My 1990 Suzuki Katana has a crack in the housing causing it to leak oil. What can I do to fix this?

You will need to remove the float bowl. Some carburators will have a carbon coated plastic float, if the coating gets scratched, the float will sink, causing your problem. If it's a hollow metallic float, it can get a hole in it, and sink. If the float is good, then the rubber seal that the float pushes up when the float bowl starts to fill with gas is leaking. This can be caused by debris between the valve seat and the valve, or the rubber is cracked or hardened. In any case, usually there is 4 screws on the rounded bottom of the carburators, remove them and you will see the float. If it doesn't float in a bowl of gasoline, it needs repaired or replaced. If the small rubber seal the float moves is cracked or deformed, it needs replaced. There may just be a tiny bit of debris between the float valve and the seat that needs removed. Good luck. None of this is very expensive.

go on line and type in welding plastics and there are plenty of pages on how to weld up the crack and how to reinforce the crack to stop it from breaking again

Milky looking oil is nearly always water, this is usually caused by a blown head gasket.

Replace with good used, straighten to the original shape or order new from eBay, or thefind.com

check fluid level. if low it will shift hard. also fix leak. could be a pan gasket or a cracked housing

hi what you have just described is the head gasket leaking.you say you do not get a drip on the floor??check to see if the oil has travelled towards the rear of the head??if so how much??although this will not really affect the bike under normal riding it is recommended that you get it repaired sooner rather then later.

asda sells cheap tacos made by discovery there quite nice with sour cream

check ebay or local suzuki dealer

The only reason to change it would be an oil leak you can't fix. Keep the oil reasonably clean and there should be no problems.
