really goose there is absolutely no reason we cant organize a slightly different piston of our own, i have already drawn 3d models of the valve pockets etc,

can you please find out the cost of a run of 12 similar pistons if we provide all dimensional details
I'm all over it on Friday! I'll call them and let you know. Since we are awaiting confirmation from JBS anyway, I'm going to follow Bushy's lead and inquire as to what it would take to build out a custom piston of our own and what it would take "run" wise. In any event, the tally to date is: Goose 4 (maybe 5 if necessary); Bushie 2; Spanner 1 (THAT'S OVER THE HALF WAY MARK ALREADY) Huzzah!

I had also looked into the Wiseco pistons for Husaberg, as I saw they now list a piston for the BerG in their 2015 catalogue. The pistons are Build On Demand though, and same as for the 105mm, the minimum amount is 12 pistons.

I would also consider getting a 105mm piston if it will help to fill the order

the main information is in here

650 '700' kit do it yourself thread....

big piston valve pocket 3D model in the zip

piston volume -14.1cc, squish = headgasket thickness = 1.2mm

CR approx 12:1

valve pockets are same as 100mm 628 elko piston 39 and 35mm diameter should be just ok for up to 37/32mm valves and stock cam

more models with different valve pockets tomorrow


STP file of piston top with stock valve pockets

628 rod details http://husaberg.org/attachments/husa...ad-628-rod.pdf

STP file of piston top with pockets for 38/33 valves and big cam (kibblewhites)

http://husaberg.org/attachments/husa...er-pockets.zip

i suggest goose we ask for the one with big valve pockets to cover wider range

specs then are pin center to piston top 24.5mm

lower part of piston can be the same as a prox piston which they have at wiseco

PN# 01.6606.A

A: Diameter: 99.95mm

B: Total height: 41.20mm

C: Pin size: 20.00mm

D: Compression height: 14.50mm

G:Boss Space: 23.00mm

if they need a complete model of the piston lower half i can do it but im very very busy LOL
Thanks from WArdogG and tourist

liner outside dimensions in pdf for westwood

will need to spec ID final size at some point based on piston diam at a clearance of 1 thou per inch bore diam

also i recommend adding a groove on the top for a sealing wire ring and grooves on the od of the liner for beytter cooling

ill put these details up later but they are already uploaded in various locations on this site

the basic details required are all there we just need goose to take a big box of beer over to wiseco with some of his big pistons and liners and talk to the berg rider there

Bushie, the dish in my piston measures 7cc I think, 13.5)

if possible I would like the valve pockets only and to finish the dish myself

Once this job is done (2 weeks), I'm likely to do just that!

Just got off the phone with "Al" a Husaberg guy who looks forward to dealing with us. Price is pretty much the same depending on the attributes we want. The armor coating on the top bumps the price as does the skit coatings. Still, not substantially and I felt his representations about the top coating were sincere (substantially deflects heat from the piston and con-rod and becomes harder in the process) Anyway, since Wiseco used to make pistons for Husaberg, he's confident and JBS, he's confident that ours should be no trouble. I've attached the types of "options" wiseco provides for your review and discussion. Still, 12 piston minimum.
