Kick start on my 1990 suzuki dr 350 does not engage


Don't hold the lever in as you kick. It is designed to get you just past TDC on the compression stroke. Try this:

1. pull in decomp lever (it should stay down)
2. slowly move kick start down. STOP as soon as the decomp lever pops up.
3. return kick starter to the top of the stroke.
4. kick smoothly all the way to the bottom. (takes very little effort)
5. no start? return to step 1.



If it still problem try check the adjustment on the decomp lever. The lever should stay down until you rotate the engine with the kick start to just past TDC on the compression stroke.

I have a 2001 wr426. It has started fine since i got it 4 months ago. I didn't ride it for about 2 weeks and when I went to go and start it it was like it had lost compression? You can actually pull the...


sounds like a valve has stuck in the open position, or it needs the shims checked, also check the decomp cable is not holding the decomp lever open .
A push start might even free up the valve, if it does use an upper cylnder lube like moreys.
but the shim clearances are critical

Just changed valve shims and need toknow how to set timing


make sure the the engine is at tdc take the two cams and set the in the holder at the at a 9 and 3 position make sure the ex cam is in fount it has the decomp valve on it. You should if the cams are in the right spot you should see marks numbers on the cams that line up with the head and you should count about 15 pins from the top mark to top mark on the timing chain then install the chain ten and rotate the motor over slow if it turns over free the you are done

When try to start just bumps not wanting to turn over? Decomp?


Make sure your battery is fully charged and connections are tight. If your battery is strong, check the decompressor system (cables and actuator).

Shes a ***** to start


Assuming the bike runs well and this is just a kicking technique problem.
push the kick starter slowly until you get to the hard spot(TDC), pull the decomp lever, and push the kicker a little to get past top dead centre, then release decomp and give it a decent kick, should never kick back

'05 Suzuki Boulevard C90 sometimes won't turn over, usually when stopping during bike runs (still warm). Starts then runs fine if jump statred by another battery w. jumper cables. Local cycle shop has...


I've got a 2006 and just found this while surfing around...


Realistically, diagnosing the problem behind a bike that won't start, can be a frustrating experience, as there are many potential problems that can create the same symptoms. Here are a couple of guidelines to help determine the root of a "labored" starting problem, and by "labored", we mean that the starter motor kicks in and attemps to turn the engine over, but either can't get it over the "hump", or does so with a lot more effort than usual.

If your battery is over two years old, and you CONSISTENTLY have a labored start, then the first suspect will be the battery.

If she starts cold with no problems, but CONSISTENTLY has labored starting while hot, then the charging system should be checked. A grounding rectifier can actually discharge your battery while you ride. The battery can somewhat recover while sitting, so it may well start the bike while its cold, but then not be able to start it after only a few miles of riding.

If everything on the bike seems to be in perfect order, and you OCCASIONALLY have a labored start, or no-start, for no apparent reason, and with no perceived pattern, then very likely, the rear decomp cam is loose. A good test for this is to place the bike in second or third gear when it won't crank, and push it backwards a few inches while in gear, then try again. If it starts then, you definately have a loose rear cam. Pushing the bike backwards while in gear moves the rear piston back off its compression stroke enough to give the system a running start at it when you push the button. This will only happen when the rear cylinder stops on its compression stroke. Therefore, it seems impossible to predict when it won't start. Might be cold, might be hot, might only happen once today, but maybe three times tomorrow...This occasional no-start is the prime indicator that the problem lies with the rear decomp cam. (If the front cam were out of adjustment, it would NEVER start properly, as both cams would then be off their specs.)

Slight rattle in the valve cover


have you had the valve lash set recently? if you ride hard or race you should check this every 3-4 rides.. if valve lash is within spec, you may be hearing the fly weights for the decomp. system, this is fairly normal..if it is bothersome to you, replace the fly weights & springs if the parts are available, if not you may haveto replace the complete cam.

I have a 01 426 and it is really hard to start. I have put a new plug in it canged oil ,checked the valves they are right by the book...but it takes a lot of kicks to maybe if you are lucky to start...


G'day TJP..OK...Lets concertrate on starting procedure.Bring the piston up on the compression stroke , you will feel the kickstarter offering resistance.Pull in the decomp lever and bring slight pressure on your kicking leg,you only want to move the kickstart lever 10-20 mm.Close the decomp and kick her in the guts...show her who's BOSS...Be a MAN.Dont forget the choke,fully out when cold,but no more after a few kicks. Keep on try'in, you'll get it.I've seen guys kickin and kickin till the cows come home only to find that they have sooted up the plug and need a hip replacement.Once you do master it you'll have every man,woman and child wanting YOU to start their 4 stroker for them.I think there is something about starting procedure in the service manual...check it out. failing that you may have to clean the carby,IE, air ways,pilot jet etc Good luck...TJP98611.Please leave feedback if i've helped.
