Since we are getting things back together after Hurricane Michael (63” of salt water in my shop office & the building half destroyed) I want to get back to my 2015 CVO Road Glide modifications. I want to increase the cubic inches & have been looking @ 113 & 117 options. Heads will be done by WFO Larry & should be 95cc from what I understand. I’ve looked @ the Harley 117 option but the compression is lower than what I want & I don’t want to cut the heads so either a 117 with the right pistons or similar with a 113. Tb is an SE 58mm with 5.3 injectors, FM 2-1-2 & Kuryakyn Crusher mellows or regulars I have both. Air cleaner is up in the air, Tilley wants $274.00 plus shipping for their + 1". Tuner will probably be a TTS.
Has anyone used the Suburban Speed bolt on 117 cylinder & piston kit to make a Harley 110 into a 117 using the Harley cylinders & Mahle pistons. I'm curious how this setup has worked for the people that have done it. Like everyone I'm also curious about the longevity of the cylinders with the steel not cast liners.
This is from their website.
New from Suburban Speed 117 high compression 6.6cc piston & cylinder kit. Turn your Screamin’ Eagle 110 into a 117 without boring the cases, We worked with Mahle Motorsports and came up with a reliable piston & cylinder combination using the new Screamin’ Eagle cylinders, Pistons have a 6.6cc dome to give you 10.7 to 1 compression ratio using a .040 head gasket and come with coated skirts, ring grooves and pin bores, Kit also comes with 4.125 Cometic head gaskets.
I talked to Rick in the speedshop & he told me all of the compression values were figured with the pistons .005 in the hole not zero deck. The compression is a little higher than I was going to do so I might look @ different cam choices, Originally I was looking for 10.5 to 1 to use with the TW777’s I have. With the higher compression I would probably use my TR590’s. The other cams of interest are the GMR 600 & the Wood TW999. This is a heavy bike & I’m looking for as much torque down low as I can get but still run out to 6000 when needed.
Thanks Bob
