Air delivery or electrical delivery? Air filter clear,clean...coil/cdi steady? Just a thought...what part of the throttle do you mean under load? 1/4, 1/2,full/wot? That might help identify which circuit for fuel delivery?...How old is old?

its an 85 model air filter is clean spark seems good

it seems fine at higher revs just flat lower revs (no rev counter)

had another tinker and can get it to start within first couple of kicks but still dying when the throttle is opened quick if you very slowly open the throttle it picks up this happens in neutral as well as when its in gear im sure its fuel related but im missing something some where

Not an expert but seems like that was what was wrong with my older bike...after sitting, It would idle, but an quick blip on the throttle and it would cut out...floats ok? correct level? Sounds like fuel delivery after pilot circuit in carb...someone already mention petcock functioning with enough flow for more than idle?

I'd guess its carb related, check the pilot & main jets for blockages, make sure the float is at the right height too, then check the pilot/air screw. Have you got a service manual, when I had my DR600 I managed to get a genuine manual from ebay for about £20, it took 6 months for me to find one, but they turn up from time to time.

Once you get it running properly, your next problem will be stopping it, they've got the most feeble front brake ever fitted to a motorcycle! I've got a spare late DR650 front end that will give you better forks and a useable front brake if you're interested...

main and pilot are clear float seems right cuts fuel off just before it overflows as for the air screw played a little but put it back where it was. got a service manual in german that with the help of babel fish I am slowly translating

as for the front end that can wait till its running right

ITS ALIVE

ripped it all apart again stripped carb incase I missed something, took all the jets out again to clean them full can of carb cleaner through every orrifice. checked the pumper part was all free and facing the right way all looking good so far.

so not to rule out the electrics I disconected every plug I could see and sprayed wd40 in them making sure they weren't green. this is when I noticed some fresh looking electrical tape, unwraped it there were 2 wires that were just wraped together followed them both back to the coil! soldered these up taped them up nice and neat and put it back together.

kicked it over a few times and it fired up quick squirt down the road front wheel up all good.

thanx for all your help

Another happy ending.:smirk:

Considering how ancient they are, they're great fun once they're going!

great old bikes, i was out with a friend last weekend and amazed how fast he got around on his old dr600, shot some footage of him and posted it

. does anyone know if this was lighter and more powerful than the DR650SE that came later?
