Hi Mohawk Are these the starter valve settings use have used? i set them as per the manual, but based upon what i have learned on this forum, i have got the MM on 3 & 4 the wrong way round!!! so im gonna redo these at the weekend, Many thanks Jon

Thanks everyone for all your great responses - i am going to try the 'reverse' starter valve sync (as i had do this the way the manual said) then try another VFR (Andy Bolas of the VJMC) and then i will have the injectors cleaned, once i have the courage to take off the throttle bodies! Thanks so much again, I now know where to come for great advice. Jon

hI I have recently purchased a lovely 18k miles 1999 (pre cat) 800fi. I must admit to be a little disappointed with the bike; so i wanted to see what others thought - this is the only one of these i have ever ridden, but do also have a 1986 VF500. I have found the VFR motor to very lumpy, worst at low revs (under 5) but also at higher revs; this seems to get worse in warmer weather. ive serviced the bike, inc a plug change (these were brown in the middle and a little dusty on the edge. Also synched the starter valves and changed the fuel pressure regulator. I was really expecting it to be turbine smooth, not thump like a v-twin! Is it normal for these motors to thump like this? or is there something wrong (no EFI codes showing). What are your experiences of this motor? Many thanks Jon (UK)
