Chinese Quality Control Standards.

[Alaskavan]

I wonder if ThatsDax, or Chris Hill would consider selling an upgrade version of their motors? I would pay considerably more for an engine where I KNEW that the nuts, bolts, and studs had been replaced with quality parts. And I am in the market for a couple of them.

@BoltsMissing
Stainless steel cable inserts are the best...u get them for $1.50 at the Port Market on Sundays.Buy the loose ones in a box of 100.

@Van
Capitol idea....it shouldn't cost much more and would give great peace of mind.

 

[Alaskavan]

Actually, it sounds like Chris Hill already does quite a bit in the direction of quality control. I think I'll buy one and see.

Ok, the list so far.
Cover Plates Bolts.
5 @ Clutch Cover.
4 @ Magneto Cover.
3 @ Small Drive Sprocket Cover.
2 @ Crankcase on Clutch side.
2 @ Crankcase on Magneto side, at bottom of cylinder.
If you are going to choose Allen key bolts and they got the knurl on the head of the bolt, I used the grinder or the wire brush and smoothed it out.
I would not enlarge the holes in the engine covers, I'd rather make the bolts fit. That's my opinion, but probably a warranty issue if we mess with the engines bolt holes.
If I have missed anything on this, copy and paste the list and fix the list, please.
Next...,
Rear Sprocket
9 @ High Tensile Bolts.
9 @ High Tensile Nuts
9 @ Nylon Lock Nuts
9 @ High Tensile washers ( large )
18 @ High Tensile washers ( small )

OK, I'll try to explain how they fit.

Allen Key Bolt-small washer- to outer side of sprocket
That way the head of the Allen Key bolt has a small washer on the sprocket.
Inner side of sprocket;
Rubber-Plate-Large Washer-Small washer-High Tensile Nut-Nylon Lock Nut.
Next
Carburetor
???????????????
Better air filter or air filter element
I personaly prefer this as a deluxe upgrade kit, a carby with a mixture screw.
Name a carby or carbys to consider. It may be a personal choice, but for the general rider that wants no fuss, generalise a carby for the kit at least.
Remeber, we only have to nut out this Quality Upgrade Kit once.
Next
Chain Tensioner
Tuff call, we all have ideas on this one.
High Tensile bolts,nuts and washers and spring washers for the 2 plates.

The other day there was a bike a the pawnbrokers with these wide chain tensioner wheels with bearings on the pedal side.It had 2 of these wheels, one one the high side of the front sprocket and another on the lower side. Never seen this before but it was on a competition looking Mountain Bike. I will go back there and get some more details, but it looked like a factory standard item, therefore there has to be a replacement part for that particular bike. If it looks Ok and I can test it, then we see if it is a item to consider.
Fetor, it's at Klemzig Cash Convertors or if anyone is close check out.

???leave it up to some of you guys to fine tune the list.

Thanks

I think he does better than most suppliers,but(correct me if i'm wrong Chris) his nuts/bolts/studs/etc are basically standard issue.IF i could afford his engine(plus freight being the killer) i would jump at the chance.His engine/good expansion chamber/descent carby(even a clone descent carby)/optional packet of nuts,bolts etc,and u would have an excellent setup......truly excellent.

This is a list of everything I've done to my bike and works cool. There are many more ideas here but this list is what I have personally done myself.

Change your spark plug wire to wire or copper core

Make your own air cleaner(Haven't installed it yet. Pics soon)

Homemade Chain Tensioner

Easier clutch pull,longer clutch cable life

O ring the carby(lots of different ways on this thread.)

Muffler Mod

Stop blowing up your magnetos

Boost Bottle

Cable operated choke no more reach around

I also modified my kiddy trailer I found on Craigslist for a song so that the mount mounts on the right side of the bike instead of the left side. There's far more room on the right and now the happy time chain doesn't get in the way. Pics soon of that as well.

I guess the trick with these Happy times is to make them less identical with each other and more PERSONALIZED. That is what joy is.
Moop hit 1200 miles yesterday! I may throw it a party. He will be pleased.

We all complain about the lack of Chinese HT quality and consistancy in quality but nothing ever seems to get done about it.The same sub-standard engines and mounting kits are still out there and still failing.Sure their cheap but it comes to a point of diminishing returns when cheap only lasts a short time.
Our sponsors do the best they can but their under pressure from other lower priced dealers to compete.I don't profess to know all the answers but i would like to hear other peoples opinions.....can anything be done or are we just stuck with it?
My only solution was to spend more money and buy a 4-stroke "made in japan".If there was a 2-stroke HT made up to a standard and not down to a price i would have seriously concidered it.Please keep in mind i'm in Oz so freight costs also have to be factored in.
To me it seems "brand name" manufacturers are scared to make engines in the HT configuration for fear of liability......sad cos they would be extremely popular.

What does "HT" stand for?

 

[azbill]

torques,
HT stands for 'happy time'...the generic name we came up with for the chinese frame mount kits

Thanks AZ. Here is a picture of the chain tensioner I built. It works great.

I finally found a petcock that's correctly made from a racing car speed shop.
100 % brass, made on a lathe. They are catalouged and mass produced.

The thread section that screws into the tank is tapered, so it tightens as it's screwed into the tank. The tap is either On or Off.

Found this on a Google search, similar to what I'm using
