I used to use the S&S carbs in my racing days but became fond of the Mikuni after working with the people
there to create a California Air Resource Board compatible motor many years back.
When I would ship motorcycles worldwide, it was difficult to tune for everyone, which is probably why
Harley-Davidson® went with the CV carburetor. I found the Mikuni carb is much more forgiving than most
I’ve tried when it comes to altitude and jetting situations.
I’m at 5,000 feet and close to Lake Tahoe, which is 8,000 feet in some areas. This can cause problems
with a bike running too rich, which can foul plugs and leave you stranded along side the road. It can also
blue your expensive exhaust system.
I’m not sure how to even say this, but to throw the carburetor at the bike would have required more work
than the installation of it. That’s why there aren’t more photos. Simply follow the directions included and
it falls into place without effort.
Right out of the box it looks really good with the polished carb and polished billet cover. When I fired the
motor up for the first time it did not even make a complete revolution before it came to life. The carburetor
was adjusted that close right out of the box. You just can’t go wrong with one of these kits from Rivera,
regardless of which motor you use.
Now it’s time to finish installing the BDL open belt drive primary system. Since you should have already
done this during pre-assembly it should be even easier. This time use red Loctite as directed in the
instructions on the front pulley and clutch hub.

Put red Loctite on
the oil filter screw
and insert it into
the hole.

Again, use Loctite and
insert the stainless
plate and bolts into
the back of the front
pulley.

There are three pins that get tapped into the pulley crank adapter to keep things
lined up. Get them started in the holes prior putting the front pulley on. It will just be
easier with the pulley sitting on the table and looking down into the holes.
Slide the back clutch basket pulley onto the transmission shaft and then insert the
front pulley into the belt and slide it onto the hub spacer being sure to line up the
holes as you do so.
Tighten up the three Allen bolts that hold these pieces together and then, using a drift punch, tap the
alignment pins in flush.
