^^ Stsge 1 on the M8s does nothing for performance improvement. They breathe as well as they need to as designed. But, yes…Stage 2 does need to breathe better…so stage 2 needs better AC & Mufflers.

 

Range was another reason I went with the Transformer . 4 gallon aux fuel with electric transfer pump. Range became a issue a few times with the large sidecar rig. I do expect the trike to do better. But just did not want to deal with the short range.

Another thing to consider is as you add more power. Are you going to really be able to use it. If the Trikes setup is not up to the task you need to be ready to spend some more to improve it.

 

This is a 2018 107 trike- stock ve SE447 with the SE tuner. It helps, but nothing earth shattering.

 

I did the same Stage II, but removed the Cat 2 years ago. I appreciate the improvement in pulling power.
My fuel mileage increased after the cam; I easily see how it could go down with the new and improved throttle response. But, about 6k miles later, I believe the decrease in mpg is in the left wrist.

 

I took the bike in this morning. They had started on it before I left. Other than the screaming eagle intake, SE tuner, Tab performance sticks with zombie baffles, 447 SE cam, the heavy duty cam bearing, I had them install a decatted Harley head pipe that they had in stock.
They didn't give me any flack over the decatted head pipe and said they would defiantly warranty the bike.

That decatted pipe will surly help my wife's right leg out and mine too.

Oh, I made a typo in my first post. I still have a year and 8 months warranty left.

 

Always get a good foundation in place before building a Stage II, III or IV. Video on this subject below.

Regarding MPG. With a properly done Stage II, you will get better MPG than you got OEM. Video on that subject below also.

 

First of all, thanks for responding and I enjoyed your videos. I'v wacthed a number of your videos in the past and have gained knowledge from them.

I believe I'm starting with a pretty good foundation when it comes to intake and exhaust with the Tab pipes and much larger air cleaner. The SE pro street tuner and 447 cam probably aren't my best options for a stage 2 setup but, I still have 20 months of factory warranty that I wish to retain, or at least most of it. I may drop the SE pro street tuner and do another cam change after the warranty has expired if I'm not happy with the results.

Th SE intake I'm using is one of the better air intakes "I believe".

 

I don`t think so...

 

On mine, that was 95% highway with Cruise Control set at 65mph

 

I have the 2017 FW with the 107 M8 engine. Charts and graphs with curves and performance claims are ok but sitting in the seat and cranking down the road is how I measure performance and the effect of any upgrades that I have done. So I installed the DK Transformer EBS into the K&N Mini Chrome Filter, The Outlaw 606 non restricted Air Intake and a set of Vance & Hines Double Cut exhaust slip ons Not only was there a significant improvement to overall performance but the effect was obvious.

The Trike runs super smooth, pulls effortlessly in any gear, is clearly a substantial improvement in power and performance. Stage 1, 2, 3, 4 ?? .... I have been riding HD for the past 30 years. I have also had several high performance bikes prior to my growing into HD. IMHO, if your goal is to go really fast you should take a closer look at Suzuki, Honda, Kawasaki, Yamaha, Ducati etc.

If your goal is to increase power and throttle response, cool down your engine temp and thoroughly enjoy the improvement that these few modifications will absolutely make ... then let it breath and enjoy the ride!!
