Tuningkits

We offer complete tuning kits or individual tuning services according to your needs. First of all, it must be clearly stated that changes of any kind on the components is not street legal !! Your racing engine is only for racing use!

Each engine is unique! Therefore, performance deviations of up to 20% from the test bench diagrams shown here are possible. This depends on many components (jetting, exhaust, tire pressure, test bench software, etc.) and is no reason for complaints!

Basically, a distinction must be made between 3- and 4-stud bolts. For the 3-stud bolts (fender light), we have the engines with 1 and 2 transfer ports.  

Let's start with the fender light engines with 1 transfer port. The wideframe engines with 4 stud bolts can be found under the category GS 150.
