[jcsnook]

thank you jim quick and no messing about as usuall got my ups info and i will be watching the tracking
thanks mate !

Gary, I mailed it USPS (United States Postal Service), not UPS.  Much cheaper that way...

Just so you know where to check the tracking.

arnt they the same firm ?
i got an email with tracking and everything on there
if anything like last time i will have them in a week  ish
DHL seem to have the best and quickest service
i had something from china sent and i had it in my hands deliverd in 36 hours !
but they are not cheap

No, UPS is United Parcel Service - Privately run.  USPS is Govt run.  Hard to believe that they are cheaper, but wow...WAY cheaper!

Awesome Andrew!!  That worked out great!  Happy to help where I can...paying it forward as it were.  The help I've received on this forum for my 3XV project is more then repayment for these efforts.

If anyone else needs them, more can be ordered at any time.

got anymore jim ?
ive done it again !
only need 1 more again its the other one that went this time
so still got a new one but want to rebuild it with 2 new ones and get them both plated to suit them !
so have you got one please ?

Tough break Gary 

Don't really have any spares, I only have the pair for myself left.  I can order one from Wossner for you, and whatever they charge me for one piston, I will charge you.

I won't make you wait for it, I can send you one of mine, I just don't want to get caught like I did on the first order.  I sold my pair that I got for the bulk purchase price, only to replace them at a higher cost because of a price increase and a smaller order.

PM me and I'll let you know what Wossner says after I email them on Monday.  Hell...I may as well order a few extra sets and either have them on hand t sell, or sell them eBay.

thanks jim let me know the price please ?

Ja Jim
I'll be installing my rebuilt Wossner motor in a months time.
If all goes well ill order 4 more and sell my oem spare pistons on eBay.
Don't want to mislead you as its not a promise but its almost certain.

At the risk of sounding negative,(and i really don't want to be)i wouldn't recommend using the Wossners for racing,they seem to scuff quite easily under racing conditions.
after running them in, i checked the top end,both pistons were slightly scuffed in various places,as were both cylinders,so i removed the scuff marks/high spots from the pistons,and had both cylinders honed out,and had the clearances checked.
this has happened on 3 occasions now,first time after running in,the other 2 after race meetings.
one of the pistons even had a slight smear up against the lower ring,trapping the ring in its groove(partial seize?)
FWIW,i was running super unleaded with Silkolene Pro 2 @30:1,B9EV plugs,both mains were on the rich side,everything came out nice and oily on stripdown.
 

[Paul]

Hmmmm
Maybe too soft and alloy not mixed well? Expanding erratically?
Are you running a thermostat?
I will do a strip down after run in and put findings here. I have only started my bike. Not finished yet.

pics of r/h piston & piston pin,the pin was way too tight,had to hammer it out,not good...

[maccas]

Ey up Ian,

What bore clearance were you running them at?

Just out of interest.

Dan

[Kingy38]

same bore clearance as when i ran the stock pistons(got it written down somewhere!)
l/h piston pin came out nice & easy,so why would the r/h side take so much effort to remove? 

[Warwick]

Are you still running the one sleeved cyl, Ian?
