Gpz 305 90% resto "Jett"
« on: Jun 08, 2011, 01:27:46 »
Here is my 90% restoration of my old racing 305. This bike is going to be for my daughter to ride.
I've been splitting time between this and my cafe 305, but this one has taken priority for now,
as my daughter is going back to college in mid August. She wants to ride it now!!! ;D

Here's what I started with:






Some of the teardown










Can you say, "screw extractor" >:(


The resto taking over the cafes' place of honor on the lift




Frame/swingarm painted/new tires





It won't be a complete resto, as it will have a Yosh pipe and won't have the stock decals. I tried to find
decals and can't find any gpz 305 ones and the 550 decals are about $200 and I don't think any of
them would fit anyway.

Hope to have it finished in 2 weeks

The GPz is one of the bikes of my past & holds a special place in my childhood thoughts.
 
A friend of mine owned one back in the day and I used to scoot around on it.
 
Here's a pic of me sitting on it way back in '85:
I know where I can get one right now, may jump on it, not sure....need to straighten out other stuff before I take on another project.
I may be paralyzed...but I can still kick your butt!

They're fun bikes to throw around, if you get a chance check out my 305 Cafe build, just link to it in my signature below.

And if you decide you don't want the one you know about, and it's not too far away from me, let me know, I would
be interested in it.


Thanks

I checked out your cafe' build a few days ago...I'll keep watching the progress.
 
The bike is in Maine a couple miles from me.  They are asking a bit too much, but it's all there and a runner.

My first bike was a GPz 550. Loved that thing. Good luck with the resto!  ;D

Finally getting something done on the Gpz. The engine is rebuilt and installed, finishing up the carbs and detailing and priming the bodywork. I want to get it running and then I'll paint the engine after a test ride. That way I can check for any leaks before painting.

Got the wiring mostly done last night and today, just trial fitting the body work making sure all the wiring is where it supposed to be. Hope to have the carbs done in a few days, and take it out for a ride to make sure everything is working right. Then it'll be time to finish painting and detailing.

Carbs rebuilt and installed



New grips, wiring done, clutch cable and lever, brake nearly finished.



Yosh 2 into 1 installed.



Got her started and just need to adjust the carbs a bit, much quieter since I
repacked the Yosh. Didn't realize how loud it was until I got it repacked :-[

Well tried starting it up Thursday, would run on full choke on one cylinder and sometimes fire on the second. At first thought it was a bad coil, changed that out and really didn't make a difference. I'm sure some of you already know where this story is going ;)

Went back and cleaned off the new paint at the coil mounting points and cleaned all
the connections again, cleaned the paint more at the ground wire, and guess what....
yea it runs fine now! :)

Moral of the story. Remember what you've been told over and over and over, make sure you have a good ground, before you over think the problem and do a lot of extra
work. >:(
