Bad rep for Hyosung

[nzspokes]

Only done the conversion on the ZZR, the difference is huge. The 600 rips the 400 in half performance wise, uses less petrol and has a shite load more torque.
With the ZZR the 600 lump goes straight in (exactly the same frame) and you can even use the 400 airbox with 600 carbs.
Same tank, the differences between ZZR400 and 600 =
400 has a 180km speedo with a speed limiter. (600 speedo is 260km)
400 has smaller bore/stroke.
400 has smaller carbs.
400 has no oil cooler, but has the ability to have one.
400 has different headers (smaller ports) but the same mufflers
Different heads (even though they look the same lol)
400 has a 14T front sprocket.

Everything else is identical.
Some 600s didn't have a hazard light switch though...how trivial!

Im on the lookout for a GPZ600 motor that I will rebuild. From what ive read the motors are the same castings between the 400/600. $00 just smaller bore and stroke. 600 has bigger carbs. But in saying that my 400 motor seems strong. Going to check the valves this weekend. Would like to get one of those ape tensioners for it.

A decent tensioner is a wise investment.
Rebuilding the GPZ6 might be a bit hard, parts like valve stems/seats may not be easy to get, if at all. Always pays to check what you can find, would be a cool bike with the lighter frame
The GPZ6 had 32mm carbs I think? Not very big.
If the GPZ heads are interchangeable it may be easier for you to find a 600 crank/rods/pistons on eBay and get 600 liners pressed in to the block

If you post up pics of the block, I'll see if it's the same as the ZZR, if it is, I have a set of 400 barrels you can have for free to press the cylinder liners out and put GPZ ones in. I have a feeling the ZZR and GPZ run different blocks though

Theres a couple of motors kicking about on tm for $400ish. Apparently motorparts not that hard to get. The APE tensioners look to be $200

$200? Jebus! I paid that for my spare ZZR600
$400 for a motor is an okay deal, might be worth keeping an eye out for a complete/semi complete/crashed 600? Then pop some ZXR or ZZR rims on it for 17 inch rubber and you've got a unique and quick beast! (ZZR brakes would help that baby stop too)

WTF are you talking about? The new Kwak250 aint even an inline 4. In fact the only similarity is the name

Yes I know. I had one. Now I have something much better. WTF I was saying, was that the best you could say for Hyosung is that their top line model compares favourably with the bottom end models from other brands.... or worn out 20 year old inline fours from other brands.

They don't compare comfort and maintenance are invalid in KB arguments. Only HP and weight compare, or a loud pipe with bad jetting so it goes pippity pop pop on the overrun.

Hey, I loved the pippity pop pop the carbon pipe on my Ninja gave on overrun.
I got a lot of complements on the Ninja from non-riders. They all thought it was the nuts because everyone knows Ninja's kick ass. So far no-one has told me how sweet the Gixxer is.

I too like pippity pop I love the sound of carbs snorting and farting on the overrun.
Ahh...the good old Ninja name huh? I've had three now. Whenever someone asks what I have I'll say "just a Kawasaki ZX6"...to which they reply, "is that a Ninja???" and they're always mighty impressed and tell me how their mate has a Ninja and stuff...

Yep. Back in the late 80s, one older brother rode a TZR 250 and the other rode an RG 500. I had a pretty good idea of what each one was capable of, but I lost count of the people who boldly asserted they'd been doubled on a Ninja 250 at 240..... When I got my Ninja I soon found that it's reputation preceded it.

Was chatting to the next door neighbor, young chap. He got very excited when he learned my bike of only 100hp was a Ninja "fuck, they're so fast, best bikes out there"

I've heard some pretty choice Ninja 250 stories
