Brown shells (pair) 13316-333-003 for 400/4

[Matt_Harrington]

I would like to test my theory and see if the brown shells are what I need for my engine build.
If anyone has a pair I can 'borrow' (or buy) then I will add a set to my order from Webike.
(The shells will be assembled with plastigauge and not run!!)

You can get those shells from Japan >>https://www.yamiya750.com/index.php?main_page=product_info&cPath=179_273_206_209&products_id=2844

You test with Plastigauge and run in on Graphogen with new shells

Yes, I am aware of the firm (about the same price from Webike as well) but it amounts to the same cost as Silvers for just one pair and then is my choice correct? Hence my request.
I may just buy the whole lot from Japan....
