Hi all, looking for some advice or maybe a reality check I’m not sure! I’ got my raid up and running last year and have starting using the bike for green laning. most of the time this requires riding for 30-60mins to meet up with others and get to the dirty stuff. The bike is fantastic and more competent tha...

Hey everyone! I have a TTR250 Raid from 1996 which i bought about a year ago. The last couple of months, after some changes i made, i have noticed that the motorcycle behaves a bit odd. It feels like it hits unusually high revs at 1/4 of throttle and when i open it 1/2 or more the engine feels like working rea...

Hi All, I'm looking for some spares. They are not available through TotallyTTRs, Wmoto, Fowlers. Is there another outlet Im not aware of? If anyone is breaking a TTr250, then please get in touch if you have engine parts for sale. Cheers!!

I have noticed on my TTR250 2007, when main tank is near empty, before switching to reserve, the throttle seems to stay on, like it is sticking. It has happened twice now at the same time (just before main tank is empty. This is the first Carby motorcycle I have had in years so maybe this is normal. Can anyo...

Well I'm back. My faithful old TTR was stolen 3 years ago. I truly didn't expect to see it again, thinking it had been parted out and sold or similar. However about 2 months ago I got a call from the Police saying they had located it. Apparently some local scumbag was caught riding it. It had been thinly dis...

I just had a new top end put in my bike - not sure yet if this is related or not. When I get on the throttle about 1/4 or 1/2 throttle and hold the throttle in position, the engine oscillates up and down, up and down.... The bike starts and idles perfectly. I've take the carb apart 3 times and cleaned the jets a...

Can someone please tell me the length of the speedo cable. Bought one from Fleabay that advertised as being for my model TTR250 but its too short, just barely reaches directly from the hub to speedo. Certainly won't go through the cable holders.

Hey all, I can't seem to dial in the free play and reach of my front brake lever. Even with the reach adjustment dialled in as close to the bars as possible the lever still sits far out.

Hi all, Just wondering if anyone else has experienced this. When I have not started by TTR for a few month. when I come to start it it turns over easily but doesn’t show any hint of wanting to start. I then try it on the kick start and there is very little resistance. after 20 or 30 kicks resistance builds up...

I changed out front sprocket and chain today. I know it's standard procedure to change rear sprocket also, but it showed little wear at all.

Good morning bois. My son bought and rebuilt a 2004 TTR250. It ran rough and wouldn't shift. He split the case. Put in a transmission. Honed the cylinder, new piston, new rings, new valves lapped in and leak tested. He couldn't get it to start. It's got spark. He claims he cleaned the carb out. Timing sho...

Hi guys i have a 2001 Yamaha ttr250 and when we got it we noticed that when you rev it the revs don't go back to idle they stay at the revs you were on and the only way you can get it back down is if you quickly rev the throttle. We have cleaned the carb checked the throttle cables and checked the choke but nothing...

Hi all, I was out a couple of weekends ago on the TTR for the Borders Rally - first rally and a fantastic weekend... until the bike lost all drive!

Brick cleaning acid works wonders on dirty exhaust headers but an alternative that I have recently found is to use a wire wheel on a bench grinder.

I need to replace the filters on the ends of the petc0ck, on the brass lines that are inside the fuel tank.

Hi Guys, My 2005 TTR250 has a high pitched noise that gets louder with RPMs and when the engine gets hot. Clutch in or out makes no difference and neither does bike speed.

Can anyone recommend a good fastners set that is availabe in the UK?
