First off hello and welcome to the forum.

Secondly and most important. you have now ensured that you need to pull the engine and replace the water pump mechanical and oil seal. By using the stop leak you have blocked the outlet for the leaking pump seal and it will be pushing the water past the oils seal and into the engine. Next you will see the milky oil in the engine. Get that fixed right away.



As for the carbs it's just a matter of pulling them apart and doing a proper cleaning. They are probably plugged up with gummed up old gas that has them running rich. It's a must with a bike that's sat for a long time.

LRCXed, thanks for the welcome, ok this sucks! thought i was doing a favor to myself by the stop leak pellets, bummer. i just needed to buy some time for a few weeks till money came in. Been loving riding again been a few yrs. yes found carb rebuild kits 24.00 each side can't remember site have it book marked. Now for the mechanical seal from what i am told is what is leaking i put about 200 miles on the bike in the last week or so and no over heating how hard is this to do? do i have to remove engine from bike? Honda says it is a 6hr job about 200 for the parts so if i went that route i would be spending around 900.00 so doing it myself is next up. i work on all my own vehicles so i say a bike is just smaller and hopefully easier lol thanks what kinda bike do you have and what have you done to it.

For the in-bike mech seal you just remove the carbs and take the Water pump cover off.Pretty easy once you get conversant with the bike/engine.

Shep thanks for the info, when i pull the rear cover off do i need to drop the rear of the engine done some, and while in there will i be able to access the timing chain to adjust it if necessary. just got home from work a while ago and have not looked at that online manual yet but you seem to know alot about this so i figured i would ask. Hitting the bed hopefully i am tired. thanks for the help
