VGIS questions, i haven't give up.

Post by ntwdavid »

Dear all,
My VGIS activate at 4000 RPM, is there any low cost and simple method to make it activate at 3000 RPM?

i made it activated all the time, from idle to the max RPM. simply i removed the hose wich is leading to the VGIS :)

i did that before , i felt that by doing so my ride feel smoother but lesser acceleration.

now my VGIS is set to one quarter open all the time. It become fully actived at beyond 4000RPM. :p

its set to open at 4000 rpms for a reason, thats where you will have the most power. if you open it too early you will lose acceleration. if leave it where it is.

I ran two tanks of petrol , 1 with the VGIS hose connect and the other WITHOUT the VGIS hose connected..

I lost about 30-50kms per tank with the VGIS disconnected ( Butterflies open all time ) as opposed to with vacumm connected and butterflies opening from 4000rpm onwards... I did notice a slightly smoother quicker rev range with the hose disconnected. Although i do have a Pod filter setup..
