[SOLVED] numb fingers - 3000-4000rpm

[reddave101]

Now you've mentioned moving arms backwards or forwards and feels unsafe it could still be the front end and not engine..


Possibly headstock bearings have degraded?? Even if you don't feel any notching, if the bearings are degraded it can make the centre shaft loose which will vibrate up and through the handlebars..


And consider the forks. If the oil has degraded it won't damp correctly which will make it feel light and loose when moving as the front end will rise whilst accelerating but when riding the weight will make the front end sink and every mm of road surface will be felt all the way through the handlebars. Even if not actually felt it will be harmonic which will cause dead fingers and hands?


Very easy to change the oil in the forks. No special knowledge or tools are needed. All you need is a 19mm (spanner) ,socket for the top nuts, Allen key for spindle lock and stantion clamps, 12mm socket (spanner) for brake caliper bolts and Allen key for damper nut, flat screwdriver, small drill bit and small drill..Fork oil, oil seals, dust covers(if yours are gone) and new springs if want to upgrade. And about 1hr of time..sounds a lot but seriously it is easy to do and saves money..
