Break-in after engine mods
Got to wondering about this the other day. My DXi has recently had the 95 kit and new cams installed and was considering the best way to break-in the new bores. Should I...
1. Start over, like it's a new motor or...
2. Just run her gently for a hundred miles or so, bearing in mind the rest of the motor (crank, heads, tranny etc) is nicely loosened up after 2000 miles.
Thanks for any input.

Its just that I hate the way it looks I thought it would flow a little more than it dose but it stands out like a sore thumb I feel. I am enjoying it now but it isn't all its cracked up to be. Man it's FU%& freezing here now. I wish I was somewhere I could ride in comfort 12 months out of the year.

I hear ya intruder I just got a quick release for my DWG 2 days ago and don't really like it either. Maybe it takes some getting used to.

RE: Break-in after engine mods
The quickest, and in my opinion, best way to break in the rings is to find a nice long hill. Start down the hill at 40-50 MPH and gear down to 3rd, and with no throttle, let the "compression" of the motor pull it down. Halfway down the hill downshift to 2nd gear and continue on. Do this 2-3 times, and the rings are broken in! When on the highway alternate you speed 5 mph every once in a while, which is of course changing the RPM's. ( with the hill trick this isn't necessary, 2-3 hill rides, and then just ride as normal
)
But as I said, do the hill trick and in 40 miles the motor is broken in, maybe even sooner since you're only breaking in the rings!

I would be safe and break it in as a new engine, despite some components already broken in. Vary the throttle, don't drone down a long highway, don't lug the engine, don't hammer the engine at high RPMs. The miles and break-in will be over before you know it. Can still have fun with your new 95" engine.
As for the quick release windshield, after six months of having it on the WG I took it off. Mounting hardware too. Could not stand the looks. Plus the wind abatement was minimal. Still a breezy, buffeting ride. Can understand keeping it on for the winter, but I was fine last winter without. Just cover the face, ears, and enjoy the appearance of your ride.

PS..Yes, that detachable windshield, for the most part, sucks. I use mine only to keep from freezing my *** off in the cold weather.

RE: Break-in after engine mods
Thanks for the input guys
Yesterday I got to look at the 88cu" pistons which were removed from my motor, and they looked really clean. No blow-by evident (they were 2200 miles old) and looking in excellent shape. It looks like how the bike was broken-in from new to be about right - as a result I've done 100 or so miles on the new bores in the same fashion ie letting the motor spin fairly hard (ie up to approx 4000rpm) in the lower 3 gears, but under a light load, with plenty of loooooong decceleration in higher gears to seat the rings.
Already, the extra urgency from a standing start is very noticable - the shifts through the gears happen a LOT quicker now! Bike even sounds different - lower-pitched, less hard-edged but definitely 'meatier'. Fuelling is now spot-on aswell with virtually no banging and popping on the overrun.
To say I'm a happy bunny would be an understatement.
Oh...did I forget to say I love this bike???
