needs the carbs cleaned out, and possibly some new spark plugs. If it has been over 4K since the plugs were changed, they need replacing also.

For pollution control, the bike is equipped with a pair valve. It injects air into the exhaust to burn wasted fuel. Many companies sell block off plates to remove the pair valves since they are so annoying.

Possibly if too full oil is getting to combustion chamber? Have you pulled a spark plug to see what they look like? You should check owners manual for correct procedure on addin/changing oil. I always recommend the shop manual for usually under $15 at auto/cycle parts stores.

Drain the tank of the old fuel completely, try to drain the fuel lines as best you can. Whilst the tank is empty, if you can remove the fuel pump and clean out the filter for debris or gunk. Pull out the spark plugs and see if they have fouled, don't try cleaning them just replace. I have found once a plug is fouled, it is best to just bite the bullit and buy new ones as issues can happen again.

Even though you probably don't have that many miles on the bike, or if you do have a lot riding time on it, it sounds to me like you need a valve adjustment. That's a high reving bike for that engine that works pretty hard so you might have 1 - 3 loose valves.

Engine cuts out


Try this. When you get to work leave the bike running and turn the fuel selector knob to off and let it run til it cuts off. It will drain the fuel from the carbs and trap the rest in the tank. It removes the air bubble in the lines problem so when you get ready to leave, switch the fuel on and wait a few minutes then crank her up and ride.

Backfiring on decel


If this is a new condition and you've not worked on the bike recently, I'd try a dose of StarTron in the gas tank. It will eat the sludge that grows in fuel systems exposed to gasohol. Put it in the tank, ride a few miles to get it into the carbs, and then let it sit overnight. It has special enzymes in it that do the job. Seafoam is a good product but is not designed to clear bacterial sludge.

2007 suzuki boulevard c90t. Starts right up no problem, but only runs for about 5 second then dies. Will start right back up, then shut off again.. So on and so on


Hello,

It sounds like your bike is starving for fuel. Check your fuel pump (pull the outlet hose off and try starting it) and your fuel filter. Also check your carb lines to see if fuel is constant at the carbs.

Try these things and if none of the above works, reply to this post and let me know what you discovered so that I can determine the next steps you need to take.

Hope this helps. If you find this information useful, please vote on this post. Thank you.

Regards,

Oz
