Cheers ruby,
I dont actually know how to ride a road bike and dont intend on learning any time soon, we're actualy harvesting an R6 engine and using it in a "go cart" (think of something similar to formula ford), so lots of things need to be redesigned. i'm looking into the exhaust atm and because of its positioning/competition rules it needs to be drasticaly changed from stock. I was under the impression that the 05 and 06 engines were the same, but the purchase order went out today and we are getting an 05. I was going to head down to a bike shop if this fell through, but i'll cross that bridge when the time comes
As far as the muffler goes its not exactaly 110 dBA max its under particular test conditions that have a few loop holes like pointing the muffler tip up so that sound isn't directed at the mic, other competitors were using stock honda mufflers last year we just made one from scratch. In an attempt to reduce weight and get more air flow i'm looking into off the shelf/aftermarket/oem products that we could adapt... so perhaps the better question is, do you have an old muffler or 2 you want to sell cheap? =P
thanks again
