How difficult is installation for a home mechanic?

Installation is straightforward for anyone familiar with simple carb swaps. Basic tools and minor adjustments—throttle cable alignment and fuel line routing—are typically all that’s required.

• Swap uses existing throttle and fuel fittings in most cases
• Allow time to fine-tune idle mixture and jetting after fitment
• Follow safety procedures when working with fuel

What should I check before ordering?

Measure your bike’s intake manifold dimensions and compare fastener spacing to the carb specifications to ensure compatibility. Confirm whether your bike uses similar VR/VM-style carbs; if unsure, compare photos or consult a mechanic.

• Verify outlet and inner throat diameters (26mm / 22mm)
• Confirm manifold bolt center-to-center = 48mm
• Check bolt hole diameter = 6.5mm for mounting bolts
• Compare throttle cable and fuel line ends to your current carb
