jk47...
stick to working the oilfeilds as you have shown you really don't know **** about motorcycles
listening to your weekend wrench buddies is far from asking a PRO who does this work 8 hours a day 5 days a week for the past 40 years... me I am 37 and by talking to the older guys i have learned more in the last 4 years about bikes by being around REAL bikers/riders not the weekend posers that couldnt even tell you a camshaft from a reed valve
I worked as an auto tech for 7 years... I started because I loved anything on wheels, but after wrenching everyday, I lost the passion. I rode and wrenched on motorcycles before I had a drivers license.
Two of my so called weekend wrench buddies were privateer professional AMA Superbike racers in the 80's, that raced against the likes of Kevin Schwantz and Wayne Rainey. I have friends that are Harley tech, a BMW tech, a Ducati tech, and a Honda tech. Each of them have different ways to do the same thing.
As for the oil field, the work is quite lucrative, and allows me to enjoy my wheels on my down time. Working 300-400 hours a month is no joke, but the 2 weeks I get off at a time are sweet.
Too bad 2-smokes are practically extinct... I think the better comparison would be reed valve and valve...
