Sluggish on start

[RicksF6]

My 1998 Valkyrie is sluggish on the start, almost bogging for a few seconds and then takes off, the idle is set at 800-900RPM. once your on the road it runs fine just stopping and going? any ideas on whats wrong.

Sounds like dirty low speed jets, add a mega dose of techron or seafoam and go for 30 min low speed rides park the bike and let if sit for a few hours or over night between rides, but keep the techron/seafoam added to the fuel until it cleans up.

Has this just started after prolonged period of not riding?

Yes it was parked for 3 months or so when i bought it, I'm a new Valkyrie rider (sold my Goldwing) I ran some carb and jet cleaner thru, but didnt have any affect, will try the seafoam I hear it works great...Thanks

What kind of petcock and does it have an in-line fuel filter ?

[RicksF6]

 I'm not sure what you mean about petcock, and it does not have a fuel filter. (but it is on my to do list) for this winter.

the idle is set at 800-900RPM

That is the barely minimum recommended, actually 800 rpm is too low.

You would have a more responsive motor with the idle set @ 1000 rpm.

If once the engine has been run a bit and the sluggishness goes away, and, if the engine runs smoothly and accelerates smoothly from just off idle to 2500rpms [low circuit] and beyond [high circuit], then it seems like it just may be slow to first deliver fuel upon start-up. That could be a petcock [fuel valve] or fuel filter issue. What kind of petcock do you have ? Vacuum or manual ? If vacuum, check the vacuum supply line/hose [ on #6 cyl] and if good then the petcock may need repair.
I would also recommend continuing using some Sea-foam for a couple tanks.
