2006 King hates me

[crisscross1]

I just went out and fired it up ran good, then all of a sudden it quit , and it sounded like a chain. Has any one have this problem? It wont start now, just wondering if the chain inside broke and now the timing is off. I haven't taken the head off yet, but did take filter off and seems to poof poof out the breather hole, like timing. Is there a quick way to check the timing with out removing the head? while I wait.

You mean you think you broke a chain? As in timing chain? Usually really bad things happenwhen it breaks throws everything out of wack. Take out your spark plug and lightly hold your finger over the hole and see if you have any compression. If not ugghhh you will not be happy. If you do have compression do you have spark?

 

[crisscross1]

Ok went out and tried it, It has spark and compression. So I poured gas in the breather hole, but still no fire. How do I check the timing with out removing the head or is this possible. Any more ideas would not hurt. Can you not check the timing by putting something like a long pencil in the spark plug hole, and bring it to the top and remove the timing cover and see if it lines up?

That won't tell you if the timing is out on the cams though. It could have jumped a cog and cams see out. I would pull cam cover and check your markings.

 

[kbrunlees]

Busted tensioner maybe?

ok now that I took it apart there is nothing wrong with the chain, I think the chain noise I herd now is when you stand by the quad at 1/4 throttle and shut it off, you can here the chain go around. It must be electrical, but I do have spark, and it turns over and over, I'm confused.

They don't have to break they can stretch over time .They can stretch enough to throw the timing off.Your tensioner can also get weak or sieze all together.

 

[Canadianking]

Is the timing still lined up? Could be your fuel pump as well. I would check both them. Does the fuel pump cycle when you turn the key on?

 

[crisscross1]

I just checked the timing, it is all good, lots of spark, and you can smell the gas, with the throttle wide open it seems to puff out of the intake, checked the tp sensor good, I don't have a fuel line tester, maybe it 's not enough fuel. It seems like it wants to start but just wont catch. I'm at my wits end any more ideas.

 

[Canadianking]

Not sure man. Do a compression test. Check the oil for signs of gas. Could have bad piston rings and fuel is bypassing.

 

[crisscross1]

I already put piston and rings in, I just read that the pressure needs to 43lbs so I need a gauge

 

[Canadianking]

That's all I can think of maybee a weak fuel pump and not putting out enough pressure or lack of compression.

 

[doorfx]

If it is puffing out the carb
1-severely flooded
2-out of time
When the timing mark is lined up it could be on the exhaust stroke.You have to make sure you are on the compression stroke.When you are on the compression stroke your valves should all be loose (in spec.) That is how you check your valve lash and ensure your timing is correct.I am pretty sure there is no adjustment for timing on that motor so it goes back to what I said earlier.If your tensioner is hooped you could have jumped a tooth on the chain.

hey man may not be the problem but i had a simliar one you did and found it to be a sheared time key, id look there cuz i had all the same problems you did and replaced that key and reset time and runs like a dream now, i had the problme on an 05 bf750, hope this helps in some way, cheers

 

[crisscross1]

hell I checked everything I could do and could not figure it out, so in she goes to the shop. I triple checked the timing, lots of spark, pulled the fuel line off lots of pressure, checked the injector, it must be ecm or ..........how knows.
thanks for all the input.

 

[crisscross1]

Just thought I would let you know what the out come was. The cam gear had turned on the intake cam, no bent valves or other damage, other than to my pocket $1000. for GW cycle to find the problem and wait for the back ordered cam from Japan. Thanks guys.

 

[kingkris06]

ouch , was that cam made outa gold ,
cant you try pin it?

 

[crisscross1]

this f n machine is really starting to piss me off, i paid for it to be fixed took it home fired it up rev it up twice and zing, the same problem again. I asked for the money back but they said we warranty there work. I hope it is the same problem so my cost wont go any hire. But something is very wrong, they gave me the old cam and showed me what went wrong the first time. The end of the cam has a gear and the lines are suppose to line up, but mine don't and the gear must have turned on the cam. I tried to turn it by hand it wont even move. Does any one know why this would happen and maybe even again? GW cycle said the valves are still good and they didn't hit the piston the first time, still waiting on the report for the second time.

 

[doorfx]

Did you get it hot or overheat it?

 

[crisscross1]

it over heated a year ago, and I've ridden it a lot sense. I just got off with the service manager and now he says the head is warped and that the top of the engine is not getting enough oil, but the thing I don't understand is how come there is not any wear marks on the old cam, as I still have it. He says he can't check the oil pressure because of the warp head and it don't leak. I think some one is blowing smoke up my anus. Are there any bright ideas out there because I'm out $1000 already that I can't recover.
