Various problems with TW "acceleration"
I am having in the recent two days some problems with my 1993 TW
Basically when I am in third with a steady throttle (I even use a lock mecanism to make sure my wrist is not into play) the TW start to do a bit of back and forth like if I am super slighty pulling and releasing the throttle, it's suddle but it's there and no other gears do that, but I am constantly accelerating and not mantaining a steady speed the "problem goes away"
Also I am noticing in 5th gear that when I am at kinda low speed (I use a 45tooth sprokect) and when I am around 50-60 if I turn the throttle to the minimum possible to trigger the trottle the bike will start to slow down as I am out of fuel (impossible because I made a refule just 30 minutes ago)
this happen basically everytime
Also sometime looks like the bike has some "spikes" when I accelerate or have a constant speed, like I am giving a bit too much throttle but actually I am not
the bike has 50.000 km and I changed the oil 1 month ago, together with oil filter only in the last two days is doing this problem
what could be the culprit?
