2000 SV650 - Whats it worth?

Hi, looking for advice on the value of my winter ride, it has to go - need a new combi boiler!!!!!
It is a 2000 W reg SV 650, it is the naked model, has original round chrome clocks, I converted the headlight to twins, it has Micron headers and a viper high level can, the carbs have been dyno-jetted and slides drilled, it has a K&N Filter. comes with a set of standard carbs, std air filter - de snorkelled, standard exhaust and front pipes. Had to fit new battery when headlights converted, has a spare regulator - changed this then changed the battery, it has a carbon vented front mudguard finished in yellow. It has renthall bars. The bike is yellow - candy apple type paint - not original but pro paint job. Wheels are yellow with polished rims. Bike is very very loud but goes a lot better than standard. Its covered about 19-20k. It needs a new rear tyure but I will probably change this and put a 12 month mot on it. It was serviced about 1k ago with new oil, filter & plugs. This is when the new K&N and moddified carbs were fitted. Would post pics if i could get it back from my brother who borrowed it and has yet to return it!
Also selling my other bikes (1996 ZXR600, 2005 Yam R1) but this is the only V twin.

Advice welcome or if interested send me a PM
