Remove and replace them with sealing tape for hot water lines. Be sure to replace any lost coolant.

SOURCE: won't start leaks gas and oil

Maybe try changing the float. It may be filling with gas which means it can't float.

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!

Coolant leak in Cylinider

You have to have a torque wrench to start with. Without it you are wasting your time. You can also damage the head. You can buy a torque wrench at Harbor Freight for a very good price with a lifetime warranty. I would not attempt to do it again without the torque wrench. You also might want to have the head resurfaced at the machine shop. Aluminum tends to warp when over heated. I hope this was helpful. Good luck.

Bike running rough at lower revs

If the bike sat without being used over the winter It could be bad gas. if gas sits without being used for an extended period of time it destabilizes and gums up carborators and fuel injectors, you need to add a fuel stabilizer to gas when storing for winter. To fix the problem the gas has to be drained from tank, then refil with fresh gas and appropriate amount of carborator/fuel injector cleaner/treatment. Then start the bike and let it run it should clean itself out and start running smooth. If bike did not sit unused for winter its possible they installed the wrong plugs sometimes they talk you into spending more money on platinum or split fire/gimmick plugs (always use the exact same plug that came in the bike when it was new!!!!!)

If your car has a sunroof, one if the sunroof drains runs down through windshield post down through to bottom of the car. If it gets plugged it will back up into car. If it's coolant you're finding (sticky and smelling like coolant) your heater core is leaking

I've got a 08 r6 thats done 3,700 km with a small coolant leak behind the what I think is the water pump housing. Is it a common problem and any ideas on how to fix it? And cost?

Most Yamaha water pumps have a weep hole that drains off any leakage that migrates into the space between the oil seal on the shaft bearing, and the coolant seal at the impellor.
This prevents the fluids contaminating each other.
Sometimes a seal will leak after sitting dormant (winter storage) for months...and they will seal again after a few rides.
Don't be tempted to plug off the weep hole or crankcase contamination can occur.
Not real familiar with your model...but the bigger touring bike (Venture) the seal can be replaced along with case gaskets for around $60 in parts.

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.

My Anitfreeze leak

Have you checked to see if your bike is building pressure in the radiator? I suspect you may have a blown or leaking head gasket. How many miles do you have on the bike?
Have you drained the coolant and noticed any discoloration? This won't always happen because the system is being "positively charged" which means it may be just getting cylinder pressure.
Those "special purpose plugs" are designed to be a "safety" plug meaning they will blow, leak or seep if the cooling system becomes pressurized from a leaking head gasket. They save the engine but are a pain because the head gasket is not fun to replace.

Winter storage solution for a 2008 Yamaha Royal Star Tour Deluxe

you can take out the plugs - inject a little engine oil, crank the engine 5-6 times and reinstall, support the bike so the weight is off the tires, drain the gas and spray the tank with a rust preventative....

Winter storage

If your brake fluid is in need of changing, do so before long-term storage. Similarly, hydraulic clutch fluid should be changed before you store your bike; both systems may suffer failure if moisture gets in. Also make sure your coolant is fresh, as deposits can form from old fluid. For service intervals, consult your owner's manual.
