Title: S4RS running troubles - HELP! Post by: CafeBlack on June 18, 2016, 11:01:49 AM Hi guys
New to the forum but not to monsters. Currently running a 2007 S4RS (recently purchased). Love the bike but having some running issues. Appreciate any help or links to similar questions. Been searching all morning but can't find an answer. Basically when I start her cold she runs fine. Idle about 1500. However after a 15 minute ride, if I stop (for gas or something) she won't start again. Takes many attempts and will continually cut out until I get going again. Any ideas? Thanks, Nick Title: Re: S4RS running troubles - HELP! Post by: DucRS on June 18, 2016, 01:15:44 PM Fuel filter?

TB synch, fuel trim, TPS, valves, fuel filter, fuel lines, etc. Title: Re: S4RS running troubles - HELP! Post by: Howie on June 19, 2016, 04:46:09 AM Yep, start with the basics.

Booked in for a full run over by Ducati Santa Barbara on Saturday. Will let you know. Title: Re: S4RS running troubles - HELP! Post by: koko64 on June 19, 2016, 04:57:22 PM [thumbsup]
Title: Re: S4RS running troubles - HELP! Post by: Bill in OKC on June 20, 2016, 08:40:34 PM If your bike has a DP ecu, the idle trim could be set too rich. Mine did that and it was explained to me that the ecu goes through a enrichment cycle when first started even if the bike is warm. If the idle mixture is too rich the bike basically is flooded with fuel until the enrichment cycle is done or you let it cool off and start from a cold engine.

Had the exact same issue a couple years ago brought it in to GP in San Diego for a full service TB synch, fuel trim, TPS, valves, fuel filter, fuel lines, etc. and problem disappeared |
