Thats not bad

Well I got to play a little today in the neighborhood. I originally had the sprockets setup backwards where I was only getting about a 1:1 ratio. Thats why in the video it took a lot for it to take off. I swapped the sprockets giving it about a 7:1 ratio and it was WAY too high. I had to take off in 2nd or 3rd and the top speed was pathetic. It could however pull stumps lol. I swapped out 1 of the 13t sprockets for a 16t which gave me about a 5:1 ratio. Much better. This thing is crazy fast lol. It's still geared high but I won't change anything until I get it into the dirt to see how it is.
It was fun banging through the gears in a cart. The hydraulic clutch works perfectly. Now i have to modify my little 4x8 trailer so I can actually fit this on it.

Sounds like you had fun!! Just for your information, the higher the number of your gearing, the lower you are geared. The lower the number, the higher the gearing.

You are absolutely correct. I always get those mixed up. Who knows when I'll be able to get it to the dirt, the wife has a huge honey do list for me since i've pretty much dedicated every weekend to this project

I love this thing. I really need some dirt now.

sorry, i know you did it ages ago now but i see you used a cbr 600 for your buggy. how hard iis it to wire in? did you need to buy a wiring loom and connect everything up? please help as i am planning on getting a cbr but dont want to have to use the whole bike's loom and computer. cheers

If I may-
You're better off starting with the original wiring harness, and then just deleting the circuits you don't need.

As Toy stated, I also used the entire wiring harness with computer and relays. I just made a nice mount behind the seat for everything.
Been working on reverse for it. Welded a sprocket on a starter motor and made the brackets. Just have to do the final welding and hopefully it will be good to go. I still have to figure out how to wire it so that it will only be able to activate reverse when the motor is in neutral. That way I won't blow up my chans lol.

That should be pretty easy if your donor machine had a neutral indicator light. Take the lead from that circuit, and use it to trigger a high-current solenoid. In the same circuit, install a pushbutton (or whatever actuation method you had in mind). This way, tranny must be in neutral AND you pushing the button, in order for reverse to engage. One or the other will not do it.
If the starter you are using has a built-in solenoid, then you just need to run a light-gauge wire from your neutral light, thru a button, to the "start" terminal on the starter- this is the terminal that would normally be energized by the start position on the key.
And- how do you propose to eliminate the problem of the chain constantly spinning the starter- will you have a way to disengage it?

The starter i'm using free spins backwards until engaged. Thats a good idea about the neutral light. Should be real easy, thanks for that.

Well that wiring won't work. The light has a common +12v and when in neutral, a ground is applied.

No probs- that's why God created relays!!! Get yourself a standard 4 or 5 pin, 12v automotive relay, and-
Feed the light's switched (-) thru your pushbutton switch to terminal #85 on the relay. Run a (+) lead from the battery to terminal #86. Jump another (+) lead from terminal #86 to terminal #87. Finally, run a lead from terminal #30 to the start terminal on the starter solenoid.
There may be another way to pull that off, but that's the way I would do it, if I had it sitting in front of me right now.

Be careful some relays can't be wired backward like that
So 30 and 87 is the high current circuit
30 gets + from the battery and 87 goes to the starter
85 and 86 is the activation side
85 takes + from where ever
And 86 grounds out though a push button
To add a safety switch in u would have to run the ground though the neutral switch running it in parralel
So find the wire running into the switch and T the relay earth in
U want the light to be totally independent of reverse
If u wire it in series then the light will only work when u are in reverse

TBH if you are willing to be patience and willing to learn, its not overly hard. I had a gp750. It had no wiring with it, I just found a diagram and made my own. The loom was hard to source so I just found spade terminals to fit the Ignitor pins. You will have to use the computer. If you need a hand make a thread, I'm sure we can probably help.

Backwards? What am I missing? 85 and 86 are the relay's trigger coil. In this example, the coil negative is coming from the reverse indicator light circuit. The positive is coming from the battery, thru a pushbutton. So- in order to trigger the relay, 1)the tranny must me shifted into neutral, so the negative is there, AND 2) The pushbutton must be pressed, delivering the positive- right? Now that the coil is triggered, it allows battery positive to flow FROM 87 TO 30, delivering it to the starter solenoid- yes?

Mostly u are right
But generally
30 is power
87 goes to the accessory
85 is power in
86 earth
U can mix 30 and 87
But u can't always mix 85 and 86 because it can reverse the magnetic force so rather than pulling the switch closed it forces it further open
This is the way it was explained to by our auto sparky and the teacher at tafe (trade school)
And how u would be expected to do it at work
Your other circuit is correct and I pretty much copied u there

Ahh, I see. To be fair, I think I have always used 85(-) and 86(+) and never run into difficulty.
EDIT- I just did a Google image search, and am seeing a LOT of 85(-) applications. I really do not think it matters...

I too don't think it usually matters but it does in some cases hence we were told to do it one way
Also if u had a load on one vehical it would make diagnosis easier if they are all the same
So I guess u could do it either way
As long as u do them all the same
EDIT
Ha I did a google search
There is a good mix
In fact It seems many American site reckomend
It your way?
I wonder if your relays are differant
I wouldn't put it past them to do it differant to the rest of the world
