Hi I have had this honda nsr250 mc21 1990 for the last 10 yrs. If I ride it every day it starts up easy next day, if I dont start it for a couple of days or week or weeks as I use car then it does not start easily.

It would need about 10 or 20 kicks before it fires up. when it runs it runs fine and I can feel the power in it.

So can someone please please help me. I like this bike and want to keep it.
only thing I can find is the kick is very light as if there is not enough power ie compression or some sort of electric fault?

The bike was rebuilt back in 1998 as it was thrashed by a racer and ever since this problem persisted.

I had it checked by a couple of m/bike shops no one could find any thing wrong with and now I have stopped spending money for nothing. I keep the plugs clean and replace them when necessary. I know enough about the bike to have done what I can, including mixtures, carb cleaning, throttle adjustment etc
