Hi All have had my reeds fracture so brought the only reeds the local shop had. these are boydon raceing reeds,(looks like they have had these sitting around for a while) does anyone know how much these change the engine with regard to the oil delivery system. ( i take it with the more petrol going in the more oil it will need) the carb has already been up jetted in the past + filter , dont want it for speed , just to keep her running for work ( engine ty50mx 1980 fitted in dt50mx frame and running gear). cheers nigel

never gave it a thought about filter and wasent aware of jet size , will know next time, will be a bit more methodical taking things apart next time. cheers

Hi.turned washer other way up and needle seems more secure, choke now works, still looseing power so disconected filter at carb, re connected and tried withpout filter still going strong put filter back in and problem came back, yam filter was brand new of the bay , purchased a ram filter and cut to size fitted and bingo were back in buisness, must have been conbination of duff filter and carb notput back together properly. many thanks for you advice. cheers nigel

in the gel battery world diffrent manufacturers of the same size battery are always slightly diffrent in capacity, we use a lot of them at work and come accross this a lot, battery will be fine .

Hi, Will turn washer over tommorow and give it a go. Cant find this particular type of washer in the manual? Anyway thanks, will post result!

hi the washer in the to is over the needle but the washer is a y shape , all three sides are angles down and the spring sits on top . the needle has some room to move . the clip is on the bottom setting on the needle ( only 2 settings)the jet size in the hanes manual said 88 but use to run on these settings about 2 years ago before it got stripped for restoration ( seemed like a good idea at the time )maybe time for another carby

Hi . i have a gel battery in my DT , original battery was 6v 4amp the gel on is 6 3.8amp . the dimentions are diffrent so had to mount on side ( data sheet with battery said mountable anyway.) it seem to charge ok had to change terminals on power cables , at least i haven't got to top up fluid every few months.( got from electrical wholesalers)

hi had carb apart, all parts present. needle jet has 059 on it, main jet 105RD (book said 88) needle jet has 80 on it (i have no refrence to this in manual).float level correct , pilot jet unable to read clearly but think it looks like 40. teikei carb think its a Y14p. bike still starts without choke from cold and stalls when it put on. tried to adjust pilot air screw . screw in till faulters then when screwed out i ended up unscrewing completely ( end of thread)and it still runs. any ideas ? air filter is stock and new ,checked connecting hose for holes secured jubillee clips, when riding it starts to hold back , if youkeep bliping the throttle it picks up power and goes , if you keep it in the higher reves it goes good.

Hi think main jet is there and tight but will check again a check size, i did notice that the needle does move about a lot left to right and also a little bit up and down. it seems to be held in by a washer sort of thing and inturn this is held down by the return spring, will check over weekend thanks and will let you know the outcome.many thanks

Hi it starts without choke, if i turn choke on it dies, have had all tyhe carb and jets out cleaned and blown out with compressed air, still scratching my head. going to have a look at the electrics at the weekend, would a bad earth couse this problem ?

Hi All i hae a 1985 DT50MX CDI with a 1980 TY50 engine in, when you pull away all is fine then about half throttle is holds back for a while then goes well again, as long as you keep the revs up its ok. (like getting starved of air/petrol) i have cleaned carb out cleaned jets and blown out all holes, have new air filter and spark plug and coil fitted( secondery high resistance 6Mohm) ( was playing up before i fitted these). it kicks over first time, have checked for air leaks but cant find any, has had an engine rebuild about 1000 miles ago , all was working fine a year ago ( has been in shed since then , just been getting it ready but cant put my finger on the problem any ideas from the experts.

Hi All will try and get some pick on she's nearly up and running.
