While lubrication is important for every motorcycle engine, newly-built motors usually require an extra supply of oil to reduce the friction and heat that occurs during break-in. This is because the "new" surfaces are actually rough. Eventually, after break-in, these surfaces wear smooth, which in turn reduces the amount of friction that causes excessive heat buildup inside a new engine. To insure that the pistons get proper lubrication during the break-in process, the builder must put a crosshatch pattern of fine scratches on the cylinder walls. These tiny grooves act as oil troughs and are put in the cylinder walls by running a honing tool up and down the cylinder bore. Because your engine is new, perhaps oil is being used up in the break-in process. My guess would be that any excessive oil usage will slow as your engine's cylinder wears smooth. I recently installed new piston rings and piston on my scooter and have found that the engine does run hotter. I didn't redo the honing of my cylinder though, so I'm a bit worried about how well the rings and piston will break-in. Also, I've noticed that my speed has decreased about 5mph since installing the new rings and piston. I'm wondering if because the engine is so small the extra friction from the new rings against the cylinder walls is reducing speed. |

Tip from my uncle regarding brakes: every time you ride, grab the brake lever (while stopped) and YANK it as hard as you can! If something lets go...well, better that than the same thing letting go on rush hour traffic! He credits that with finding a bad brake line on his Yamaha just BEFORE he was about to leave on a 2-hour ride through mountains!
(He called & told his brother he'd be along shortly, replaced the line, bled the brakes, and was only 20 minutes late.)

Again: you WANT it to do it in the driveway, not the expressway!

Jaraxle - If some of us do that we will be destroying a lot of brake levers and master cylinders. You end up putting panic stop wear on the entire brake system everytime you leave the driveway which could also lead to the on the road failure that you are trying to avoid.

I will test my brakes, but I don't know about yanking it!
