OIL...

I think the frequency of oil changes is a big thing...I've seen various bike brands suddenly change the rec oil brand and rating over the years, even tho' the motor on a line of bike has not changed.

Often the rec'd brand has to do with money -as in how much will a company pay to have their oil put in an owners manual as the one to use...

Bottom line tho' - use a reputable brand. Change often.

i change oil and filter every 400km . have just done a bigend and was more wondering if im using the right weight oil ,bike does have about 6000km and it was getting used every weekend all bushwork as well it never gets used on tar. as it does get used andridden fairly hard im not dissapointed about the big end but just wondering now it has been rebuilt wether there is anything im doing wrond in maintanence?
