i really need some help
i have just completed a belt and roller change on my gts125 and there i something wrong! i wanted to change the rollers as they were a bit noisey, so after getting all the advice i could even off your tec' corner i was confident that i could tackle the job myself. i ordered the parts and as soon as they were delivered i set to work. i stripped everything down the belt looked fine but decided to change it while it was in bits. every item i took off was layed out on a board and marked eg. where it was from and which way round etc.... so no mistakes. all seemed fine and it. went back together like a dream, everything was finished tools put away, then i started it up, now the noise is ten times worse

what have i done wrong??? so i stripped everything down again thinking i had put something on backwards. rebuilt it again still the same..... now i was getting worried so i decided to try again but rebuiding it using the old parts, thinking the new parts may be wrong but its still the same. i am at a loss of what to do now so is there anyone that can please help me out. thanks dean.....
