i have 3 dirtbikes, all yamaha.
One is a TTR-90, i am trying to sell it, because i out-grew it, comment if interested, i am based around Boston Massachusetts (thats in USA).
i moved up from the 90 to a TTR-125L. this is the nicest 125, no electric start, which i like, and it has a front disk brake. very nice trail bike for anybody.
after that i got my need for speed...i ended up with a 2-stroke YZ-85. this is a killer bike for anybody, and i am also trying to sell this.
COMMENT if you want me to go over the difference between a 2-stroke engine and a 4-stroke engine. if anyone is interested i will point it out.
So the crank-shaft that the engine spins as a result of the pistons moving ends up going in two directions (like anything, it goes one way, and it has 2 ends, so it can go another way too). so one end of the rod the engine spins goes to the drivetrain, the other end goes to something called a torque converter.
What this does, is it takes the engine's power, usually whats just being wasted, and it spins a little generator, this generator is hooked up to the battery, which in turn charges it! When you turn something on like the heat, radio, AC ect. it ends up taking power from the battery. not quite rocket science haha
the engine gets its heat from friction, and then you turn a little fan on, and BOOM heat to you.
ask any questions you have about bikes you want me to explain.
DONT FORGET TO DO THE POLL ------>
