Spike Intake Assy
I put a D&M Custom version on my 04 Ridgeback and it looks bad ass. See Pics on my biker photos. It also helped the engine breathe better. I know this because when I was done putting it on, the RPM increased which meant the engine was running leaner because it was getting more air. So I guess it's not all show and no go. The one I have came with a K&N filter.
I looked at the auction on Ebay and that's a great price but I'm not sure who makes it. You will need a bracket to mount it on the carb. Otherwise you will put stress on the carb and manifold and you will have intake leaks. D&M makes the bracket for the S&S carbs. Take note of the shims provided with the bracket and shim the assembly so the head breather ports/bolts carry the weight of the intake and not the carb and manifold while still making sure the intake assembly seals to the carb. You will be removing the stock intake filter housing you will have to rearrange the crankcase breather hose. I brought mine from the crankcase to the intake bracket. The Big Dog dealer said it was unconventional but it's not a bad idea since it will pull a slight vacuum on the crankase. This arrangment also keeps the oil mist from getting all over everything. One last tip, put a small amount of red RTV on the shims and bolt heads to seal the mounting hardware. I didn't do this at first and had oil droplets running off othe bracket from the heads. Simple, but it's been working. Oh and don't over tighten the breather bolts, They are hollow and snap easily. Let me know if you need any other info or some close up pics.
