250-500cc Has this happened to anyone else

[mantrap]

This is the 3rd boot I have replaced in a season and a half, its a 2010 WR300. Has this happened to anyone else.

Design fault? You could use black silicone that is used for sealing windows?

Yep i,ve done 2 on my 2010 WR 300

 

[Croc]

did one on mine. Mine seized though, lucky it was under warranty. Did it at 800ks.

 

[mantrap]

Is there a solution to this or just change it out ever couple of months.

 

[Croc]

I was told by my dealer that there was a Faulty Batch, I say they are full of it & its old stock

 

[hogwackr]

I would silicone the crack.....just redo it every season or two. It won't hurt anything as long as it's sealed up.

Are you running the Keihin carb? If so maybe since it's 15mm wider it's putting extra stress on the boot. Just a thought.

 

[mantrap]

It's the stock carb. I had an 2006 wr250 that didn't have this problem will that part fit it has a different part#

My 2010 125 is doing the same thing. It's cracking all over. I've got the bigger Keihin carb on it. A new one should be arriving shortly for me. I'm gonna have a batch of the 125's made by Hot Foot Moto. I think they will last longer.

 

[NWRider]

Have they all been oem boots? If there is a bad batch then you could just order the same thing from anywhere that sells Moto Tassinari products.

I think it was 07 when the reeds were breaking which makes me wonder if when Husky orders a buch of stuff from Moto Tassinari that they do not get the same quality as what comes as an aftermarket part. That is how if goes with a lot of brand name parts when they are oem.

No problems with my 2010 so far. 1500 miles with Kehein and it hasn't caused a problem.

JUST REPLACED MINE ON A 2011 WR 300.

Black Shoe-Goo from the sports store works really well, too. It smells really strong so it must be good.

Mine needs replacing after 11mths 50hrs on a 2010 wr300, did anyone get it replaced under warranty?
Just put some sikaflex on for last minute fix. But seeing bout replacment this week.

Ha Ha that's a good idea. I've had poor kids on my tennis team that practically built their shoes out of Shoe-Goo because they couldn't afford new ones.

My 2010 TE 310 has developed a crack in the same boot (although though mine is a throttle body). I will be using some high temp silicone or sikaflex. I figure it is just a poor choice of materials, it should be more resistant to heat (As it contacts the head!).

Warranty ran out last month

 

[bax3]

Got my new boot today under warranty, plus 4 new carbon petals for the reed valves.
One of the tips was a bite rough when i took them out. So I sent them in with the boot.

I didn't have any trouble with mine.

It's a good thing that you look over your bike - that could be an expensive problem if not noticed right away!

 

[hawaii-rider]

???

What fuel are you all using?

Pump or PURE RACE?

I have stopped using pump with all my bikes due to the documented damage that the 10% ethanol does to seals, orings, brass etc etc....bad stuff.

use Aviation blue gas, low lead exclusively, especially my vintage race machines.

Just a thought....
