http://www.ebay.com/itm/221550469589?ssPageName=ST RK:MESELX:IT&_trksid=p3984.m1555.l2649 Above is a link to a set of 05 1200 rocker boxes. I am wondering if converting to these would be similar to converting to a set of xb boxes. The reason I ask is that I own these currently and would rather not sell them if I can use them. | ||

Yes and no. They do eliminate a gasket, but as they sit they do not change the crankcase breathing. You can, however, drill a hole in the appropriate area of each top and add the XB grommet and PCV valve to do the same thing. They are much cheaper used though, as last I looked the PCV valves alone were like $30/ea. the last two pair I bought used were $10 shipped. | ||

Here is a list of the parts required to do the conversion. The prices are what I paid in 2011. I bought a replacement PCV valve recently and it cost $30 as Phelan mentions. 17605-00YB FRT ROCKER $39 17642-02A RR ROCKER $39 17353-89C GASKETS(2) $6.59 17358-84B GASKETS(2) $2.39 17606-00YA GROMMETS(2) $2.95 17607-00Y TURRET VALVE(2) $9.50 63858-49 GASKETS(8) $1.00 868A SCREWS(2) $4.00 You don't need the FRT and RR rocker covers as you have the Sportster parts. But you need to drill holes for the PCVs. Barry Hollister, CA | ||

Thanks that works for me. Where should I drill the holes? There are 2 breather valve looking things that have like this cloth filter inside should I get rid of it or keep it. I know the swap is to stop puking of oil but my question is besides slight design difference whats the fact as to why it works. Couldn't I just drill a pcv into the stock rb. | ||

http://thex1files.com/ Probably one of my favorite sites. I ran into a snare. I heard some say to remove the spacers and some say drill out the butterfly holes. I decided to sell these rocker boxes and covers and buy the xb ones. | ||

It is one of the "BEST" PRODUCT IMPROVEMENTS that you can make !!! | ||

Eeh for the price they are asking I don't mind piecing it together. just picked up a new front cover today and starting making a catch can as well so I have roughly 1 tenth of the supplies. | ||

Is it easy to make a catch can? I have a set of XB covers just haven't looked into all that entails with the swap | ||

It was a rear shock res for a 94 suzuki 750 that was in a fire so there was no re building. I wish I had pics of before basically instead of rusty it was all crusty so I scrubbed it for ever then painted it. The filter is secured with RTV but I am confident it will hold and it is replaceable as necessary. Going to put a drain plug in the bottom and I also need to take a trip to the plumbing store and find a hose bib fitting that will thread into the intake.  | ||

I Think I need to put the filter on a 90 as well. we shall see. | ||
