Question about 2002 Honda CRF 450 R

7 Answers

Ability to kick start the bike

I can not kick start my bike because the kick starter locks and will not depress, almost as if it is building up too much compression and will not allow the kick starter to go down. After great effort can get it started first time but if the bike stalls it is nearly impossible to restart it. Is there an adjustment that I can make to fix this problem or does it need to go into the shop. I have owned this bike for about 1 1/2 months, purchasing it brand new and this issue surfaced a couple of weeks ago.

    Did not realize that this posted as a 2002 Honda...the bike is a 2009 Honda CRF 450R

  • macattack62 Jan 05, 2009

    This bike was accidentally posted under 2002 Honda...it is a 2009 450R and brand new

  • macattack62 Jan 05, 2009

    if it is a compression release malfunction is there somehow to check this or is there an adjustment?

    If you - for whatever reason - dont have warranty coverage, here are a few DIY tips.... however dont do any of the following if you have a warranty on the bike!!!



    First you need to see whats stopping it. Is it a jammed piston (Hope not) or when you rebuilt carb did cylinder fill with gas because float stuck (that would do it) or is it just the kick starter itself jammed.

    Here's what I would do first.
    A) remove spark plugs, if gas or compression etc is in cylinder(s)
    it will no longer stop piston movement and will spray out of
    plug hole. Takes 2 minutes right. TRY IT AGain....

    B) I assume you tried above and it didn't work. Leave plugs out and
    put bike in 3rd or fourth gear, Try to push the bike letting out the
    clutch slowly. Did engine turn, If so Its your kick starter..pull
    it apart.
    If Not, Then you either have a really bad jam between the kick starter and motorcycle engine/transmission or a stuck piston or crank etc.
    C) Try pushing bike in gear backwards slowly, Did it break free ?
    If so try pushing forward again. Still free ?
    If so try kicking over again a few times, did it jam.

    If its free when doing everything but kicking I would say you need to take kick starter apart, if it jams pushing then you have bigger problems and I would do anymore without tearing it down to see whats jamming.

    BTW, the new CRF450Rs start easier with less kick - no joke! Mesh the gears, and then give a light kick. the X model electric start would have been the better option. But thats neither here nor there.

As its the warranty issue in the bike its better to take it to the shop and it does have such compression issues in it that makes the bike hard to start.

It sounds like the kick start gear is sticking or the clutch could be dragging

pull the clutch in and see if thekick start arm moves freely

If it moves freely the clutch is working ok and the arm is not in a bind

you will have to pull the side cover to determine the problem

Put the **** in second gear and ush it to hear the motor turn over just to make sure the cylinders are not locking up

call the honda sho explain the problem then ask for any suggestions

If u fool with this problem yourself U will void your warranty, have owned allot of bikes, these shops will do anything to get out of a warranty repair, so let the shop handle it, also u didn't mention your weight or height, this bike has allot of compression, once the rings break in the cylinder compression goes up and it is harder to start, in any event let the dealer take a look.

Hi and welcome to FixYa,

Initially, problem could possibly be with the auto-compression release malfunction.

Good luck and Thank you for using FixYa.

    As the others have posted, you would be better off seeking warranty repair. For a '09 Honda CRF 450 R, decomp issues are either:


    • the plunger integrated with the cam; or

    • the decompression weight integrated with the shaft.
    Whichever of the two would require engine works.

Honda 125 innova kick start problem


Picture a lawnmower. Pull the starter cable with the lawnmower on its side. Envision the movement being the same on the kick start. Removal of the cylinder housing requires removal of the starter arm. Many scenarios the arm connects to a gear with a bolt. Recommend bike shop. So as not to damage gear.

Kick starter hit back strong..why??


That will happen on compresson roll back.
Try slowly bringing donw the kicker a couple of times till you feel it build up on the compression stroke.
Then turn on ignition and start the bike.

Most likely, you have a top end failure(piston/cylinder). Once you disassemble the top end, be sure to check for signs of loose or shattered bearings in the bottom end. Often, this can be the actual cause of the top end failure.

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.

Kick start is jammed


Put the bike in 3rd, 4th or 5th gear, the higher the better. Sit on the bike, with your hand off the clutch lever, and rock the bike back and forth to rotate the clutch hub. This might free up the lever. You will need to drain the oil and remove the right side casing to see and service the kick starter. If I recall correctly, there is a spring clip that allows the kick gear to engage the clutch hub. The piece could be broken, weak or out of position.

Please rate this answer. Thanks Shay!

Jamed kick start


Sounds more like a seized engine to me. When a kick starter breaks it will be when you're kicking it. If the engine died and the bike doesn't turn over with a kick it's probably locked up. Try pushing it back and forth in a higher gear and see if the engine turns over when you let out on the clutch,
