Photos from the first real ride.

I only mixed a single cup of 16:1 so I ran out of gas and had to pedal back but the little 49cc engine did well. Need to get handlebars for an upright position though, my wrists were numb by the end.
Good fun!

What causes chain stretch is the holes in the chain plates where the pins go become oblong shaped over time.

Chain stretch happens more in higher power machines. These bike engines don't really stretch chains because they don't have a lot of bottom end torque, which starting from a stop is what will stretch a chain

NO, I'm just one "steadfast and unmovable" guy, (Stubborn...LOL), That is totally anal retentive when it comes to good maintenance as well as the overall safety of my bike, not only for my sake but for the sake of others on the road as well.

Yeah maintenance is the best money saver. Its crazy how a little love can keep things running forever. My dad believes in catastrophic maintenance instead of preventative maintenance.

My dad believes in maintenance only when he likes the vehicle. His pickup he has right now, he only fixes things when it absolutely needs done. He also says he will never have to change the oil because it least a quart a week out the rear main seal. However the V.W beetle with the empi racing engine he rebuilt, he won't go a week before checking everything.

Chains don't really stretch that much, but if the chain is too tight it will round over the teeth on the sprocket/s and make it seem like the chain stretched.

Chain stretch occurs in lower grade chains due to to high of a load being put on them. This causes the holes in the plates to become oblong shaped instead of being circular.

Stretch or wear? Me thinks they wear. Steel isn't elastic normally.

Steel generally is strong in tension, that means it wont snap off not that it wont stretch. Non hardened steel especially small pieces like in a roller chain will bend easily enough.

The reason it's called stretch us is because the chain becomes longer due to the oblong shape of the holes where the roller pins go.

I got a stem extender similar to this one, it helped so much with my back. I had pretty much quit riding the bike I put it on because of the aggressive geometry. The riding position was great in my 20's but not so great in my 40's.
