Question about 2005 Suzuki Boulevard C50

1 Answer

How do you adjust the valves on a 2007 C50 Boulevard? I have pulled the tank and changed plugs. I have the Clymers Maintenance manual, but the valve covers sit directly under the frame of the bike.

    How much space do you have between the top cover and the frame, if there is at least 40mm then you could attempt to remove the cover, but if not then you might have to loosen some mounting bolts and drop the motor slightly. a few cm's makes a big differance...

I've got an 06 C50. It IS a very tight work space to adjust the valves, especially the rear intake valves. To give yourself a little more working room on the rear valves, move the chrome tube (located directly above the rear covers) to the side by removing the 2 bolts that connect it to the back of the rear jug.

Remove all of the valve cover nuts and bolts BEFORE you remove the covers and BEFORE you remove the spark plugs. This prevents the potential to loose them down in the engine, which is a whole other problem.

The VoluisaRiders site has A LOT of information on how to do this, someone a few years ago created a how-to for this task with pics and is virtually step by step. That is what I use (done it 3 times so far). Also there is a method for setting the valves without using feeler gauges, making the task MUCH easier, but that is a personal preferance,

I would give it a 3 out of 5 wrenches in difficulty, so make sure you know what you're getting into before beginning.

    Do you have that step by step procedure on a link or file that you can post/send me? Would like to take a look at that before adjusting the valves on my bike. Thanks.

Lost manual when should valves be adjusted 2006 C5OT 14000 miles?

The valves should be adjusted at the 1000 mile mark as they will usually tighten up as everything seats in, then once that is set the factory recommends checking them every 7500 miles there after. I have owned Suzuki sport bikes my whole life and after I personally adjusted the valves the first time after the 1000 mile mark they never went out of adjustment again in 30,000 of riding on my last two bikes.

Fuel tank &fuel system

If it is the 800 cc model, your fuel capacity is:

4.5 U.S gallons (17 liters)

There is no fuel shut-off switch on this bike. When the last bar on your fuel gage starts blinking, you are on your reserve and have only about 1 liter of fuel left.

I have a 2005 c50 suzuki it has a lot of valve or timing chain no

When correctly set, the valves can be quite loud on startup on these bikes, sometimes described as the "angry sewing machine". I would prefer that they be to the "loud" side than too quiet, as a tight exhaust valve can cause it to be burned from prolonged contact with the seat. The tensioners have been subject to fail- not universally, but it does happen- and that will be more of a knock from the side case that a rattle. The tensioners are self-adjusting until worn out.

2005 C-50 Suzuki Boulevard - A back fire occurs with the throttle open. Stock pipes never changed. One very loud backfire at about 30 mph winding/slowing down. No tach on board. Bike has only 4k miles...

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.

Fork height of C50 vs Harley fat boy

1) Can not find this spec.
2) C50 rake is 33 degrees, Fat Boy's is 32.
3) Many have had over 50k miles without any major engine work. Luck and riding conditions determine this to a large degree, but I would say that most need to start thinking about valve/ring work at 60K.
4)Valve adjustment recommended at every 7500 miles; about a 4-hour backyard job, but doable without any real specialized tools. (I've been letting mine slide for 19k, just because it's been running so good!) Cam chain tensioner failures have been reported, but this seems to be the exception, and the use of synthetic oil may lessen the chances, Problems with water getting to the rear shaft splines have prompted owners to pull them and add Molybdenum paste at each rear tire change, and this requires replacing the oil seal- about $11.
5) Depends on current mileage and price, but with a modicum of proper care, you could expect 50k miles of riding without major issues.
