I just finished Reassembling the top end on my 400ex. I did everything to it the engine, stage 2 hot cam, 440 11:1, ported the head, 38mm Lectron carb and to top it all off, a LRD Pro 4 exhaust system. Man the quad hauls, its pulls much harder than a raptor and its still running REALLY rich.
The downside is i didnt realize the LRD Pro 4 exhaust was going to be as loud as it is. I mean, it sounds like a harley at idle, and at full i cannot imagine what it will do. It is much louder sounding than than i have read. Reviews have said that its only about 95dbs @ 4000, my guess is its closer to 110 @ idle.
Does anyone know where I can find the spark arrestor insert for the LRD Pro 4 exhaust? Also, just out of theory, but i think the main reason for such high sound out put at this point in time is not actually the pipes fault. I think that since it is soo rich, i am not combusting all the fuel in teh cylinder efficiently and it is sending unburnt fuel particles into trhe exhaust where they are exploding, giving it such a loud raspy exhaust note. Does this make since as the possible explaination?
Thanks,
Greg
