Flow improves with 19 cfm changing from a std 42mm to a 42mm Raptor venturie.They are also available for 51mm IDAs



1. Remove the lid of your IDA, pull out the acc jets, aux venturies and main venturies.
2. Make sure that the guide pin on the Raptor venturies is centered in the grove in the carb house.
3. Lubricate the o-rings and gently slide the venturi down till it stops.
4. Reinstall the acc jets and put the lid back on.

 JPM Billet Cylinder


JPM billet cylinder is made from cast iron with a very solide structure. The material is commonly used for hydraulic cylinders with pressures that never is experienced in a combustion engine. The choise of material prevents the cylinder to expand too much and therefor the valve lash is still controlable when engine is hot.

A common problem when stepping up to 94mm bore is big crank case breathing. The crank case breathing is because of a not circular cylinder, too deep releases i for the head studs makes the cylinder like a square when torqued. Too big difference in material thickness causes the cylinder to deform when torqued. JPM billet cylinder has a very even thickness and therefor it is perfectly round when torqued to specification. The OD of cylinder at top is made bigger(102mm 4.015") than std(101.1mm 3.98").
