Hi all !! Just a couple of quick questions. I bought my ZZR250 from Sumoto (yeah i know.......) and recently had the first service done by them (only cause it was half price). I had noticed before the service that i had what i can only describe as a 'wurring' noise coming from the front of the bike when travelling at a fairly normal speed. I thought I had heard this somewhere before and was pretty sure that it sounded like the wheel bearings. I asked Sumoto to take a look and they said that they did and couldnt find anything wrong with the wheel bearings. Would you trust them or do you think they just didnt bother looking ? Im still getting the noise and its really frustrating !!!!! Secondly, I am only getting about 200kms out of a tank. Does this sound right ? I realise that my bike is quite old (1993 model) but my friend has a new Hyosung 250 and he has the same size tank as me (as far as i know, 18ltr?) and gets over 400kms out of a tank. Thanks all !
