Why cant i let my blaster go?

my brother gave me the best gift ever when he moved to florida he left me his yamaha blaster, its top end was blown and a million other things were wronge with it.. basicaly everything. i took every part of it off and rebuilt it plus a couple minor mods. like painting different parts and i put a new pipe and silencer on it and an oil block off kit and so on.. idk i seem to have a problem with it once ever 2 weeks... now that im down to the last stretch of it being restored (new plastics and such) well anyway i finaly got it going nice and the last thing i need to do is put new brake pads on it. anyway after all this was complete my plan was to buy something newer bigger nicer and so on. BUT i just cant let it go i want sumthing better but i cant let her go its weird its like i have a bond with it... its totaly moddable but idk should i dump money into it til its as fast as i want or is there another option.. i feel like its a part of me i mean i only put like $700 into restoring it.
