Did a quick search and only found tyre fitting? I have a part worn tyre I need to fit as the current tyre is (I presume) an off road tyre and badly cracked. I have a load of tyre levers, happy with the refit but just wondered the best way to get the old one off? Noticed there was talk on other threads of cutting t...

Google translator Hello gentlemen. I have a motor after refurbishment and I want to change the oil. Now it is Motul10w40 and is it good to give this one with a photo? And then do you have to rinse the engine? Is it better to pour Motul again? Thank you.

Does anybody know if a Raid loom has heavier gauge wire to the headlight than an OE? I believe the Raid bulb is 55/60W, is this correct? Also, what power are the Aus spec headlights with those big glass lenses?

Hi, my '99 ttr has started to leak oil (wetting) from the sight glass near to rear brake lever. I was looking in yamaha's part book in case there is a part but haven't found anything.

after putting a new timing chain on my ttr250 2004 model as it was stretched, and it has been starved of oil on the head due to the blanking bolt being left in (sounds nice running still) I thought that maybe the excess heat on the valves and cams had killed the stem seals ( but it doesn't smoke much on sta...

When start the engine or turn off the engine I can hear some metal knocking sound once or twice while starting and once while turning off. Is it how it suppose to be or is it something wrong? How to fix? Please advice. TTR 2008. Seems like sound comes from electric starter area.
