Great source of information is on Paul's Nighthawk Info Page(s): http://www.hondanighthawks.net/repair.htm Carb info is about half-way down the page. http://www.hondanighthawks.net/carbhelp.htm Have you heard us go on about the miraculous "Sea Foam"? Good with vodka, to clean your shorts (skid marks - be sure to rinse out well)!, kills ants and rodents, and, oh yeah, great for getting the gunk out of fuel systems. General opinion is that if Seafoam doesn't get it, then a carb removal and cleaning the passages is in your (immediate) future.
My opinion, especially for 25 year old bikes: "If it ain't broke, don't fix it!" As in don't disturb any more than necessary, unless you're a purist! (With lots of money!) Helm is a great source for manuals including copies of the original Owners Manual, Honda Repair Manuals, etc. http://www.helminc.com/helm/search_service_owner.asp?Style=helm&class%5F2=AHC Hope you have a good go with the repairs. A good tip for removing the carbs is to loosen the air cleaner mounting, slide it to the rear as much as possible and use a heat gun or hair dryer to soften the rubber/plastic connection between the air cleaner and carbs. Most helpful for reassembly.

Everyone on this site has been a big help to me getting my '85 650 in shape again. Do you know where I can get instructions or a manual on how to rebuild the carburetors? I let my 650 sit too long and it is running rough. I tried gas additives/treatments etc. Should I be using a higher grade gas?
