My 89 has a K$N lunchbox, and was rejetted  by PO and I don't know what jets were used. I have a pipe thats getting welded on after the midpipe(is just like quiktaco's). What should be done to my carbs for the best performance?

I believe they come with a restrictor ring just for that application. Just toss the filter and the restrictor ring in the airbox and you're good to go...

I have a K&N drop in for sale if youre interested. The guy that wanted them never got back to me. I want a lunchbox thats why I asked.

I already got one, but thanks anyway.  What is this "lunchbox" that you speak of? Sounds tasty!

Replaces the airbox and drop-in filters.  From the information I've read, given the significant increase in airflow, you need to rejet (no restrictors are included with the lunchbox).

Anyone got a good site to buy some jets from?
