<< Hurycne, big bore? 703..760...,dual carbs...???? come on you can do it! It's just money! >>



Thats right!!! It is only money!! The root of all evil, so get rid of it while you got the chance!!

 

I got no wife, no money, just me and my quad (and a drum of fuel). What more could you ask for!!

 

Adam, nice pics on your website! OrganDonor you and Marky are too funny! Here is some useful info on the water pump seal replacment: Water pump seal info.... It's on the F650, but is good stuff.

 

Well since you guys aer on the topic of coolent I have a question. Every 6 rides or so my overflow tank in empty. I have checked the oil and no water and I cant find any leaky seals of gaskets I have just been filling it back up and riding. I was just wondering if you guys have any ideas on where the coolent could be going. The quad runs great and everytime I open the radiator after the quad cools down it is full to the top. I am at a loss.....anyone ???

 

DSaholic, maybe it's just evaporating? I assume you don't have any milky looking oil when you check your oil(dipstick)? Mine is leaking just a few drops right after the engine warms and the fan comes on.

 

GO FOR IT HURYCNE!! 760 no a 703, i will pitch in a 20.00 dollar bill. Any one else care to pitch it? Maybe you can be next.

 

Hey, thanks buttfungus. Always liked your site too, as a matter of fact, it's in my favorites for when I need some info! Hope to see you the 29th !

 

I was kinda thinking the same think. I guess I will keep a eye on my oil and not worry about it to much. thanks ....

 

Update, got my water pump seals replaced. Leak fixed! Went ahead and ordered a new waterpump shaft and 2 seals and o-ring for the waterpump housing. I replaced the shaft because it had some grooves cut into it and this article F650 Water Pump repair FAQ.. and some pictures that Thefasterthebetter sent me really made ths job easy.It wasn't that hard to do. Similar to replacing/changing clutch/springs. I think I was running too lean, causing it to run hot with the direct mount k&amp;n filter and mikuni 180 main. My leak showed up not too long after the carb mount filter/180 main jet combination. I am now going to try a 190 mikuni main, and some other sizes below that and will let you know how it goes. Anyway if anyone needs the pics/diagrams, or questions email away. Thanks to Mark and Jeff!

 

DSaholic, The head might have come slightly untorqued. What can happen is everytime you shut the motor down after the cooling system is hot and pressurized, small amounts of coolant can leak into the combustion chamber. On the next start, the coolant is flushed out the exhaust. I have seen this many, many times. I always use the level of the resivoir as an indication of my head being sealed.

You shouldn't have to add coolant to the resivoir every ride. The level in the resivoir should remain between the full and min levels week after week, assuming the cooling system was full to begin with.
