Anyone running the BGM "12HP" top end on their P200?
Is there a noticeable improvement over the standard top end?
Not interested in kits, just a boost over standard. Have a SIP Road 2 fitted already.

That's a very good cylinder and piston. Actually it's shortened 0.7 mm and you don't have the stupid standard p200 gap between the piston crown and the cylinder head. Add to this cylinder the MMW cylinder head and it will be a perfect combo

Bit the bullet and got one, not too impressed with the finishing, especially the top transfer port, had to be cleaned up quite a bit as did the entry into the barrel which needed opening and squared off. The ports on the piston were rough as f**k, so tidied those up too. Anyway, the rest was fine so fitted and started running in before VWD up the road in Belfast this year. Will report back with findings.
