I have a 2006 Suzuki Boulevard C90T with abouit 19000 miles. About 6 weeks ago, it began intermittently not starting. It didn't happen often and when it did, I usually just waited about 5-10 mins and it would start. Until one time it didn't (resulting in a tow to my shop). My mechanic is swamped and so was booked for work four weeks out. So to get my bike back to me quicker than 1 month, he admittedly didn't diagnose rather he just took apart all of the connections to things like the kill switch and the kickstand switch and cleaned them and put them back together. She started beautifully for the past month until today. I went for a short ride (30 miles or so). Within 1 mile of starting, the F1 and oil lights flashed on and the speedometer started jumping all over. As soon as I tapped the brakes that stopped. About another mile later, stopped for gas and then it wouldn't start (like it acted several weeks ago). However, within about a minute it started up. About a mile after that the lights/speedo thing happened again, stopping when I tapped brakes. From then on she ran just fine for the next 25 miles or so. I didn't shut it off at all during the ride after getting gas and when I got home, I shut it off and then tried to start it about 10 mins later and she fired right up. I'm hoping to take a trip next week and don't want to be stranded. I also don't want to wait for weeks for my mechanic to fit me in. Help!

I think your mechanic checked all that for you already. If he had his hands on your bike, and he cleaned connections, checked plugs and all. If there was a problem he would have found it going through your bike the way you described he did. Now I think your problem is with your battery or the main relay. This is where I would start if this problem where mine. Check the battery, check the main relay once the problem shows it's self again. Get a 12v test light, learn which wire should be hot when you press the start button. (check the relay for voltage coming from the start button). I am hunting up a diagram to further help you.

you probably have a bad ground connection somewhere, and will just have to start checking all the wiring you probably have a bad ground connection somewhere, and will just have to start checking all the wiring
