This article concerns everyone who just bought a bike pit online and wondering what to do after assembly!
Most manufacturers manuals and other resources will tell you the same when the engine is the first time
do not run the bike for more than two-thirds full throttle and avoid high rpm the first two hours of operation. Often, you are advised to drain the oil after two hours of use and quality 10W40 semi-synthetic 4-stroke engine oil.
Because I myself a new two SSR pit bikes, I was browsing through a very reputable pit bike forum (pitbikeclub.co.uk) looking for some info on assembly and of breaking and stumbled upon some very valuable information. This article is a brief summary of the newsletter article written by Motoman found. Motoman is a very experienced superbike tuner, whose own Newsletter (Power Magazine News).
This article discusses the "Break-In Secrets" very controversial.
"Links to this article now appear on hundreds of motorsports discussion forums around the world. The reason for this is that over time, large numbers of people have made a direct comparison between my method and theowner the manual method, and the news that success is spreading rapidly. "
" the result is always the same … a dramatic power at all times RPM. in addition, many professional mechanics disassembled engines that have used this method to find that the condition of the engine much better than when the manual break-in method was used.The things that page so controversial that there have been many other break-in articles written in the past, which contradicts what has been written, "
Motoman wrote.: "burglary Secrets" after successfully applying this method to approximately 300 new engines, all with great results, and not without problems. So I advise you to consider your advice!
According Motoman, just follow the manufacturer's instructions, you risk permanently reduced output of about 2-10 percent. A direct result of a burglary will be too tame leaking piston rings. This allows the pressure to inflate the crankcase acceleration and suck oil up into the combustion chamber during deceleration. In other words, power loss and permanent contamination of the engine oil. The only solution is to get a bad break will be: re-honing of the cylinders, install new piston rings and start over again. words..you be different to engine separated!
You only get one chance to break the motor is correct! I will explain why and how.
properly break in the engine all the piston seal. Results in a good break a better fit against the cylindrical surface of the piston ring. This prevents leakage of the pistons. New rings to wear a little to close the hole all around. If the gas pressure is strong enough for the first mile function (open the throttle!), The entire wear surface of the ring roller to seal the combustion pressure as well as possible.
So what's the problem too easy to break?
to the honed cylinder bore of the grid wall pattern that acts as a file, so that the rings are worn. The rings quickly wear down the "peaks" of this roughness, regardless of how hard the engine run.There a very small window of opportunity that rings to seal really well … the first 20 miles! If the rings are not forced to the wall quickly enough, you can use the roughness before they fully seat. As it happens there is no solution, but re-hone the cylinders, install new rings and start again.
SO … the best advice I could find a break in the motor
1) Run hard! (Specific Methods: breaks into the dyno, the street or the racetrack … look Motomans 14-page article
2) DO NOT use oil synthestic ! Updates to the oil as soon as you receive your bike, before stopping when we can not be sure of its quality. Use Valvoline, Halvoline or similar CAR OIL 10W40 oil. Cang and oil filter after the first 20 miles !! After two days of tough competition can change the favorite brand. Check the article to find out why.
