2012 tiger 800xc gearbox issues - jerks on 1st gear
« on: March 23, 2020, 01:09:58 AM »
Hi all!  Have had my tiger 800xc for almost a year. Bought it used 20kish miles. Started to have issue recently. First gear jerks every now and then and at times  few times back to back while in 1st. The rest of the gears are perfectly fine. I quickly go to 2nd when I can to avoid hurting anything else. The jerk is pretty intense almost feels like the 1st gear inside the gearbox is chewed up. Have anyone else had this kind of issue ?

Thanks !!

I'd check the chain first.

Yes, mine with 75k miles always starts doing that when it is in need of a service! Your valves need to be checked. Air cleaner needs to be clean. Stepper motor needs to be cleaned and lubed. All these jobs are fairly easy to do and all that information can be found on this forum.

Just weird that it only does it on 1st. The rest are fine.

It is the lowest ratio gear and the one that magnifies these type of issues because of its low ratio.

Copy. Are you referring to the possible bad chain?

All misfires or badly adjusted chain or another mechanical issues will be magnified in first gear.
I do agree with the others though you need to start at the front of the bike and go around it and check all the likely causes, chain adjustment and wear, front and rear sprocket wear, air filter cleanliness, clutch operation, etc. then get to the mechanical things like the stepper motor operation.

Also worth a check of  the cush drive rubbers in the rear sprocket and the front/rear sprocket teeth as well as the lock nut&shaft  on the front sprocket.
