First Off let me start off by saying I'm extremely new at riding, when I say new I mean I laid my bike down going 5 mph cause I hit some gravel as I was attempting to turn around. My question is I bought this bike last year but cannot find any info on the heads, all I can see is a label on them that says Hemi HQ, it is a carburated 110 03 night train with a bdl open belt drive and baker 6. Any help is appreciated, thank you.

 

Pictures are worth a thousand words. Just a guess but at one time there were a few companies making heads for harleys and the claimed they were hemi, hemispherical, not sure about that claim but some of those were 4 valve heads too. Try googling 4 valve heads for the twin cam...thats what I was looking for but I don't remember everything about it.

 

I'm not sure about the 'hemi' part, but there is a firm called Head Quarters, who may be the 'HQ'?

 

Hemi HQ is an aftermarket company who sold heads/ piston /cam kits for big twins. Cant remember where they were based out of - but they were an advertiser in American Iron magazine. I remember the ad touted their top speed on one of their test bikes at what looked like the Salt Flats.

 

So it's a good engine then? I couldnt find any products on them that's why I was asking. I'll take some pictures once I get home and post them up ad well. Side note, is there a website to learn how to work on these aftermarket parts myself, I work on cars but bikes are a different animal.

 

You should definitely get a Factory Service Manual...... Very important...

 

there was a company doing hemi combustion chamber & pistons a while ago,never made much sence to me.basicly taking a evo or twin cam chamber & turning into a shovelhead

 

Sorry guys I got it wrong its hemi ho.

 

i knew ive seen it before- looks like some nice parts......
