Hey I am going to be rebuilding my engine for the 2012 AMA Supersport class and I am wondering about what kind of pistons and internals I can get. I know I can not do much but do I have to get OEM pistons made by honda? Or what? I am going to start slowly buying engine parts to rebuild it and I just do not know that much about it. Thanks!!

How do they work the five year cycle? 2008, 09, 10, 11 and 12?

Send it to EDR Performance :thumbup Done deal.
 
The rules are pretty open to what you can do.:) Be very careful about doing ANY port work, the cylinder head on the new bikes today work so well, that I have seen time, and time again some one is going to make it, "better" and they'll get in there with a porting tool and loose 5 to 6 hp right off the bat. This does not mean bowl blending,matching inlet boots to the port. HRC cams in most case are always good but be sure you don't over cam the motor. it's easy to do.
Compression and combustion chamber efficiency is where it at. But not to much compression. The devil is in the details. and getting the "right" cam numbers. Balance the bottom end and that means Piston crank rods rotor. That makes the bike a lot nicer to ride. Knife edging. is good of a couple of ponys but lighting these new cranks is not where you want to go. The dam things are already pretty dam light and you can make it impossible to balance.
If you get the bottom end put together, and need help with setting up the top end. Give me a call. We can help you put the right number in with out all the smoke and mirrors.:ride:thumbup. Then dial in the tune on are Dyno. You have a sinkness for quickness. We have the cure:thumbup
 
I have the same bike as you and would love to do the power up kit from HRC along with a few other goodies from HRC....but im still working on that lotto win, lol.

+1. Learning about building an engine while trying to do well at nationals is a big task. Eric Dorn and his guys put together a great engine in my R6.

Took me a while... but I think I finally found a sore spot:laughing With the number of slings and arrows in here, you're the man of steel to have survived this long... so it must be a REALLY juicy story:teeth

BRB, gonna bleed my lines before karma rapes me.
 
Bleeding your lines won't help...the man of Steel is Superman. I prefer a different super hero..

I've got some juicy stories, but they don't involve crashing...and yeah, they're complete disasters of stories! Course that's what memory loss is good for!
 
building a competitive 600 is NOT something you just do! Hell i have done over 100 R6's since 2006 alone and im STILL trying new things, changing small things, adjusting this or that. its constant. a honda is NOT the best platform imo they make the least power, especially top end/overrev of them all. the gear ratios are AWFUL for US tighter tracks, no slipper, etc. Still bulletproof engines. As for cylinder heads, i disagree with KC, some new bikes heads are garbage! the 09+R1 is one of the worst ever in recent years. The R6 is good maybe the best of the 600's but still you can get GOOD improvements with headwork BUT its not SS or DSB legal.

Keep it as simple and reliable as possible. power will not be the hardest thing racing ama. I know we are almost always in the top 5 for trap speeds but to get top 5 in the race takes the racer, suspension, brakes, etc...not just power. good luck

OK Eric you disagree with me. Cool If you don't mind could you elaborate. as to why. The only thing I ask, is if we could keep it real, not anecdotal. If you have a flow chart of and 09 head. If you don't want to share that and I relay could not blame you. It takes time and effort... maybe some flow numbers. and or percentages as compared to other heads. :)

No worries KC its ok for us to agree to disagree. Yes I do have flow charts but no I don't share sorry. Again what's point? Posting charts graphs or facts on here pointless at times, It'd be like winning the Special Olympics ...I still only beat a bunch retards.

Again its all good on my end man but yes some heads are junk not 1988-89 gsxr750 bad but relative to others they are. Some like 08+ zx10 or cbr1000rr can gain some good mid but much up top but a 09 R1 you can really improve on. Same with cams. Some like K9 gsxr1000 not worth changing but 08+ cbr1000rr and watch out big gains! Some other mods really help like kit hrc 1st gear on OP bike makes bug change while R6 box ratios pretty good stock.

Eric Come on your going to take a big hit in the credibly department here. You make a statement about a product being bad, but you offer no evidence to support your position. you have a golden opportunity here to show all a "Cali boys". How good you say you are, with your flow bench you do have a flow beach right? and your porting ability. How you can out think the multimillion dollar engineering departments of the motorcycle manufacturers and improve on their Port designs on any of the new bikes. now I need to qualify that, starting with the year 08 and above. Now i'm trying to give you the benefit of the doubt here. And i don't want this to degrade into a silly word thing like you and i have had in the past. But any time some tells me something like what you have stated here. and they won't offer and kind of data. and you are expecting us "retards" to just accepted what you are saying. Relay now Eric who is the retard :)

KC i wasn't calling YOU the retard..its a saying about forums in general, sorry if you took it that way. wasnt intention. I dont need to post up flow charts and dyno's all the time..i think the numbers of racers choosing to use us/EDR are proof enough, sorry man. i go by word of mouth more than anything.

What product am i saying is bad? I dont recall a product being discussed. maybe i missed it...too many long hours and concussions :)
 
I can personally say that EDR is the best. I have had work done by so many other builders/tuners that all talk a big game but never have the skill or work ethic to back it up. I've had EDR taking care of my bikes now for a couple years and I'll never take them to anyone else.

Hell, one of my buddies for the longest time was having trouble with his bike. He took it to a bunch of different places in Cali and none of them could fix the problem. They all told him he either had a bad motor or a bad PC. He spent an ass load of $$$ and after that, he still had the same problems. I told him to take it to EDR and Eric and his guys had it fixed within a couple days. Since then, no problems. He to is now and EDR only guy.
