How to get flywheel off?

I got my bike from a guy who had let moisture get to the flywheel, was really rusty in there. It is the flywheel typewhere the puller is like a hollow bolt, screw it in the flywheeland it pushes on the crankshaft inside the puller. I guess it is rusted to the shaft, I have tried everything I can think of. Tried an impacked, tap with a hammer, have let lay on its side an soaked with oil around it, and some heat nothing works any help wopuld be great thanks.

As anna14 said, crank down hard on the flywheel puller handle.

NEXT, give the center of the puller a couple of solid hits with a medium size hammer. If it doesen't come loose then tighten the puller by striking the puller handle with a medium blow from the hammer then a couple more VERY solid strikes on the center of the puller.

Hi, I own a 2004 roadking 9,300 miles on bike. I noticed my oil had the color of "hot choclate" I drained the crankcase and replaced the oil, i rode the bike for about 10 miles and when I...


Are you sure you're checking the engine oil. On your RK, the oil dipstick is a large knob about two inches in diameter located on the corner of the transmission. Now, the transmission dipstick is a small dipstick on a plug that you take out with a hex key or Allen wrench. I cannot understand how your engine oil could possibly turn that color in a short ten mile ride. I've seen this on transmissions that have not been serviced regularily. Moisture from condensation gets into the transmission and mixes with the oil. When the bike sits, the oil and water seperate and the water will cause rust to form on metal parts. When the bike is run again, the rusty water again mixes with the transmisson oil and makes it look like "choclate milk". I have never seen engine oil do this even though I've seen engines that have been overheated to the point of destruction. It sounds like water in the oil. If it is water, I have no idea how it's getting into the engine unless someone is putting it in there intentionally. I had one guy that kept getting water in his fuel tank. He blamed the gas station where he bought his fuel. Turned out it was his 5 year old son filling Daddy's gas tank up with the water hose. Check that oil again. Ask some of the parts houses around the area if they know someplace that will analyze the oil and tell you what the contaminate is. This is a new one on me. Let me know what you find at wd4ity@bellsouth.net , please.

Good Luck
Steve

I bought a 03 zx-636 that was laid down on the stator cover and bent the flywheel will the batt not charge if the stator and flywheel is rubbing the stator


Correct, the bike will not charge. Aside from that, if the flywheel is actually bent, and it sounds that it is, you will need a new crankshaft and probably a new stator. Without major repairs the bike will never run again. The crank will cost around $650 and the stator will cost around $330 and if the flywheel has been damaged ( it probably has been ) it will cost around $330 as well. The cost for the repair shop will be around $2000 to $3000. The bottom line is that you got taken by the guy who sold it to you. He knew full well the repairs would be far more than the bike was worth. Unless you can get a good engine from a salvage yard, you are pretty much hosed. Google motorcycle salvage kawasaki and see what you can find. I am sorry about the situation. Best of luck to you. Please rate my answer. Thanks.

My flywheel on my 01 sporty 1200c went out, do i need a brand new flywheel and do I need a spicific flywheel or could I use any flywheel?


If your flywheel went out, you've got major problems. You must have the correct flywheel for our bike. You cannot use a flywheel for an earlier model, it must be one designed for the Evo Sportster engine. Now, you can get a complete aftermarket flywheel from someone like S&S maybe. But, it still must be specifically for your bike.

I have a 1974 honda cb750 my first bike and i dont know nothing about bikes.it dose not run and the guy said the oil just drained out one night. anybody know what that means?


If it's a 4 cycle engine that doesn't mix oil with the gas (2 cycle engine), then I would say that there is an oil leak, a massive one, that needs to be repaired before trying to start and run it.

Maybe the oil pan got rusty or something. I don't know.

Good luck on the repair.

weak wires are sometimes the cause of loss of power,if they have been really hot from trying to start and become higher in resistance. looking at the ends of wires where connection are sometimes can reveal bluing of the copper inside (signs of heat). loose cable ends look good but dont perform well.Test charging system for proper charge output to voltage reg. and battery.Short tolerance to load under start conditions could be due to not being charged at high enough volts from charging system. (too many chicken lites or other stuff drawing current)

Duc Issues


if you have time to help that is. Can you put the MV Agusta F4's exhaust pipes on a Ducati 748 Could it be done? I love the MV's quad-exhaust system but really am not a fan of the MV's looks - I preffer the Ducati's looks. I can't choose whether to get a MV Agusta F4 (1000cc) bike or a Ducati 848 - I love the Duc's looks and the fact that it has approximately 849cc (its true 1000cc may be too much for me to handle - especially as an everyday ride!). If I had it my way I'd get the Duc and wack those MV pipes out back - oh and those 190mm rear tyres (just for looks!). In all seriousness I really want to know the following: 1. Which will be a more civilized tool; i.e. which will be better to live with everyday? 2. Which bike will be easier to learn on (yes I know they both have way over 800cc, but still I wouldn't mind your opinion on this!). (When I say learn I mean learn to ride on because I have a younger brother who can learn using my new bike.). 3. Which of these two bikes can carry a passenger (I actually haven't seen the bikes yet because they are on order and have not arrived yet.). I really want to be able to take someone on the back of my bike every now and then. 4. Last but not least, if I got a Ducati 848 can I get those exhaust pipes on it! Thanks guys for reading and taking the time answering my post (if you really can be bothered!) - but please be bothered! haha. Thanks so much again for all your help. ,In all seriousness? 1. What do you mean - how do you intend to use the bike, commuting, weekend riding? 2. Neither bike is suitable to learn on. You are in SA. Neither of these bikes are LAMS compliant. 3. Either, but they won't like or thank you for it. 4. No. The MV has 4 cylinders, the Ducati has 2,,,
