Would you go with boring your factory cylinders out to a 107 or just opt for a drop on 110 kit?

Considering that I'm semi retired and on limited income, I would go with my cylinders being bored. I love your awesome and informative videos.

Looking at a 103 Streetglide. I have a set of Woods 222 to go in it upon purchase. If the bike has a few miles on it I may consider doing this as a part of a freshen up when the cams go in. What compression will still work with these cams? Will probably leave the heads stock as I'm not chasing that last 5-10hp.

As far as H-D goes, more can definately be done with less. The XR 750 was one of the baddest engines H-D ever made. It was basically a destroked Sportster. Keeping the same bore but shortening the stroke from 3.811 inches to 3.00 inches allowed for a higher Rev limit and boost hp output to 85-100 hp. I have always thought that one of H-D's biggest mistakes was not making a street version of this bike. The second was when they quit making it.

[@chrisl.7345]

I agree with you a long way Gixxer, but I have never been a fan of high compression pistons on a Harley. High compression will put an extra pressure on your crank bearings, rod bushings and stress your starter to break. I prefer a max cam lift with stock springs and ported heads instead, even with a “non-easy start” set up the oem starter has no problems activating the stock springs. Ouh I love horsepower but I also love a reliable and steady bike which doesn’t sound like it’s going through torture every time it starts. Many of my friends has paid fortunes for starters and starter gears. Crazy HP bikes comes at a cost….it’s like riding the famous Tiger: It looks good but it will get you in the end !

[@GixxerFoo]

Higher compression is pretty harsh, compression releases are an absolute must to get started. It's a better idea to go with a build crank for high compression increases, but a cam with head porting usually gets the job done pretty well.

Get head work and compression relief. And Primos 84 tooth ring gear with the screaming eagle clutch spring and plates or a high end clutch. Get screaming eagle ignition for high compression. Topped off with a 2 into 1 ! That set up is extremely responsive quick and hard hitting. It make the bike extremely quick and pulls hard that’s my set up for my 02 Nightrain.

Cams can really add some power to a 103, they have the extra displacement over the 96 which helps quite a bit.
