06 ltr-450 clutch or tranny problems

[creampuff]

I have a 06 ltr with 1st gear problems. When you let the clutch out to go the bike takes off, but as you give it gas it slams on in and keeps going. It feels like there is something broke in the tranny or something. This only happens in 1st gear. Any help would be good thanks

Mine takes off when you let the clutch out too. not sure what you mean by the 2nd part concerning giving it gas.
