what causes my yamaha raptor 350 to just randomly drop out of gear without touching the clutch or the shifter? and it sounds like the motor blows

 

In your other post, you said it only did it in 4th and 5th. Does it do this in any of the other gears? Say you're just riding a trail and never get out of 3rd. Does it do it then too? If it's just those two gears, I'd say it's a synchro problem. Either way, you're gonna have to pull the clutch cover and take a look inside.

 

it only does it gtoing from 4th to 5th and from 5th to six thats it and what is a synchro problem?

 

When did a raptor get 6 gears?

 

always has had them on raptor 350

 

I did not know that thought they only had 5 cool

 

A synchronizer is a part in the transmission that helps the gears engage smoothly and also keep them in place usually made of brass
