So far I mainly focused on performance mods. PCV, Chimera intake(Sprint Filter), Brock's exhaust and DCR cam. Looking to see if there are others following same/similar path.

I have the exact same stuff with out the cam. 10.66 hp on Brock's dyno. Bike runs much better than stock and pulls hills better. Odd mine seems to run a little better with the d.b. killer in than it does with the pipe wide open.

needs that backpressure on the stock motor. Big exhausts on stock motors actually reduce power. I don't run it just so the bike is loud and the idiots on the road can hear me. A little power isnt worth my life. But I got a 178cc TB kit with V2 head going in it soon. Just waiting for my slipper clutch to get here and then the build will start.

Do you mind providing link to the DB killer?

Where did you find a slipper clutch?

The Takegawa 6 disc clutch kit for Kawasaki 110/125 engines now has a slipper function. I've run the standard style 6 disc clutch on my bigger builds since the extra capacity prevents clutch slip and the primary gears are taller for a higher top speed. But now I want one for a 125cc class racebike and the 14% higher gearing is a bummer since I've already geared it down for the tight kart tracks we run. Currently there is only a part# that includes a new clutch cover so this complete kit will be $pendy. Hopefully someday the slipper clutch portion will be available on it's own like the one they sell for the GROM. But if you are building a monster big bore engine then this is a nice clutch upgrade kit for it.
