250-500cc 2012 wr300 kickstart issue

I'm 5'8" and if I could get the old school left side kicker so I could stand next to the bike on the left and kick it with my right boot, I would love it!

correction, 6'4"

assuming your engine is in good condition, assuming your ignition is in good condition
these can both be checked using simple tests, is the spark good if so ignition is OK, is your commpresion such that getting it past TDC is hard your engine should be fine
if the bike is fairly new then reeds should not be an issue
so we look to the carb, the jetting has little if anything to do with starting it, if your engine is worn to the point it will kick fast then it's possible you might be starting into the pilot jet but otherwise typically starting has to do with the idle air screw, it allows air to feed behind the jet cucuit at low speed and most definitely affects starting
if your bike won't start and your plug is dry screw it in if wet screw it out
tip: the starter enricher is for pulling fuel to the back of the slide, the best speed on the kicker is slow to take advantage of the reed pulse
I have had great results over the years to,, and this is my ritual, turn on the fuel, put on my gear, lift fuel enricher , slowly cycle engine twice, turn off enricher, push just past TDC and kick it like you mean it, typically it fires right off
so what we did was pull fuel into the intake, then suck it with air into an engine that shoul start
altitude and temperature will affect starting if hot out, one cycle kick should do the trick and cold 3 would work, or just adjust the air screw to compensate when it's colder you lift the needle and run a bigger jet so screw the air screw in to mirror that
when you have a problem always start with the basics

my 2012 WR300 had an intermittent fault with the stator from new.spark 3 times,weak spark 2 or 3 times,no spark 2 or 3 times etc etc.still did not start easy,then found the R_little post,now it starts easy despite the short,high kick start lever.i am 6 foot & have to stand on foot pegs

i had lots of probs that a warranty replacement of the stator mostly fixed.check consistency of spark.2011 to 2013 2 strokes have ducati ignition made in india.i wonder if the 2010 & earlier fits/works.the more i look the more probs i hear about.

I have an 09 I was never able to get mine started no matter what I did, kicked it til I screwed my knee up, rolled it down the big hill, even towed it, no go. Ordered a PWK started 2nd kick.

I've been riding this bike for 3 years and It's still a tough bike to kick even though I'm 6'2" 195.
