Valve Clearance Adjustment Kit (Valve Shim Kit) for Royal Enfield Himalayan 450 (Sherpa 452) – KLA00079 / KLA00079/A (Genuine OEM)

Royal Enfield KLA00079 (also sold as KLA00079/A) is the genuine Valve Clearance / Valve Shim Adjustment Kit used when setting correct valve clearances on the Himalayan 450 (Sherpa 452 platform). Dealer catalogs describe it explicitly as a “Valve Clearance – Adjustment Kit,” and it’s commonly referenced as the required kit for Himalayan 450 valve-clearance work.

When valve clearances drift out of spec, riders often notice tappet/valvetrain noise, rough idle, reduced performance, or inconsistent cold starts. This kit supports accurate adjustment during scheduled maintenance—especially important on a new-generation engine where correct clearances protect long-term reliability.

FAQs 

Q1 (Fitment): How do I confirm this is the correct kit for my bike?
Confirm you own a Royal Enfield Himalayan 450 (Sherpa 452) and match the part number KLA00079 / KLA00079/A in your service estimate. Best practice: share a photo of your estimate or kit label before ordering.

Q2 (Fitment): Will this work on Guerrilla 450 since it’s also a 450 platform?
Do not assume. While some marketplace listings claim it, we only mark ✅ when trusted catalogs confirm. For Guerrilla 450, please verify by VIN/service estimate first.

Q3 (Comparison): OEM kit vs aftermarket shim sets—what’s safer?
OEM-numbered kits are typically closer to factory spec and reduce sizing/material uncertainty. Aftermarket assortments may fit “on paper” but can vary in tolerance and labeling—leading to repeat work or noise if sizes aren’t accurate.

Q4 (Installation): What tools/precautions are needed for Himalayan 450 valve clearance work?
Valve-clearance work requires correct TDC locking/positioning and careful measurement. Many guides reference using the Valve Clearance Adjustment Kit (KLA00079) along with dedicated TDC locking tools and standard measuring equipment. Use a trained mechanic if you’re not experienced.

Q5 (Symptoms): What problems does this kit help solve?
Common symptoms include valvetrain/tappet noise, rough idle, poor throttle response, and inconsistent cold starting—often linked to clearances drifting out of spec.

Q6 (Returns-prevention): What should I check before buying to avoid a wrong order?

1. Confirm Himalayan 450 (not 411/Scram). 2) Confirm PN KLA00079 / KLA00079/A from service estimate. 3) If uncertain, send VIN + estimate photo for confirmation before dispatch.
