810

a brand new wiesco 810 kit arrived today, just had to tell somebody, but not anyone locally

I am waiting on mine now. Can't freaking wait!!

I'm waiting on a set of 810 Wiseco pistons myself

I am curious as to what the total estimated expenditure will be for upgrading to 810cc.
So, if the bike to start with is in perfect running order; is it just the kit and outsourcing the boring of the cylinders? Anything else hidden in there? I am wondering how much of the "extra" parts I have laying around here I need to sell...

base gasket, cam cover gasket(pricey) o rings on the top and base of the barrels, there is a couple of rthe oil restrictors and a couple on 2 of the studs. shave the head, i knocked 30 thou off mine just started cutting into the edge of the valve seat insert and apparently it realy wakes it up but i didnt have anything to compare it too beforehand, mine lifts the front wheel in first with just throttle in a very untuned state. look at a rejet and maybe some pipes.

The piston kit and boring the cylinders runs $591.00

I have most of what I need, down to bore job an time, and making a few decisions as to which cylinder head and carbs, got a few 650 heads and one 750 head, aftermarket cams around .400 lift and 284 dur or GPZs

Who's porting your cylinder head? Which one are you going to use the 650 or 750 head?

I don't know if I will port the head, I'm thinking about trying to keep some kind of mid range, if I use a 650 head the comp ratio will be higher, smaller ports and valves will keep the A/F speed up for a better mixture and a bit more mid range, the 750 head will give a bit lower compression and slower A/F speed, will sacrifice some mid range, a ported head may give more top end but might make it difficult to ride in traffic, I haven't really decided yet, but if I port one I will probably do it my self, just a basic port and pocket clean up, I have a bunch of cash in it now and I have a few other bikes(6) and a chevy

Just finished an 810 build myself. I chose to slightly port the stock head. Had valves refaced, with gpz cams up top. Should be a pretty potent little motor. I am still saving for my full dyna ignition before I can fire it up. I will let you know how she rides!
