1260 Big Block upgrade for spanking a Harley

I can't get behind burning a motorcycle, not even a Hardly Ableson.
That said... unless he's sunk A LOT of money into his bike, you should have no problem outrunning him.

You should be ashamed of yourself! That's like clubbing a baby seal! Ed

I looked at the Night Train specs - 63 hp / 672 pounds! Maybe it should be named the choo choo train! :laugh: :laugh: :laugh: :laugh: Ed

I fully agree with Ed and Peter- your bike should hand it to him no issue right now. The Harley's have pop off the low end, but lose it quick. They're torquey, but have almost nothing up high.

I'd run him as is, and make him see what our old girls are capable of doing

These Harley guys seem to have a really distorted concept of fast. Many years ago there was a guy with a grinding shop across from the old APE building. He had a chopper with a built shovlehead. It was a barebones bike. Really nice and super light.

One day we were talking and I told him his bike was nice, but a stone stock Suzuki would just slay it in a street race. He thought I was full of it, and was eager to try. I called a customer that had a stock GS1100 ( this was in the early 80s). It had a pipe and degreed stock cams.

We went out and did the deed. It wasn't even a race. The Zuk put semi truck lengths on this Harley. Harley guy couldn't believe it. Especially when I told him he could go down to the local Suzuki dealer and buy one just like it for half what he had in the chopper.

Besides blowing him into the weeds in the straights, you can out corner him like no tomorrow. He would crash that bike trying to go around a curve, that your bike can easily take at 60+. He would be doing maybe 45 or so. Now if the contest is who is the Star in a South Park episode, well he might win. www.google.com/url?sa=t&rct=j&q=south%20...mBKAOCGXH4FmfoAuOZOA

You can do a 1260 in a stock KZ1000 block and keep the air passages. Makes a great sleeper mod, but requires some head work to take full advantage.

I am running my 1327 in a stock block which i had the air passages filled. I am running around 9 to 1 compression. So far havent had any overheating problems. But if i sat in traffic for long periods of time i could see it overheating. The only problems i have had is the bad oil leak at the base gasket :pinch:. The starter not wanting to crank the motor over very easily. I got to upgrade to a honda starter. Its tearing my starter clutch up. Both my master cyclinders now leak. But the bike is one mean son a bitch. Burn outs on demand wheelies on demand. Its got so much pull at any speed, its crazy. So far iam really happy with my build.

I'm no HD fanatic by any stretch of the imagination but I'll tell you one thing for certain. Those things respond quite well to the same performance tweaks that your KZ responds to. They'll pretty easily yield 30 HP over the stock motor. If his bike has the heads done, cams and a piston kit, you might get your ass handed to you with a tired KZ900/1000.

I've seen one go from 55HP on a Harley Shop Dyno to an honest 100 with some tweaking. I'm must stating facts so you don't underestimate and get your ass handed to you. If it's a standing start drag race, has the bike tweaked and he's sharp rider........'nough said Have a look at Drag Strip Tips thread and see what zukdave is doing to guys with his little 750 if you don't believe me.... Bottom line.....don't bring a knife to a gun fight :lol:

"A guy in town rides a stock 2000 Night Train and when I seen him at the store, he told me to burn my bike and buy a real one."



I have the 79 KZ1000st and a 2005 Yamaha Roadstar 1700.
When I hear shit talk like that from the Harley Guy's I ask them if, when they bought their Harley
did the price include 2 weeks free instruction on how to be a real f**cking Dick Head.

Usually the guys on harley's who talk all the shit are riding stock bikes. I can tell if a harley's been modded and if so I break out the ELR clone, if not I just use the KZ650.
I posted this story before here but it does show the mentality of most harley riders.

I was in a parking lot with my 82 ELR clone and was approached by a group of harley riders. One of them, around my age was commenting on my bike. We were talking about bikes in general and a really young kid, early 20's had been listening. The older guy asked me if my bike was fast. I said very fast, the young kid gave me a hard stare and said, "It's not harley fast." I asked the kid what he rode and he proudly stated a 1200 sporster. I asked the kid if he has ridden any other type of bike. He again proudly stated, "I only ride harley's." I then challenged him to a race and he quickly accepted. I told him I only race for titles, he still agreed to race me the older guy who I had been talking to stepped in and said, "No he won't."
Now the older guy knew something about bikes the younger kid knew nothing. All he had to do was look at my Kawasaki, the Kerker pipe, Mikuni RS36 carbs and the other numerous mods that are plainly visible and know it is fast. So I believe the younger generation of harley riders fall for the salesman's pitch of, "the harley davison is the fastes production V twin out there" and they believe that garbage.
Now I do believe there are modded harley's out there and I have taken on a few but even still they don't come close to beating my 31 year old Kawasaki.

A buddy has a 96 Heritage Softail 1340, it has ported heads, 10.25-1 pistons, EV-27 cam and Mikuni HSR42. Compared to what is was like stock, that thing flies. He slays my Roadstar 1700 except for loaded down 2 up riding up steep grades at highway speeds (then I can out pull him).
The KZ 1000 has Wiseco 1045cc and drop in cams. At 55 mph in top gear, he will walk away from me easy, I turn the tables on him at about 75 mph. Of course, in a drag or road race he would not stand a chance.

it is funny that baldy mentioned "harley fast" :lol: .

because around here we say there is "harley fast"and then the whole other realm of fast bikes that smoke harleys.

if anybody has any questions have them read the nhra class breakdown.

i copied it here.

Pro Stock Motorcycle:
These highly modified vehicles, which can run under seven seconds at more than 195 mph, feature a purpose-built tube chassis and a lightweight, aerodynamically enhanced replica of original bodywork. The class features a wide variety of makes, models, and engines, including V-Twin entries from Harley-Davidson and Buell and inline four-cylinder-equipped Suzuki and Kawasaki models. To ensure a level playing field, pushrod-equipped V-Twin engines are limited to 160 cubic inches, and the high-winding four-cylinder engines cannot be larger than 101 cubic inches. Fuel injection is permitted, and spec gasoline is the only fuel allowed.


this is the sentence that tells the tale:
To ensure a level playing field, pushrod-equipped V-Twin engines are limited to 160 cubic inches, and the high-winding four-cylinder engines cannot be larger than 101 cubic inches.

which should tell you that the pushrod v-twin is at a dis-advantage when compared to inline fours.
