Carb advice on a '92 GSX1100G
My bike has the Mikuni BST36 CV carbs. I redid them last year by taking them apart & using a sonic cleaner with Pine Sol and hot water. I found one of the plastic slide guides had cracked, so I replaced all 4 from a site that had 2 variations listed, but only had 1 type in stock. Used new carb kits and replaced the o-rings on the carb boots. The bike ran great for a few weeks and then it acted like it was only running on a couple of cylinders at lower RPM but runs good at full throttle. The idle is also erratic, it dies out when cold and idles faster than normal after a ride.
I'm looking at what options are available. The fact is my carbs are almost 30 years old, so I would not mind putting something new on, but it doesn't look like anyone makes CV carbs anymore. I've reed also that these carbs have problems with needles and emulsion tubes. Mikuni has the RS series that are available in the correct spacing. I've read a few threads here, and it appears the CV carbs are a better fir for street use. I see the FCR Keihins are highly regarded, but they are also highly priced, well beyond my budget.
I'm looking for advice on my options here. I would not mind shipping them off for a professional rebuild, as I'm sure that would be less costly than new carbs. I'm also not looking for mega-power, I commute to work on it on good days to save gas.
