Can anyone please help me with the jetting on the AMAL GP2 for my Silverstone RDS? The engine has been refurbished by Simon at Nametab and he looked-up the following: Main 420, Pilot 25 & Needle 109.
I have taken the existing main jet out which came with the bike to find it is a 320! I called AMAL (Burlen Ltd) and they say the original main jet for the Silverstone is a 350 – they did agree the Pilot & Needle at 25 & 109 respectively.
Obviously I don’t want to risk seizing the new motor but I don’t want to run it over-rich either. Can anyone running a GP2 in a Silverstone please give a sense-check? It will have an exhaust made by Andy Bacon and silenced to 105db for CRMC parading.
Also struggling to find paper manifold gasket at 1 3/8” – who may be able to supply?
