    Ever figure out Lean condition with 4in. intake

    Guys I know that with a Stg II Ski everyhing is ok as far as being lean. Well did we ever have anyone do a test with bigger and better air intake. Like the 4in. If so, was it OK?

    Well I have the RRIC instead of the Riva, so I am just tring to find out if it is safe. I did a search and found that the STG. II was good, but did have issues in extem cold and someone mentioned 4in intakes and open air Riva tubes.
    So I was just asking as I have a 4in intake and wanted to know. Never any high temp alarms are anything.


    Oh a RXPblast my 4in compared to my Riva was 100RPM improvement and hits it hard.

    Please let me know...

    I actually bought the Rectifier bracket and SCer 4in adapter from Justin.
    Do a search on them and you can PM him to get it on order. Then I bought 4in hose and ran it from the SCer to the Fresh air intake tube in front of the seat. It has a lot more fresh air to the SCer. Big Improvement IMO.


    Anymore thoughts on the 4in and being lean W/ Riva STG II.?

    ill take some pics of mine this weekend. HUGE improvement over riva power filter and especially stock. all in all would cost about 100-150 depending on what filter u buy..ect. i can install one in like 40 minutes..lol

    i personally left the stock air box in place, kept the rectifier in place, and used the air box as an oil catch can. pretty creative idea if i might say so myself . its less crap u gotta buy.
