Default Making it last forever

I'd like to see an area for longevity on the Chinese motors. I'd like to have mine around for several more years.

Well, here it is, your own thread.

Here are my tips-

Proper break-in (ring seating)

Use enough oil, no less than 32:1- these are piston ported, non-injected, loose, sloppy unbalanced engines, they need all the help they can get.

Don't run them too slow or too fast, either is as bad as the other.

DON'T RUN THEM LEAN. If you even think you have a common intake leak, you do. Stop the engine and fix it or die. (the engine)

Don't run the chain too tight unless you like replacing the shaft bearings, chain, sprockets, tensioner, rear wheel, ect.

I like to think of my motor as 'refined stock'. I don't do upgrades for performance, more for reliability and to replace known problem parts. Like plugs, wires bolts etc. I'm ordering a K&N style filter, so that maybe a bit of a hop up but I think, better filtration is better for the motor.

After seeing Pablos jack shaft kit video, that will be a purchase I'll make this winter. There's a guy at the Evil Empire (other site) putting one on a Point Beach like mine, so I'm waiting for his experiences. After watching the video of him running all over town IN traffic! I knew I wanted one. The motor isn't straining at all. I think that kit, although a bit expensive for me, would be great for the motor.

Cool Re: Making it last forever

The only thing I really worry about is the bottom falling off. (mine) after about
ten miles I stop sit somewhere comfy and look at the bike. I have an all in one knife, some zip ties, extra plug, & Wrench and a very small pump & tire patch kit. I have an old army canteen mounted to the bars w/extra fuel. Weighs about a pound. Ta Da! Yeee Haaa!!!

I broke my engine in at 16 to 1 for ever. it worked so i just kept doing it.
one gallon of oil 128 oz at 8 oz per gallon of gas 16 gallons of gas 16 x 150 miles approx 2,400 miles. 16 gallons of gas at $4.00 per gallon $64.00
Now at 25 to 1
I use a castor synthetic oil mix. 20 % castor 80 % synthetic (with 2 oz of marvel mystery oil to the gallon to cut the carbon).
I also glued the engine together as well as the carb. to seal air leaks.
I use a home made paper air filter . A N-95 surgical paper mask glued to a holder, with a foam pre filter. I am still on the same air filter LOL. I check it about once a month?
I grease the stuffing out of the clutch . In three places. 1 the ball and pin, 2 under the carb, 3 and the bean sized blob.
Warm it up.
Going down hill pull in the clutch.
Blip the throttle to oil the engine at red lights. I like the noise also.
I go through rims , and chains like crazy .
I was going through brakes .
Until I tried something else a front hub brake.





I have gone through 3 full sized auto style fuel filters as well as about 3 feet of fuel line tubing.
I use catch of the day oil currenly mobil 2t racing with a rebate or a closeout sale because they are discontinuing it in Arizona. approx 2 dollars a quart.
Benol castor $8.00 a pint.
Marvel mystery oil Had it around it is an upper lube for cars.
I still have six quarts of mobil 2t . It was so cheap I would go in and buy it every time I went to checker auto.
