HT 80cc Longevity Kings: List your milage and key to success!

Read that someone has over 6,000 miles and still going strong... Since I'm new to motoredbikes and have the 80cc Chineese 2 stroke as my introduction to the fuel sippers. I understand re-torquing heads and obvious outside parts for good maintenace before each ride. But what about the not so obvious, like good oil that worked for you. Flat or hill terrain. The 6K post stated wide open throttle for maximum oil to the crank and bearings?

Also i have a left over part that looks like a bearing press. But no directions on how or where to use it? Do I need to check motor part with it before break in of my new motor?

16:1 stated in black and white direction booklet for fuel ratio. Is more better or will this delay piston seat to cylinder wall.

18:1 in the full color description manual.

the do hicky thinga ma-jig Is a fly wheel puller in a sort of way.
You don't need to worry about that tool unless something goes wrong.

AS to the Ratio.
16 to 1 is fine for breaking in for the meek. IF you tend to worry then run the 16 to 1 for a few tanks

Careful and safe is always best when it comes to moving parts and heat.

cheers

just went to Castor927 ~25:1. It hums at 25 mph at about 1/2 throttle. at this point I'm trying to get my clutching down for smooth take offs. I am wondering if an ounce of some other oil/stabilizer will help with our E10 fuel.

my key: warm up-always.
 
Castor 927 @ 25:1 is in first place for the moment

Bob you have been an excellent resource of info since my feeble "PM" questions answered with the understanding of the learning curve for a noob.
Thanks!

Warm up go it!
1- How many miles have you gotten or have on the HT?
2- Exhaust mods for 1/2 throttle at 25 mph?
3-And taking off with the clutch? Is pedal start easier on the clutch plates for longevity? Just asking...maybe they out last the motor? (noob Q)

I hope to see some competition and bragging rights surface from the Kings.
Because I want to learn from the pros !!
Thanks from the Oregon rider with hills.



PS: Second break in ride was clocked with my wife's Prius at 15mph and 20 mph. Speedo quit working. Does the electronic ignition or Plug wire cause interference with the Cat Eye front tire speedo?
 
So have you modified stock porting or intake and exhaust manifolds

I see performance of air and gas flow enhancement to stock delivery. Making a seemless transistion from intake manifold to cylinder intake port and the sam for the exhaust side. Just wonder "how much of a difference" is noticable in MPG and increased HP.
 
Castor 929 at 25:1 is too much oil. Try 40:1 and you'll like it. At 25:1, you are increasing risk of a stuck ring and fouling a plug. The 20% castor in this oil goes a LONG way in protecting your engine.
 
2,800 on my HT. I splurged for a jug of castor early on. Now because I'm poor I'm running 1/2 castor,1/2 valvoline from the auto parts store. Since I converted over to MOOP2 it does not collect any dust anymore. I've been adding Valvoline 2 stroke oil to my castor container so by now it's probably 25% castor 75% Valvoline.
(But Cronus is catching up in miles.)
My HT is showing NO signs of weakening whatsoever. In fact,sometimes I think it's actually improved overall.
My secret is I ride it like an old man on a bicycle with a little more speed. But not a whole lot more. I don't lug it but I don't wind it out either.
I run 18mph MAX speed when cruising with the occasional burst but since MOOP2 has but the rear coaster only because I want this bike to look original I don't ride fast at all. My cruising speed I would guess right now is 14 to 17 according to the speed radar sign. 44t sprocket.
 
3200 miles on mine

3200mi and going strong on my early Kings motor. Still all the original parts. I used Quaker State 2 cycle from the word go. For those that put down this motor, and there are lot's of them on this site. Well the motor outlasted the bike! So it's now on Motoschwinn II.

I will admit ..
I have one of the first Bikes I ever Built ..It has been thru **** and Back.HeHeHe

It has over 4000 Miles On the " Rat BIKE "
And the steering head bearings and races are Wasted from all the pot holes i have hit at 30 mph Not to mention the salt damage from dropping it in the water off the boat:D
A couple Times ( I don't want to get into that one).

Anyway check out the video We made today for all the ..uhmm

Heavy guys that call me asking if the kits will carry them.:eek:

check it out http://www.youtube.com/watch?v=eDKGaDD6TQo

I guess these are unmodified or cleaned up motors.

Since I did not do any Dremal grinding on manifolds, I was wondering how many other motors did or did not? "Stock" is untouched out of the box like mine. Stock muffler too!
