OK, gang, let's hear your opinions. I want it ported and they may as well put a ring in it and run a hone through it while they have it. I'd also like them to split the cases and make sure everything is good and replace any worn parts, etc.
If you'll remember my last post here, you will see I've complained of late about the bike jumping into neutral on rare occasions. I rode WW Ranch this past Saturday and it only did it once, and I'm almost sure it was my giant foot.
I've seen some opinions here about Eric Gorr that seem very positive. I sent them an e-mail over a week ago and have yet to hear back from them. It was a pretty simple e-mail that told them what I was looking for and could they give me a ballpark figure. Not responding sort of turns me off, but I do know that folks get busy during the Christmas season. Still though, over a week is plenty of time to at least say, "We're very busy, but want your business. Please allow us X days to get back with you."
OK, let's hear what you all got to say. Sell me on somebody.

815-261-6907 if Brent doesn't answer he's probably got one on the dyno or machining something. He will call you back asap though.

I'd like to see more mid-range punch. Having said that, let me just tell you that it really does not need anything. I just want to do it because I can. I'm out to build the perfect beast. I'm currently running the engine stock with the following bolt-ons.
FMF Fatty.
Pro-circuit shorty.
Steahly fly-wheel weight.
V-Force 3 reeds.
Thanks.
I've got about 40 hours on it now, and it still requires a full boot to kick it over. It runs great, and everyone that rides it says it is one awesome machine in both power and suspension. Yet, I carry on to build the perfect beast.
When I saw all the crazy-lean jetting that guys on thumpertalk were running I experimented with it just to try. Stock is 50/178 on the pilot and main. These guys are running down in the 42/162-165 range ! I don't know how. I am at elevation and even here their jetting seems ridiculously lean. I tried going to a 48 on the pilot and got the bogs. I tried 172 and 175 mains and it just felt weak and lazy.
The only thing I ended up changing was the needle. Went from the stock N3EJ to the 1/2 clip leaner N3CJ. It really cleaned it up nice and the bike rips. When the temps drop below 60 I put a 180 main in and it still flies.
If I was going to do any porting, I would probably do it on a spare cylinder. The stock engine is really good and most consider it great all around . I've ridden many bikes over the years that were ported by so-called experts and many actually seemed worse than stock. i.e gave up too much bottom to get some top or just had a huge mid-range hit and nothing else. Ultimately less effective on the track.
I talked with Brent for a bit, one smart guy......a bonus of you sending a complete engine to him, he can run it on his dyno, so there is no guessing on what you wanted and what he did....
at some point I will probably send him my 325 cylinder and head to see if he can improve on it....
I 100 percent recommend him.....
FGR, I appreciate your informative post. I should probably follow your advice and skip the porting. I could spend that money on getting the crank perfectly balanced and the gears polished.
Jake's Dad, hope the doggy gets better!
And how many tuners write books? Eric has written several. Smart, Talented Dude.

I find it interesting that no one (so far) has said something like, "You just gotta send your engine to Pro-Circuit!"
Pit Row
can't believe that Pro Circuit has done much 2 stroke RD since 2004 for reeds bike, maybe AC's super mini.....I think all the tuners mentioned in this thread are more current and can give you what your looking for....
I would still recommend a 295cc big bore, setup for smoother power. When you are racing against 450's, you need more torque, rather than peaky top end horse power.
