Time to start a new project, This one is something I had in mind when I finished my first build but because of time/money it didn't start. This is going to be a long termer but hopefully it should be finished by the end of the year as there is a lot of work to do and hopefully it should help spread the cost of the hardware.
The name should give away the concept of the build, basically I have a couple of old minimotos that I can't run on track anymore (noise restrictions) and so I thought it'd be a cracking idea to utilise one for a build.
Ok some pics of where it's at
The bikes have been stored under a table in one of my sheds, it will give you an idea of how small these little motorbikes are.
A bit of a zoom shot, you can make out some old bodywork there too, this body work might still be used but I figure that i'll have to make some new bodywork or at least add acrylic windows and modify these ones.
Here it is next to my road bike.
So now the bike has been rescued from a life in a garden shed, this is what it looks like in isolation. The reason I have chosen this one is that it has a very nice trellis frame with plenty of points to mount the hardware.
Ok so now it's time to remove the engine, don't worry it won't go to waste, I have another frame that it can go into.
The bike without the engine, there's plenty of space for what I have in mind. I will keep the throttle and brakes, It will need brakes to help it stop....err yes you did read that right, I plan to put an electric motor in the bike so that it will still run and i'll still be able to ride it. (it'll raise a few eyebrows at Lan parties)
A view from the front, the PSU to run the PC and battery for the electric motor will fit under the seat. It'd be good to figure out a way of running the PC and the electric motor off the battery but failing that it will run off two different circuits.
I have made out a board that is the same size as a mini ITX board to give me an idea of how the mobo will be mounted
The system will be water cooled, I test fitted a rad, which is just a little too big so I will have to use smaller items. The reservoir will be in the obvious place, the petrol tank (gasoline for our American friends :eyebrow: ) There will be two rads mounted inside the frame on both sides of the bike.
So hang on tight and watch where this project goes, you should be able to guess what direction I'm going in with the coolant

Here is some different renders with LEDs and tube fittings.
On the last update I mentioned that I was working on the seat support, I have had to raise the seat by about an inch to accommodate the battery under the speed hump, but the upshot is that it's given me more room under the seat to fit the other battery and more room under the tank for "bits" too
To raise the seat I have used some old handle bar risers from another bike, they have been chopped in half, drilled and tapped. The supports are made from aluminium bar and again chopped to length,drilled and tapped. The bolts have been cut to length so I don't have unsightly threads sticking out from the frame.
Fitted to the frame, it is really sturdy and I will be able to sit on the bike without the body work cracking.
View from underneath the seat unit, The seat bolts directly onto the supports.
With the seat supports fitted, I can now locate the second battery tray, yes with new cutting discs I got round to making the second one.
I looked at the old case that had been chopped up and decided to use the rolled edge that the panel latches onto, this will maintain the angle of the top of the frame, it also adds some rigidity to the support and will stop it sagging under the weight of the battery.
I have riveted the brace to the battery tray, it's temporary fix, and will be disassembled for finish and paint (the parts list is growing rapidly for finish and paint) the rivets are nice and flat and won't interfere with how the battery sits.
Finally both batteries in place, you'll notice that the front seat support will make a rather handy retainer for the battery, the rear battery will need a strap to hold it in place.
With the batteries and the motor now fitted, I will now look to fit the motor control unit, get it wired up and do a test ride...:D
just tying up some loose ends on stuff that's been done and not added to the log.
First off is the radiator, I've gone with a small 160mm Rad. This gives me more options on mounting hardware, This is fitted with some simple brackets cut out with the dremel and screwed directly onto the frame
The rad now sits inside the frame and gives me more room to mount the motherboard tray, I'm going to angle it so that it follows the line of the frame. The previous idea of mounting it flat kinda dragged the whole bike down and I wasn't completely happy with it, so now it looks something like this
That bottom engine mounting plate can now be chopped off, it was the one thing about the frame I really didn't like as it was just poorly finished and a bit of an eye sore.
I have made up a rear seat pad this is just for show and will be upholstered to match the seat, I have changed my mind on the colour and have some new material but that's for another update.
I have fitted the ignition barrel, I went with this option because if I had just gone with a kill switch I could imagine the first thing people are going to do when they first see the bike is twist the throttle and the bike will be off the table .... so key needed I think.
Nothing too difficult just a hole with a slot to stop the assembly spinning when the key is turned. It does give it a nice feel to be able to turn on the bike with a key.
Next up is the PSU, I had this rather nice unit from Silverstone delivered today.
It's a nice little unit and should supply all the power I need, with it being so small I can fit it exactly where I want it and the brackets shouldn't be to hard to figure out.
There's a few cables so be sleeved but i already have some sleeving, but that's for later. This pic should give you some idea at just how small this PSU is
It's going to fit into this space here, I do need to remove a few of the tubes either side, but it will allow me to run some of the cables through the frame.
That's all for now... apart from the where it's at pic :cooldude:
(the vid I promised will be posted tomorrow)

Just started cutting the res for Mini Moto Mayhem mod, here are some of the photos from this evening.
Thats one side done, will turn it over to do the Mayhem logo and cut the shape to fit the body of the mini moto shell.

Now that I'm happy with the bodywork fitting, I can now look at prepping for paint. The first thing is to get rid of that nasty race number, not so easy as it is lacquered in. So it's out with the sander.
The sander makes short work getting rid of old paint and lacquer.
Back down to plastic without hardly any effort, A quick sanding by hand and it's nearly ready for primer.
That sander really cuts through the old paint.
So I thought bugger it and done the whole lot.
It wasn't without it's problems though, I found a nasty lil crack on the seat unit.
So I'll mix up some Araldite and reinforce the back, it's drying as I'm updating so I will let you know how it went.

with the bodywork now fitted I can now look at fitting the motherboard tray and shape the belly pan.
I'd already marked where i wanted to cut, to maintain the shape of the fairing and expose enough of the Motherboard as I want people to be able to see the guts of the PC. I will be using ASUS's new Rog Itx board and really want it on display (as soon as it gets to market)
so enough waffling here's a reminder of the area to be chopped
The motherboard tray is now fitted and secured, you'll notice that I have changed the IO shield. This is to allow another fixing point to the frame and to stop it wobbling around when the bike is being ridden. It also has the benefit of providing some protection from stuff flinging off the front wheel.
A view through the front forks gives a better idea of the protection that the grill will give
Another view from the front, shows the shape of the tray and the cut out of the belly pan
Finally a view from the side, you can see the final shape of the belly pan and how much of the Motherboard will be on show.
There's still a few minor shaping details to sort out, but the belly pan and front fairing are nearly ready to prep for paint (this is when the build will start to shine)

Started work on the top cut for the res this evening, here are the snaps. 🙂
After the final cut, I started to hit it with wet 'n' dry.. Sadly I got peckish and thats as far as I got..
I still need to face the sides and add holes for LED's and M6 mounting holes.
Will take a few hours to polish this bad boy to a blinding shine.. Im sure it will be worth it in the long run

So now I'm now looking at starting some of the paint work, Luckily I have a family member that is a professional paint sprayer and he's agreed to help with the paint. I was originally going to get this airbrushed but the cost is ridiculous for what I want.
With all the sanding done it was time to fill any unwanted holes and stuff i didn't like. I used a flexible plastics filler it doesn't have a very long working time and had to do this in three batches, yes it sets that quick.
It's applied the same way as any other filler
and sands down really well
I made a makeshift spray booth in the shed. This is ample for laying down some primer and the final coats will be done in the family members booth.
The panels were wet sanded between coats
wiped down with white spirit and tack cloth.
After 3 coats, I applied some satin black onto the belly pan, The satin paint is very easy to get a good finish with. The gloss coats for the other panels will be done by the professional sprayer.
The logos will be applied and lacquered in and that is the belly pan complete
