my 2003 dtr has had all the usual restrictors took out and is fairly quick for a 125,but not quick enough.
just ordered my full dep system today £220 front and back pipe.the bloke said i wont get the most out of it till i fit bigger jets,could anyone tell me what size jets ill have to go up to?ive read through the forum and all the info is conflicting.some are saying 230-240 and -250???
that seems a lot from (as far as i can gather)210 standard.
is there any other thing i can do to make it any quicker or is that about it?
ive got the racing reeds/plug.and as far as i can see all the restrictors are out apart from cutting the rubber off the inlet manifold,but then some ppl say not to do this and others say do?
i know about the 170 kit but im not ready to spend £400 quid on that yet.
ive bought some book off ebay supposedly written by an ex yamaha technician(could be boloks but worth a try)saying theres a few other restrictions here and there that will release a few more bhp.
id like to hear some opinions on this lot...
thanks
