2007 Honda TRX420FM Stalling Issues

[dibble]

Hi

We own two of these, and they both have the same mechanical problem

When they reach running temperature or after about 30 minutes they will idle but when you use the throttle they stall.

Any suggestions would be appreciated

Thanks

Has anything been done to them like an exhaust replacement?

there has been no repairs or replacement to engine or exhaust, just regular maintenance

thanks

Have they both been sitting for a while? Maybe change the gas?

what effect would a after market exhaust have on 420
