monoblocky goodness





from what I read they are better than yamaha, much cheaper too

 

time to get the frame to the proper angle, much easier now I have the swingarm spindle to pivot on



meant to be 23.5, but this'll do, it's more for visual than anything as all the other points will be jigged in relation to it

my adjustable support comes in handy again



Decided to shorten the base of the jig, made it long enough for all eventualities, but to be honest I need it to be more movable, there's no way I could get to both sides of it to make the frame



that's it about 3ft shorter ( chopped a little off the other end too )





this plate will tie onto the base and have fittings welded to it to secure the engine



going to make a plate up to bolt onto the exhaust studs



a second plate sits on the other side



it'll have a post like so



that'll connect to these



one in the top shock mount



the other in the linkage mount



unfortunately the lower one is a few thou too wide , need to get me to a lathe , resisted the temptation to buff it down, frame will only be as good as the jig

 

I am leaning towards leaving the bearing pockets in the neck undersize, then final boring them once the frame is 100% welded, that way I can be certain the steering stem and swingarm pivot are bob on

 

Thatsa good idea Yan.

 

I wasn't happy that the cross piece of the jig was spot on, so I loosened everything off and took the swingarm pivot pin back out. While I was putting it all back together I remembered I had a steel tube with inserts in the ends with 20mm holes, used it while putting new pivot points in the Z650 frame, so that's in the frame now ready for attaching to the jig



It has a mashup of spacers along with it, but I'll make proper ones

the lower insert was trimmed to length



and the front mounting plates started



If all goes to plan the old frame will be off tomorrow

 

Not sure what I like better here -- the bike or that build jig. Awesome work!!!

 

the old frame is off the jig, today has been a battle between me trying to get things done and my inner chimp wanting to smash the whole fuckin place ...... I fed him beer and hoped for the best .

I've been checking the specs of the new GSR compared to the GSXR, the GSXR has a rake angle of 23.5' where as the high barred GSR is 25' , the last thing I want is to go to all this grief and end up with a bike that's super twitchy and tries to launch me into the scenery at every opportunity (i'm old enough to realise I'm no super hero)....

soo I'll change the neck angle a bit , make adjustable offset yokes (letting me set the trail ) , an adjustable swingarm pivot and ride height adjuster for the shock... hopefully that'll be enough to set it up

:ttiwwop:

I'm having a cup of tea..... pics soon

 

looks like I'm done welding for the next week or so



but I was able to get to this point







I'll need to collect the throttle bodies and airbox, should have done that yesterday when I was at the shop

but since I'd got this far I had a mess about with flexi pipe

 

31st Dec.. 23:00hr...what to do ?

design frame components

that's the inserts for the adjustable swingarm pivot point drawn up , they are of course subject to change, but the basics are there, I can get 5mm up or down with these

 

it would appear I have me a headstock.... all by my own hand too



and so it begins

 

fuck yeah.

 

trial engine mounts



all will be more clear tomorrow, shed time didn't happen tonight

 

top mounts will be kinda like this



bottom



they will be sandwiched between two plates, which i can hopefully avoid looking too Martek, GIA, Spondon, IZAX

starting with paper





i'll move to mdf, then loominum

once this lot is in place (not welded ) i'll measure up and make suspension mounts

i'll be fitting a Nitron or some other posh shock

 

Same as the CB this has PAIR valves ,



so blanking these off will lose another few hoses wires etc

 

ooooooohhhhhhhhhhh


cheers Seb

 

MDF seahorses



happy daze, the pitch is right





the top bore is a midgies dick tight , but it's all good

another mess about with flexi hose



and LOOK...... just LOOK ......




it's sooo purty

 

Holy crap! I can't wait to see how this progresses!

 

I've been wanting to build a frame for years, can only imagine how excited / how much fun you must be having seeing it come together

 

stuck the T/bodies and airbox on , give me a better idea of where the tubes will have to go, top rail will be quite complex

 

It's all fun and games, till you have to make an exact opposite.

 

that's why i tell people i only like to machine one off things.. dont need to do it twice, let alone opposite.

 

asymmetric frame anyone ?

 

"Rights are a little iffy, but she goes left like nobody's business!" :LolLolLolLol:

I'm sure a man of your talent will have no issues

 

ooh , lump of loominum



look what i found inside it....... a rough cut swingarm pivot



the other ones in there too, just didn't have time to dig it out

they'll just have 20mm holes innum until the frames out the jig, then I can bore to suit the spindle

 

tidied up the machined part a bit

it'll stay pretty much like this till the frame is done





It goes here

 

and then there was two






thinking along these lines for shock mount

 

mind these?



now that I know they're the right size I can make something a bit more substantial





I can't get near enough my pillar drill to put the holes in the pair that don't take the threaded bosses, I'll do that tomorrow and smooth them off a bit more, polishing can wait until all the bits are made and ready to weld
