I have 2014 honda rancher trx420fa AT so I got the IRS also is Electronic Shift. So it is a high gear ratio then the SRA. I put the SRA rear gears in my IRS. Works awesome with my EPI stall clutch!….but now my wheeler won’t shift at high rpms. It will shift when I’m idling. But won’t shift at all if im moving. What the heck is going on? It’s not the es motor reduction gears. Already checked that. Anyone else out there had this problem? Do I need to put my stock gears back in? Please help!
