Carb rebuild service?

<< < (3/3)

JezzaPeach:
Many thanks Ted. I was thinking of vinegar as well.
Trigger and Delta all noted. I’ve done a fair bit to them all and agreed. This is the only real issue now and I may need to repeat with 1&2, and fuel flow I’ve sorted. If the polishing doesn’t work a full rebuild will be on the cards.

Nurse Julie:
Send them to Matt Harper at Harper Ultrasonics.
I could be wrong but I think Gerben may have retired.

I only just saw this still posting. I thought mine were leaking from the float bowls but it was the fuel pipe T pieces 8 o rings all along. Just in case.
PS carbs off tips: air filter box out. Clutch cable free (if 500/4) Back and front carb clamps off. Plenum back 1/2 inch. Strip of wood across the back of the head to use a big screwdriver to gently lever the front rubbers. Lots of wiggling. Reassembling, a touch of red rubber grease in the rubbers to help.
New fuel hoses from DS.
I also found lowering the floats slightly has stopped intermittent ‘soggy blip’ on down changes, and stalling, due to too much fuel being sucked through.

Outrunner:

Thanks Julie, just down the road from me. I’ll certainly given him a call.

Matt has around a 6 week lead time before looking at the carbs, after I messed up my rebuild I took them to him, I believe it was £220 + any parts
