So I just replaced the piston rings and cam chain on one of my TTR's that had a little rattle in the (so I thought) top end. At the time there was little to no play in the big end so was left as it was. Few rides later and the noise that never left was back and at the first oil change the (after 2 hours ridding) the...

How do people clean their spokes? Want to know as it is the part of ttr I don't know how to clean. And keeping it clean seems to be the main part of maitenence because it is a trouble free bike!

Seem to have developed a starting problem on the ttr, where I put the choke and fuel on crank the engine, it starts straight away but the dies. I can do this 4/5 times and eventually I can get it to keep going but before this it used to start on the button. When its warm/hot there,s no problem I can start it eas...

Hi I have just bought a DID gold O ring chain for£10 on ebay, but has no soft link. I have never used a soft link and would I need special tools. Can I use a split link with O rings? cheers Dom -- Edited by rdchair on Thursday 21st of December 2017 09:41:26 AM

As the subject suggests, I replaced the chain & sprockets, nice gold DID 520 chain with 13T & 44T sprockets, am I the only one that loves the feel of new chain & sprockets ? 16500 kms on the OEM units, not bad for a dirt bike & I could have reused the rear sprocket. Spending more time on the W...

I picked up a rebored barrel for Steve this morning (first oversize so no double boring charge as was the case with the 280 kit I had done back along) and the price had jumped over an 18 month period from £46 to £54.

Hello knowledgeable peeps I have just discovered the base gasket under the barrel is leaking oil - only very slight but sadly it is none the less.

Gday guys, Forgive me for my lack of mechanical apptitude. I have a leaking head gasket, very small and slow leak. I am going to take my bike to the mechanics to get that repaired, my bike runs sweet and has 6500 kilometres. Would it be worth getting a new piston and ring done when the head is off?

Hi all, First off, a quick introduction. I’m Ollie, and I’ve had my TTR for a while now (a year or 18 months, can’t remember exactly). It’s a K reg metal tank version. I use it for green laning so it gets a bit battered and bruised, but I always give it a lot of TLC after each trip! There’s one slightly odd f...
