F*!k...you didnt even get the use from it after all you hard work...Gutted for you mike...keep an ear open for kids riding it locally? Hope you get her back fella

Moved to 'workshop' and edited title

nahh nothing to do with the rebore consider increasing the pilot jet on a warm idle...screw in the mixture screw slowly until it seats...if the motor doesnt begin to stumble ( too rich), then fit a bigger pilot jet because it should have done you fitted a new 140 main jet....was that in when the seizure happened?...what's standard in the DT175E? dont forget to raise the needle...if its bogged down with it raised put it back, if it's not bogged down leave it there it was too weak anyway in midrange Filter? a new one fitted...alll standard and oiled?

a bit vague that eden, post an intro and post your ybr ignition issue in workshp ...

bleeding releases pressure? yeah i suppose it does but there shouldnt be any pressure to release unless the brake lever is being squeezed...no too well up on hydraulic brakes though

neither did i...perhaps theres something wrong with the master cylinder?

Greetings chopperiyanto

:lol: happy birthday mike...honest i didnt see it mate. Good to hear you had a great day and give my best regards to her at no 63...cant believe she is still doing this after all this time

yeah yeah well done colin...how's the exhaust by the way?

yes it does of course, wanna buy a kph to mph converter i have a new one for sale...pm me if youre interested my import had a 240 and i fitted a 250 with a non standard carb and airbox

It's a classic sought after bike and deserves the time and money it takes to make it nice and keep it's originality, I'm not saying dont buy the different one as a temporary measure while the original is sorted though

I agree if it's only surface rust take it to a reputable place for re-coating...one that specialises in bike parts would be best IMO

Greetings Dan a nice bike you have found yourself there yep I recently had the same incident with a car coming from the opposite direction and doing a right turn in front of me...luckily i was able to stop as only going slow!

Greetings busta, well done on passing the DAS, yeah might as well wait til May now and save on the tax

in the short term try lifting the needle by one position and turn inwards the mixture screw by 1/2 turn, if it doesnt bog leave it there for now and make a note of the current pilot and main jet sizes, i assume the float height was checked prior to fitting?

Great little story, hunt out those pics Oohh a council run MX track!!

and how were we to know that? I find its usually best to start at the bottom...it's a new bike to you (thats why I asked), now if you had said..."suddenly my light dont work"....might have been a different answer

its happened to me Richard...it's a heat seize, too much heat...piston expands in the bore until theres nowhere to expand into! Carburation too lean......... fit bigger jets all round...pilot and main, in the first instance, try lifting the needle one slot if it doesnt make it bog all in all, more carb fiddling Another less likely cause is ignition firing too far advanced, ideally you set it using a DTI for 2 mm BTDC

Dohh yes that all seemed a bit rough arsed to me so i did mine in a more sypathetic way, like some YZ's were. see post #64 here

Greetings wolfspirit what does "qork this yoke" mean then

could be just heat seizing with the 'new' piston, really 30 miles and you're revving to 8k plus, is that recommended practice for this bike?

Greetings Reaper

Yup, thats what I got too

Yes assuming the little G7 has an AC powered headlight

dont rush into pulling things apart, it maybe that you just dont know how to switch them on! The fact the flash works may indicate bulb and earths are all ok Perhaps the ignition key has to be in another posision to arm the lights...who knows...study the bike / owner book etc
