it's just the way it is, and depending on outside temps, will determine how long to keep the choke, been in the low 60's here, choke off with-in a halfmile and fully hot a warm with-in 5 min. and as far as choke, it's either on or off for the hsr
. As far as pilot
, my belief is no need to go bigger than the 25.
I think one of the issues is that people tend to think that a carbed bike should be up and running perfectly in 2 mins. Ain't gonna happen! And the colder it is, the longer. Keep in mind, the FI bikes has the computer compensate by adding more fuel when it's cold and dictated by various sensors and will continuously monitor and make fuel adjustments as needed. Carb
is manual operation, the trick is to only judge performance only after the bike is fully warmed, then learn how the bike reacts to when cold untill the point of fully warmed. Only time I do any adj. and that is only the pilot screw by richer 1/3 turn is in Jan to Mar.
there ain't no heater for the HSR, the stock carb heater there is a temp sensor behind the left side cover, that turns on and off the heater ckt.
Seems also a lot of people forget about the idle adjuster, regardless of carb and tend to use the pilot screw to dial it in. The 2 work hand in hand, the important thing is to have a start point. HRS tuning manual calls for 2 turns out on pilot screw, once the engine fully warmed will be final idle adjust. At that point you can do an optional pilot screw tweak by turning in till a change, then turning out to a change then set it in the middle of those 2 points. Now, since the bike is fully warmed, this is where the idle will be ideal. don't expect ideal for the first start of the morn tho.
