My 2001 yamaha 1600 roadstar backfires and cuts out just before I shift. It idle fines. it runs good between gears. It cuts out just when it get up in higher rpms, just before I shift.

Does the bike have a sidestand switch that cuts the power if the stand is left down? If it does, disconnect it and temporarily join the ends together and try starting....

SOURCE: Backfire after shutoff

With the key off and the engine "running down", the idle circuit fuel is still going to into each cylinder then out the exhaust. A hot spot in the exhaust can ignite the unburned fuel creating an explosion, ( backfire ). Let the engine run down to an idle THEN turn the key off.

Please rate this answer. Thanks!

gear selector may be jammed inside the casing or broken
check that the shifter is tight on the shaft!
check clutch adjustment
try rocking bike back n forth without using clutch while you try ******* the gear lever it may come unstuck
but get it looked at if it frees up!

SOURCE: Rpms speed up faster then bike does. Sounds like clutch slip.

You can adjust it by slackening the cable...unless it has hydraulic operation....Otherwise get it replaced before you do more damage..ie clutch dust and debris in the oil, so dont forget the oil and filter change too.
