Vmax GTS project ......

Postby SBeachill » Fri Aug 08, 2014 8:54 am

Finished my Vmax a few weeks back and cut a long story short I wasn't happy with the overall finished item, built it in memory of my daughter, so the body and paint will be staying the same but the rolling gear is going to change, front is going to be GTS1000 and rear is going to be single sided too (a few will remember my old GTS project that never got finished but this one will as it's the only bike I have now so can concentrate fully on it :) )

Here was the finished item a week or so ago (which started off in October as basically a box of bits in the back of my car!):

And here's where I'm up to so far :

Started mocking some plates up out of MDF to check mounting points etc:

Will be looking for measurement info so any help gratefully received :)

IMO, the mdf plate will not be strong enough :coffee:
If a man says he will fix it, he will !
There's no need to remind him every six months about it.

Ooops almost forgot, this is why the bodywork won't be changing and why the bike will always get finished :)

The best reason ever to end a project.

Good luck. If I can be of any help once I come back home, let me know.

Steve,
Can understand the sentiments, and likewise, if you need any help, I'm not too far away, and if you want geometry, I have a spare frame in the loft, that'll give you the distance, you need...better still I can Faro Arm the measurements, so you'll have them precisely.

If it was me, start with the VMAx frame truly vertical & horizontal, locked so it can't move. Then, I'd be working for the bottom swinging arm position first, then trammel the position for the top wishbone.

You might want to move it out a little bit to quicken the steering, but an inclinometer(electronic angle finder) will be really useful for double checking the angles and making sure you have symmetry.

Good luck
Mike
I've just started riding the GTS again, and it'll be changing

Started work on the mock up plates for the top wishbone mounts and shock mount

Can't tell from the pics if those two plates are in the same plane. Using one plate or overlapping them so they share some bolts will make the structure considerably strongerr

I think it's early days yet, but if it was me, I'd use a one piece machined lump, and a reference for the existing VMax frame, as it's the alignment that is critical too.

The problem with an existing chassis is the loads are designed to be made through the headstock to swinging arm pivot, the GTS frond end concentrates the stress lower down. The good bit is that engine will take some compressive forces

As Mike said early stages yet and was debating the single plate either side possibility but was easier at first to make the two plates to see where everything locates and how it's all going to sit once mounted.

Ho, I duno if it's important, but on the GTS, the upper arm is fixed by the outside... wich is probably usefull to settle the front wheel.
If a man says he will fix it, he will !

There's no need to remind him every six months about it.

Moved the design on a little, decided to go with two large plates instead of four smaller ones. The smaller ones were a help getting things set in the right location though :)

St Jean there will be added external supports to keep the wishbone in check as I like to be belt n braces with structural stuff :)

I like that wheel!, but this rear rotor looks really big?
