Will this work to fix my gas problem in my poorly wintered motorcycle?

I have about 1/5th of a tank of gas that I left in my 2000 Suzuki SV-650 S tank over 3 months of winter in a heated garage. If I use starting fluid in my carb, get the bike running, run the bad gas out. Then fill up with good new gas and use a fuel additive for carb treatment. Is this a good idea, or should I just suck it up and take it in to a dealer and let them deal with it? Thanks for any help.Oh by the way, it won't start now, it will turn over fine, but wont'actually start. If anyone can give me a step by step procedure that works I would love it. Also, I've had Sea Foam reccomended to me. Anyone heard of it?

yeah you can do that. it will be fine.

there is an additive for that it restores old gas ..

Starting fluid in small egines tends to eat away at the seals. My bike sat in an unheated garage all winter, I put some fresh gas in it and it started right up.(no winterizing additives)

tell u what i dont think any of that will make any difference..it has sat 4 ..3 mths in a heated garage,fir it up and drive 3mths is nothing 4 gas 2 sit and b usedand if ur tank is still off dump the gas and refuel and u'll b great 2go...adios..

If you feel comfortable in doing so open up the carb and clean it cause gas will caramelize over time and gunk up the carb
