I have just recently installed a Hpd pipe/ Silencer, Clutch kit, Overbored carb and Rad Valve. I am concerned now about the amount of oil that the injection is feeding. It is apparently working but I see absolutley NO SMOKE behind me. I am using the Polaris "Gold" injection oil. If I remember correctly, I increased my jetting to 30 pilot and 280 main and it is pretty accurate.

Are these injectors adjustable?

How much should it be injecting?

 

The no smoke issue is why I dont like the gold.I run the regular Polaris 2stroke oil.
On adjusting the oil pump your manual goes into it real good.You can bump it up some but best to adjust it to where it is suposed to be set at.

 

It would smoke a little every now and then stock but it seems like it has absolutley none now.

 

This link should help you or anyone else who does not have their manual handy.
