Hi All,
 
I change my front wheel bearings again as i started to get a squeal from the front of my fazer, took the bike out and everything seamed ok, this was sunday, have gone down to Luton from Birminghham and the squeal returned on the M1, i am pretty sure it is not the bearings this time as i am not getting any judder through the brake lever & handle bars when i slow down which was happening before, how ever when i got to Luton i had a look at the rad and when sitting on the bike on the left hand side bottom pipe there is white corrosion which to me would indicate water leak (although not wet when i looked)......................is this a correct assumption?

If there is a air lock in the rad not sure how it got there without 1-the bike going on it's side or 2- not being carfull when changing the coolant again neither of these have been done recently, the coolant is coming up for a change and the last time i dropped the bike was 2 years ago in the snow when my foot slipped.
 
pretty sure it is not warped discs as when i checked these they were running true

ok final question if it is the speedo sender on it's way out how would i know as the actual speedo needle is smooth when going along?

Cheers

Stu
