my china Dune Buggy, 110cc build/modify

[aussie_140]

yeah you sure would need hospital cover haha. cbr1000rr engine would be better

 

[my67xr]

yeah that'd go ok, or a Hayabusa turbo , lol

 

[DHZ_XR8cing]

you have spent some time and effort building that beast up. Its looking great. Well done mate.

 

[my67xr]

i need to finish it off in the next couple of weeks, then take it back up the farm.

just got a txt on my phone,
a mate offering me another bike, a 1983 IT250 with an IT465 motor in it.
damn, i need to sell some stuff, i want it, lol

 

[DHZ_XR8cing]

Does the motor give enough charge to keep th battery going to run them lights??

The old 465 was a machine. Rattled every nut and bolt loose every ride.

 

[my67xr]

yeah standard lighting/charge coil on them is enough to run 60+ watts
i am only running 58w though them atm.
i want to get another pair of the Led MR16s 9watt, in warm white.
they are more of a natural daylight colour.
that will drop the total wattage being used down to 36w, too

we dont use it at night time that much, it's too cold in the winter time anyway.

I like the custom made cover. It looks fantastic!

thanks,
the corflute roof?
that was to help keep the sun off and out of your eyes etc, then i customised it a bit more with the spoiler and pod filter mount.
and what dune buggy doesnt need some flames too? lol

some pitbike shops sell them, and ebay too...
they start with the base model and 90cc iirc and then they go up with bigger better and more expensive models.

here are a few more updated pics too,


the mountain bike RST 750lb rear shocks mounted up to help out the stocky china ones,
it corners a lot flatter now with this setup, and hasnt bottomed out yet either.

rear frame section reworked and painted, new battery mount finished, swingarm strengthened underneath

another pic of the battery mount, with a H/D 60amp fuse and wiring, also added a rear starter motor button next to it, this is goood for troubleshooting the motor etc,
you dont need to be at both ends of the buggy to try and start it.

after 3 days of thrashing it, bit of red dust
the rear engine mount broke the factory china steel mounts again, broke through both tubes just below the bolt/mount point.
so i cut a bit of 3mm thick steel strap and temporarily screw it back together to get it through the last day up there
im not sure if you can see it too well here though.

more dust, getting ready to pressure clean it

my 2 boys in action, ripping up my minibike track, lol

it is a bit quicker than me on the bike through the corners too, but on the straights things were a bit different,

here are the rear subframe engine mounts all replaced/repaired now

i just need to make a mount to fit the muffler again

cheers, craig

 

[lets ride]

cheers mate

 

[headsmess]

dam! some good fabbing skills there good to see mods done properly! decent mods too

other than a shifting box, these dont need anymore than a 110! well, maybe when its gotta lug two runts around it does...

the flogging we gave my mates one! at least four motors later... still pretty stock, still pretty ugly. hammered it into the ground and never got past third usually...

i hate how the motors on the swingarm. worst thing with china buggies. unsprung weight. yucky. not easy to cure either...

 

[rotn50]

Wow craig, she has come along way mate, i really like the twin shock setup on the rear, is the buggy hard to start or any bogging with the snorkel up thru the roof or does it get adequate supply of air mate.

 

[my67xr]

thanks guys,
yeah the manual/semi auto conversion i was speaking of at the beginning of this thread might not be happening anymore.
the buggy still gets up to about 70 with me and my eldest in it.
the only thing that has happened to the motor was the semi auto clutch wore out.
the plates had no friction material left on them.
i replaced the semi auto clutch with a full auto clutch, the type with 3 shoes that get thrown out to the flywheel as the rpm increases.
this new clutch has held out really well.
the way the motor is mounted isnt ideal, i agree there, but it keeps the rear tyres on the ground though.

i have seen a decent setup that'd be perfect for a swap into a buggy like this
but it'd need a bit of custom work to mount the motor to the back of the frame, then setup an independant rear end on it.
it would have a couple of driveshafts with cv joints etc, and run an inboard disc brake too, so more ground clearance.
get a nice yx160 motor or similar and mount a forward/neutral/reverse gearbox off the back
they seem cheap enough ?

mick,
it takes maybe 15-20 seconds to fire up first thing in the morning,
then it starts within a couple of seconds for the rest of the day.
i didnt notice any difference when i fitted the snorkel, except the airfilter now stays clean.
it goes pretty hard at WOT, plenty of cool fresh air, and it's pretty responsive of the line too.
the carby has only been tuned with the standard jetting too, i havent even had the fuel bowl off to see what jets it takes.
i do know the main jet needs to go up a size or 2, as the clip is sitting on the bottom slot of the needle.


the used/worn heim joints that i used for the upper ball joints have started to clunk a bit lately,
so i have ordered some Ultra High Performance/Ultra High Strength ,PTFE/Kevlar Lined 7/16 male Heim joints
from McGill Motorsports in the UK, and the proper High Misalignment spacers to suit.
the spacers i have in there now are custom ones i turned up in my drill press.
the new parts cost me under $50 for the 2 heim joints and the 4 spacers,including delivery,
where as if i were to buy them locally, im looking at around $75 for a lesser quality heim joint, and that is for each one here too, then the extra for the spacers too

 

[rotn50]

Good stuff craig, shes def a custom mate, the three shoe clutch is a good setup and dont see them much at all as they were an older setup in the days, but in saying that the nowadays stock semi clutches i see heaps of and replace heaps of, one today had absolutely zero plate on one of the combined steel and clutch plates. The steel very often tends to become discoloured and rusty coloured, prob the junk material they use, wouldnt hurt getting a stock honda semi clutch as the honda boys would ever rarely change a clutch id imagine. The jeep clutch was very strange, as i would be WOT in third it would then scream as loud as say ten fanbelts squealing, changed it over and havent had that prob again touchwood.

 

[zwebx]

no torque converters for small engines yet?

 

[my67xr]

thats basically what the full automatic clutch is

 

[motorman]

I gotta say this is the sickest buggy build I have seen in a long time.

You certainly know your way around the tools. Very good quality work.

I would be keeping in the back of my mind when your boys get a bit older slotting in a 160HO.

Man how sick would be with a 184 and V2!!!! Aaaaahhhhh that would be so much fun.

Appreciate you taking the time to post so many pics for us all to drool at.
