Re: starts bogging 4-5000 RPM
Is this bogging down still occuring after a run at 140kmph or just at any time?

Re: starts bogging 4-5000 RPM
it was fine for a few days, can take her all the way up the rev and speed range,it now happens everyday after about 20min ride, bogs down and I have to ride under the 4000 rpm mark, the bogging is through out the rev range after the 20 min

Re: starts bogging 4-5000 RPM
my 10 rand is on the vacuum hose being weak and collapsing when hot..which will reduce fuel flow..
So, check that out bra!

Re: starts bogging 4-5000 RPM
Checked the tank breather, its fine, on the way to work this morning I noticed that the bogging started same place as yesterday and around the same corner, so I turned around and went around than same corner again and guess what the bogging went away so long story short I seem to be having an electrical problem, I must admit that corner has a bad dip in the road,
any suggestions where I could start looking ,

Re: starts bogging 4-5000 RPM
Is the "bogging down" a loss of performance similar to running onto reserve or is it a misfire where some of the cylinders cut on and off.
