Description
Fitment: 2017-Newer Harley M8 Motorcycles (Touring and Softail Models)
CSR Throttle Body
Cycle Solutions Inc. is known for their top performing throttle bodies. You can squeeze more power from your M8 engine by switching out that plastic stock throttle body and replacing it with a CSR 58mm or 62mm throttle body. We are getting huge horsepower gains with the new M8 engines with a stage 1 and 2 cam upgrade so it is no surprise that there are even more gains to be achieved by getting that plastic stock throttle body out of there and installing one of our 58mm or 62mm CSR throttle bodies.
The stock M8 throttle body is a 55mm and it has a plastic plenum that can change shape under load and also has been known to melt due to high cylinder head temps. Nothing is more disappointing then to take off an air intake to discover that the throttle body has failed.
Our high performance motorcycle throttle bodies are made from high quality 356 aluminum castings to ensure perfect OEM fit every time. They will not warp or melt! We utilize your stock core electronics and build them into a new throttle body casting, CNC ported manifold, complete with new intake flanges and seals. Our throttle bodies are compatible with stock map sensors, fuel rail and cruise control and are all designed to increase airflow and improve performance. We stock many styles of 58mm and larger motorcycle air intakes that bolt right up and will complement any motorcycle.
Our dyno shows huge gains on the M8 engines when using our quality products. This dyno graph is for our 2017 Road King. We installed the D&D Billet Cat exhaust system, a Thundermax auto tune module, CSR air intake, 58mm CSR throttle body and a T-man 216 Cam chest upgrade. This bike gained 38 horsepower which is incredible!
Add High Flow Injectors to your Throttle body
Horsepower Inc High Flow Injectors are a direct drop-in replacement for Harley Davidson Motorcycles. These injectors feature a specifically engineered spray pattern that optimizes fuel atomization. These injectors have a fuel deliver rate of 6.2gps and are highly recommended for engines making or exceeding 110 horsepower.
Need to upgrade your air intake to match your new larger throttle body?
Cycle Solutions Inc offers several styles of motorcycle air intakes that have a backing plate specifically for a 58mm and larger throttle body. Our intakes have larger openings that match up perfectly to our large throttle bodies so that there is no air flow restrictions letting your throttle body breathe! Be sure to check out our air intake section when purchasing a larger throttle body.
