I was told that cannondale recommends that you should rebuild a cannondale motor. I hope this isn't because I am looking into getting a cannondale for my next quad.

 

You shouldn't go 100 hours without freshing up the engine even on your Warrior.

 

Geez, I think 100hrs is a pretty long time between rebuilds [img]i/expressions/face-icon-small-shocked.gif[/img] Knowsalot is right. I wouldn't go that long without at least putting a fresh set of rings, and a new piston in even a warrior......

 

100 hours is very little time on an engine. Take a typical weekend rider....he rides 5 hours every weekend. In 5 months he needs too rebuild his / her engine? For peak performance I can understand more frequent rebuilds. I bet one can put 1000+ hours on a Warrior before it NEEDS the engine redone.

 

100hours is reasonable for a Cannondale.

My Wolverine has never seen a rebuild with a few hundred hours I'm sure. There are warriors out there original 90 ... no rebuilds ever. Depends on the machine, maintenence, riding style, and the tech of the motor in question.

 

So how often should a cdale have a rebuilt engine? When I rebuilt the engine on my warrior, it still had the stock piston from 1996 and many other stock parts from 1996.

 

My 02 Dale has around 250 hours on it and still runs like new. I've checked the valves several times and they have never even needed adjustment.

 

100 hours at an average of 3 hours per ride .. that's 33 rides. Presuming you only rode your quad for 3 hours per week .. not much by most standards .. you'll only be able to ride for 8 months without rebuilding your motor???? C'mon guys get real... most people wouldn't rebuild their Warrior motor after 8 years .. let alone 8 months!!

 

I tell you what, how about you don't rebuild the engine every 100 hours, but put the money required to do it aside. Then, every time it builds up to about $1000 or so, you send it to me !! Sorry to be picking on ya, it's good natured, I assure you.

Seriously, any engine that won't go well over 1000-5000 hours without anything but valve sets and oil changes belongs in a Model T Ford. If the engine really needs this done every 100 hours, then I would recommend you look hard at getting something that doesn't. Like Gary and Bartlett said, a full-out race engine rebuilding makes sense, but not an every day driver.

I work on high speed diesels for a living, and they soak up some abuse that would make you cry. We still only do top overhauls every 7500 hours, or roughly 375,000 miles. For a modern 4 stroke engine, even a gas powered one, that is getting to be a normal interval.

 

He's not talking about a trail quad. A MX "day" is maybe an hour of run time if you get 2 practice runs. Still only 2 hours for a two day event. Those are HARD hours. A 100 hours between rebuilds isn't excessive, think about a drag quad.
