GZ250 from a different perspective

Flathead · 01-16-2017, 06:24 PM

Flathead here. This is a GZ250 I built recently. Enjoy the Madness. 2013 GW250 rear shock, 1970 TU250 tank, 2006 EX500 fenders & a lot of Flathead ingenuity. From Crusty to cool.

Very innovative design. I especially like the mono-shock setup. It's just not for this skinny old butt. I need lots of padding these days.

WOW! That is quite a transformation. Very well done.

One thing I have to know. Did you extend the swing arm? It sure gives the bike a longer look with much of the bits and pieces removed. Do you think the bike weighs less now?

The seating is for a marathon runners body. Kind of hard on this older body. With that said I am 6' & 180 lbs. I have personally put over 1000 miles on it during testing and proof rides & it is an absolute blast to ride.
The swing arm is stock length. The GZ250 swing arm is about 7 inches longer than my KZ440 swingarm which makes it perfect for the shock. The GW250 has the same swing arm & monoshock but would not have located the shock in the area I wanted it so I mixed the two Suzuki models. The bike weighs about 200 lbs. Maybe less.
The bike is so versatile. The GN250 has been modded for years but the GZ250 has been overlooked. Thanks

Shedding 100lbs. from the bike is quite a drastic change. I'm sure it gives the bike a lot of extra zip. Nice.

How does it run with after you relocated carb? Nice setup.

The bike ran great for about a month. Then I was caught in a rainstorm. The filter location caused her to drown. I have relocated carb to oem position but with a slight Flathead twist. There is not much real estate between shock & rear of engine. I will get some new photos of updates I have done recently to her.
The bike is very responsive. Great throttle response. I will update the carb size at some point for the owner. It pulls hard thru all gears & sounds like a mad bee. Quite the head turner. People that see it on the road want to know what it is. It does travel the interstate a lot. Top speed so far is 74 mph.
Have any of you spotted the battery yet? It does have an oem battery on board.

The bike has a completely new wiring harness. The wiring for a GZ250 is the same as a chinese scooter. Horrible, No joke.
The ground wire strands turn real dark. The charging system can back feed into the harness keeping it from dying with key or os switch then fails all together.
This bike has a Kawasaki charging system that disconnects ground to kill bike with key. The os switch on rh bar disconnects the cdi ground.The headlight is blinding brighter than oem. There is a led flash light for a brake light. It still says eveready on the side of it. Thanks for questions & allowing me to show her off.

Is that the battery underneath the mono shock?

Flathead here. It is under the swing arm pivot bolt. Nestled up behind the rear of engine. You can see it in the 3rd picture.
