Hi all, MJR & Stig, thanks for your replies. Not sure if it has a roll over sensor, will check that out. When I ride downhill it's usually steep and hairpin turns, so yep, I use some gas and sometimes not, doesn't make any difference to the problem. Curious is that it doesn't happen at any other time than on a relatively steep downhill run, then it continues on the flat for a while. But no problem accelerating on flat roads or uphill. I use the gas and it seems like a 2 or 3 second gap until the gas comes then it starves again and then the gas comes back again.
Before the accident this problem never existed!! Never had a problem just coasting down from big mountains, the gas response was always immediate.
We've checked all the vac hoses etc, cleaned air filter, checked the rubber joiner after the efi unit etc.
The bike was on its side on the road for a few minutes after the accident.
I stripped the bike down and made all the repairs myself, all cosmetic fairing parts etc.
Is it possible that the air cleaner unit has a crack and allows too much air in creating a negative pressure or maybe the efi unit has an issue after the crash?
It was a fair whack in the rear end and moved the bike from stopped position about 20ft 7mt. Most of the impact was taken by the rear wheel.
Cheers.
