Anyone tried GasBike case induction GT90 kit?

look for a 15 x 27 x 7mm double lip oil seal. nitrile is the standard material, but viton has a better temperature range and will be less prone to blowing out. viton is more expensive however, typically somewhere around 6 times the price. any double lip seal will be an upgrade over the stock ones, so don't worry too much about viton if you can't drop $40 on seals

Thank you...Much appreciated

Got one of these kits and when I swapped my internals, my piston is very far away form the head at tdc. Is my rod/piston not the right size?
