Fz750 hybrid 1985 build

[17again]

copied from the fz forum 

New project here been sat in a garage since 2002. 

Planing on fitting thunderace running gear and engine 

should be interesting as i have never done this before on a big bike. 

played about with rd350 before. 

[17again]

here is my doner bike which i had to strip pretty quick so i didn't change my mind and keep it.

its been down the the road and it's a right off N repairable.

i wanted it because the motor had done 23000 miles






now some panels are off and sold their is no going back





i plan to use all the parts i want front + rear end and engine and sell the rest off.

[17again]

got some more of the donor bike apart today

next its the fz

[17again]

managed to get the front end of the fz today



here are the two yokes the stem swap.

[17again]

stem pressed out and fitted

[17again]

managed to dry fit some of the ace bits today.

forks

had to grind off a bit the steering lock so the forks could move right over to the left.








i put the clip ons as test on top of the yokes but still not sure about these.




engine

its just chucked in via 2 bolts went in ok.




exhaust

not sure what to do here just yet weather to try and fit a aftermarket one like a black widow (thunderace) it might give a bit more clearance.

as it hits the centre stand bracket easy to cut off i know, thinking more about the footpegs bolts

[17again]

managed to get the old swing arm oi today without my abba stand swingarm removal

kit as they are not instock.















got some top hat sleeves from steve at lucky 7 motos









managed to smash the old needle bearings out with lots of heat from my hot gun



2x TA2525Z









next i have to find someone to machine the arm and centre spacer down 5 mm per side.

[17again]

got a little bit done today.

got the swingarm back which for me i had 5mm machined off each side + the spindle 5mm by using the top hat supplied by luckymoto7

the top hats add 3mm

using this method i was able to use the dust caps on the end of the bearings still. 



fitted the new needles from bolton bearings










next ground off the centre stand brackets so the linkage would fit



the arm fitted perfectly and next i need to find a fzr 1000 exup shock as recommended David Houghton + sort out the linkage




the ace arm is a shorter see photo below but i think it will be fine as from the centre of the bolts its only 15mm shorter.

[17again]

done a bit more to the linkage today.

added the spacers at the bottom of the frame

i also had to change bush to fit the 12mm bolt which i just had one cut down from a rgv25o i had kicking around.



added some top hats spacers to reduce the frame + added top bolt to a 10mm




so far all pretty much the thunderace linkage.

[17again]

frame is back from the powder coaters now.



now the rebuild begins

Fan bloody tastic. 👍

[JonW]

Wow, what a fantastic build. Love this!

I assume the idea here is to get a faster FZ750 that handles and stops better and is a smaller bike? Im thinking that as the Thunderace frame is a more modern design and is probably stronger but is a big bike so the FZ while floppier is more fun?

[17again]

thanks for the compliments guys.

smaller but heavier lol 

yes i love the old bikes but would like the better handling as some of us do.

should go well to : )

[17again]

wheels powder coated and painted the disc up.

Do you think the rear end is to high?

dont think i am happy with the exhaust either which was bit of a cut up and reweld it job off the bike

[donkeychomp]

Brilliant! The rear end looks fine to me, but like you say that exhaust needs elevating a bit.

The rear looks fine to me but I think the front is too low.
If the plan is to have the fairing on it I'd get it loosely fitted for a better idea.
Are you racing with Yogi for 'fastest build of the year' by any chance?

[drc]

Cracking Job !!!

I love the FZ750. I had an 86 and it was one of the bikes that I always regretted selling.

Good luck with the build. I'll be following with interest

[mouse]

I don't think the rear looks too high at all, bike looks just right. But please stop posting pics, i'm so envious!

[17again]

managed to fix the exhaust and also find some nice stainless steel dog bones £20 167mm to lower by a small 5mm

[17again]

got around to putting the panels on after coming back from mark.

[matt7]

Fork extenders & above yoke clipons don't look safe.

Er not so good, she rides really well, only problem is she overheats and chucks coolant out everytime i have ridden her!!!

Hope to get her sorted soon

Sounds like the head gasket is blowing, which isn't good, hopefully it will just be a stuck thermostat, or similar
