Should my 250 tc make valve noise

The loud noises seem to be a feature of newer front loading machines. We bought a Maytag and have had similar issues since day 1. We were told the bearings are the problem. They don't last and make major noise as they wear.

check air fuel mix seems like bike is running rich

if its a 4 stroke and its the breather pipe then your getting pressure build up , what colour is the smoke , white or blue ? white is water and blue is oil ! water could be a seal or gasket leak , oil could be valve seals or stems or compression leak !

if loss of power also it sounds you damaged the valves and guides and seals ! strip head !

You may need to adjust your valves.

Is this bike a two stroke or four stroke.Meaning do you mix oil n gas,or dose it run on straight gas .If this a two stroke,its normal to blow blue smoke,but not that bad.Sounds like the person before you put to much oil in gas or piston rings are shot.There are exact oil to gas ratios you must follow with a two stroke engine.If you dont, you can have all kinds of problems.

Hello Brad...every brand has there own valve clearance to follow, you might contact Husqvarna distributor in your place, for sure they know it.You can play with it and you'll notice a noise or a smoke once your opening is not right.

The rmz and kxf 250 2004-05 is a shame for both suzuki and kawasaki, they worked together to create a 4 stroke engine but failed.The first thing to brake is the waterpump. So everybody has to buy a new waterpump, but not the original one because it was a failure, they all broke and some motors got destroyed. The second thing is the valves and you can mostly reshim them once and then you would have to buy new ones that will also fail after a little use.The last thing that i know of is the camsaft, both the camsaft and valves are weak and wont tolerate any heat and you cant really ride the bike like a real offroad bike.
This is my personal experience.When i bought my bike, everything in the motor had been replaced. Probably because the waterpump failed.Nothing was wrong with it and it was great, great in cold starts and the motor ran great. But after 2 rides 10 hours tops it was hard to start, so i went to the suzuki dealers and they checked the time, set the carbonator and reshimmed the valves.The motor ran for 5 minutes and then was just the same as before. Then they told me that i would have to get new valves.But then i went to check around and everyone that i asked something about these bikes said that i should have asked them before i bought the bike so they could have told me that these bikes will never work properly.And here in iceland it's better for me to throw my bike away and buy a new one, a bike that is not older then 2006.
Its costs 250 dollars just to reshim the valves and set the carbonator.New valves cost around 520 dollars and the suzuki dealership takes around 280 dollars for the work of installing the new ones.

Is there any area on the bike that is covered with what seems to be "wet dirt"? It is entirely possible you could have a blown seal and are therefore dumping oil. If the dipstick is showing nothing, there is not enough oil for the engine and it will seize so don't run it until you locate the source of the leak.

Unless the bike has constant white or bluish-gray smoke coming out of the exhaust all the time, it's not burning oil.

The tapping you are hearing could be a a lifter, valve, connecting rod...whatever it is, the tick started recently and you don't see oil on the dipstick, there is a major oil leak somewhere.

usually on the front fork area where the forks pivot there should be a manufacter sticker with the brand and year and most times the size also. Just a guess but my bikes have them.
