I have got a 2004 DT-Re 125 and the Y.P.V.S Cable snapped so I ordered one from Yamaha and when I got it back it was totaly different. Is there any chance some one could hav fitted a different Y.P.V.S to my bike as the dealer checked my frame number and was positive it was the right cable. I will post some pictures if I can.

I have recently bought a new Barrel From Ebay (As mine is Fooked) Does anyone know how big I could Bore it out and how much a piston and Re-Bore would be???

Hey mateys, been offered a "DT125" - dunno anything about it, except that it's in pieces and its had the frame repainted as it was a field bike... it'll be a mid 80s bike i would think It's a mate's dad who's got it, this guy does do good work, it'll be as described.. I'm going to see it in a few days and i'll make an assesment on how far gone it is then, but i know nothing about 2 strokes, never worked on one.. in fact it'll be the first bike i've worked on other than servicing the honduh - done plenty on cars though. Just wanted to get the thoughts of yam experts.. are they difficult to work on, DT125s? anything i need to look out for? it'll be SUPER CHEAP like…

Hi, I have a 1993 XTZ660 Tenere and it was running very nicely. Recently it has developed an annoying habit of cutting out on idle when warmed up. Its fine for about the first 5 miles then whenever you stop after that, the revs drop to zero, she cuts out and is a b***h to restart until she's cooled down a little. I've had the fuel tank cap, the valve clearances, spark plug gap, idle and mixture settings all checked and its still happening. Could this be some kind of electrical coil problem? I am no mechanic so please help if you can. Many thanks.

Hello, I need some advice about how to check possible mechanical failures in a 2000 XT 600 E. I don't now anything about his owner, he lives far away from my home so I can't have a professional mechanic advice in the owners small town and see the bike. Here in Argentina the 2000 model in advance is rare to find, but I know that it's easy to ask for any kind of spare parts... takes at least five weeks to get them. I'm going to watch the 2010 Dakar edition at Copiapó, North of Chile. The round trip will be more than 4.000 miles. Thank you very much and kind regards from Southamerica.

Hi, earlier this year while enjoying the couple of days of summer we had i decided it was time to stop talking about it and finally go out and get my cbt done. So with that out the way i went straight out and got myself a '05 Yamaha Dt125R SM and have loved every minute of owning it. However with winter now coming up fast i'm not sure i want to just put it away and leave it sitting there for months, so instead have been playing with the idea of fitting some knobblies to her. Only thing i'm not sure about though is what i can fit. Will i be able to just go out and buy a secondhand set of DT125 RE wheels off e-bay and bolt them straight in or is there a difference in anythi…

I was wondering, I have a 1980 175 dt as you know by now. I have a 1.75 x 21 inch tire on the front of my bike. Can I put a 3.00 x 21 on it? I have a chance to get a brand new one for $20. my 1.75 is partially dry rotted.
