BenBB Posted November 19, 2003 Report Share Posted November 19, 2003 Yeah, I used a dremel with an orange (I think it's aluminum oxide) bell-shaped bit, a rattail file and a small thread file (triangular shaped). What you want is to smooth everything out on the inside, NOT f*ck with the rubberized stuff on the outside where the reeds close against. You want to leave at least 1/16" of area for the reed to contact. If you look at the stock cages, the casting itself has some sharp edges, and the black rubberized stuff extends into the inside. You want to take off the rubber (inside only), smooth all the castings out (don't polish it, you want a somewhat rough surface, don't use finer than 80 grit anything), and remove some material where the reeds shut (again, make sure there's at least 1/16" for the reeds to close against all the way around their edge). Don't knife edge the little arms either, make 'em round. As long as you don't take off too much around the reed seats or otherwise mess up the rubberized part where they shut, you should be fine. BTW I went one clip leaner on the needles after I did mine, and will be starting on my RZ cages pretty soon, if you need some pics lemme know.

BenBB Posted November 19, 2003 Report Share Posted November 19, 2003 I dunno for sure, but I know the price of porting them yourself vs. the Delta's worked for me. I think Scott M & Banchetta did some testing awhile back and the Delta's did better on the dyno (anyone else remember the specifics?). If you got the bucks go for the Delta's, not many people didn't like them, if not port the stockers and get some free hp. Quote Link to comment Share on other sites More sharing options...

Oilsmoke Posted November 20, 2003 Report Share Posted November 20, 2003 I was thinking of cutting out the center post. Has anybody tried this and what did you think of them. I am running full pedal TDR. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 20, 2003 Report Share Posted November 20, 2003 I have seen them with about half of the center cut out of them. Then the rest radiused. Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted November 21, 2003 Report Share Posted November 21, 2003 Told Ya I would do it this weekend Im not sure what to do towards the center where the rubber still is? Should I make the endges sharp or hone them out? Besides that how does it look so far? Im going to start on the other one now. Quote Link to comment Share on other sites More sharing options...
BenBB Posted November 21, 2003 Report Share Posted November 21, 2003 NICE job Justintoxicated, looks great (might want to see if you can blend that one spot in the top left opening where the dremel cut a little deep). Take off the rubber in those corners: I used a small thread file (triangular cross-section) and it worked great, those can be a sharp corner. Excellent work though, how long did it take ya?

Banchetta Posted November 22, 2003 Report Share Posted November 22, 2003 I only dynoed the stock cages vs. the ported cages. No gain, but no loss either....It didn't make any differences w/ the ported carbs either......I didn't dyno any Deltas, but wish I had some to dyno......maybe ported motors will have more results..

I blended it the best I could that was my biggest mistake Never done this before though...Let me get some pictures of the finished cages. I spent about 5 hours including removing them from the bike Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted November 22, 2003 Report Share Posted November 22, 2003 I think I messed up? Anything I can do Or do I need new cages now? looks like I gouged the rubber on the outside a bit, but the cam exadjurates it a littlle Other than that here they are, I hope I didnt screw it up too bad.

PassionRE Posted November 22, 2003 Report Share Posted November 22, 2003 I was digging around in my little black book and found Factory Yamaha Roadrace specs on RZ reed cages. Widen openings 1.5mm, Raise openings 4.5 mm and lower openings 4.5mm. All cuts should be at 16 degrees and corners should be at 5 mm radiuses...just a tid bit if your interested...Jim Quote Link to comment Share on other sites More sharing options...
