According to the previous owner of my sled it is completely stock. It is the zx chassis and has DPM. I recently pulled the carbs to put in rage cages and see that it has 380 main jets. I've read on this site that they had 400 mains from the factory. Some documentation at the dealer says 400 and some says 380. Is there someone who has owned one from new that can support either of these findings? I have read Optimizing your 600HO by TT670 but I believe that is for the REV chassis. What I need to find is the thread called Optimizing your ZX 600HO. Thanks
