Rmz 250 valve problems
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.
Bike will not start
compression under 110 get's is questionable.
check your crank bearings and seal.
also clean carb and check float level
I have an 86 rm 250,replaced water and oil seals twice still getting water in oil. What gives?
The problem is common in 2 stroke watercooled bikes ,what happens is the head gasket leaks and the leaking burnt gases pass the gasket and sneak into the water jacket which highly compresses the cooling system and blows the water past the water pump seals and into the gearbox,mixing with the oil and making a vile mayonnaise mixture,make sure when you fitted the seals you fitted them the right way around the main sealing lips should both face their fluid they are keeping out and the impeller shaft should be free from and scoring or damage where the seals touch it.p.s im a fully qualified motorcycle mechanic with over 20 years experience so im not just guessing at an answer
What is the seal called that is on the drive shaft
It dependes on who you ask or which manual, you read but the main names are
counter shaft seal.
or drive axle oil seal
or drive shaft seal,
or sprocket shaft seal
the transmission shaft that the clutch is on is called main axle, the sprocket shaft is called drive axle\counter shaft
check the battery with a load test to see if there is a dead cell. go to a battery shop to have this done
My 2004 rmz 250 overheating
trail riding d'idnt provided enough air to make you're bike running cooler..and get you're head to warp a little and let pressure in you're cooling system. at least i would try a new gasket and some coolanol coolant to put in after....they get faster heat transfer..also you can put a higher pressure radiator cap that will keep in you're coolant...
2004 rmz 250 was riding started to smoke heavily
If it was white smoke coming out you may have blown a head gasket. If it is water cooled and there are no signs of external leakage then it only has one other way to go, inside.
If you have an oil dipstick, pull it out and check to see if your oil looks more like a milk shake sludge. Even if you can't see it, try dumping your oil from the sump and take out your oil filter. (unless it is a 2 stroke)
