Hey guys,
im here again as i am working on my bike again since ages.
so to start.. Best riding wishes to all of you!
the issue i am dealing with that got me to dive into my tools(shed) again i have is hat i have a feel that my bike doesn't idle nicely.. and i find myself riding with choke on to stay above the 1100 rpm, even after it is warmed up.
also i feel like the the main part of the choke lever travel is in effective (meaning that it does not increase the rpm)
so i am now going to clean the throttle bodies and my airfilter (found it to be dirty..) so either cleaning should make an impact already.
but i would like to try to fix this in effective choke lever travel part too.
i read the manual and it literally says the following.
"To adjust the travel of the choke cable, turn the cold start lever on the handlebars fully on and check that the arm (5) rests against travel stop (B).
Make sure that with the choke in this position the engine turns at 2000 rpm."
but when i engage my choke fully (the lever) it does not rest against the end stop at the end of the travel and the rpm of my engine is high (5000 rpm).. out of experience. haven't checked now in the garage exactly. when i not engage my choke it runs really low in rpm.. more like 900.. or even lower.
and the bike has the tendency to stall when i close the throttle completely (even when i need to change gears) untill the temp comes to a (normal) 70 degree C (160 F). anyway definitely more then when it comes out of "LOW"
so i have two questions. what should i do to make sure the arm comes to rest to the stop when fully engaged.. and will this solve the high rpm when fully engaged.
as you understand.. the in effectiveness at the beginning of the travel and high rpm at the end. leave my choke setting very delicate. which is a nuisance when riding with the choke on (which i need to other wise it stalls when i close my throttle)
Additionally. i find that my throttle has not much play (none really) and when i close my throttle. i feel like the throttle body really falls close (with a tap) and doesn't close gently. this is something i have not noticed with my st4 before. could be oke.. could not be.anyone any thoughts on this ?
kindest greatings.
