Hi All, Need a bit of advice. I need to get a new exhaust as mine is now far too rusty and i want a better one anyway. Which is the best front pipe/ expansion chamber out of DEP and Fresco Big One? I realise this is all subjective and down to personal experience etc but the Big one is around £60 cheaper. I already have a nice DEP back pipe. Thanks, Lee.

does any1 know what the best exhaust is for top end out of the following DEP Big One Gianelli Nikkon look at pics and info on .. http://www.dtr125.net/tuningpartsf.htm

i have a L reg dtr125 with a 02 reg engine and since yestaday it hasnt been starting and when it does it runs for about 10 seconds then cuts out, i got the AA out and they tryed the plug - superb spark, the fuel tap was letting fuel throught and there didnt seem to be a blockage from the tank to the carb but when spray carb cleaner into the air filter it runs ok, he said it will be the carb thats blocked and that need to take the carb off and clean it out but i wanted to know if it could be owt else before i take it apart cheers

i know these are very hard to find i couldnt find a second hand oneandhad 2 buy brand new which cost nearly £160 so hers a real bargain if anyone is lookingfor 1 http://cgi.ebay.co.uk/dt125r-servo-power-v...1QQcmdZViewItem

I have a DT125R '03 model. Showroom spec. Seriously considering the DEP pipe and can, which I understand means taking the main Jet up one size. Can anyone confidently describe how I would release more power from the servo assisted powervalve? I have viewed a lot of conflicting information on this very point and remain truly confused. Thx.

i am after the colour code for the blue dtr 2002 model i was told it was on a sticker under the seat but mine does not have 1 so if any1 can help plz cheers

.....exploring the mountain roads of northern Granada! Firstly the ascent to La Sagra...... You really don't want to get it wrong up here.... Parked up near the summit.... ....where you can see for miles! Then it was on to Santiago (about 40 miles) for a coffee....then back down the mountain. I decided to follow a forestry track....bloody Siracs are awful on this type of surface. Then turned off the track and went through the forest... Back onto the roads.....congested as usual..... There's dirtriding as far as the eye can see in every direction. B…

can it be done, is there the pysical room, would it be stable enough after before I go out and buy an engine

Well, to start out, I am not only new to this forum (this is my first post), I am new to owning a dirt bike. I bought my dirt bike from my cousin and it's in awesome condition - T-TR 125 One of the things that kind of creates a problem is that there is no muffler, so it is extremely loud. Since the muffler was ripped off, there is not a very clean cut, some of the metal is sharded out from the exhaust pipe. Anyways, my question is... what would be the best thing to do in this situation? Should i buy a muffler and try to wield it on myself, or maybe just go ahead and buy a whole new exhaust pipe with muffler? I'm going for a low cost - i actually have no ide…

I picked up a yz 250 and Im having trouble with the plug fouling. I ran it for about five miles today then it quit. I checked the spark and had none. Im mixing the gas 42-1. I just picked up the bike and Im just now going through it. Its been a few years since Ive had a bike. The last yz I was a 78' 400. Its a upgrade for me having a 91. Should i rebuild the carb? Is there an adjustment I can make to solve this problem? Marlin

i am trying to derestrict my 2001 TDR125, been reading the post lower about a 2004 dtr and the green and black wire and wondering if its the same system as my bike has the ypvs servo and is showing the same symptems of the power tailing off at 8000 rpm. the green and black wire on my bike comes from the back of the speedo and goes into the wiring harness can anyone tell me how to derestrict this bike if it is at all possible, i understand i might be following the wrong path with the green/black wire but it was worth a look cheers darren

Hello, I've just recently bought my first Yamaha.. Its a dt125 -86. I therefore just regged an account here =) Overall I am very pleased with the bike, I think it runs really well as I have only driven some old Mopeds earlier There are however a few small wonderings I have about the machine.. 1. The prev. owner claimed that the modelyear is 86 (wich is also said in the Registration papers) but the engine was exchanged to a -89! Is there someway to check if this is true? and are there big differences between 86 and 89 engines that may cause problems when I need spare parts? 2. I have driven a total of about 50km and the last time i drove it I notised that the Oi…
