Yes and have not seen one yet make those numbers. Best I've seen 135hp

 

[DragoBikeWorks]

Yes

That 135 is with the 120R AND the RX kit? That's an awful lot of coin for an engine with no warranty! Ijs!

Here's one we did rebuild 120 with Mva re worked heads
Andrews 64
New Dragula 2
Custom Pistons
This one need alittle more compression . In my OP
But customer was happy

Some more head work and a better cam than that 259e would get you what you are looking for. If that's whats in your stage IV kit. But if you are getting 110 now that's not bad for Stage 4. I just tuned one for local dealer with stock head pipe no catt Stage 4 and Cobra mufflers it made 103 hp and 106 tq.

Nice! Looks like fun! I don't need that much HP. I get about 110 out of my HD 103 w/SE Stage IV Kit. I could stand 10-15 more.

The one we just tuned Was Stage 4
58mm
Stock injectors
103 SE kit
Stage 4 heads 1.87 in Stock Exhaust V.
Stock head pipe No cat
Cobra mufflers 1.75 baffles
SE tuner

Ill be honest I have never seen great number with this kit.
We Tuned one with Woods 555 and Thunder header
105 HP 112 Tq It had
Stock Throttle
Stock Injectors
103 SE kit
And Stage 4 head
Thunder header
We bent the baffle on Thunder header to help get rid of dip. Lost a little top end with that.

They claim that 103hp is about normal for a stage IV. I have whatever cams come with the street stage IV Kit, not the race Kit. It doesn't come with injectors either. I have V&H power duals with 4" Rineharts.
