When to clean carbs and Adjust Valves
I have a 2010 Ninja 250r Its at 10k miles already and previous owner told me that he hasnt gotten valves adjusted yet or even carbs cleaned because the carbs didnt show any signs of needed cleaning. So my question is, how do i know when i need a valve adjustment and to clean the carbs? When is the mileage that i should b cleaning them at? Thanks!

Valve adjustments at every 7500 miles. As long as the bike has been running, you shouldn't be needing to clean the carbs. If the carbs sit long for a month or so WITH fuel in it then maybe. Anything longer than yes. Really, if the bike runs fine, doesn't have issues with hard starts, sputtering, than the carbs are most likely fine.

http://www.ninjette.org/forums/showthread.php?t=10577 I usually inspect my plugs at every valve adjustment. If they're still good I pop them back in. The spark plugs will tell you a lot about how your engine is running.

The X's are merely tick marks, meaning you do check those at those mileages.

my routine:
oil change every 3.5k miles. valves, oil filter, cooling system every 7k. usually the chain and sprockets last around 10k. inspect all bearings and mating surfaces every 15k.

Include service of cam chain tensioner. Plugs are cheap, just replace them. Be very gentle about torquing them down, the holes in the heads strip easily (expensive repair). http://faq.ninja250.org/wiki/Changin...rands_to_avoid

just some extra info on this. over torquing the plugs might not strip threads immediately. but an overtorqued plug will stuck itself in the plug hole to the point its welded in. after that, trying to remove the plug will simply shatter the porcelain and you're stuck with the bottom half of a plug in your head. which means you get to remove the head from the engine (not just valve cover- the entire head), drill the remainder of the plug out, tap to a bigger size, put in a helicoil and a new plug.

+ New plugs have a crushable gasket (metal ring) that gives some, avoiding excessive torque. The gasket of the old ones has been crushed all the way down and the transition between not enough and too much is a more drastic step, being another reason to replace the whole plug by new. Not to be scared, just careful
