DT200R MACCA · BANNED

alright m8 have you removed any of the oil pump lines ? did you top the coolant up and do you know what size jet ur running?

Seiki · Admin

Also check for any air getting in, split hose or something

take the carb off and check what jets you have, you need about a 240, have you also checked your idle screw isnt all the way up so its idling high??

A faster idle can be caused by a lean pilot curcuit but there is other things it could be check all of the above. What mods have been done? What spark plug u running?air box mods? Did u remove the carb or inlets recently? Somthing is not right

1:Make sure ur tank filters not blocked aswel, yknow the little gauze things in the tank , gotta be fuel starvation or air leak, 2:get it started and spray wd40 or something flammable all around the intake tract and if it goes nuts you have found ur leak, 3:check the petrol cap is not blocked as this will cause less fuel to get throo,could be a creased fuel pipe also, 4: if all that fails take off the flywheel and check your woodruff key isn't on it's way out as timing can cause this also,hope this helps dude and don't give up it'll be worth it in the end

When you built te bike top end did you bleed the oil system?

stillbroke · Guru

hello everyone i am at my wits end the bottom gasket had a leak so did the top bodged them for now the bike is running at the moment and idles very well ON CHOKE! i keep pouring mounds and mounds of ****ing money into this **** with no pay back im going to have to sell it ! someone else can deal with it il swap for a 125 four stroke

stillbroke · Guru

i have no money left and cant afford to get another bike what can i do

stillbroke · Guru

ive put everything into this

Calum122 · Guru

You've got to make sure that there is no gasket left on the cylinder when you put fresh ones on. Otherwise it defeats the purpose.

PERSONALLY!

I'd INVEST £15 pounds into a new head gasket.

I WOULD NOT RUN THE BIKE ANY MORE!

If there is a problem with how it's built then you are just going to cause more damage and you won't be able to sell it for anything!!!!

In its current state it won't be worth much,.

WE ARE HERE TO HELP!

Get the cylinder off. Check its ok. Get some photos up.

Get a sheet of glass. Selotape some wet and dry to it. Water the wet and dry and gently rub the cylinder in a circular motion over the wet and dry to remove any gasket on the cylinder and to remove any imperfections.

Are you sure the head wasn't warped?

If it is do the same thing to the top of the barrel and the head. You'll need to take the studs out obviously.

You've got to be paitent.

If you buy a four stroke who's to say that won't go wrong. And they are a lot harder to work on than a two stroke.

DI d you torque the head and barrel downbwhen you reassembled or just as guessed? That was my initial fear so I went on scrounge for stag a torque wrench and feel little better kniwing they tightened to correct level

stillbroke · Guru

the prob is calum i just dont have the heart to do it anymore and i cant afford the garage ,and dread im very dyslexic (seriously) and i cant read a torque wrench ive got a brand new one but just cant read it .

eG x LoGiKzZ · Guru

post some pictures of the cylinder damage

Calum122 · Guru

To be fair mate Dyslexia has got nothing to do with reading a torque wrench. They are professional equipment designed for the profession. I don't know how to read one. I've just set it to what I think it should be and have had a go. I haven't had anyone show me yet.

It is disheartening mate but the fact of the matter still stands. With a non running dt regardless of its condition it WILL struggle to reach that high benchmark of £1200. It would be even worse to sell it for that much since if it were running it wold be worth more.

For that sort of money you could get a nice four stroke or you could end up with something worse than you've got here. That would be the real shame!

stillbroke · Guru

i dont wanna sell calum believe me and i know its high,i want to fix it but cant put my heart into it i need someone with more knowledge and patience to take the reigns on it as i keep ****ing it up the head must be warped and barrel ****ed to

stillbroke · Guru

the cylinder is on the bike at the minute im going to have a break from it as i know im just going to lose it and do something il regret

Calum122 · Guru

That's a sound thing to do.

Is it a necessary form of transport mate. I.e. you can't live without it.

If I were you I'd leave it sometime to get your head round it.

I wouldn't bother starting it again. If there's a problem with it then starting it up again is just going to exacerbate things.

stillbroke · Guru

yea i cant live without it m8 ,ive asked a friend to come up and help me fix it next week if theres two of us then it takes the load off of me a bit i took that top end on and off four times yesterday

eG x LoGiKzZ · Guru

im sure me or someone who lives near you could come down and give you a hand with the problem, you'll be disappointed with a 4 stroke haha

stillbroke · Guru

literally charlie matei just need someone to take the load off when youve done the top end 4 times it gets to the point where you cant do it again if i could get a few people down that would be great get a takeaway or sumthin and bosh it out ive got all the tools and haynes and a torque wrench im sure it will now need the cylinder doin il take it off at a later date and take some pics,im having nothing but bad luck this year and will be grateful if anyone can help i dont wanna go to the dark side (4t)

eG x LoGiKzZ · Guru

id be willing to come down and give you a hand (done it enough bloody times, i know the feeling lol), im sure ronnie, hayden, barney, matt and avi and ad will be up for coming to help too? need to go out for another ride out like we did before, was great fun!

stillbroke · Guru

thanks charlie ;) il get the funds for some parts (gaskets) i think though that the cylinder cud be ****ed the piston is scored but doesnt seem to be causing any issue how much would a new piston and rebore be ? ive had it done b4 but i think there is cheaper places

eG x LoGiKzZ · Guru

usually costs me about £100 for rebore, piston kit and small end bearing, head gasket is about £13, put some pictures up from up the exhaust port so everyone can look at the damage, should be able to tell what caused it exactly

stillbroke · Guru

its an air leak mate the damage was caused as when the air leaks it makes it run lean so it heat seizes

eG x LoGiKzZ · Guru

have you ever upjetted it? that night we went out my bike was running lean (and for the next 700 miles!) after i rebuilt it, put a 240 jet in from 210 and its running sweet now

when we went out i did think your bike idled funny like it had an air leak or something

stillbroke · Guru

its running 240 and ive never got it to idle for long without the choke .always have to rev it

dread123 · Moderator

Rebore and piston approx 60 at Grampian motors vin liverpool. Google them.

eG x LoGiKzZ · Guru

stillbroke · Guru
