Thanks m8 its correct then

Gents my rubber compound boot that fits in with the reed vales. The thing that directs the fuel down into the reed vales only has one prong to it. Is this correct or should it have two prongs

Purchased one today m8, should get it by monday

Gents took the reeds out and they look new. Had a look a the spark plug and it looks like this

Hi gents, Have just had new bearings and seals in the crank. Carb is all standard. (Correct float hight?) Engine is running much better but apears to struggle to idle.

Its had new bearing and seals but will re check. cant look until tomos

Well i can only look for air leaks. Not sure what else it can be. I take it ylu judt let the needle slide cut away bit hit the bottom and then ajust throttle bable to suit. Then idle screw?

Mines the first version m8 Mikuni VM24SS, Number 2H500 Standard Set up with factory porting, standard exhaust and air filter Throttle Slide cutaway, 2.0 Needle, 4j13 Clip position 3 from top Needle Jet, 249 0-2 Main Jet, 130 Pilot Jet, 25 Reed side diameter, 35mm Filter side diameter, 43mm Length, 85mm Float Height, 21mm

160 main jet, its a 130 standard on the 175 ) Thats the carb now fitted m8. with new internals

Its a 1978 but will check if its points and reed valves tomos.

Hi all, DT feels like its missing between 3 to 5 thou and isnt crisp at all, very spluttery. Engine is very quiet with no knocks or rattles what so ever. It will still pull to 65 but it dont like it. will clean carb but whats standard settings Also have the same problem with this bike as 175. Cant get driving lights to work? All other light function. obviously i have the bike running and have checked fuse but now joy:o(

DT175mx runs much better now ), very crisp but i am struggling to get it to idle? air screw set 1 1/2 to 1 3/4. It either dies or its above 2000rpm. adjusting the idle screw Still need advice on the 250mx. Feels like its missing heavily around 3 to 5 thous. Not very crisp either. bit sluggish. Any advice would be great.

cheers oldgit, ;o). Doing what you said. Have taken a loan out now so may keep it. But also managed to pick up a dt250 so will have something to mess with. Can you tell me standard settings for the carb dt250 mx 1978. Runs ok but feels like its missing around 3000 to 4500 revs. Hit it all the bloody time.

I can blow through it but you dont get a massive blow through. Have put some tiolet cleaner in it and will power wash it through in the morning. Will also put original carb back on tomos.

hey you may be right, perhaps thats why he changed the exaust. will have a look in the morning )

Ok gent, Just had new crank bearings and seals. Starts well then starts to splutter very soon and does not rev. Only %83 compression so will that cause this ? what else can it be? at my wits end here. Looks like i will have to get a loan to pay solicitors at this rate;o(

Ok gents, engine has had new crank bearing and seals but still runs poo. I can kick it over with my hand so going to try new piston and rebore. Had new rings but dont think thats enough. Hopefully this will sort it. Will probably still have to sell but hey lifes a beach. (

no not genuine. reproduced m8. Think its just the stting up of the bike if im honest and i dont have a clue regarding that. If it aint that it has to be crank seals? Paid once to get it sorted in the shop but they were crap so not paying them anymore. but will pay to get sorted by someone who knows what thee doing.

The carb is totally new so all standard. Stressed at mo Bloody divoce crap!!

Anyone local to me who knows what there doing and can sort this for me and earn a few quid?

Still not runing right, new carb fitted all standard. It starts but smokes alot and stinks of fuel. Havent managed to get it ticking over yeat. Just seams gutless when you rev it. Spluttery not crisp.

Fitted new carb but it still apears to be the same. Loads of white smoke and strong smell of fuel. Still not managed to get it ticking over.

I was thinking around £1200 to 1300 but hey i want to keep it ;o)

The engine jus had new piston and rings and repainted the side casings. Stripped the bike to bare frame due to being hand painted. Plastic coated frame and put new bushed etc in swing arm. Had to respray tank due to bubbling and side panels to match. Rebuilt forks. New handle bars,indicators,battery and cables. Now will have new barb. wheels rebuilt a few years ago with new spokes. A small amount of crome flaking on rims but not much. In all not perfect but im happy with it. If i sell what do you think i would get? Only had 3 owners with a lot of history.
