Got a knock yesterday and the left hand plastic lug that comes back and bolts to the headstock now has a length of around 2-3 cm missing in the middle. If I can get some plastic sheet it looks like I could glue this to the remains of the lug at the surround end. Anyone had any experience of repairing the plas...

Own a 2007 TTR250 Aust build. Managed to smash the headlight lens the other day. Doesn't look like there is anything much on Ebay in relation to the OEM lens as a replacement. Can I still get them anywhere? If not will anything else fit? And for your entertainment.... [video=https://youtu.be/ya9Hd...

Hi there, Doesn't seem to be a thread on this at the moment. Can anyone recommend a good instant gasket for use between the crankcases? I have generic gasket I have used on other parts of the engine well however I want to make sure this is as robust as possible to avoid future issues and a huge waste of tim...

Ok, this thing is not responding to my advances. Bike was left sitting for over a year, carby was the first focus of attention, needed ultrasonic cleaned etc and new diaphragm for the acc.

Hi there, I split my crankcases today and noticed a crack, I dknt think there is any issue really but I'm not 100% sure. Can I have your opinions please? I guess worst case I could get it tig welded or something?

Hi, I’m hoping for a bit of advice ?? I’ve got a fairly low mileage 2004 TTR and until yesterday the starter motor has been faultless....and the yesterday, part way through a long day, it suddenly ‘spun‘ but didn’t engage, if that makes sense ?? I could hear the starter spinning but it’s not turning the e...

Anyone have any experience repairing a cracked tank? From what I can see, plastic welding would be the way to go, but it's important to exactly match the plastic compound to the tank to make it a long term solution. I've been trying to find a tank for my '99 but they're nowhere to be found.

Just bought a 2003, my first bike. I had no clue what to look for when checking it over. I took it out for an hour and dropped it at low speed a few times. Shut it off quickly, but it left some oil on the ground each time. Looking around, I saw a at the top of the cylinder head is a valve with a hose right next to it th...

I fitted a new clutch to my TTR and replaced the Gunk that a previous owner has used with a proper Gasket. At the end of a long Distance Trial I discovered that the bike had dumped most of its oil. During remedial surgery I noticed that on both the clutch casing and the engine casing there is evidence of a ver...

My bike wasn't started for a while now, I did a carb cleanup and replaced the fuelling issue, but now it feels like it doesn't suck air in but the exhaust side works, can this be a valve being stuck? Or a timing chain issue? I don't want to open the engine, it's hard to find the gaskets here

Hi all, I'm looking for clarification please. I've read in a few posts in here that the top piston ring is the ring with the marking. As I see it the only ring that will have a certain orientation, and thus require marking, is the scraper ring - because it's important what way the taper faces.However the T...

Well, it's been a while everybody! I just wanted to let all you fellow TTR enthusiasts that all has been well except for a split intake stub.

Hi all, sorry if this has been asked many times before, but what is the usual distance you can travel before going onto reserve when off-roading. I appreciate a lot will depend on the terrain and so on, but would I be right in thinking about 100 miles or that is that asking a lot ? Thanks in advance for your c...

Hi all I'm hoping to get some insight from this group. My TTR started ticking right after an oil change. Idk if the oil is maybe too thin or maybe it's just a coincidence.

I have recently been bottoming out occasionally on the rear shock and believe the best way to reduce this is to increase the compression damping. As I understand it, this is normally very easy on a TTR, just requiring the hand rotation of an adjustment knob on the remote shock reservoir canister.......
