Coming from 2 wheels, I am a little shocked that the kickstarter is considerably smaller then my 05 CR250 2-stroke.....is there a way to fit a longer kickstarter? Or at aleast one that has more area for you foot/boot to catch on?
I have a 05 CR500AF and I would say it's slightly easier to start the cr500AF (does not have compression release btw).
Does having a 265 big bore kit really make it that much more difficult to start? Kicking over the 250R in work boots hurts, still isn't comfortable kicking it with MX boots on. I know as of right now my foot keeps slipping off as it makes contact with the pipe. Didn't know if someone sells a kicker that has bends in it kinda like a 2-stroke bike would.
Going from bikes to an R is a completely different game as your finding out. Short of welding on extensions there's really not any aftermarket options for a longer kicker. The pocket in the fenders will limit it to not much bigger than stock also unless you cut the plastic to clear it... The 265 isn't considered a bigbore but there usually built as high compression high rpm screamers so it might just take some getting used to before the kicker feels normal.... Unless you have an aftermarket cdi like Action69 mentioned than those can make your R a sob to start.
check compression. should be pretty easy to kick unless crap aftermarket cdi..yes they arnt real easy like birtbikes..stand up get it on a good stroke and kick straight down.my son starts his 431 in flip flops.
What's the deal with aftermarket cdi? Are they meant to increase spark at higher rpm but not good for starting. I'm willing to go back to stock if that helps. I'm looking to trail ride, no higher rpm needed. I'd have to guess that the last owner used this 250 as a flat tracker.
On average it might take 10-12 kicks to start. Noticable compression "POP" out the silencer after each kick....every once in a while I can get it to start in 1-2 kicks.
Pull the Spark Plug.....is it wet ? Dry & Black ? if so....you're rich.....Turn your Air Screw out 1 turn and try again with a NEW clean properly gapped plug (0.024")
Is this a STOCK carb ? Maybe the Choke/Idle adjuster is worn or out too far.
Is your Air Filter Clean and oiled properly ?
Hows the Spark ? White ? Purple? Could be a weak ignition
Pull off the Magneto cover...Is there an RPM Ignition advancer installed ? Timing might be too far retarded.
afterarket ones have too much inital timing and usually not enough total.so they kick back and then never seem to rev out.acts like it's rich but it isnt.oem only.
Shouldn't be hard to start a 265CC OEM cylinder, actually should be fairly easy. Most likely it's over compressed, plus no such thing as "as high compression high rpm screamers"...."high compression" does NOT produce a "high rpm screamers", the reverse is true. The higher the compression, the more limited the high rpm's become. Usually high compression engines are 'stump pullers', or intended for Low to Mid Range, not any sort of high rpm's.
If you're sticking with what you have, and it is a "high compression" engine & not related to BAD aftermarket CDI's, you may want to consider a CR Valve ('Compression Release Valve')...this addition will make starting much easier, push the CR Valve in, kick start and go....usually compression is reduced 35-45lbs, once the engine fires the CR Valve closes automatically. They work great...
Also the head might be bored alot my 254cc's head was bored to 23.5 cc i am pretty sure it has oem cdi and it is super hard to kick over it also had a cr head gasket i am 160lbs and i can jump on the kicker and it wont turn over.
23.5CC's is not a High Compression dome for an OEM cylinder at 67.50MM bore. Something else is not correct; possibly squish is set extremely low. The statement "i can jump on the kicker and it wont turn over" is very troubling, not good!
stock good compression should be 165-185.going with the cr or just the shim oem gasket it will bump it up to 185-205 usually.still not hard to kick over.
Going to a CR shim gasket will make it a bit higher than 185-205psi cranking compression. I have an OEM ATC head gasket & stock 86 head on a non ported 66.75mm 88-89 cylinder with a hotrods LR crank & its just a hair over 200psi according to my snap-on compression gauge.
I have 88 with ct 310. When mine wanted to fire, gave kick back and was being difficult, it was a combination of a bad cdi and fuel. Carb was lean and new cdi helped not kick back. The carb being lean was biggest issue. They tend to be very picky about fuel, oil, air mix and ratios. At least in my experience.
mr lee try to stay away from the aftermarket cdi.makes your machine run like crap and alot of kickback maybe a member will have one they can sell you or you can find a used oem cdi.take care and good luck.
Both Used OEM, and a New Batch arriving from Japan late this month. 86-7 & 88-89 CDI's. The New CDI's are Made by the same manufacture that made the Honda CDI's for the ATC250R's & TRX250R's, as well as the current manufacture for Honda CDI's on most if not all models.
This is the Third Batch BDT will be receiving for the past 6 years, all the rest have sold out quickly, they are EXCLUSIVE to BDT, you will NOT be able to purchase the CDI's from anyone else, and YES they will ship in a Plastic Baggy...if you don't like Plastic Bags; don't purchase one.
