Husqvarna Tuning Packages
Extensive development and testing of valve and valve seat geometry, coupled with further investments in machining capabilities has enabled us to provide "silver" and "gold" tuning packages at a reduced cost.
The "Pro" version provides the ultimate result, while the "silver" and "Gold" liberate the majority of performance increases and represent excellent value for money.
For the 570 and 610 kick-start models, HMR offers the tuning packages below. If you are not in a position to remove and refit your engine, see our ride in ride out options.
Silver Tuning Package TC, TE, SMR
Modifications
Top end strip & rebuild (engine service base gasket upwards)
Stage one cylinder head work (valve seat position optimised for HMR valves, multi angle valve seat job, seats blended to ports. inlet manifold blended to port. VALVE GUIDE NOT REMOVED)
Fit valve spring conversion & set up spring tension
Lighten & polish rocker arms (stress relief and more acurate cam tracking)
Set up compression ratio (compression ratio optimised for specific application)
Clock through cam timing (for maximum efficiency)
Modify clutch (to cope with increased power)
The above modifications cost P.O.A.
Parts
HMR one piece valves
HMR lash caps
HMR stage one valve spring conversion
HMR lightweight tappet screw nuts
HMR clutch spring pre loaders
The above parts cost P.O.A.
Additional parts may be required, depending on how much work the engine has done.
These high performance modifications may compromise reliability and longevity of engine.
Silver ProTuning Package TC,TE, SMR
Modifications
Top end strip & rebuild (engine service base gasket upwards)
Stage three cylinder head work (valve guides removed, ports totally reworked, gasflowed modified guides re fitted, valve seat position optimised for HMR valves multi angle valve seat job, re working of combustion chamber)
Set up compression ratio (compression ratio optimised for specific application)
Lighten & polish rocker arms (stress relief & more accurate cam tracking)
Fit HMR camshaft, degree in
(for maximum efficiency)
The above modifications cost P.O.A.
Parts
HMR one piece valves
HMR valve lash caps
HMR stage two valve spring conversion
HMR lightweight tappet screw nuts
HMR camshaft
The above parts cost P.O.A.
Additional parts may be required, depending on how much work the engine has done. In the case of a new or nearly new engine this should just be gaskets.
The HMR Billet Clutch Pressure Plate conversion should be considered (detailed opposite), due to the power this package produces.These high performance modifications may compromise reliability and longevity of engine
Gold Tuning Package TC, TE, SMR

To expand the engine tuning packages to a "ride in, ride out" service
Engine tuning packages are priced assuming that a clean engine, drained of oil is presented to us.
To convert our engine tuning packages to a ride in, ride out service, please consider the following additions:
Base dyno run, before work is commenced £45+VAT (optional)
Removal and refitting of engine from chassis £195+VAT
Running in £50+VAT (optional)
Power check and typical carburation set up £100+VAT (optional)
