YAMAHA21

I understand about it being over my bhp limit but when I flick the switch it's under so does the fact that the wiring is slightly different make it illegal? I'm pretty sure I'm limited to 15bhp. http://postimg.org/image/yk3zqgqxx/

That's quite worrying, the amount of learners that have illegal dt's but probably don't even know it because they don't know the bike is derestricted. Also, how does the mod invalidate my license?

I'm thinking about installing a rocker switch where you can switch between restricted and derestricted modes. Where does that leave me with insurance, If I had an accident but just switched it to restricted mode, there is no proof that the bike was derestricted at the time of the accident.

I want the bike to be legal, but it's so much easier with it de-restricted. The thing is, what's to stop you just pulling the wire from the frame if you had an accident, as soon as that wire looses contact with the frame, it's restricted again.

I was under the impression that everyone does this to their dt125's. It must be quite popular if the 2 that I have had were both derestricted when I got them.

Any idea what the hp has changed too then, is it a big increase or a small increase?

I appreciate it, Cheers

Would the authorities be able to tell though, how would I get done for it?

I went to go for a ride today and I noticed that where I had re-earthed it to the frame, the bolt had snapped. After fannying about a getting the broken bit of thread out of the frame, I tightened the bolt over the wire again and went for a ride to see if it made a difference. It felt light a different bike, It had much better acceleration, I actually manage to travel some distance before having to change up to 2nd gear and the bike was much more comfortable going at speed where before it would have been buzzing and vibrating like anything. So where the person earthed it in the first place was crap and where I earthed it after that, the bolt broke. But it's great now, I only went for a little ride but it reached 9k rpm

Before I had my 2007 dt125x, I had a 2000 dt125r and I remember that it used to love to rev and that it redlined at 10.5k and went to 12k. I have recently fitted a tachometer to my dt125x as it doesn't come with one and I noticed that when I'm riding, it doesn't want to rev past 8000rpm. I know the tacho is accurate because it reads 1.5k when idling. When I reach 8000rpm, the bike is screaming. It was derestricted behind the speedo when I got it but I earthed the green/black cable to a different place on the frame to make sure, it made no difference. I'm assuming that the x and re models redline at 10.5 as well. Also, the bike runs fine, it pulls pretty well up to 50mph but after that it's gutless. It takes ages to reach 70 and the most I've got from it was 72 off the speedo. I've seen some people say they get nearly 90. So is the bike still restricted somehow or do the newer model dt's only rev to 8k. Also I forgot to mention that the bike has a full dep system. Cheers
