that actually makes the cost about equal
Yes, chem dip eats rubber parts, as does carb cleaner, but you're supposed to get all those out of the carb before dipping it
Chem dip was around long before Yamalube, and has had a good rep since before I was born, so since that's what I was raised with, that's what I use
I've only heard 2 people talk about yamalube, so i'm leary of it, but that's not a surprise, as I also don't fully trust Hydrogen peroxide
it doesn't sting, so how can it be lethal to germs
That's probably why I don't trust the yam stuff 'it doesn't eat rubber, how can it be lethal to varnish'
Maybe I should be more open minded and give it a try, once my Chem dip is no longer good
I can always use the Chem Dip can to store / use the yamalube stuff  

ok one other question, if my breather box had a lot of fuel in it, i saw somewhere that said i may have fuel in the engine case, if so how do i confirm that and if so does it need to come out. also best way to do that. thanks. big learning curve. but having a lot of fun with this little bike. and for some reason i cant get my pictures to load up. i want to show her to yall.

If you have the stock vacuum petcock....and had fuel in the air box - that is an indication that your petcock diaphragm is leaking and letting fuel flow down the vacuum line.  The fuel then can either enter the air box, or enter the intake valve and flow past the rings into the crankcase (or both).

You can look at the oil level and see if it is too high, you can take the oil fill cap off and smell for gas - or for $ 6.00 you can drain it out and put in 2 quarts of Rotella T and not have to worry about it.

You should also do something about your petcock....either rebuild the stock one if you like the vacuum petcock and the potential problems that go with it.......or put on a genuine Yamaha Raptor Petcock.  If you buy  a Raptor be careful not to buy the Chinese copies - look for the white Yamaha box and the part number  5LP-24500-01-00.  If the seller doesn't state that it is a genuine Yamaha part...find somebody else to buy it from.
