DONT SELL Your Beautifull 907IE !!!!!! Its very big pitty, if You do so...
U have good bike and U must think, that its MUCH more expensive(also), than Your 900SS after some years.... There are sooo many 900SS, that its "nothing" compared to 907IE, no matter, its lighter... THINK, THINK....!!!! Dont You have banks in USA ???? Go to bank and ask money..... Banks are full of money. If U have work, then its easy to pay moneys back little by little. I have taught, that there are plenty of rich people in USA and seems, that motorbikes are not so expensive there compared to "old world"(EU area)... 
Btw, surely i check already Your bikes in gallery and they look GREAT! :thumbup:
But if U sell Your bike, then do such deal, that if "need" then U can buy back that 907 to Yourself.. It can be written to papers....
Once again, thanks! :thumbup: You are the only one making me think twice about this!
Anyway I would still have the 900ss which since it's a 1991 is not a very common bike either and for the mountain twisty roads is perfect! thanks!
