CRB-H01-1.0  $129.95
(87-89 only)

Standard drop-in carb kit

Easy to install and tune - no slide drilling
Adds more low-end / midrange, if the proper main jet is selected, more top-end power.
This is one of the kits that we made our reputation on - in fact the first jet kit we ever made.
Won lots of races - used by nearly every top team in the USA except American Honda's
(I'm pretty sure....).

CRB-H01-3.0   $129.95
(87-89 only)

Easy to install and tune - no slide drilling
Adds more low-end / midrange, if the proper main jet is selected, more top-end power.
This kit gives more power everywhere, as compared to stock airbox or any Config 10 / Stage 1 kit.
This is also one of the few "Config 30" kits that still uses the airbox - not individual air filters, like other #30 kits. The airbox lid is modified for increased air intake.
This is one of the kits that we made our reputation on - in fact the first jet kit we ever made.
Won lots of races - used by nearly every top team in the USA except Honda's (I think....).

SHFT-HON-1  $39.95

Make shifting MUCH quicker and virtually eliminate missed shifts. Helps address missed shifts caused by poor shift detent "star" profile.
Note- This kit will NOT fix rounded gear engagement dogs! It will help damage NOT occur to good gears caused by missing shifts.
The same kit that most AMA teams used "back in the day".

Requires clutch assembly removal - including complete clutch basket's big nut. An air or electric impact wrench is "the way" to go.
A shop would bill 2-2.5 hours.

A great time to do this is when you are replacing clutch plates as you are "right there".
