My mc28 is not running, is anyone have a cue?
My bike is sit in my garage more then half year, so the first thing I do is replace new spark plugs(radium), gas(91octane) and 2t oil(redline).
When I try to kick start my bike, I saw some smoke coming out from exhaust. So I think there is no problem with firing.
I kick many time, it still do the same thing, so I have no ideal wt happen to my bike.
Is anyone can help?
Thank you

did you check you battery?

my battery is new, purchase in mid June, and i check, it is good.

Try bump starting it, it's not unusal for them to not like starting after sitting around for a while.

I suspect the carbs are a little gummed up. Did you drain all the old fuel out of them before you stored it, and if not have you done so now?

Old fuel does go off and loose it's octane rating...

thanks guy...
i clean my carbs today, when i putting it back i saw one of the exhaust valve control cable broken. i think it is the reason cause the bike is not running.

It will still run with even if the powervalves are not working. Not very well, but it will still run.

sorry...i am changed..

Slightly off subject, but not....

91 Octane gas is way to low, surely that would cause detonation and eventually a terminal engine illness...?

My bike is not standard but also not greatly modified and I was getting mild detonation from 95 Octane and now only use 98 Octane.

So, although I haven't solved your problem I hope I can prevent a possible future one.

If I'm wrong let the slaughter commence.....

A couple of things to try,

Flick the kill switch on and off ten times or better yet pop it off and clean the internals with some contact cleaner

Do the same with the ignition - on and off I mean

Check all electrical connectors are hooked up properly, clean them with contact cleaner and check that each wire is connected. Some people like to pull the connectors apart by grabbing the wires and it only takes one to recede back into the connector block to break a vital connection.

Unscrew your spark plug caps from the wire that connects them to the coils. Clean them with contact cleaner and also check they fit nice and tight onto the spark plugs. Clip 3-4mm off the wire and screw them back on.

Spark - remove a plug check for spark.

Gas - clean carb, set float height, high octane pump gas

Air filter - nice and clean

Rule #1 FULL CHOKE - NO THROTTLE

If you play with the throttle whilst trying to start a reluctant bike you will just flood it and unless you leave it for at least a half hour you are wasting your time, energy and winding yourself up for nothing!

If the bike starts and then stops a few times or starts on just one cylinder this is normal for a bike that has been sitting, if it wants to idle after this then great but still don't **** with it!

Leave it to warm up then give it a slow gentle rev.

People just can't resist that throttle, it is like a brake lever when your wheel is out, a dick magnet!

Seen it as million times

In my area 91octane is the highest i can buy from a gas station.
Don't know where i can get higher octane in my area.
Is there anything i can add to increase the octane?
caffeinejoe90 thanks for your advice.
I will try it on Thursday.

No worries - your local auto shop (car or bike) should sell 'octane booster' which will up the rating.

I would avoid the mc21 flywheel upgrade if you can't easily get higher octane juice as advancing the ignition will only increase chances of detonation.

Good luck!

Perhaps Obama needs to invade another oil producing nation so you can get some decent gas lol

I have another MC21.
It sit in my garage for half year like my MC28.
When i kick start the bike, it starts on just bottom cylinder.
The top cylinder is like something choke up, like not firing correctly.
First i thought it may be the spark plugs, so I replace a new ones.
Then i start it again, it still the same problem occurred.
Is the top end need to be replace, or the card need to be clean?
It is running pre-mix.
thanks
