Sudden loss of power, stranded on the highway!

[p40whk]

On the way home from work yesterday my 300i felt as if it just dropped out of gear as I was passing a car on the highway. I had engine as it would rev fine, no overheat temps showing and no other indications other than I could rev the engine and go nowhere.

I coasted to a stop off the highway and had to trailer the bike home last night. I'm assuming my drive belt broke but without tearing into it I really don't know what's the cause as I've never worked on scooters. The bike has over 12K miles on it so not sure if that's normal mileage for a belt but I do push it pretty hard (a lot of highway miles) so I'm hoping that's my issue.

Any suggestions to troubleshoot and if it is the belt, does anyone have any good sources?

  check with (powersportswarehouse.com )  or( stadium yamaha.com )  it should be in the 100.00 range,.  my dealer price was $189.00,   to hell with them,  as they are not interested in service  just sales,.  and they do not carry stock of any sort,. so it can take a month to get anything,.

If you have a 1/4" wrench, extension and socket set, begin tearing in. It's not too hard to get the CVT case open. A rubber mallet can be handy to loosen the case.

if you ever had a belt totally break at 65mph you would know it.hopefully you didn't do any other damage Good Luck

I tore into it this weekend, When I pulled the case off my first thought was "Where's the belt?" and "What's this rats nest doing in here?"

The belt was shredded so bad it looked like a rat had chewed it up and made a nest inside. I didn't see any damage and ended up having to remove the Variator to get all of the pieces out but I'm replacing the weights anyway so no big deal there.

Cheapest I could find a belt online was $129 +$10 shipping and my local dealer wanted $146 shipped so I'm supporting my local guy.

What sucks is how nice the weather has been the last few days and not being able to ride!
