should I keep my 2003 ltz 400 of should I trade up to a 2004 raptor 660 le I want more power and I can get a 660 for about 3000 should I keep the z or get the raptor

 

1) You are going to be giving up quite a bit of handling
2) 3K is way to much for a 660 unless it has been widened and has aftermarket suspension.
3) You can put a quality 440 kit with forged piston in and be faster than a stock 660

 

660=42hp
400z=34hp
The 660 will also have more low end torque like all big thumpers have. Even if you can mod a 400 to 42hp it will never have the torque, that come only from displacement.

Kinda like a 1300cc Harley, they may only have 70hp but they can take off from a dead stop in 3rd gear from idle but 100hp 600cc rice rocket can't.
That's torque vs hp.

 

I don't know that I'd consider trading a 10 year old quad for a 9 year old one.

If the frame mods haven't been done to the ltz by now, that would be the reason I would see to get rid of it.

 

Basically a 400z is a sport ATV with the DR400 motor in it. The 660 motor comes from the XT660 which competes with the DR650,so it is quite a upgrade.

 

thanks and scooter86 I can sell my o3 z for 2600 and im up in Canada and these quads tend to go for lots of money raptor 700s for for close to 5000 for an 07

 

I gotta ask.
Please explain what you are looking to achieve. You say you want more power but is it because you want more speed?
What are your riding conditions?

 

I would not get a 660, they have more problems than jayz has in his song "99 problems" lol. I would however get a raptor 700 though. Imo I would just keep the z, unless you can get a good deal on a 450 or 700.

 

HP isn't everything. I like the 660, but a Z is a better choice for just about anything a proper sport quad should be able to do. Jumping, sliding, slicing and dicing down a tight trail are all more enjoyable on the Zuk. There is also that pesky power to weight ratio. Stock, my little 439cc, 39hp YFZ beat mostly stock 660's in drag races repeatedly. The Z even has a few GNC MX titles under it's belt running the Yoshi 450 kits. They can be made fast. For the record, I never can get over how much more you guys in canadialand have to pay for some stuff!

 

The 01 Raptors had tranny problems, but other than that, they aren't any worse than most of the other quads out there.

A lot of times, on any machine, problems can be traced back to poor maintenance and abuse. It's easier for some to say a machine is a piece of crap than to admit they just didn't take care of it.
