dellorto

I am having trouble getting the bike to start without choke and idle. It needs choke even when hot, starts and goes up to an enormous amount of revs. Turn off the choke and it will die. If I am quick on the throttle after closing the choke, I can run it with the throttle, but I have no idling at...

I have bought myself a non running 2002 Husaberg FS650 I want to get running. Since it has been sitting for approx. 6 years I thought that I would clean the carb as one of the things. (It has a spark when kicking) I have taken the carb out of the bike and it is a Dellorto PHM 40 ZS...

Hi! i just finished the engine rebuild, when i start the bike the engine runs fine with choke on, as soon i choke off it dies. I cleaned carefully the carb, the idle jet is 42, the main jet 190, the needle clip is set at the leanest setting, is this correct? This problem came out after...

Anyone have experience with 08 camshaft and dellorto carb jet sizes? Please let me know! Thank you!

My 94 600 is hard to start so I thought I should try and install a CD1 jet inside the pilot since my bike didn't have this. If you have the CD1 jet inside the pilot jet, how far in should it go? All the way until it seats? My bike is kickstart only.

The engine start easily.have idling.i give gas when the cracking the exhaust and drowning.the valve clearence is good ignition good but i need the carburator full description.thanks!

on the fs600 dellorto carb there is 2 upward pointing pipes.what connects to them?

If I lay my bike over /flip my bike and stall the engine, it is impossible to start. What I've found is fuel leaks into the inlet elbow prior to the carby, it does not need much to prevent starting. So I have to remove seat, air filter and soak up fuel with a rag then reassemble. It generally...

Is the bike still suppose to run if u fully turn in the fuel screw? It also only starts whitout choke and stalls if I pull the choke even a little, cold or warm no matter. Cheers, Tom

Hello again So I've blown out my carb now. The bike fires right up with the choke on, idles way too high, then mellows down. Feather the throttle, and she's dead. Turn off the choke and get the same result. Wandering what a good starting point is for stop screw and idle screw. Probably...

Picked up a tagged KSO FE 400 and it was puking gas like the float is stuck/leaking. The problem seems to be a worn needle valve (worn rubber tip) so I'm going to do a total rebuild replacing all the brass parts. The CD1 Type Idle emulsion tube was missing so that will be added and I'll drop the...

01 fe650. Does anyone have any suggestions on where to re locate the choke cable on my bike. BTW, I'll occasionally have a Clarke tank on it. Thanks

01 fe 650e Does the Dellorto need both fuel supplies on to run? I'm just wondering about leaving one off as a reserve. I can't answer the question myself as I don't have it sorted and running yet. Thx

Bike is a 650 with a dellorto carb. It runs good othertwise, but if you rev it, it stays on 3000rpm for a while, then drops to normal idle of 2000rpm. Jetting: some drilled main jet (just under 2mm), needle clip pos. 3, needle K51, DR272, pilot jet 40, and air screw 1.5 turns out. I tried to...

Hi there everyone, I've got a Dellorto PHMzs carb that I'm rebuilding and I need some help with what jets to start with for my area. Elevation: 1,500 ft Temp range: 75-90 Bike: 2001 470 with Lineaweaver X2(IIRC) cam and Big Gun slip on (it's the bike that the wonderful members of the UHE gave...

'03 fe400 with stock jetting running way too lean ! Have done all I can to stop the pinging ! With retarded timing a super spotless fuel system . An air filter loaded with filter oil . 110 octane racing fuel . Irridium spark plug . It still wants to ping slightly under load . All I can think of...

I just wanted to know am I missing out by not doing any of the delorto mods on my 501? For example the 4.5mm slide cutaway. The bike runs prime the way I have it set now and I hate to start over again.

I have a 97' FE501 with the PHM40 ZS carb that is running way too rich for my altitude (I live in Colorado at about 8500ft. above sea level). This is the second year I've had the bike and it ran OK when I first got it I had to turn the mixture screw all the way in, and back off the idle screw to...

whats best for a fe501e 2001 a dellorto 41 mm (standard) or a keihin fcr 39 mm (from a yamaha wr450 2005) should i change to the keihin or stick with the standard dellorto

Hi All, I`ve a FE400 with a Dellorto PHM 38 carb if i was to change to a 40 carb would it make any difference and what differnce would it make :?: :?: Cheers Bob.
