Product Overview
This cam is for an owner deliberately moving power higher in the rev range—not for fixing low compression, poor jetting, tight valves, a stretched chain, or a worn head. The engine must be healthy and the fuel, exhaust, valve-train, and riding setup should support the more aggressive profile.
The 1043-2 cam changes valve lift and duration to favor stronger mid-to-top performance. Piston-to-valve clearance, spring condition, rocker or follower surfaces, decompression arrangement, chain and tensioner condition, timing marks, and valve lash must be verified on the actual build.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Will a Stage 2 cam fix an engine with low compression? A: No. Ring, cylinder, valve, and head problems must be repaired before performance tuning.
Q: Does this cam require fuel or exhaust tuning? A: The best setup depends on the engine and supporting parts; jetting or EFI and exhaust changes may be needed to use the new airflow safely.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
