front end shake
 

just had pair of tyres fitted and because I'm a lazy git had them fitted to the bike instead of taking wheels off myself. All seemed fine and dandy but the front feels a bit nervous, first put this down to being new tyre, but as I've now done 200 miles + am starting to think this is not right. The weights on the front wheel have different amount on each side, is this correct ? Any ideas ?

Tyre pressures ok?

33 psi front 36 psi rear, other than that check your preload and if all else fails take the bike back and say its had a wobble since they fitted the tyres

How old were the old tyres you replaced? You may just have got used to worn down, lazier profiled tyres, now they're the right shape it's handling as it should, but feels strange after being used to it before? Worth thinking about before worrying it could be a problem!

what do you mean by 'nervous'?

Re: front end shake
 

After I changed my OEM tyres for Avon Storm ST's (after the stock tyres had done nearly 12k), I noticed the bike was loads quicker at turning in and gave lots more feedback. Admittedly I changed the springs in the front too, but the bike felt loads different with new rubber on.

Different weights on each side isn't a problem necessarily I don't believe, just means the balancing of the wheel has changed with the new rubber.

Re: front end shake
 

it may sound silly but when you had the tyres fitted did they bother to strip the old weights off if any ? and are you sure they balanced it? Also check the torque setting for the front spindle

I fit & balance my own tyres.

My mate had some new tyres fitted to loose wheels at a local tyre fitters, so before he put them back on, I put them on my balancing stand.

They were a country mile out :shock:

I dont think he even stripped the old weights off, just fitted the new tyres.

Modern tyres are more balanced than cast wheels, so they get away with it most of the time.

I dont trust tyre fitters unless you can see them doing it.

Just doesn't feel quite right on slow speed corners almost like its going to give way. Also there is a very vauge shake though the bars.

Re: front end shake
 

I know what you mean. First thing to check is the tyre pressures, as mentioned above.

When you ride along, if you were to remove your hands from the bars does the bike continue in a straight line or attempt to steer off to one side or the other?

May also be worth testing your wheel bearings, front and rear, as I've had a dodgy rear bearing show up as a front end wobble before
