There are a lot of urban myths and quite a bit of folklore about bearings and the best make, type and quality. I received the email copied below today and, unless I have got hold of the wrong end of the stick, the company seems to produce virtually every make and type of bearing known to man. Is this eviden...

At a handsome 6ft 4inch I have just ordered the longer cables so I can fit my hi bars However I have a secret hidden hope, my clutch biting point is right at the very end of the lever. No matter how much free play I take out the biting point is as soon as the cable is pulled after the slack is taken up Reckon new...

Here's a pic of my last oil filter. It has bits in it, which I suppose means it did the job but I'll admit to being a bit horrified. Most are black but a few are metallic. I can't draw them out with a magnet so I guess they're either squeezed in really tight or non ferric. Anyone seen the like or have any ideas as...

I have acquired and trimmed up a pair of 2004 Yamaha WR250 foot pegs that now fit my 2004 TTR. The standard springs I have don't fit the WR foot pegs as they fit inside the stock peg and the new peg requires a spring that will fit around the lower part of the peg. Has anyone done this mod? Or does anyone have any...

I chopped up a scrap frame today and was surprised to find the upper subframe rails were blocked earth and fine grit for about 4" from the main engine cradle - see pic below.

Found a 2002 YZ 426 front end, wheel, brake, and shock for 180 bucks on craigslist. The install took three trips to town to get the right parts.

Popped out for a ride today and noticed that when accelerating hard in all gears from 3rd on, once I get above a certain number of revs the bike starts to rev like the clutch is being pulled in and the bike stops pulling. Driving at a more reserved pace isn't a problem, it only happens when the revs hit a cer...

Just a quick post to say that I bought one of these a month or so ago but have only just used it for the first time on TTR exhaust studs. It works really well and has certainly earned its place in my toolbox I used to use two nuts tightened against each other but that's such a faff - so easy with this extractor ...

On my "shopping" TTR, the choke makes the engine rev quite high which isn't what you need on a cold engine before the oil gets circulated I know it's going to do it so am ready but why is it happening The TTR runs perfectly otherwise. Brian

If have a Kuoba lowering link on mine and would like to put the stock link back on and give it a try. I noticed that the stock link the previous owner took off had the set off needle bearings in it.

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 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.........

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 )?

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...
