Misfiring and losing power

I have a yamaha 125 xvs dragstar and after runing for only a short while the engine appears to start misfiring and losing power.I took it to a mechanic who claims he tried a new coil on it but it made no difference. As to wether he did or not i am not a 100% sure. Does anyone out there have any ideas as to what i should do next?

Check the connection of the ignition coil and the spark plug then let your mechanic check your cdi unit.

Anyone gotta yamaha dragstar xvs 125 workshop manua?


Hi, Anonymous the vast majority of service, parts, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 sometimes more and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, then there is eBay where you may be able to find what you need at a very high price because of its age and rarity. Most of the "FREE" manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. To download your manual please click on the blue links below. Good luck and have a wonderful day.

Does the xvs 125 dragstar have a fuel pump fitted or are the carbs gravity fed


It's a vacum fed pump. When in the 'on' position the pump will only feed fuel to the engine when the engine is running. However, when switched to the 'prime' position the pump allows a free flow of fuel to the carb. An owners manual can be found on the Yamaha owners club forum. Hope that helps.

02 Yamaha xvs 650 dragstar classic that misfires when it warms up


First I would change all the spark plugs, and if that didn't make a difference then it sounds like the coil(s) are warming up and breaking down........when it starts to skip take a good pair of pliers with good rubber on them and pull each spark plug wire, when you get to the one that the running doesn't change then I would replace that particular coil
