Build or buy expansion chamber?

The tall handlebars and lack of front brake are bad ideas for a bike focused on speed.
I was able to attain 66kph with 44t so I don't understand the need for a 28t.
My experienced guess is that it will be a slug. Which is probably a good idea with no front brake.

Edited - not proud of my original remark. Tired and grumpy. Sorry about that.

I could never understand the apehangers, I can't see how they could be comfortable on Long ride
 
I've had apehangers before and its not bad. I always go on long rides. Used to drive 14 miles both ways to work every day. I got these tall ones more as a head turner than anything. Lol
 
I know i will see good gains with the port work i have done. Like i said, i got lucky with the porting. I looked at the ported jug on one of the sites and tried to mimik it. It was fun and the extra pull in the mid range was a plus. I also shaved a semi-circle into the bottom of the piston to match the port at tdc
 
I think got an increase of about 5mph ish

It has noticeable top end boost but the bottom end is a little less.... (I am used to no baffled stock exhaust)

It is kinda heavy too so it needs some mounts made for the back. I just ran the exhaust studs and they wouldn't hold it without major vibration

I recommend for a cheaper substitute of the SBP expansion chamber
