what flywheel does it have? because the full sized one I have here has the T mark off...so if you set timing by it.. it would be a couple teeth off of time.

 

Inner Rotor.



Ok after about kicking it 100 times it popped once out the exhaust, then about kicking it another 10 times once out the intake. It has not done it again.

 

How did you time it with that inner rotor? did you double check it with a good full sized flywheel?

 

inner rotor came pre-installed. This motor ran before the V2

 

you pulled the cam from chain....you would have to still time it back.

How did you set time?

 

your positive cam isnt 180 off...cause thats what it sounds like. take head off and make sure one of the valves isnt stuck open or stuck closed.

 

Im sure. The valves arnt stuck, It builds compression. set cam timing off of TDC, then triple checked with it installed, its not a tooth off its dead on.

 

Ahh I know what it is...answer is two letters long. Starts with a Y and ends with an X. LOL

 

Did you put timing marks on the inner rotor?.....how did you set the time?

 

Check simple things.



Gas in the tank. Turn the gas on. Check your grounds.



If everything is right the way you say it is, there shouldn't be any reason why it isn't starting.

Not possible on these motors, '180 degrees off' is spot on. They fire every revolution.

 

lol yes theres gas, ground is good, harness is good. I get spark, Very good spark. I know it should be starting, but its not. Thats why im posting this.

Check your gas tank vent line. Does it fire at all when you kick it? You said you kicked it 100 times and it only popped once... That's electrical issues.

Vent line is good. Ive Pulled the new plug out and grounded it with it hooked up and it gets very good spark. By popping i mean out the exhaust. Im getting spark, good spark every time it needs to fire.

 

check the gaps on the inner rotor with a credit card. It may look like good spark but it might be blowing out. Also the inner rotors you can move the pick up up or down to retard or advance the timeing. First mark where you are right now and try moveing it either down ward or up ward as for some reason it could be like other people are saying off a few teeth some how.



For laughs get a new spark plug and see if that will fix it.

Gaps are set correctly on the rotor and plug. Its a good spark, I have played with different gaps on the plug also. I have moved the timing around. I have tryed 3 spark plugs.

 

its your IRK they are 100% junk toss it and you will be running in no time, also check your flywheel key it may be sheered to where you think timing is off. also pilot jet might be plugged

 

I have not had a lot of success with the inner rotors, but I am thinking like Blackwoodz...it is not possible to set the timing on a motor that has an inner rotor kit, spot on, 100% of the time, without either double checking with a stock rotor OR using a TDC indicator through the spark plug hole. If you have not done either one of these things, that is where I would start. I'd also check my valve lashes.



And Kurly is right...on the yx motor you can't install it 180 out...it is 180 on or 180 on.

Its not the IRK I have spark, how could it be inner rotor if i have great spark. Woodruff key is fine, i have checked. carb is clean.

I even put on a new outer rotor, still nothing. valve lash is correct.

 

try a stock full flywheel ignition and then go from there. I keep a known good honda setup just for trouble shooting.

 

It's easy to find true TDC with the head off ... With the piston at the top of the cylinder ... simply rotate the flywheel rotor clockwise until you see the piston only JUST start to move down , then put a mark on the rotor in line with the TDC index mark on the case ... then rotate the rotor counter clockwise until the piston only JUST starts to move down again and put another mark on the rotor in line with the TDC index mark on the case ... That'll give you both extremes of top dead rock over ... TRUE TDC is smack bang dead in the centre of those two marks where you should draw another line ... That centreline when aligned with the case index mark is where the crank should be held at when the cam chain is fitted with the mark on the cam sprocket pointing to the dead centre of the top of the head ... both cam lobes should be facing down at angles towards the combustion chamber ... In that position the rockers will be riding on the base circle (heel) of the cam ... and that's where the rocker clearances should be set ...



With everything set up right ... IF you have spark that is firing before or near the leading mark on the flywheel rotor , know for dead certain that there is fuel in the cylinder , and it STILL doesn't kick ... or it pops out thru the intake or exhaust ... and you know for dead certain that the flywheel key isn't sheared allowing the rotor to slip ... then you have BENT the valves ... and they're not sealing ...

 

Since you can't be 180 off on these motors....does it not matter which mark on the cam sprocket you use to set the valve lash?

 

check kill switch...it could be grounding out..happened over my way many times after a rebuild.lol
