The install went pretty smooth.  I had to massage the frame a bit for clearance.  I don't like the choke proximity to the fuel petcock.  But it works, its just real tight.  My Yamaha fuel petcock conversion hit on the carb, so I was unable to use that.

As far as performance, it runs like a raped ape.  Its a shame it didn't come like this from the factory.

Bottom line is that the carb is great.  I can't speak to the incremental improvement because when I installed this it was the same time as a BBK, cams, and MRD, with a crankcase swap.  So this was necessary to feed the thirsty cylinder.  But damn does it make power everywhere.  Takes some tweaking though.  Take my advise.  BUY THE FUEL SCREW WITH IT!!

Throttle response was improved and it makes more power. The downside is the carb is more sensitive to climatic and altitude changes.

Saved my bike. I just couldn't keep the OEM from leaking . The instructions could b e clearer. Searching the internet is required to answer all the questions
