No worries, I can measure it up for you....

 

(So by fully extended do you mean front wheel in the air so no weight on the front wheel?)

Exactly.  I really appreciate it.  Feel free to email me to communicate.  My address is gard0128@msn.com.  Just put GX750 in the subject so I don't inadvertently dump it from Spam.  Thanks again.  Bernie

So what do you do when you have one bike in pieces not running - well you buy another one of course 

I'm at the point where I'm waiting on a few parts to arrive from OS for the 750 but also need funds to finish her off. Searching FB marketplace for some handy bits found me a 1982 GSX250 with the full brat tracker treatment done. Guy was selling as he'd hacked the loom to pieces & couldn't figure out how to put it back together again (I'm sure we've all been there)..... He's moving and needed it gone by Wednesday - I offered $500 and said I'd come straight around & pick it up:

How she looked pre him pulling it apart:



How I found it at his place:












Loaded up ready for the trip home:



And parked next to it's big brother:



Plan for this one is to figure out the hack job on the loom & put it all together for a quick flip to fund the completion of the 750 - I may start a build thread for this bike but I'm worried if O do I may grow attached & and want to keep both bikes......

Dillyboy, I should have added that the measurement needs to be with the forks fully extended.  Many thanks.  I'll share progress pics later.

Hey Bernie,

I forgot to reply to this sorry

The front forks are 840mm long

So not much has happened on either project this year unfortunately - work has been crazy & finances low 

I have just been able to get my hands on an '86 GSX1100ES for next to nothing. The tank is rusted out but it's complete & everything appears to be there.

Now I was adamant about keeping the 750 a 750 (as 1100 motors are just to hard to get here). But now with my hands on an 1100 motor & all the goodies to make it go it appears the 1100 upgrade is on the cards.......

Seems like forever since I've touched the bike 

I cracked the shits with the 250 as the wiring was beyond me & the cost to pay someone to do it wasn't worth the return I'd get for the bike so i bolted is all back together & sold it for $1900 - I kinda wish I'd have kept it but it was easy money which came in handy.

I've changed jobs which means I'm home earlier of a day so I now have time to focus on finally getting the 750 going. I think I have all the parts I need now so am determined to set aside at lease 2 arvo/evenings a week to focus on getting this sorted......

First thing to tackle was getting the seat sorted - i'd had the fiberglass pan made & foam tidied up but didn't want to fuck it up transferring the hardware from the old rusted pan to the new one so I outsourced this to a local auto trimmer.

She came up a treat so that's one more job done

This weekend will be getting the head off the good engine to see about freeing up the valves then hopefully take the silver engine out of the bike as well...  

I know I say this every year but hopefully I can get it done for my birthday (August) so I can get riding then start on the next project:

1979 CB750K (I know it's not a Suzuki ) then you should know better and not post a pic of it - CC

Slow as always but progress at least!!

Decided to do the quick job of moving the breather cover from the dud cam cover to the good one. Should have been a 5 min job but the last bolt went loose, loose, tight, then snap - fuck!!

Thought no worries - I'll get an easy out onto it then double fuck!!

Shelved that for later and decided to proceed with pulling the head off the black motor:

Then seeing as I was already dirty, figured I may as well pull the head of the silver motor too:

Two heads are definitely better than one!!

Except where the silver one has fucked & missing cam caps and the cams don't look too flash either:

From here I decided that seeing as the valves were proper stuck I'd just take the heads to a machinist and get them to look over both to make me a good one.

Just got the call back (Craig Thompson out at Capalaba). The black motor has nothing bent or broken - just all gummed/rusted up. It'll be $550 all up to give everything a good tidy up, new valve seals & valves ground to match, cam cover fixed & threaded as well as one of the cam cap holes thread fixed. And I'll have the silver head left untouched (still fucked but with a complete spare set of valves etc).

I think that's a pretty good price for the work involved and all going well should have it all back by the end of the week!!

 Slowly but surely she's getting there....

Finally pulled the rest of the dud motor out of the bike:

Had to grab the sump out of the dud motor as the one on the black motor had stripped drain plug threads and had already been drilled out so couldn't be re-done. She sure smelled nasty in there



The sump cleaned up a treat though (wish I'd grabbed a before photo)





I now have a reassembled engine with everything moving as it should!!!

The paint I'd put on the side covers went to shit so I thought I'd strip it and polish them up. I think the look of the black engine with alloy covers will look pretty cool -

they still need more sanding & polishing but you get the idea!!

Before:

After:

And of course polishing them up makes the previous repair stand out like dogs balls (why I painted them black in the first place).

Good old Eblag for a replacement from the states (the price was good but the postage sucks!!! It's probably what I'd have paid for something locally though so I don't mind)

The wait will suck so I'll use my patched one for now and will continue to plug away at it then replace it our once the new one arrives

And to finish it off I've bought some new badges as well (the ones I had were a mismatched pair anyway and neither were correct for the bike)
