I decided it was time for an oil and filter change, however it seems that last time I topped up the oil I must have over tightened the filler cap, as today I could not get it off......... Needless to say, the bolt head is now rounded off. so two things: firstly, in the short term, can I get oil into the engine...

Hi, is there a particular type of grease that should be used to lubricate the wheel spindles ( are they called this, the shafts that come out to take the wheels off )? When repairing a puncture "in the field" it was pointed out to me that they shouldn't be dry so I thought I'd check if there was a c...

Hi Guys, I am swapping out my standard 14 tooth front sprocket for a 13 tooth one and noticed (as shown in pics) the current one seems to have rubber on both sides that the new one doesn't. Is this something I need to mount on the new one???? Or just an option that is not really necessary?? Thanks, Michae...

Hi All Firstly, although this isn't a ttr related problem, I'm hoping an electrical wizard will be able to help me figure out where I am going wrong! My DR350 got stolen a few weeks back. By some miracle the police managed to recover it after seeing some kids wheeling it about outside a travellers site....

Time for me to ask the dumb question, I brought a FMF Q4 silencer (not sure why now) it was a bit noisy but I fitted a piece of perforated stainless pipe with a blanked off end inside the back of the silencer and it works fine but I suspect I need to change the carb settings (although the bike runs ok). Any ide...

I went to adjust my needle and I realized the washer with the locking tab that sits below the needle clip is missing Is this a universal part?

Hi. The previous owner of my bike had the tank re-sprayed to a good standard, however he tried to apply the 'standard' TTR stickers to each side and it didn't go so well!

Hello, My 2004 ttr has developed a rattle. Its actually more of a jingle that happens when the engine is not under load. I wondered if it could be the clutch plates having worn tabs but any thoughts would be welcome before dismantling anything. Thanks Alex

After my first ever day out trail riding I was coming back along the main road and the bike all of a sudden lost power like it does when you run out of fuel. It then picked up and then did it again, so I switched the bike to reserve thinking I was running out of fuel. However this continued until I stopped at tra...

My bike was running rough and lacked power so it was time to sort it. When I bought the bike it always felt like it was not running properly although Ive not had it long.
