shocking trouble!



The front end is on with a longer steering stem, cut, sleaved and welded. The lock stops have been modified as they missed each other completely. The fork internals will be a case of wait and see but we think they may just do the job, at least for now.We are confident the front geometry is ok at this stage.

The rear thew up a few head scratchers. The swingarm goes in with a little messing with differant shims and spindles worked out by Phil.

The swing arm top rails were banging on the subframe, so this will be removed and a lighter alloy used.

The next problem is the shock. In order to keep the correct alighnment of the swingarm and shock, we have worked out that we will need to weld a new top shock mount and trim out around the hole in the swingarm where the shock routes. there's not a lot of room for a bottle so we will likely need a remote bottle.

Wheel alighnment and chain run both look good.....so not too shocking......untill it's time to fork out for a new shock.
THE SUB FRAME GETS IT!
I have been itching to cut it off!
Stuff in general is getting a polish and some paint here and there while we wait for santa to f*** off and then things will get going soon after that

Hi, can I ask how u fitted the new forks? I am doing a FZ 750 streetfighter and want to fit the same forks. Did the rear swing arm go on problem free (ish)? cheers, Andy

In order to fit the forks, the steering stem had to be lengthened. You would do better to fit a R6 front end, (98-01) , much better turn in, better brakes and better forks. This is something I would like to do over the winter.
the rear is fine in the performance but had to chop off and weld on new bracket to take the shock. This has to be repositioned towards the engine further than standard and also higher if I remember correctly. also the chain is reduced to a 520 to improve alignment. 2mm is machined out of the back of the rear sprocket where each bolt goes onto the sprocket carrier, so the sprocket sits closer to the wheel. the front sprocket is packed out away from the engine, this leaves the locking washer right on the outside limit and makes fitting the sprocket nut a bit fiddly.
the swingarm goes in with just a 2mm spacer on the brake side.

best of luck.... I had a ball doing mine

if I can help further, I would be pleased to.

Brilliant, thanks...How would I o about lengthening it? Is it a big job , and do you have any more pics? Thanks so much for your help! Andy

The steering stem was modified by a friend of mine.
He cut it in half and welded in a new section to get the required length.
A relatively small job.
here is my direct e-mail:

I don't have any pics of the process or even of the finished article I am afraid.

I would still reccomend an R6 front end as it is a straight swap with no messing but if you already have a YZF front end then go for it!

hey, i own an 85 FZ750 and looking at changing the forks and swingarm. i've been offered a 89 FZR1000 rolling chassis for a decent price, and was wondering if the forks and swingarm off it would fit on my bike? have looked around and haven't been able to find any info. any help would be greatly appreciated. :-)

kind regards,
