What motor are these?

[Randy H]

The Raptor block may not have Raptor (or racing spec) innards. It could be a Raptor block with standard 130XXX series parts inside--we really don't know what the OP is being offered

Please enlighten me as to the special internal Raptor parts.

FYI The only diffent internal part on a Raptor 1 is nothing. It's lacking a governor that is all.

Raptor 2 and 3 do have a one piece dipper, and better rod quality.

Of course anyone claiming knowledge of these engines would at least compare Raptor IPL's with regular 130000 series IPL's before making statements regarding the internal components. I mean otherwise it's just opinions and BS.

Found this on B&S's website:


"Racing connecting rod with integral oil dipper and larger radius I-beam.
Soild fuel tank bracket and improved tank to bracket connection.
Oil impregnated bronze exhaust valve guide for long competition life.
Revamped carburetor machining for uniform high- flow.
Redesigned head gasket for torque retention and heat transfer.
Longer high-strength head bolts for better control of head torque.
Silicon-beaded crankcase cover gasket for oil control and torque retention.
Upper retainer controls valve for spring control.
"As Cast" block, head and crankcase cover reduces combustion deposit and debris collection on internal parts."

This applies to Raptor 3. Raptor 1 had a regular old two piece dipper.

Yup.

I know.

Only Raptor 3s had the different block design, right?
