OT-What is it that goes/wears that makes the compression go down? Rings, poor nikasil that wears off, cyl too thin and goes out of round, the crank, termites eating through the domes.....? What is it with these BB's that they have to be rebuilt so often? I am very confused why you say what you say. Is this personal experience with these mods? Are you an engine builder/engineer in the know, just trying to figure out where all your knowledge on engines (and clutching) comes from.
These posts that are intelligent and informative have been screwed by people that are bound and determined to prove that they know something. I enjoy these posts and don't understand why they always have to go down this road. Sorry if I come off offensive, I am not normally.
"It is better to be quiet and be thought a fool than to open your mouth and remove all doubt"........the ramps in a tra do not move.
Flame away
While Joe is dodgeing the questions ......This one is real simple "HEAT"....It' pretty simple folks. 2 Stroke Get Very Hot. Touching points like your piston & rings as they cycle Up & Down the cylinder walls making compression will get very very hot. Every time you start and stop your sled the engine expands and contracts slightly at every cycle. Cold morning start up can be the harshest on your cylinders, ring & piston ....Also not allowing your coolant to cycle and cool your motor correctly is very bad on touching engine parts as well. Your light weight metal motor expands and contracts " MOVEMENT " just like those TRA ramps Joe & BJ.
Here's a question....How many of you guy's stop and hit the kill switch right away without allowing your coolant to cycle for a minute or two ?
Heat is the problem between the cylinder and ring and piston and can be the primary reason compression can be down. Doing a fresh "top end" is normal and similar to maintaining your clutch. Keeping a fresh top end in your expensive BB kit is cheap insurance just like running good quality octane to match the compression of your motor.
I own and have owned many BB kits both Poo and Doo & turbo Yammies. I know what they cost to build, I know how there built, and iI no what to cost to keep running correctly.
