[dtr125 jetting]

yes is a 240 jet in there,just confused how the dep system needed no adjustments and the bike ran fine with it on and the big one system has really messed with the bikes performance,5th gear is a stuggle to use and 6th is totally useless no power at all as the bike sits between 7-8000 rpm in these two gears,its a real struggle to get 60mph at all

[dtr125 jetting]

i have just fitted a big one full system to my bike it is fully deristricted but bike now has a nasty flat spot in top gear inbetween 7-8,000 rpm,does any one know which jets to change and what sizes,bike had previously had a dep system that went rotten and could not afford to replace it and had no issues with this pipe,the bike is a 02 125 by the way

[Dtr Speedo restriction]

i have recently bought an 03 Dtr only to find it was still restricted when i got it home, what a bummer

im part way through doing the derestrictions to it but im having trouble with the simplest one, the reed in the back of the speedo.

ive taken it out the back of the speedo and put it put it into a plastic bag with plenty of tape for good measure but the bike is still limited to 60mph.

was wondering if anyone else has had the same problem and if anyone can tell me what im doing wrong, any help at all would be greatly appreciated.

cheers

i had the same problem with mine untill i fitted a full dep exhaust system the airbox mods and a set of carbon fibre reeds
