The first gear seems to be a little sluggish on my 500 EFI, is this normal or not, when you apply power it seems to be a little slow out of the gates but drives out fine after that. Is this a gear ratio thing.
Pretty sure an EFI 500 is an automatic. If this is so then clutch engagement may not be as smooth as it is supposed to be. Check the rollers for flat spots on the primary clutch. While you’re at it check the belt.
