Dynojet for GS750E 1982

[CRGS]

Hello good people,

Recently I bought my 750E 1982. It came with the V&H 4to1. I changed the air filter to use K&N with the stock air box. Jets are stock, I must have to change the main jets correct?
I was thinking on these Dynojet. But I see two different SKU 3102 (in stock) and 3315 (out of stock). Do you know the difference?



Thank you in advance

If you're going for a Dynojet kit then it's 3102 for stage 1 set up you have.

What are these stages? I saw another post talking about stage 3
Thanks

From their website:

The stage 1 kit is intended for motorcycles / ATV's with a stock engine using the stock airbox, air filter and stock pipe. Stage 1 kits are fully adjustable to allow the use of a well designed aftermarket pipes and stock replacement air filters like K&N.Stage 1 kits are designed to improve throttle response and driveability and in most cases power increases of approximately 5% throughout the entire power range can be achieved.

The stage 3 kit is intended for motorcycles with stock or mildly tuned engines using a well designed aftermarket pipe and individual air filters. In most cases power increases of 10-15% can be achieved. However driveability may be compromised particularly with short stroke, high rpm motors.On some modern engine and airbox designs, individual filters and proper jetting offer no performance improvement yet compromise driveability, in such cases stage 3 kits are not available.
