Drag bike choice GS or KZ

[plat03busa]

I have an opportunity to purchase a KZ 1000and a GS1100 big tire set-up. Which bike is easier to build and most durable? I've heard that the KZ's will break easy on a healthy build. Input please.

Talk to dragracer on here about a kz build and I would talk to bill vose on here about the gs.Hope this helps

unless you've already got some parts or are partial to kawis........GS hands down.

[dragracer]

Plan and simple, its cheaper to build a KZ than a GS. On the other hand, you can get better performance out of a naturally aspirated GS than a KZ with comparable sized motors. A KZ has an 8 valve head and a GS has a 16 valve head- its simply a matter of flow which equates to horsepower.

I will caution you that GS parts are much harder to come by than KZ parts as far as complete motors, cases, crank etc... and the prices are outrageous in my opinion. An example- $150 for a set of stock KZ cases versus $300 plus for a set of GS cases. A used KZ crank ($200) can be checked with an index rod, welded ($100) and put straight into a drag motor. A Zuk crank ($300) will need to be disasembled, rebuilt and fitted with straight cut gears($1500) before you should even consider using it for dragracing.

I started down the path of building a Zuk to run top gas but backed away quickly when i started adding up cost versus a Kaw.

Bottom line, they both make good dragbikes. Its about what brand you prefer.

I don't know who told you a KZ breaks easily but i totally disagree. All of them will break if abused or if you run them to long without freshening one up.

i guess it depends on how fast you want to go.......if you're trying to go fast, it doesn't really matter how much a stock crank goes for.

if you want a reliable bracket bike, pick your favorite sport bike and go ride one.

Gs parts are hard to come by and those who have parts are usually not looking to sale...its up to you in the end both bikes will run the number with the right set up do you research before you go all in...what et are you trying to reach ? do u plan on all motor and a nos build

i have owned and raced both a kz and a gs in the last 30 years and it's a lot cheaper and at least in my case a lot more reliable in the long run to use a busa motor with a lite shot of nitrous.i know there are a lot of good deals out there right now on kz and gs car tire bikes but the parts are expensive and are going to run out eventually.

What they said...........................

I was in the same boat, decided on the KZ because of the availability of parts, sock and HP, and dollars spent to maintain it.

Both have been run for years, Solid platforms both of them.

After Im done with the kz,,,,,,,,,,,,,,, molly chassi with a stock bussa motor. Lock up clutch, change the oil and race for years.

GS 1100 or 1150 my choice

I'm with you on that one. My next build will be a Busa motor on an aftermarket chassis.

Between my wife and i we have 3- KZ motored dragbikes that i maintain. I've been stock piling KZ parts for a few years without having any availability problems. Lots of aftermarket parts are out there too. I've also picked up a few GS parts along the way but those parts were twice as expensive and harder to find. People will give KZ parts away but the GS parts are being hoarded by some like squirells hoard nuts in the winter time. To buy GS parts you may as well be prepared to leave an arm and a leg.

Keep this in mind, unless you intend to go faster than top gas, its been my experience that its cheaper running a KZ based motor than a GS.

I am by far a Zuk fan but haven't really saw any Gs drag bikes for sale as complete as this KZ i am looking at. The guy have the KZ at the track all the time..nice build with a solid platform. The Gs is nice 2 but not as well build as the KZ. I am looking to build a NO2 motor or something to run at least 8.50's. I just want a drag bike I can play with competetively.

If its GS vs. KZ, I would to a gs motor. Thats if you have the motor already. If you are starting with nothing I would start with a Busa motor.
