Dt 125r 1997 tuning need help
-
New here but ive just baught a 1997 yamaha dt and cant find much about them online.
Already got full exhaust just wondering whats best to get for it. Im looking for alot of bottom end so i can get the front wheel up easily but not too much that i risk losing all the top end.
Also if anyone could point me in the direction of where to get parts for it would be appreciated.

Can't find much information? You're kidding right...
I dunno, sounds like to me you'd just benefit from the Athena 170 kit and be done with it.
I never recommend them because they're not great for tuning, but they give lots more torque, which will result in wheelies + no loss of speed.
Where as I prefer porting and tuning the 125 to give maximum power, at a sacrifice of torque.

@onewheelupuk try a smaller front sprocket my bike clutches up in 2nd and I’m new to it at at about 6k pull the clutch in rev limiter and pull should come up no problem make sure your pv isn’t pinned otherwise that will kill your torque there’s years and years of info on the forum so you shouldn’t be short on information

Well Iv got a 2003 dtr 125 and it does 85 mph even though it’s only got 80 on clock lol it’s never been rebored just standard size Athena racing piston in, full dep pipe, drilled air box and carb upjetted runs really well through all the gears acceleration is very responsive and sounds like a crosser due to airbox drilled best dtr Iv been on and had over the years. Where you from ????

@2003dtrdaz It's funny you say that cause the 2001-2004 DTR's were the worst. Absolute nightmare to derestrict, pretty sure you need to swap the CDIs out they're that bad.
Sounds like yours has been tuned slightly, but bone stock they're poo. Obviously same engine as all the others so it's nothing permanent.

In my eyes the older dtr are the best ones to get upto 2003 as they stopped making them in 03 after then they are all wank mate thts my opinion anyway who needs electric start old school better than new any day, by the way my bike standard as they come cdi etc lol

@dtrdaz03 The RE's are by far the easiest to derestrict. It's the fact that up to 1999, the last DTR's were severely restricted, and not even derestricting them fixed that. You had to swap out the CDIs. The RE's was just earth the green and black wire plus an aftermarket pipe and that was it. Again you're limited to the capabilities built into the CDI. Once you swap out the CDI for an aftermarket one then you are golden no matter what year your bike was.

the 2003 was easy to derestrict the standard 3rm-20 cdi I actually found very good. Restrictions were the standard exhaust and the reed switch in the back of the speedometer. They came with the powervalve from factory unlike some other years which I can't believe they did fit servos! Back when mine was 125cc it would destroy an 1990 DTR
