Linda's New Quad

Our lovely friend Linda has had a quad in mind for some time, and we found one on the local CL today. It's a 150cc GY6-powered quad with a Kaishan engine. I don't know what year it is, but it is a decent model with the Honda-style rear axle, long front control arms and a planetary-style reverse meachanism (like Kato's new buggy). It lacks the kicker that we have on our GY6-powered quad, so perhaps we can retrofit this one. It would be handy in case the starter quit, since I don't think you can push start a CVT.

Aside from needing a better quality air filter and some general Loctite application, this one is ready to ride. Here's the happy new owner.

Looks like someone has upgraded the rear tires already too.

When I took my CVT apart the gear is on the crank for the kick start. I think you just need to by a few parts. On the buggy the hole for the kickstart shaft is occupied by the exhaust mount.

That's what I figured. I want to take our CVT apart for inspection anyway, so I'll remove the cover on Linda's CVT at the same time and see what the difference is. Maybe I can pick up a kick start-equipped cover on Taobao.

lol I sent that add to a friend this morning as he is looking for one for his g/f but i guess he is sol now lol.
we removed the kicker on Kellys GY6 as there isn't enough room to actually kick it over so you are welcome to have the kicker if you can find the proper cover (or we can just swap covers)

Thanks! I'll figure it out after I compare our CVT to hers.

It was a remarkably sunny and dry day; it would have been a perfect day for riding. Linda is thriiled with her new purchase. We hope to get together soon for a ride.

You noticed. She just moved into a brand new townhouse, so we need to dirty up the garage a bit.

After considerable procrastination, I finally tore into Linda's quad today. I had dismantled it a couple of months ago and cleaned the carb, but that's as far as I got until now.

I installed the carb and a pod filter, using the original air box boot. I think it'll stay relatively dry, since it's out of the stream of the rear wheels. The bonus is that the filter is now easy to remove.

I also removed the CVT cover to inspect the belt (it's fine), and to clean the snorkel filter. Here's the CVT:

The snorkel filter was a joke, so I cut a new one out of some bulk Uni filter, and then secured it with a new stainless socket head cap screw and nyloc nut.

The new snorkel filter is much thicker than the crappy OEM part.

This quad is equipped with a planetary device for reverse, and it's mounted on the output shaft. I drained the goo out of it, and then flushed it a couple of times with Varsol, and then once with gear oil. I then measured 120ml of gear oil and filled it up. This is the vile substance that came out originally:

I also drained out the rear gearbox oil, and it wasn't much better. It's now also full of new gear oil.

The front brakes were making an alarming clunking noise, and I soon discovered why. The backing plate was not engaged with the spindle as it should be. It is now. Here are before and after shots.

While I had it apart, I confirmed that the brake shoes have sufficient material left on them, and I lubricated the cables with Maxima Chain Wax. I also snugged up the tie rod ends and greased the ball joints.

Interestingly, this little quad is rather well made. I jacked up the front of the unit and removed a front shock, and then I cycled the front wheel all the way up and down. There is nearly zero bumpsteer, and there is zero bumpsteer within the operating range. I'm impressed.

I also found that the chain was way too tight, but at least the PO had replaced the stocker with an RK. I adjusted the chain and then lubed it with Maxima Chain wax.

The swingarm is really well built, and it incorporates a spring loaded chain idler.

I'll need to double check the chain tension when Linda is aboard the quad, but it's much better than before.

I also changed the engine oil, and used Mobil 1 synthetic 10W30, since there is no wet clutch to worry about.

My next tasks are to set the valves, procure a large battery and build a box for it and procure and install an inline fuel valve. I can't believe it left the factory without one.
