XRL Diet Plan and Jetting
At over 47 lbs heavier than the already heavy XR 600 the weight of the
650 really makes itself known when the street turns to dirt. Other than
removing its gas cap and rolling a Husaberg underneath, following are
a few ways to remove excess flab from your XRL. By replacing the stock
headlight with a Baja Designs headlight, the mirrors with Acerbis plastic
mirrors, and replacing the stock bend-0-matic handlebars with Renthals
you can remove 3 lbs of highly placed weight. Baja Designs Headlight:
$88.00 Acerbis Mirrors: $15.00 Renthal Handlebars: $70.00
The unsightly smog pump and carbon canisters can be removed for off-road
use to save 2 lbs 4 oz. with a block off kit for $19.95.
The TV set that Honda calls a taillight can be replaced with a 2 lb. lighter
and much lower profile unit from Acerbis. Mounts to the stock fender and
is fully street legal. See color photos for taillight on XR, DR, and kit
parts. DOT Taillight: $38.00 wired and assembled; and $32.00 unassembled.
Removing the steel tank and wings and replacing them with the IMS 4.0
gallon tank or Acerbis 5 gallon tank saves 7 lbs and gives the bike a
much greater fuel range. IMS Tank: $190.00 - Acerbis Tank: $185.00
Remove the buddy pegs, and combined with the above modifications, you
have removed 16-1/2 pounds of excess pork from your 650L. Remove XRL 650
and replace with XR 600 and Baja Designs Conversion Kit: About $4400.
Weight Savings 41 lb. (Sorry - couldn't resist!)
Jetting the XRL 650
The CV (constant velocity) carburetor on the 650L is very sensitive to
changes in intake and exhaust restrictions. Many people, desiring more
power from the mildly tuned 650L motor will remove the airbox snorkel
and install a decent air filter and a lower restriction exhaust. The bike
will pick up 3 to 6 horsepower with these mods, but will run terrible,
bogging horribly anytime you whack the throttle hard. Simply rejetting
the carb will not fix the problem. After many hours of testing and experimentation,
we found that the problem was in the vacuum piston of the CV carb. Baja
Designs now offers a simple to install kit that includes the proper jetting
and necessary modifications to the vacuum piston and pilot circuit to
allow the bike to run properly. XRL 650 Jetting Kit: $21.95 Smog Block-Off
Kit for XRL 650 Price: $19.95
