big bore - reliability?

I think the cooling issue is much more a question of how hot it gets when you ride- there is a guy that owns the best machine shop in town that rides a supercharged 1428 Z1 based motor- and has no overheating issues and never has had over heating issues- even when he rides on 75 degree days, and idles in traffic.

75d degree days are few and far between in Texas, motors running hot is always a big concern around here, most of the time its in the upper 90s and traffic plays hell.
some dont like them but I like to use oil coolers to help with the heat.

ya, true dat- however- there are lots of northern regions with even more mild summers than we have. Anchorage just doesn't normally have extremes either way- we are too close to the ocean, like on it.

just buy the kit from kzzone.
i'm sure jay will be more than happy to sell it to you and from what i hear of him, he is a stand up guy and will offer you advice after the sale.
this is what he does for a living so if he says overheating is not an issue, i would believe him.
his shop has built more motors than probally half of us so i'm pretty sure he has a knack for it.


75 degrees?
hell, it stays that warm at night if not hotter here!
nothing like an air cooled black bike in 95 degree weather wearing leather and a black helmet on a bright sunny day.
( man i really need a mesh jacket )
