07 Iq 600 Cfi

Check the oil pump yourself. Dealers have a tendancy to not care if they did service properly.

And the most important thing is to actaully check your oil pump. Mine was checked as per the service bulletin. I got it back to my house and checked the sync myself to be sure it was right, and it was. 1000 miles later it wasnt burning much oil at all. So I decided to check the sync again. And what do you know... The oil pump wasnt opening until about 3/4 throttle.

And even worse, I decided to check and be sure the oil pump was set at the the proper adjustment for cable slack or idle alignment. Sure enough. The cable was completely slack... And the oil pump arm was being stopped my the motor mount it was so out of adjusment.

Somthing definatly made it past the quality control dept on these sleds, but I can almost assure you that this was your problem.

I highly recomend that everyone check the oil system themselves on every sled they ever buy. It doesnt make sense to rely on your dealer to do the work. Do it yourslef any you will get quality in return.

I hope everyone at least read what I said above about the 600 cfi oil system being way off.

I have already heard of 3 600 cfi motors blown.

Also where are you getting the rpm's from, if your looking at the peak RPM's reached in the computer, that is not the info your looking for. If your sitting at a stop and slam down the throttle its going to jump over the 8200 mark until the clutch shifts out, which should be very quickly. If your at full throttle and have been holding it there for a while and it still says 8600 on the tach (dont use the digital gauges for the rpm's, only the analog for the best reading) then you are way to high. At full throttle across a lake mine only does about 7900 rpm's or so, and that is at about 96 MPH. But if I were trying to drag race and mash down the throttle it will jump to roughly 8600 RPM's for a second, which is not usually bad, its only the sustained high rpm that you should really worry about.

This problem is very very unlikely the culprit of the burned down motor, but HIGHLY likely from the lack of proper oil setting from the factory.

I realize the RPM is just a peak...on top end 95MPH or so I noticed a digital reading in the range of 8150-8200. I never really checked it on the analog. As for the oil pump issue... I kept crying foul at two different dealers for two weeks and they completely ignored me and told me to keep riding. I guess I have their attention now. I made a few calls today and got the General Manager of the dealership on it. The machine was being stripped down late today....I should know the problem in the morning. I'll keep everyone posted. Thanks for the info.[/b]

Thats exactly it though, the top speed rpm is right where it should be. If your just looking at the top rmp memory function your not actually seeing the important detail. Sustained speed at anything over 8400 could very likely cause engine damage, but please note that the damage to high of rpms would cause is much more likely to be in the crank bearings that the pistons and cyls.

If you burned down a cyl then it is the cause of to little oil or improper air/fuel ratio. And if I could shake your hand I would actually bet a new motor on the fact that you werent getting enough oil becuase these things are way out of adjustment from the factory. Burning 1 gallon of oil to 1000 miles like I did is absolutely unacceptable, granted the true factor is how much gas I burned during that 1 gallon of oil, but it was way to little.

I am actually leaving on friday to take about a 600 mile in 3 day trip, so hopefully my new adjustments to the oil pump will actually prove to work properly. I am looking to burn about 1 qt of oil every 100-150 miles to start, instead of 1 qt every 250 miles. Then I will start to adjust to get the proper 50:1 or so. Granted in these new injected sleds your not going for a perfect 50:1 ratio. Maybe we should just run pre-mix. Unfortunatly for me that wont work because I take long tips like I will be this weekend and need to have an oil injected sled. So finding an acceptable oil injection ratio is critical.

So this weekend I will be around 1800 miles and crossing my fingers plus knocking on wood that this thing isnt going to follow the fate of other 600 CFI's so far.
