another bonnie rough running

[davidg]

bought a 66 t120 from a dealer who told me it  ran but hadnt been used since 96.changed oils cleaned out tank and carbs started 5th kick plenty of tickling,but only ran for 4-5 secs at fast throttle then died.cleaned out carbs this time spent a lot of time on pilot jets with fine wire .010" and compressed air,wd40 in air screw hole finger over air passage wd came out of fuel intake passage.put back on bike started easier 2nd kick ran for 5-6secs at fast throttle then died.any ideas? think carbs still blocked?i hate concentrics my monobloc on tiger 100 no problem

Sounds like a fuel issue, but if it was only blocked pilots you should be able to run it above idling speed.
Sure there's enough juice in the floatbowls, and the flow is OK?

[davidg]

hadnt thought of fuel flow float height ok.but put in fuel lines filters they maybe starving it of fuel.cheers

[Welsh Wizard]

check that fuel taps, some times these can cause restricted flow, ( particularly if they have not been in use for some time)

[davidg]

hi,thought i would eliminate tank and taps by a direct feed from container to carbs.stliil same problem.been suggested by Rick Parkinton of classic bike it could be ignition fault.boyer fitted.any more suggestions?

[Welsh Wizard]

if boyer crap is fitted make sure battery is fully charged and in good condition

[davidg]

battery good no faults.still think its fuel.

[davidg]

got it fixed at last cleaned out carbs again ran a bit longer.noticed it was running on timing side only so cleaned out drive side carb again then noticed it had no balance pipe,fitted one started it ur bloody reka.runs fine just fine tune.why didnt i notice pipe missing before blame it on vision express.

Should have gone to Carbsavers!
