    Is "hard to start" fixable?


    My old ass tired 2004 CRF250r is stupid hard to start, especially when hot. it needs to be in just the right position and get a STRONG kick in (usually multiple) to get it going. Is that something that can be fixed? Does a tired engine just get harder to kick over, or is it just the nature of the beast.

    I used to ride with a few people that had them, I don’t recall any of them starting easy, even when new. Can’t tell you if there is a fix or not, but it’s known as a hard bike to start

    I fixed it with my rmz450 by selling the POS and getting a(nother) 2stroke

    (Seriously, the hot starting was the only thing I didn’t like about the bike, but it’s not easily solvable)

    How is the air filter? How are the valve clearances?

    Ironically, and somewhat surprisingly, an old dude at NHMX taught me that it's easier to kick my CRF250R with a smooth, slowish kick than it is with a hard, START RIGHT FUCKING NOW kick. Of course, I learned this lesson with a bike stuck at the starting gate, and entered the race one lap down...

    My RMZ450 starts first or second kick every time. No matter how long its sat.
    But I did buy a KX250f, so I dont have to deal with kicking this damn CRF, but my friends do.

    I shouldve been more specific, it started fine cold, it was mid moto hot starting after a crash or stalling it that made me want to search for a lighter and can of gas, once I caught my breath

    Too rich?

    Has it gotten harder recently? Or always been difficult? I thought some bikes were more prone to it, but if it used to be better then something's changed. If it's the loaner bike, are they dropping it, giving it a couple wimpy kicks, then you get a try but it's already flooded?

    i don't know anything about these bikes, and not saying you do this, but i'm always amazed at the number of riders that try to start a 4T like a 2T by twisting the throttle open as they kick violently.

    no gas + smooth, full stroke kicks is usually the way (as number9 pointed out)

    my XR250R was a bitch to start, too.

    My KX250F was a beast to start hot. I did get it down though.

    I use the same technique 2T or 4T - Roll to TDC with the starter, edge it just past then reset the kicker, and then give it one good boot all the way through the stroke. Hand on the throttle, squeezing the brake to keep positive closure. If after a couple kicks it doesn't come to and my gut says it'll help, I'll try a WFO kick but that's on a case by case basis. I'm also used to non-EFI / Battery sporting bikes with early CDI/TCI that need swift kick over speed to get good spark more than trying to overcome compression/etc. Older points setups or newer battery backed ignitions are more forgiving.

    Richie, if your 250R has ALWAYS been a pig, it likely will continue to be. If it wasn't this bad to begin with it can be restored to that state once you identify what needs adjustment/refurb love. Does your bike have a hot start lever / knob?

    Re: Is "hard to start" fixable?

    Valve adjustment and new rings if it has been a while, maybe good place to start.

    My DR is notoriously a tough start but after months of training in the black arts of kickstarting (eg. sweating and panting in the woods) I got it down to a few kicks under almost all conditions. Aside from setting idle based on temp, idle air control, and having it jetted for the temps, I've learned not to waste kicks. A few failed kicks and it just seems to get harder from there. Get it just past TDC and give it one helluva smooth hard kick. Also not inadvertently twisting the throttle too much and dumping a bunch of fuel.

    Its always been a bitch. But it hasn't been ridden much lately, and seems to be a bit worse lately (only took it out once), but that might've just been from sitting. And yes, hot start lever, doesnt seem to be too effective.

    Old gas and possibly partially clogged pilot jet might make it harder to fire up.

    If you're talking about motorcycles, yes.

    If you're talking about life motiviation, no.

    Iridium Spark plug maybe 1 level colder

    Does it have automatic compression release cause that could be funky

    And as always 2 tanks of double dose SEAFOAM

    I wish i knew the secret. It wasn't a 250 but i watched Jetta J miss too many races because his would not restart.

    Emily's KLX was a bear in a half to start so I put a primer on it.. That cured that evil bone crushing machine. A couple quick pumps and it would fire right up. Pretty much no matter what..

    It might be worth a try.
