a little loose fitting, but seems to clamp down fine. If you got it from ESR, it is probably a 2001 also.
what size carb are you running on your quad garrett ?
You shouldn't really need a CR boot unless you're running a 41mm or bigger carb. You can fit a 38mm or 39mm in the stock boot. On my 265R I run a 41mm Mikuni TM with the CR boot. They fit like they were made for each other. I run the 89 CR boot. It doesn't have the reed stuffer like the newer boots do. The part # is 16221-KS7-830.

agreed .. your describing the down falls & unthoughtfullness of another RIGGED set up .. ...........stop the madness !! :blink:
i am running a 36mm at the moment. and i will be upgrading after glamis because like you said, rigged setup. Esr said that it is a good carb for that motor, but it just does not want to work the best and it is probably holding me back a little bit on power. And, i would rather use the stock boot, but it is so stiff and it puts the carb at such a bad angle that there was no way that i would get the intake on the carb. the cr boot gives me the flexibility so that i can get the intake on easily. it is also shorter that the stock boot and that helps. so im gonna run this crappy setup for a while until after new years and then i will really fix it right. Merry Christmas guys and thanks a lot.
i do not like your idea with the use of tape, as said before things get hot and sticky, could caue for the carb to fall off, or get an air leak, lean the thing out and burn it up......no likey!
yeah the tape thing was only a temp fix. i plan on upgrading to a bigger carb here soon. it ran good at glamis but was lacking some serious top end. i think it is that little carb on there.
