Scooterized, re-jeted, de-baffled WOW, throttle touchy now
OK i Just finished a bunch of maintenance and mods, valves adjusted, oil change, antifreeze change, de-baffle exhaust, re-jetted carb (Dynojet needle DN0106, 50 idle, 165 Main with emulsion tube all HD) and scooterized intake cannot believe the difference in power and highway cruising but as with anything there is a drawback at least for me and maybe you guys can help me out. I have my dyno-jet needle set at 2nd notch from top with 2 washers and air mix screw is at 2 1/2 turns, plugs after 400 KMS are nice and tan and there is absolutely no backfire from exhaust, occasionally I get a cough from intake when at a stoplight or intersections where I must completely stop and I blip the throttle (habit I suppose) but that is rare and the only hiccup when running, I know moving up a notch on the needle leans out the mix and down makes the mix richer, but not sure how that would effect throttle response, right now the bike is super responsive, maybe a bit too responsive, on the highway it's perfect but in town it seems that the throttle is way too touchy. I am very aware of over throttling and I am talking about fractional movements on the throttle and the bike wants to launch, hit a small bump at slow speeds in 1st, 2nd or even 3rd gear and that is transferred to my hand resting on throttle rocker and bike surges forward really touchy but very smooth on highway, make driving in traffic a real pain and I would like to dial that down just a bit, any suggestions would be most appreciated, BTW I have already done a 17T to 18T front sprocket swap and intend to do the rear swap to 40T at a later date, this will calm it down some but just put a new chain and sprocket set on last season and it's only got 1200K on it so far so it's not going to get changed for a while. Any carb tuning tricks I might employ would be appreciated.
