e-tec matt

I had a small issue last season with my 09 600 e-tec with a small hesitation coming out of a corner
and grabbing a hand full of throttle. My dealer told me they had a issue with the exhaust valve hoses when
they get warm the hoses contract meaning they restrict flow to the valve. He said the only way they would
replace them is to test drive it and get it to hesitate. The season is short enough the way it is i dont want to give
up my sled to lose riding time. He also said the replacement hoses are made of a more durable material. So
just wondering if anyone knows what material to use. Thanx.

The sled has good spark when air temp is warm but when air temp is cold i have a hard time getting spark.
When it does spark it fires right up and runs fine til you shut it down. It is either the ECM or the relay from
what ive been told.
