Starting issues with a 3 year old yamaha vstar in hot weather . suddenlys?

I have a 2015 yamaha vstar 950 ... changed oil regularly .. just change spark plugs after the problem started with needing throttle in heat..

my question is.. is there an easy adjustment that I can get changed at the shop to fix this .

my experience with trucks was when it got hot an the fuel filter was clogged then it caused problems

so changing fuel filter is fine on a truck and it works fine

... on a motorcycle is there a injector cleaner i can use I use premium gas and the yamaha additive for fuel

is there an easy way to reliably start with this issue like holding key on throttle a bit and hold it or throttle and let go .

its just having trouble starting most after a 20 minute highway run at 100 km/h or more so I think its more than just a setting it think its something clogged

    Start with injector cleaner, Top Tier premium gas,.

    If she still give you this malarkey, try the diagnostic in the owner's manual. Or go to dealer and have codes read. I would suspect, beyond injector cleaning, a bad ambient temperature sensor. Usually right in intake manifold or plenum.

    Source(s): Ref: Live where it is often 107 right now and have '06 VStar 650, carbureted. Runs fine. Also have a newer bike with Delphi EFI.
