[QUOTE="Spokes574, post: 1324056, member: 22918"] Rich, I got the answers about the pipe from the manufacturer today: Pre/Post dyno curve is based on using stock fuel mapping! No need to alter fuel map to get good performance results. PIM piggy back onto original ECU box is targeted Feb. release will give approx. 1-2hp gains. Default map setup will be California conditions 1K ft elevations. User will have to alter if do not live in California, and also at extreme temp differences. If do not alter only get ¼-1/2 hp improvement. This is intended for racers trying to squeeze out every little bit out of the engine by optimizing. To the other comment that only heard great reviews, I have all the magazines and when you stack it up the following comes out: -[B]Rear end super tall [/B] which throws off balance feel, must run a lot of sag to balance out and if run a lot of sag that erases the goal of the frame changes honda intended. Fix: linkage $225 or a spacer put into the shock(most suspension guys are doing the spacer thing- though I do not like that approach $125) -[B]turning/Overstearing [/B] is hampered by high rear end that puts a lot of weight bias on front forks (diving) so suggest stiffer springs in front ~$123 -[B]Engine top end is flat[/B] - no over rev. All slip on pipes added overev to the bike. ~$450 All of the above are and were simple fixes - just cost some money ~$700+. That is the reason why not all magazines gave it #1 rating. When you have to put coin in to fix problems that is an issue. Recall? Well after investigating some more this is what I found out: Honda service has not recieved any bullitens yet. Those guys getting their bikes fixed are getting it done with the stock parts at present. Those guys all purchased their bikes from the same dealer who also has one of the largest engine hop-up shops in motocross. I do not want to mention their name because I do not want to bad mouth them, they generally do great work, just very expensive. I am assuming that the dealership is fixing the bikes free since their hop-up shop modified their engines. I will assume that possibly when the engines were modified, that the pin was not put in correctly. The engines are new and everyone is still learning how to service them. This hop up shop does have/sponsor a race team for the past couple of years. Spokes574 Pleasanton, California [/QUOTE]
