January 13, 201510 yr Bit the bullet and ordered my boost bottle and reed block with hose. Arriving 28 jan. Woohoo!
January 17, 201510 yr Aye simon, read first post,, big jump in performance, . Airheads a lazy fker nowadays ,,he aint fitted his,, hes a 4stroker now
January 18, 201510 yr Will let you know. Might have to use cable ties until I get someone to weld the tags to frame. looking forward to result! S.
January 18, 201510 yr the boost bottle makes a small difference, the biggest difference from the original poster is the swap to carbon reeds, they give it a way better bottm end
January 22, 201510 yr Moderator Hope it doesn't disappoint. But that boost bottle stuff was to improve bottom end torque. If you want power from a 175 you need the later airbox and a good pipe. Still be flat out at 55.
January 22, 201510 yr Moderator Nah only 1 think kills dt175's no way round it and kills them as sure as giving one to grouch. Revs. They dont like it over 8k cos the piston overheats and either nips the rings or holes.
January 23, 201510 yr Looks like its jinxed. Being held at post office buyer being informed of charges. S.

January 28, 201510 yr Well picked it up from post office. Still smells of petrol. Complete with reed block bolts still got the zinc plating on them. Does nothing corrode in America? S.
June 9, 20159 yr hi all wish to tell you of my experience of trying this mod to my dt and hopefully answer some peoples questions as you can see it is very heavily modded bike ,you name it and i,ve done it or tried it with this bike and other dt,s ,anyways the fitment of the boost bottle was fairly straight forward,just using cable ties to secure it at the moment and had to put another jubilee clip on so it would not touch the cylinder ,don't ask about the throttle cable ,it still works but might cause others a few issues ,i would also like to add at this point i have tried various inlet rubbers from other yams dt125lc rd 350ypvs and they wont fit with out serious and pointless modding ,the one off a Yamaha Rx 100 125 135 will fit but your have trouble with the exhaust being in the way and throttle cable ok so what has the boost bottle done to performance and is it worth doing, right first of ,big yes, especially if you have ever done any modding like changing the exhaust front pipe ,porting ,at the moment i have a rd350ypvs carb with a separate mikuni power jet fitted with the original needle from my dt 175mx so i can try and get the bottom end jetting right ,the bike would gas and fart at low rpms and when you whacked on the throttle it was to rich , when i fitted the boost bottle it was a massive improvement to my low and mid range riding , it felt a bit lean at first in the mid range, so i made it richer on the needle which was a big no no before and runs even better now, when you ride it fast and let the throttle off there's no more coughing and spluttering ,it feels really neutral,like the engines turned off or some ones put there hand over the end of carb ,and when you whack the throttle on ,it picks up straight away , i would say if your have issues with you low and mid-range and can for the love of money get you needle right then this is well worth a try ,i would also like to add ,a couple of months ago before i fitted the boost bottle i changed my older style fiber reed petals to the newer carbon fiber ones ,there great,my bike before all ways ran like it had an air leak until i changed to carbon fiber ones
June 10, 20159 yr Looks superb . . What does that boost bottle actually do ? And how does the clutch stand up, this where the next upgrade Is usually
June 11, 20159 yr the boost bottle improves the bottom end and as for the clutch, it is what it is, slips when its cold fine when it hot ,its all ways been like that even with better clutch springs fitted ,
June 11, 20159 yr Moderator Did you not find those forks really limited the bike. I fitted a set then went back to the originals. The loss of turning circle and the twitchy ride off road was not worth it.
June 11, 20159 yr I would suggest that the original forks be put in the skip still attached the bike ,,no only joking ,the dt 125r forks are way better than the standard ones ,the dampening is way better and the best part of changing the forks is the front disc brake, you can stop now which is what I wanted to achieve, I will admit to loss of steering lock but only really need that for parking ,I did find that changing the rear tyre too a fatter one has made it a bit unnerving at times.
