Variants & Setup
Per HPSP's size guide: TS125 uses 42mm, RXZ uses 44mm, LC135 and LC135 (New) use 50mm, NSR/TZM use 50mm, UMA carburetors (24-28mm bore) use 50mm, and UMA carburetors (30, 32 and 34mm bore) use 55mm. Match the funnel size to your specific carburetor, not just the bike model, since UMA aftermarket carbs vary in bore size.
Installation & Package
Clips or bolts onto the carburetor's air intake mouth in place of the stock rubber intake boot or open bell. Package includes one air funnel in the selected size and colour.
Summary
HPSP Racing carburetor air funnel in four sizes and colours, matched to specific carburetor models.
Important Notes
For carbureted setups only; not applicable to fuel-injected models. Removing the stock air filter/intake boot for an open funnel can affect tuning (jetting) and reduce dust filtration - a rejet and cleaning schedule adjustment may be needed.
