We all have heard about the dales "pukin" oil in the air box and filter, but no one really knows why. I talked with a Cannondale Rep. two days ago (Justin Ostrich I think his name was) and he said that he was aware of the problem and that they did have a problem with some banjo bolts that only had one hole in them rather than two which cause uncontrolable oil pressure and it had to go somewhere. The other problem he said was that the consumers were just puuting too much oil in their engines. Now, Kyle at R&S says that he runs only 1/3 full in his bikes and that seems to be working well for him but there was still no expanation to the problem. What is going on here?? Kyle also said that he hadn't heard of the whole "banjo bolt" senario. Could someone please give us some insight to this matter. Perhaps Knowsalot could live up to his name here? Thanks, Jared

 

read the cannondale rep thread.

 

It's KNOWSALOT...not KNOWITALL...LOL

I am just as baffled as the most the other guys here concerning this matter.

I have seen it once and it was on a Cannibal that a guy crashed [at the drag strip of all places]. We cleaned the mess, refilled with oil and it hasn't been back since.

Every bike and quad that has left our dealership has not had any oiling problems that I am aware of and as far as I know, all of them fill their oil to the line on the dipstick. I know that I do, and haven't had a problem.

The banjo bolt scenario that has been brought up would be a solution to the mystery, but I never heard of such a problem until I read it here yesterday.

Until Cannondale tells me to lower the oil level....or until Cannondale tells me there is a banjo bolt problem on some models...I will continue to recommend what Cannondale recommends.

 

What the hell is a banjo bolt? Sorry for going off topic, I just wanted to know since I had never heard that term before until yesterday.

 

When I told Kyle about the oil puking he told me it might be from the oil expanding in the engine. Thats why they run synthetic. He told me to run half to the line. this Problem happened once. But it was when i beat the sh*t out of it. Has happened since and it baffles me too.

 

Itracer,

I banjo bolt is a bolt wtihthe center up to the head drilled out and than a hole though to make a T. It is than placed into a banjo fitting and the fluid will be pumped up the center of the bolt into the ring and up into the hose. Look at your oil drain out of the motor.

ALL,

The problem with the oil is a piston, Ring, and something else problem. It happens on earlier motors, like mine and is being taken care of.

Call Cannondale if this happens to you and talk to Andy.

Thanks

I bought mine in March 29,2002. Its not an earlier model. The oil puked in mine. So could my piston, ring. too

 

Thanks for clearing that up smitty. I think Scott Montgomery needs to step in and clear up what exactly is causing this.

 

MXRACER,

Just because you bought it in XXX doesn't mean it wasn't built in YYY. There is a series of motors that had this problem and Cannondale has the number of those motors. They will be able to tell you if your motor is part of this series and help you get the problem fixed. It does only happen when you are running HIGH RPMS for extended times like racing. If you haven't seen this yet your probably not effected.

Since there appears to be a series of engine serial numbers that are affected, you would think they would post this info on their web site for a recall or tech bulletin or something. I think all of us who have not had this problem and may have motors that fall within this so called series of serial numbers should know if our's may be suspect or not.
