My bike was starting hard in fact the last few

the starter motor is probly toast or the gears connected to it--u need to inspect area w a service manual-can findum online ir library--or bring it to a private mechanic not a dealer------------try push starting by puttin it in 3rd gear w clutch in-then run w bike and pop clutch-caution wear a helmet and footwear

Push start the bike in gear. accelerate to about 10mph. Slam on rear brake hard. Try a few times as necessary.

See if you can push the bike with it in gear and the clutch lever pulled in. If the clutch is stuck, push start the bike, jump on, get to about 10 mph, pull in the clutch lever and hit the rear brake hard. This will usually break a stuck clutch loose.

Check the left side cover and make sure the starer clutch hasn't come loose from the shaft. Sometimes Suzukis will do that. If this is the case, don't just retighten the clutch. Take a center punch and put a few dots on the tapered mating surfaces . Add a LITTLE red locktite and retorque.

You have a bad switch somewhere - either the clutch switch in the clutch lever or the kickstand switch is bad. Of course I had a blast that had a sloppy connector at the back of the key switch that did all of the above too.

It's a pretty good guess, but there are a few things I would check first. I believe that bike has a wet clutch, so check your oil level first. I can't remember if it's a cable or hydraulic clutch on that bike, I would have to assume hydraulic, but there is a fluid reservior on the clutch if it is hydraulic. As your clutch wears, your fluid level will go down. So check that as well. If it's a cable clutch, then check to see if adjusting the cable does any good. Either way it sounds as if you're going to need a new clutch in the not so distant future so get yourself a manual and study up on changing the clutch. It's not as hard as you would think and it will save you a bundle doing it yourself. Good luck.

locate the starter motor solenoide & hook up to the positive terminal there! & the earth to the engine or frame ok

this could be really bad or really easy. first, lets hope its vapor lock. take your spark plug out and see if it will turn. if yes, kick it a few times and replace spark plug. if not then we need to see if the kickstarts malfunctioning or the motors lock. put the bike in about third gear, grab the clutch and pull it in, now run beside and push the bike with the clutch in, get some speed and dump the clutch. Hopefully the engine will start turning over, in fact if you have the switchs on you can start the bike this way. If the engine does not turn over like that then you have a drivetrain problem, without seeing the bike theres no way to pinpoint it. Lets just hope the steps above work and you dont have any major problems, good luck.

I have a 2000 Vulcan Nomad FI & had a very similar problem. In fact, it's a very common problem with these bikes. I fixed it by replacing the Clutch Spring. (As Described here: http://www.gadgetjq.com/clutch_spring_replacement.htm

It cost me $40 and 3 hours of time with an impact wrench.

A leaky slave would be more likely to give a soft lever. What you're describing sound more like a problem with the return bleed in the master. Have you made any adjustments recently?
