What is the effects of new pistons especially bigger ones in a daewoo lanos 2000 model, can the sound of the car change compare to the standard pistons?


unlikely
bigger than standard pistons are measured in .010" increments and will require a rebore of the cylinders to fit them
most people fitting over size pistons to gain more power generally increase the size of the exhaust system and fit extractors as well
that will change the tone of the engine , but pistons alone will not

Hi, i have honda spada 250 vt, and it needs to change the pistons and the pistons rings set, is the honda 250vtr will fit it.


Your question is if the pistons and rings off of a VTR will fit your VT. Chances are they will, but IMO this isn't a good idea. If you blew pistons and rings, you should buy new pistons and rings. In which case why not buy the ones made to fit your bike? They should be equally available.

How do you enter ln+ or- another number and ln/ a number ln+ or- ln


To calculate a natural logarithm (logarithm in base e) use the key marked [LN]
Usually you type in the number then press the LN key.
Before you proceed further try ln(4)=1.386294361, or ln(10)=2.302585093
If that works for you go on. However your expression is ambiguous. What is in the numerator and what is in the denominator. As interpreted by the calculator the two ln(7) are not part of the fraction, so they will cancel one another leaving -2ln(5)/ln(3)
With that calculator you will have to (ab)use parentheses to make sure that the arguments of the logarithms are the intended ones.
Here is the order of key presses

( 7ln -(5ln*2))/(3ln-7ln)
The result is 1.502382734

Using appropriate properties of logarithms, rewrite f(x)=2+3ln(1/x)


At first, y=2+3(ln1-lnx), logA/B=logA-logB

You have to know that ln1=0 because by the definition e^(0)=1

And finally y=2-3ln(x)

See the graph of this function on the image below

Can not get rear break piston to compress to allow for new pads


The rear disk brake piston does not compress back into the caliper, it has notces on the caliper piston that a tool fits into and the caliper piston is actually turned or screwed back into the caliper, and a notch in the piston must also be aligned to fit the the small protrusion from the backing plate of the inner brake pad.

The brake tool can be obtained from most auto part stores, and it is usually square with protrusions sticking out from the sides in different patterns to fit various caliper pistons, and it usually attaches to a 3/8" drive extension and ratchet.

Do not compress this type of caliper piston because the caliper can damaged.

Is there a certain tool you have to have to compress the rear pistons when changing the brakes on a 2003 hyundai tiburon


Normally rear disk brake pistons have notches on the top of the piston that a tool does fit into (usually a small square shaped tool with protrusions that fit into the notches on the top of the caliper pistons and this tool usually fits onto a 3/8 drive extension and ratchet), and the piston is then rotated down into the caliper, it actually screws into the caliper. You do not want to compress this type of piston or you will damage the caliper and piston.

Hi how do you tuneup a yamaha fzr250 2kr, thank you for your help.


Your bike has electronic ignition. There is nothing to set or reset on the timing. Change the spark plugs, adjust the valve lash, change engine oil and filter, clean or replace the air filter, lube and adjust the chain and cables, inspect the sprockets and wheels, add water to the battery if needed, wash the bike. That's pretty much everything the dealer does.
