Airhead

Dom isnt there a nut of some sort to tighten it all up? a pic would have helped

Greetings Oscar I'm so glad my bike isnt as old as me either or it would look like this

Crikey thats gonna fly when you get her going, looking forward to seeing your progress and a few pics, why not start your own thread out of this intro's area? Greetings and ...Paul

And its a stroker 70's trailie, look forward to following it, seeing it finished and having a spin around squires one day

Its a marketing ploy to try to convince friends of the earth and the like that 2T's are a good thing.

Hows the TS coming along DDT?

You should have airbox connected and filter insitu, choke ON and little or no throttle opening, set the mixture about 1 1/2 turns out at a guess...at least the plug should show signs of wetness even if it didnt start I think it's a fuel related issue Where is the reed inlet attached, barrel or direct to case?

What about the choke, I dont know the bike or the carb but it wont start without a choke ? Edit you put your hand over intake of carb so is the airbox disconnected?, this may also upset matters greatly

Great pic John, baby looks to have a huuge smile...

Greetings Des I used to drool over a 250 Desmo cafe when I was at college, one of the student bought it...twas a beautiful looking and sounding machine....coincidentally, another student had a YASI I see merv gave you a pionter, I would also bookmark govnors bridge and Jim Patch http://shop.ebay.co.uk/bloke0/m.html?_nkw=yas&_sacat=0&_odkw=&_osacat=0&_trksid=p3911.c0.m270.l1313 http://shop.ebay.co.uk/hamhill3/m.html?_nkw=&_armrs=1&_from=&_ipg=25 ,,,Paul

A power valve, if it has one it will need a good battery to operate it,

Yam filter may have been OK but as you say the jet is bigger than it should be...something to consider?

Have you tried a new plug Kyle and does this bike have a PV?

mine

no it doesnt matter, whichever way fits best

Did you not read what I said James?...they attach to the small coolant pipes from the cyliner head

it'll do for now so You will see that the carb has two connections for the small coolant pipes from the cylinder head, and of course a connection for the fuel supply ...Paul

I would be cautious with the DT100, I have seen ballast resistors and avalanche diodes fitted to these machines

an intro James? (New members) if you can spare the time that is

Despite my silly username I bet youre older than me we hear this now and again Mike, better late than never...take care and a great choice of ride. ...Paul

carb float / needle valve may have jammed, try giving the carb a tap with the wooden shank of a hammer...sometimes it frees it. Otherwise you will have to investigate further.

maybe /maybe not You may have blocked the venting hole on the filler cap with vaseline? When it starts acting up pull over, undo the filler cap and re fasten it then ride again...see if its better...If it is you need to discover how it vents and clear the blockage.

I'm not so sure it's the carb at fault here, the fact that it is ok sometimes and not others, if the carb were gunked up it would always be bad. by the way dont use gasket sealant on carbs, it's risky and completely unnnecessary. I have heard though that theres a filter gauze somewhere, possibly in the spigot that the fuel pipe attaches to...ask '2wheels' he mentioned it recently. is your PV operating ok? does it undego the cleaning cycle properly when you switch the key to ON?

Simon smokey when cold is normal. Your bike likes to take you to work but not bring you home...was it a gift from the boss

Always keep the chain lubed, I use yoshimoto kingood chainspray, its oily rather than waxy like some. Oh and a RAC card for recovery if you puncture.
