Cagiva Mito 350 YPVS Project

[paul8899]

Hello,
  Great site,loads of info. I saw this thread about project bikes and thought I'd put mine up to see what you think.
I got my inspiration for this bike when I saw tha yagiva bike (its on google) and thought that it looked good and thought I would have a go at making one for myself ( but a bit different from the norm)

Heres how it started off, just a bare cagiva mito frame



then I decided on this swingarm, its from an 09 R6 (almost the same length as a standard mito arm)



I then came across the first (of many) problems when building a bike from scratch. The shock mount on the mito is offset and the r6 arm has a big hole where the shock usually goes and the 2 wouldn't fit.
I had 3 choices,
1 : fit a monoshock directly from the frame to the swingarm (not very technical)
2:  fit a rising rate system by making some mounts for the shock (keeps the r6 set up but has been done before)
3 : make a system so the shock linkage etc is enclosed on the swingarm and is only connected to the frame by a tie bar, a bit like the one on the fireblade (well, a lot like it really )

So I decided on option 3, the only problem is that there isn't anywhere to mount the tie bar on the bottom of the bike so I decided to turn it over. I made these mounts up , I just have to get them welded on and make a linkage up




and here they are glued onto the arm just to make sure they fit



The next thing I had to get was a set of forks,wheels and brakes. So I got a bit carried away and got a set of forks off a 05 zx10r and the wheels and calipers are off an 09 zx10r. Nice radial brakes and a 190 rear tyre

I then had to cut the width of the swingarm down to suit the mito frame and make up some new bearing cups to suit the smaller diameter spindle. Then once that was fitted in place I made up some temporary spindles and some rear wheel spacers and it looked like this



I had a bit of spare time at work and got to thinking that theres nothing to hold the forks in place so I made these up





And here it is with the engine in place



Theres still a few jobs left to do, I think the hardest bit will be getting the rear suspension to work properly , the rest "should" be easy to do

hope you like it

Cool project    and welcome

looking forward to seeing the progress on this one

[warmseth]

Whoa. this is gonna be good.

[Kraven Morehead]

WOW!  I will be glued to this thread!! 

[nojibski]

this is gonna be the super, cant wait to see more!

i see a bike of the year in the making easy.
wow.  nice cnc work.

No shit.  You better start making RD parts for the rest of us .  4king drooling over here.

i 2nd that for bike of the year.   Can you imagine CNC heads for the RD?  That would be ultra-wicked.

Looks like I'll have to get my finger out and finish it then , if I'm lucky I'll have it done by christmas and if I'm really really lucky it will be 2010

I was thinking of making a cylinder head out of makrolon ( a high spec lexan ) , I've checked the melting point and it "shouldn't" melt . Have to wait and see

We use a Markolon at work, if it is the same stuff that you looked up I don't think that it will hold up to the temps.  It doesn't take much from the heat gun to bend it.  Melting point and the point to where it starts to get soft maybe 2 different things.

Sweet project that you have going on though.

[paul8899]

I'll have to have a closer look at the specs, The spec sheet I read said it starts to melt at 220-230c and it starts to go soft at 115-130c so its a bit close temp wise. Not sure if it would take the pressure from the pistons, would look really good though !

I might give it a try when I finish the ever growing list of things I need to do to get it finished , if not out of lexan I might just make a boring ally one

Thats probably the same stuff, I am sure the heat gun gets it to 115c no problem.  You also have to watch with it, if you torque down on it to much it will start to spider crack.  I wouldn't be suprised if it cracked out by the head bolts.  Another thing to remember, it the aluminum is taking a lot of heat away. You would have to look into how fast the Markolon can shead the heat.  It would look cool with a seat of heads made out of it, even if it was just for a short vid of it running.

use replacable ally domes and markolon for the body of the head. at least oyu can watch the coolnat moving.  thats way cool. uber-bling

I thought about the heat ransfer, I was going to make the coolant gap a bit bigger than standard and have the top of the head thicker so the ally insert doesn't pop off.
What about having some steel inserts for the head bolts to bolt down on?
I wonder how hot the outside of an engine gets ?

[Premiumjo]

Welcome!! I dont know why you bought wheels and forks, It looks like you could've just milled yourself a set
Nice job so far. Cant wait to see the progress
(Maybe if you ask nice, sakeboy will donate his trinity racing motor to the cause!)
