Sure..Sun ever stays out we can meet for a burger or something, I've met Torch and Reindeer from the forum and they're good guys to meet and greet.

Not far from you, I'm just east of lake Nokomis

I should have some free time Saturday afternoon. I'll shoot you a text or something, maybe ride down your way if its not raining too bad. Your bike looks good, I like that exhaust system.

 

Thanks.
I want to see your bike too, looks good in the picture.

All goes well, maybe see if anybody else wants to join or meet for a burger/whatever?

Finally made it down to Fairbault HD, and met Jason.

Guy definitely sounds like he has been doing this a while.
We spent some time discussing getting the WG on the dyno, and what I had done to it, seems all was well until I mentioned the PC5 and Autotune.

While each builder or mechanic has their own idea's on what does what the best, the negatives he mentioned to me about the Autotune seemed to ring true, or at least have some validity.

One, the AT seems to hunt a lot, a roll on in 4 gear at 2500 rpm is nice but not as nice if I repeat it a second time.

Engine seems to run either rough or smooth depending on..I'm assuming..the tune that the AT has dialed in.

Fuel economy sucks, especially when the temp is above 80 and the motor get hot.

I have over 400 miles on the bike since finding the dummy plug needs to be in, it should be dialed in.

Jason suggested to run the TT mastertune, ok, it was my first choice, but the AT feature of the PC5 just seemed to be the way to go for this old guy.

So..what do I do?

I had a fishing trip cancel out so I have a few extra bucks to play with, and I can't get into dyno the bike until a week from friday so, I'm going try and get as many miles on as I can to give the AT extra time to work.

I'll try and get mileage reading and a seat of the pants performance for overall riding.

Then I'll have Jason dyno the bike and we'll remove the PC5 and AT and he'll install the TT unit and set that up and dyno that, I'll be able to compare the two dyno runs, plus ride for a bit with the TT set up and see which I like the most.

This is way more money than I had planed on, but in all reality it is my last bike and for me it will settle the question of which of the two tuners is best for me.

Jason also mentioned he can set the TT up to run a hair lean for gas economy and richen up a bit for major throttle settings, and something that caught my attention was he says going by past experience he can get about 10 more HP out of the motor..hummmmm we'll see.

I will post the results and those what want can use it as a unscientific comparison of the two.
Considering the comparison on the dyno will be done on the same bike and within a 4 hour period, I'd think conditions should be not a factor.

Ought to be interesting as I don't remember seeing a post on someone doing this.

Just wanted to thank all those who have helped or made suggestions.

I have not came back to this thread since my first post, been missing out - great thread. Thanks for posting some pics. I am planning a simular build in the future, just trying to learn as much as possible before buying anything. Have a few random questions if you don't mind?

With the headwork, did you have to do anything to your pistons? Can't remember if you got larger valves or not.

Do you have an oil cooler or a fan? Doesn't that build create extra heat?

Did you keep the stock lifters?

Which pushrods did you use - happy with them?

When you took off your tank, how did you handle that crossover hose?

Sorry, if I ask too many question - I can be painful that way!

 

No problem, many helped me get through my rebuild, glad to help.

Also check here for final numbers and ignition change out

With those high lift cams and larger valves, did Revolution guarantee the clearance between the valves and the piston tops or did you use modeling clay to verify proper clearance. The reason I am asking is because when I brought up a simular build idea in another thread, Scott from Hillside said that my piston valve reliefs might have to get checked to ensure clearance. It seems to me that the head porting guys should know if a modified/ported head will work with stock pistons or not.

 

I think the cams used will make all the difference, as the valve timing changes.

 

Hey Reindeer, I had not thought about the timing influence. In the other thread I did not mention any specific set of cams, so maybe that's why Scott said what he did. I am just wanting to know if these guys that do head porting are able to ensure that the heads that they send back are good to go with stock pistons. I know I could call them personally, but I am still a long way from ordering and not wanting to bother them until I am closer to ordering.

 

When I talked to Revolution they said this was all bolt on, no mods required.
I did not use clay to check clearance, (probably should have) but they at Revolution were sure this combination worked and it does.

They had a track record with these cams and heads with the 103 motor already.
