I'd say check your tire pressure and adjust it according to what everybody else has said. Some air loss is normal and the psi will fluctuate with temperature change. What you can do to check for a leak is get a spray bottle and fill it with water and a few drops of soap. Then spray the area in question and see if any bubbles apear. The soapy-water mixture will help stay in place and will bubble if there is a leak. I would say do this with the nail still in the tire so if you see there is a leak (slow one) you can ride to the desired location to have it replaced. If you don't see a leak with the nail still in the tire, then pull the nail all the way out and spray it down again to check for leaks. Hope that helps some.xNinja said:What is the PSI suppose to be at on a 08 Ninja 250R? I dont have my manual and I found a nail in my tire and want to see if im losing any air
