I have everything for the M8 stage 3 kit. The cylinders and pistons with rings are brand new. They have never been outta the boxes. Have the screaming eagle lifters along with the 498 cam. I purchased the stage 4 kit and used the heads, injectors, throttle body and cam outta the kit so this is why the pistons and cylinders are brand new.I already had the stage 3 kit so didn’t need the pistons and cyclinders. If really interested i can open boxes and take pics. This kit sells for 1595 from harley. I will sell this kit shipped to you for 750.00. If wanting the heads with screaming eagle springs and they also have the 114 badges on them i will take 350 for them shipped. This will put you into a 114 stage 3 for less than half what harley wants and this is all harley parts.

Forgot to add this kit according to Harley fits all 2017 and 2018 107’s and the heads are off 2017 Limited

So if I have a 17 RGU with the stock 107 now and buy your kit can I reuse my heads, injectors and throttle body or will I need to upgrade them?

 

Yes you Can use your heads injectors and throttle body which make it a stage 3. The heads with throttle body and injectors is the stage 4.

 

Ghost, what was the outcome of your Stage 4 with Stage 3 cam? That is as far as your warranty and the performance?

 

Dealer ended up not doing it cuz afraid Harley was gonna void the warranty. So went with the 515 cam. Today got to finally take bike out for ride. First time since was done. Got up to 33 degrees out. Bike really runs good. Has plenty of pull. But strange thing is it’s extremely quiet now almost like stick mufflers. The smart tuner is definitely working and has no flat spots or dead areas in the throttle.

 

Glad things seem to be working out. I'm sure you'll enjoy it. Our weather is killing me too.

 

Yeah it’s supposed to get to 40 tomorrow so plan on going for few hours. Heated gloves and jacket help a lot.

 

Sounds like a good deal for someone, wish we could ride, 4' of snow and-30*F, looking for April.

 

This is the stage 3 kit for the M8. It is lacking the gasket set for the install
