DERESTRICTING GUIDE
-
Hi All -
Just thought I start a thread with a guide on 'how to' derestrict your DTR/X. Here's a very good guide to start with, you may find it easier swapping the full exhaust with a DEP, Giannelli or similar instead of cuting up the front pipe. If you have any other tips or links then please chime in.

The RE/X has got to be by far the easiest to derestrict.
Earth Green/Black Wire, new pipe. It's like Yamaha new we were going to get full power haha!
They were also packed with only 3MB heads and all the boost bottles.
Probably still the slowest nevertheless lol.

Available from Fowlers.
Yamaha DT230 Lanza Airbox duct. Really nice upgrade, much larger duct for more air intake. Jet slightly richer towards 3/4 Full throttle and this Duct will work very well.
A little material has to come away to seat it's larger flange, so be sure, and commit to jetting if needed.
Better sound there too.

The later Airboot YIES bottle was introduced for better low RPM induction and emissions. It works really well for the Midrange, but makes the bike a little flat on top.For Top end, I use the older Airboot without YIES. It works better for higher RPM.

What does the black/green wire do?

@irongamer727 it removes the restricted rev limiter on the bike
