Had a miss-fire problem since I had the bike, thought I had cured it with a new plug and cleaning the plug seating on the head but it's come back again. I was wondering if it could be a faulty coil or plug cap - or anything else?. I can't see it being a carb problem - that's been cleaned out a few times. It mainly...

I recently had the seat recovered and when I look at the underside it is obvious there were once a couple of rubber (or similar) pads on the underside and there is a 6mm thread for attaching same.

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.

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...

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
