Found myself with an hour to spare last night and NO RAIN!!! Decided nothing to lose by trying as am really not happy with rideability at low revs/traffic/low speed trundling and although in an ideal world there would be no traffic.... well anyway, did option 1 last night and popped out for a ride, there is definitely an improvement.. not sure its life changing but is better,wouldnt say there is more torque either just nicer to ride, will need to try with pillion for fair comparison as thats when I really notice the snatchiness and jerking. whilst I was out I fiddled with CO settings to try and smooth out the light throttle... ie 2nd gear 2500rpm constant speed where it surges like crazy back and forth, have checked with Yam who say bike does not need the recall for TPS as they had it sorted by my chassis number... Anyway initial CO was set at 30 and 19 which goes somewhat against the theory that C2 should be set a bit richer... tried richening both up to 35 and produced a smoother low speed response again although not as noticeable as airbox mod, eventually settled on 20 and 20 and see how that goes, dont want to be too rich, checked with my old man who also has a 900 and his is set at 18 and 17... will probably never know unless I can lay my hands on a gas analyser whats right!
So overall a
for the airbox mod, and
for resting my leg against the exhaust whenI got back having removed bike trousers... it smarts a little today!!!
Stoph.
So overall a
Stoph.
