@Baileyboy2008 well like Calum pointed out there’s no such thing as pinning your valve half way if the valve is have way closed you will get zero power above 6k open her all the way and then see what it does

I did my mains recently and one of the seals was tight. I had to clean it up a bit with some really fine wet and dry, just to kinda deglaze it. Lite smear of grease on the seal and it went in easy. Don’t forget the right seal is one sided. It should have outer wrote on one side. Also it doesn’t go all the way in. It sits flush with the outer edge (or it does on mine 1988 3bn). It shouldn’t be a bear to fit cause it’s only the outer that’s touching anything, unless you left the spacer in the crank. You just need a longer tube to drift it...
