Cheapo tuning tweak
All mass produced vehicles have stuff that works against the efficient running of the motor.
On a Harley the most obvious of these is the inlet manifold. If you hold the throttle open and push up the slide you can shine a light down the carby throat and see if any of the manifold is obstructing the airflow.....if you can see aluminium shining back at you around the join between carby and manifold then it is causing a hinderance to good flow.
Take the carby off and stuff the manifold with rags. Get a big blob of grease and smear it all over the rags where they sit in the manifold near to the material you need to remove.
Get a good, sharp half round file and take out the excess material. Keep checking at intervals by fitting the carby loosely back on and shining the light down the hole.
When its done, wipe the area where the filings are stuck to the grease, then pull the rags out and wipe the whole area clean.
Refit carby and go for a ride, I guarrantee you will feel a difference in the response to the throttle.
Costs nothing, makes you smile....won't give you 100HP but hey, its free!
