Definitely a project

[Steve Wood]

This one is gonna take some work for sure....carb and electrics and who knows what else.  One of my friends picked it up for me today in Temple.  Now I have to find a trailer and go haul it out here

[TexasT]

What engine and carb is it equipped with? Slide throttle like a motorcycle or a butterfly like a regular small engine? Had it sat with gas in the carb/tank? Kinda hard to check brakes and clutch without it running .
Looks like fun if you can get it going.

[Steve Wood]

Gy6 150cc. Jason picked it up for me. He said the brakes work. Hydraulic disks both ends. Someone had the carb loose and did not put it back. It's electric start with reverse. Have no clue as to when it last ran but it's been awhile.

The carb is a typical chinese copy and it's a regular carb.  New ones cost about the same as rebuild kits.  The GY6 is built all over Asia for scooters, karts, etc. This one is pure chinese but all in all, the karts were fairly well built.  I  suspect this one is from the early 2000's.  Seats are gone to hell and they are expensive. 

They do sell a Mikuni round slide carb to replace the factory carb.

Parts are readily available for just about any part and it will be expensive but buying one in good condition would be even more expensive, I suspect.  I decided this one would fit the bill for a project as the frame is straight and not badly rusted.  Jason sent me a bunch of pictures but pics are always deceiving to me...anyway.  It came out of Temple.

Sweet that thing is loaded.

[Steve Wood]

I wanted one that was originally built over here but even those used the GY6 often.  Lots of versions of that engine but they look easy to rebuild to me.  I wanted one with reverse.  This time of year, karts are getting expensive-junk and all.  I missed out on two but I think this one fits the bill.  Help to be lucky and don't have to buy major stuff right off the bat but the seats appear to be the worst thing on it and the factory ones are about $175 each and that ain't cheap in my book.  The entire engine/transmission is about $800 new but, patching it up should not be too bad.

That thing got at hemi?

[Steve Wood]

I have a new 212 hemi sitting out in the shop!  Surprising how good a reputation the various HF Predators have and there are a lot of parts for them to really kick the hp up.

[nocooler]

Can you swap it easily or does the swing arm on the gy6 make it a pain?

[Steve Wood]

Most of the better ones that use a rear swing arm and a more conventional engine are built similarly.  Should be pretty easy to do.  The 212 Predator is probably the most popular swap but there are a lot out there going way on up from there.

As I wanted reverse, I decided to aim for one of the GY6's with a reverse box built in....they actually often have more hp than the 212 Predators out of the box.  Ideally, one of the 200 GY6's would have been my preference as some of them are pretty strong.  I think they are more like 170-180 actual ccs but I think a big bore kit is available that takes no machine work.  Larger does.

This kart is listed around 480 lbs so it's pretty beefy.  Approximately 7ft long and 4 1/2' wide.  I wanted full suspension due to the rocky terrain.  The karts that have basically no suspension, or rear only, are better/safer if you don't have to contend with rocks, imo.  Sure are a lot simpler.

If it has compression and the oil in the crank case isn't diluted with gas I am pretty sure you can have it running in no time.
I pulled my Kemp shredder out on sat. Kohler Magnum 8 powered. Checked the oil, pulled plug and checked for spark. Pulled the carb off mustie1 style and pulled bowl, jets and such and bathed it down in carb cleaner and a good squirt of air. Reassembled and it started  on the third pull with some  premix gas squirted into the cylinder before securing the plug and wire. Hadn't run in several years. Then the real "fun" commenced shredding up the pile of remnants in the back yard.

[Steve Wood]

Hoping it just sat and then would not start due to a carb plugged up.
The oil in the crankcase does not look like it is watered down but I would know more when I bring it home.  Going to go over to Jason's Saturday morning and haul it back home.

New carb is only slightly more than the rebuild kits so I ordered one along with a plug, filters, etc.  If it has spark, it should not take long to see (assuming the electric starter works LOL)

Unless severely abused, these things usually don't get played with long enough to be worn out...but they look easy to work on.

What is that, Steve?  I thought it was the Honda Odyssey but it's blue.  I found those things to be very bouncy! 

[Steve Wood]

This one is a TrailMaster 150 XRS.  They sell about three different physical sizes and this is one of the larger ones.  Basically, all go karts are made in China today and most of them from one factory as I understand it.  It's confusing because they often look very similar with just minor changes in bar design and such.

There is another brand called Hammerhead which was an American kart.  The company is now owned by Polaris but the kart is made in China and looks very similar to this and many of the parts are interchangeabl e.  The Polaris version is a little more upscale in features in some ways, but the kart is about 95% the same as far as I can tell.

Most of them are powered by the GY6 which I think may have originated in Taiwan but is made all over the East now.  Originally, they were made for scooters primarily.  The one in mine has an internal reverse gear built into it.  I don't know what the smallest one is size wise but mine is a 150cc and had about 8.5 hp.  This kart was built for offroading and probably topped out a bit over 30 mph but had pretty good climbing ability.  CVT transmission and is geared pretty low .

I know they built some that were 200, 250, and 300 cc.  I think the 200 was actually 179 cc but they like to round upward.  The Honda Grom has a gy6 for power but it may be built in Japan.

I changed engine and transmission oil in mine along with giving it the first grease job of its life as far as I can see.  I played with the wiring and seem to have spark but I am not sure if its is strong as it should be.  Apparently, it has not run for at least four years from what the prior owner told Jason.  In fact, I don't think it ever ran for him if he understood the seller correctly.  It has been sitting out in the weather and when I drained the gearbox, I caught the oil in a measuring cup and the first 1/2 cup out was water.  I think rain got into the breather.

I measured the compression today and only got 60 psi which is not enuf to run in my experience.  I shot some oil into the sparkplug hole and it jumped up to 185 but came right back down after a few cranks and rereadings.  It tried to run when I sprayed some ether into the intake but would not really kick off.  Had no carb on it at the time so that did not help it air fuelwise, I guess LOL

I guess I will pull the valve cover off and see if the rockers are way loose so that they are not opening.  If that does not make a difference, I guess rebuilding it is on my agenda.

That little hot pink car in the corner needs work too

[Steve Wood]

The oldest girl was 12 on the 7th.  My son bought that one for her when she was about 5 and she was terrified of it.  It would run a short time and then take 18 hours to recharge.  It ended up in the corner piled up with another much smaller one.  The other day before they came up I was going thru the shop throwing away everything that I could put in the truck and haul away.  I started to throw it away because the battery had disappeared it was just taking up space.

I got to thinking of the two smallest kids-especially the three year old who is not afraid of anything.  I bought a utility battery and adapted the wiring so it could be connected.  It will burn the tires when you give it the "Go" and only takes an hour or two to charge after being used all day.

It did not go unplayed with!  Even the 12 year old was throwing a fit because she was not getting to drive HER car.  Now I am thinking of putting a 20v drill battery in it.  I watched a youtube where a grown man was doing wheelies on that exact same pink car after doing that and he had to put a voltage limiter in it so his kids could drive it.  Fisher Price missed the boat on that one.
