Hey guys,
Just wondering about kickstarting the 250r when its cold or not warmed up. It takes me a bunch i mean a bunch of kicks with the choke on just to start it when its been sitting for a day. When its warmed up when im out in the pit it takes 1-2 kicks. The motor and everything was just rebuilt all new parts and everything. I was wondering if there is a special technique or some tips i can use to start it a little quicker when it is cold like fast repeated kicks or hold half throttle etc..

Thanks alot guys

i just bring my piston up to tdc and it starts with in 2 kicks. but after not using my 20 for 3 months it takes about 4 kicks to start it. so it only takes about 5 kickcs max to start it. and i have a virgin cylinder.

yeah i have a pretty tight motor like 265 powervalve bored to 300cc so do u think all the motor work would cause that or nah wait sorry im like semi retarted but what is tdc lol thanks

tdc=top dead center.

that is when the piston is at the top of the cylinder on the combustion stroke. on two stroke motors that is every time the piston makes it to the top of the stroke by the spark plug. on four strokes it's everyother stroke, but in both cases it's when the piston is making the compression.

ooo alright thanks

ooo alright thanks

its probably a jetting issue. when its real cold out i give mine a couple quick stabs with full choke and no throttle and it fires right up. i cant give it any throttle right away or it will stall though.

I would also say that is a jetting issue. Mine started fine and then I had problems when it started to get cold. Then when I got it ready for the ice and re-jetted it it starts in like one or two kicks. Never more than 5. And that's in like 10 degree weather.

oo yeah true, i actually just got the bike from florida a couple of days ago i assume its pretty warm down here, up here in jersey its been in the 30' 40's and sometimes 50's..might rejet

check these things for starters ...basics first always
make sure ya got spark @ plug
make sure fuel is flowing to carb & carb & air filter are clean
make sure gas & plug are fresh ..& choke is clean & works properly

even if main jet was a little off it start should ok ..but the performance would suck

 

[Tubsytmac]

yeah i think i got it now, i checked all that stuff put a new spark plug in and i just do this fast repeated kicks and it starts up in no time..thanks guys

 

[2R's]

repeated kicks ....hmmm,

this could be a sign of low compression or perhaps a not so good carb/jet set up
or even weak electrics .. so until you spend time testing , some trial & error &
figuring out which is the case ..glad to hear it starts
a better set up will start easier & save you leg

repeated kicks ....hmmm,


Ya fast repeated kicks , I would say low compression for sure. Had a banshee that took forever to fire up. After a tear down it had a fried piston and dead cylinder I have a pic

 

[Tubsytmac]

actually my compression is 225psi, just got it checked yesterday, one of my local atv repair shops said to try it with a 50/50 mix with race fuel/hi test(supreme at the gas station) gas because it was bogging 4th gear and on

With that much compression I'd think that you would want to run straight race gas with a quality pre-mix. Just my $0.02.

Ya that's awesome compression. Definetly in the race gas zone.. You don't have detonation at all.

 

[sictrxr]

yea my 330 is in that compression zone i run stait vp c12 mixed with belray h1r and it runs great

so what the latest dude, still haveing starting problems??
