During a race last week I landed real hard (over shot a double & flat landed) the bike stall instantly & did not want to start again! I finally got it started and now it runs rough. It pops and farts won't hold an idol. I can forget about hole shots, it just stalls. It also makes a grinding sound enen in neutral with the clutch pulled in. I changed the oil right away, no shavings. checked valve clearance it's within spec, pulled all wire plugs and cleaned with contact cleaner.
I have rode lightelly around the yard for about 2 hours and checked oil again, still clean!?!?!? I don't want the dealer to work on it, they are backed up like 5 weeks.
I landed hard enough to crack my frame in 3 places on the FRONT END!!!(more on this with pics in another topic to follow)
I'm wondering if it isn't in the overturn kill switch,or the EFI/ throttle body, the bike took a hard shock on this landing(falling 8 feet onto flat ground in 3rd gear 1/2 throttle) as did I. Any direction on approaching this issue would be greatley appreciated.

First off welcome to the site!

My first guess may be to check the throttle body boot to make sure that it didnt slide off a little bit. You can check the easy way by spraying carb cleaner on the boot(while the bike is running) and if the idle goes up at ALL then you have a a leak. The carb cleaner is flammable so if it get in any leaks it will make the bike idle higher.

My next suggestion would be to take the tip over switch off and silicone it so that just in case you decide to over jump anymore jumps it won't stall from that(eliminating some options)

Next, I have heard of a few Crank Position sensors getting crudy and making the bike run like crap, so check that if you already havent.

Well, until you try them get back to me and I will try and help you out as best of my ability.

Be sure not to forget about those pics of your cracked frame!!!!!! Good luck, Nick.

Sounds like maybe a loose wire or cut wire. If you landed that hard, surely some of those plastic plugs got shook loose. Dang cracked frame in 3 places, sounds like you got more problems than just the engine.

I would have to agree that you probably have an electrical issue some where. My only concern however is the grinding sound that your speaking of. Can you elaborate on what this sound is.

Well i dont know about the grinding sound but the running rough bit sounds exactly like mine. It has taken over 3 months to resolve this so far. Up to now, all sensors and ecu have been replaced with no fix. We have a complete wiring harness on its way from Japan because now it can only be a broken wire or connection, nothing was found on numerous visual inspections so mabye there is a weak link in the loom somewhere. The other thing that helps my thoughts on this is i had done a half dozen jumps when mine failed and it was pretty much an instant stall. After that the popin and fartin started.

I expect my loom to get in next week and I know Suzuki Australia will be stripping the old loom to find the fault (simply because of how much it has cost so far) They are going to keep me posted when they find the fault.

Will keep you posted

Just got off the phone to my mate fixing my bike. Ok the guy is a bloody genious when it comes to this stuff. He is interested in the crank sensor which is what i am assuming is the little weight looking things on the flywheel (I have not seen them myself on this bike). He seems to think that this or one of these have come off.
So when you crank it, the ecu ignites the spark plug twice and then the ecu should get its readings from these sensors to get its information. Therefore if it isnt there no go bro!
Has anyone had a problem of this sort with this sensor, is it possible for this to happen? I have not looked this far into the bike and dont know myself?

And Junk, every time I see a bloody live rooI dont have my camera. It is nearly at a point where I will lean a dead one against a tree, chuck a stick in its gob and make it look like it is still breathin.

Uhh...no...thats ok...I'll pass on that one thanks...I really don't want to explain to my kids why there is a stick up a Roos "gob"...

I can only imagine what a "gob" is... :p

Hot, there is a pretty in depth system of light flashes...the way your FI light blinks will tell you what the bike is thinking...

The code for CPS is a 12. That means there is a:

0.3 second light = 1

1.0 second off

0.3 second lights =2

3.0 seconds off...repeat signal pattern

If you don't have a manual let me know and I'll burn one off for you :D

I've only noticed a flash code on the FI light once, abd that was the other night on my practice track, but by the time I made it in to write it down it stopped. I would think if it were a crank sensor, it would happen all of the time. Also I don't have the shop manual yet, but deff. want one if you can help me out.

I should have the pics of were the frame cracked posted by Monday.

I heard that from a few guys from the racing circuit. They either cleaned the sensor or replaced it becasue the bike was either hard to or wouldnt start.

All of the replies have been great, let's keep them coming. As soon as I get the manual I will be pulling it apart. I will let all of you know what I find AND THEN I WILL CLOSE THE THREAD. We all want to know the final solution and I will be following up with all findings.

I will be checking this post at least twice a day.

Thanks, to all of you.

P.S. I own one of those faster White one's, White is easy to keep clean when you're out front!!!....LOL... B)

I dont have the bike here, it is in the hands of Suzuki back where I bought it from. Its a bit of a laugh the ended up calling my mate in to have a look at it. Anyway I will be getting an answer on Monday if its the flywheel pulse sensor or not.

The "Gob" is its mouth. They eat leaves and branches and shit. (Not "shit", bushes and stuff)

Hey guys, I know I'm fairly new, and we all appreciate humor, but can we please keep this thread to the point, there are problems that need to be addressed. I like to laugh, but I'm finding it a bit tough at this point.
I think it would help all of us if there was less B.S. to scroll though to get resolution. I know people like to have fun, but I would like to keep it simple stupid. I respect this forum, but I thought we could be serious once in a while.
I trully need help. I'm in the midst of opening a small fab shop that will benifit us all ( I'm not looking to get rich, just support our sport) I will be a premium member by Tues. and have some new stuff to offer at a trully fair price, lets help each other out and maintain some easy to follow threads for us and people in the future.

I hope I'm not out of line on this request. If I am please PM me.
thanks.

What was with the grinding sound? I havent seen you say anything more about it. It could possibly be that the crank sensor cam out of the bracket and is rubbing on the flywheel. You could remove the stator cover on the quad and check this yourself.

I haven't had the time to open it up. Hopefully 2 night I will get the chance.

Well I removed both side covers to see whatever I could see. spottless! no shavings, no chunks. I hope the grinding isn't in the tranny! I cleaned the crank position sensor as well. We a real bad storm roll through, so I haven't gotten to ride it yet to see if it runs better, more to follow soon.

well since there was a month of warranty left, I put the pee shooter back in, the lid back on, & the cherry bomb off. Still ran like crap and had a grind inside. Dealer bound it was. Bad EFI chip, & counter shaft, don't know all the details yet, just keeping everyone informed!!!
