Question about 2007 Gas Gas EC 200 Hobby

Engine overhual Well winter is just around the corner here in chicagoland and after fixing up my bike cosmetically I'm ready to dig into the engine. I bought my 03 200 last spring and this is my first two stroke. I have done all the easy stuff like change all fluids regrease etc. When I bought the bike it said it had a new top end but I doubt that by the condition the fluids were in when they were changed. I was wondering how to tell when the bike is due for a new top end

Clutch not working

Hi Inge, not to worry steel plates got a little rust film from sitting probably. Let the bike warm up for a few minutes then do the push,run, jump on the seat routine while in nuetral and drop it in 1st gear and drive it around for a while the plates will eventually break free and peace on earth and good will to all mankind will prevail. Try using 20w50 Harley Davidson SYN 3 in the primary and next winter don't put the bike in storage with the engine hot. Wait untill the next day and fire it up drop it in gear for 30 seconds then put it away for winter storage. Good luck

How to store your motorcycle for winter. Storing your motorcycle.

As the summer months start to come in, we all like to get our motorcycles out and start riding them, but i hear a lot of people saying help, my bike wont start! That is because when you last parked it in the shed for the start of winter, then you made no preparations. With a few simple steps, next summer, you can get your bike out, and fire it up without any problems, ready to ride. There are things you must do when you go into storage, and a few things to do when you bring your bike out.
OK,so winter is approaching, and you want to put your bike away in the shed.
First thing you need to do is drain some fluids. Drain your engine oil. Then drain your gas tank and carburetors. It is important to drain the carbys, as the fuel left in the float bowl will go bad. You can choose to totally drain your gas tank, or fill it to the top with gas. Storing a tank full with gas, leaves no room for moisture to form, causing rust on the inside of steel tanks. Next, you need to also disconnect one lead from your battery, or even better, if you have a trickle charger hooked up to it. Thats about it really. Also,if you are confident in doing so, remove spark plug, or plugs, and spray some penetrating oil down into each cylinder, turn engine over to work it through. This will prevent any moisture or corrosion from forming on the inside of your cylinders. It is also a good idea to clean or replace your spark plugs each year anyway.
Now it's summer, and you want to ride, just roll your bike out. Put in some fresh engine oil, a fresh tank of gas, and a fully charged battery, you are ready to go!

Is it expensive to fix this bike up

Cost is always a relative thing. Someone who really wants to restore a TX750 will spend a lot more money refurbishing a motorcycle than someone who's just looking for a cool older bike to ride around town. All that said, Yamaha reused many parts like brake calipers and rotors across multiple motorcycle models, so anything other than cosmetic parts are more or less available--sometimes from a dealer, sometimes from Internet sellers of old NOS parts. Cosmetic parts, such as tanks, side panels, and seat pans (nevermind seat covers) will be a lot harder to find and more expensive, though you can sometimes find used parts without having to pay an arm and a leg.

The real question of cost depends on what the bike needs to become functional. Unless it was stored dry, it certainly will need to have the carbs soaked and cleaned out. That's labor-intensive, so it will cost money if you want someone else to do it, but it's also something you can do yourself. Brake pads, tires, and a new chain can add up to a fair chunk of change, but these fungible items are what they are. For me, the biggest question is the engine itself. If the engine has good compression, it might not need more than a valve adjustment and tuneup (new points and condenser might be a good idea if the bike has been sitting for a long time). On the other hand, if you have to get into the engine, even to do something like replace head and barrel gaskets that have become brittle from old age, you're looking at a fair amount of labor for a bike that's not considered all that collectible in the grand scheme of things.

Bottom line: make a list of all the things that the particular bike you're looking at will need to have done to return it to the condition in which you'd like to have it. Price out the cost of the parts, then think about how much of the work you'll be able to do yourself. My guess is that you'll have a "gut feeling" about the bike by the time you price out your parts. That process gives you a good sense of the amount of labor that will be required, too.

Hi, is this after the bike has been away for the winter, these bikes Are designed to run on modern fuels, the intruder normaly runs fine , good advice would be to replace the spark plugs and drain the fuel from the carburettor float bowls by undoing the drain screws in the bottom of each carb, prior to using the bike after the winter, you may also check the condition of the air filter located on the left hand side of the engine under the chrome cover

Bike not firing properly, plugs fouled

If you used the choke to start the bike last winter, you probably fouled the plugs. Depending on the age of the plugs, you can either clean and re-gap them or replace them with new, which also have to be checked for gap.
Secondly, if you did not run the bike out of fuel after starting it, chances are you have some build up in the carb jets. New, clean fuel and Techron or Seafoam gas treatment will help if it's not too bad. Follow directions on the can. I personally used Seafoam but Techron is recommended by Honda. Be sure to mix per instructions, which on Seafoam is 1 oz. per gal.

yes you should start it at least once weekly to maintain battery and keep engine lubricated, also it keeps fuel flowing through the bike. but dont just start up then switch off, make sure you get it up to normal operating temprature, this keeps moisture out of the engine oil.
