Mini Jr's Quad Build

[MiniFighter]

Hey Guy's, Few of you would have probably heard me talking about the mini quads my kids have from time to time. And since my young fella is always by my side when im tinkering i thought I'd get him his own build and thread going.

Inspiration behind this build is from the insane quads at Pocketbikesunlimited in the US. Our build will be based on the pic below

We were going to base it on something a little more aggressive that these guys build, but ended up choosing this one.

So started removing the broken bits and stripping it down, well Jackson did i just helped with the tight bolts. This is the donor bike (note: i had to build a standalone bench just for Jack at a better height...just for him )

After some WD-40 and a few minutes of tinkering we were starting to get a pile happening.

I let Jackson have free range of what parts i had and this is his pile so far. He couldnt decide between the two oil coolers, but if we stay with the 2 stroke (like above) we obv wont use either.

After some thinking, and drawing i designed some brackets that i will need to make, so went and got some 1/4 plate and also some 1/8 plate.

Brackets to be made are: Swinger mount brackets and Upper shock mount. Ill be making the brackets through the week and gotta get the MIG off the old man to attach them to the frame.

Bit of a sit together to get measurements.

Note: Most parts so far will be replaced once they are known to fit. More for a "mock up" rather than using the good bits. Will also get a slightly longer swinger.

More to come soon!

Mini & Jack.

Wayne will the shock angle affect how it works ? In the pic it looks like it's not to far off horizontal, wouldent than make the shock realy hard ?

 

[shann]

No... It's basic leverage

As long as it doesn't push past horizontal too much on the rear swinger it should be fine (if it does, it might result in some collapsing).

In the pic the shock is cable tied to get an idea of how it will fit. The bracket i made and welded on is around 50mm back from the one its cable tied too.

O ok sweet just thought id ask . So have you decided on a engine yet?

MF, I figured a way to strip and combine three of the 33cc pocketbike race engines in to a compact 99cc triple. Some expansion chambers and a Comet clutch and it would sing the prettiest song on the island
