Hey there, can anyone recommend someone to port my 78 DT400? 
Id like to get more power out of it. Maybe something close to a IT400. 
Im in CA if that matters. 

Thanks

I've done maybe stupid things "which I'm real good at with years of mistakes" whte I've made a 5mm alloy base plate to lift the cylinder then taken 5mm off the top of the cylinder in my primitive old lathe. Then spun the head & machined the step off to reclaim compression or hopefully raise it more than original to make up for raised ports. Realy need a better exhaust than standard. Na, just go get an IT400 motor. I got one from the wreckers about 30 years sgo which I fitted in my monoshock DT250 frame. THAT lit it up haha. Had a yz exhaust on too. Memories.
