Jetting on LC RD hybrid

[mavguy]

I am running a 350LC top end , with a 5mm spacer on RD350 LC long rod bottom end with stock exhaust.

my question is what changes do I need to make for the timing which is 1.8 for RD and also I read somewhere that the 81 LC uses 200 main jets in stock form while the RD  jets on the the VM 28 are 140mm. Do in need to change the main jets then? Thx!

what jet tubes and airfilters? that is what really matters

[mavguy]

Not sure about the jet tube but I think they are the stock size.The air filer is clamp on K&N on the Y boot.

stock.. for an aircooled 350? LC 350? this stuff all matters. Before oyu go any further, you need to know what jet tube, carb body, needle etc thats in there.

Stock VM 28 specs for RD350.

then you'll be in the 220-240 main jet range as a start.

Right.thanks.what about the timing settings? Since I am using the RD400 con rods with a spacer underneath the cylinders.
