Hi i recently just got an 87 zilla and ive always owned the 250 and i have a few q's about the 500 like how much compression is normal it has 140 psi right know and the head gasker leaks a little is there a no blow gasket i can get for it oh and its definetly faster than my 00 ds650

 

Congrats, i allways wanted a 500r do you got any pics??

 

congrats I wish you luck

 

ewll i blew it up due to a blown head gasket and i took it apart and its on its last bore 3mm over and i was wondering if theres a company that sells a bigger piston like a bog bore piston for the stock sleeve and if not where can i find a fair priced big bore kit
