Fourtrax 420 starting problem!

I’ve got a 2006 fourtrax 420 at the moment, its the switchable auto/es model and the last few times I’ve tried to start it it just turns and makes a huge backfire noise and sometimes so loud that it throws a flame out the exhaust!!! So it hasn’t yet actually managed to start so I’m just wondering if anyone has any idea what the problem is?
Thanks

to torque or not to torque!

1992 trx300fw Ran great then clutch seemed to slip finally wouldn’t even move.
Re-adjusted the clutch and away it went.Today did same thing and i couldn’t adjust nothing on the clutch to get it moving.Took it all apart again only to find my mistake…….lesson learnt i could have sworn i torqued them,Got it all back together and seems fine again.
