Andy are you running motor forward or rear?
being honest with you it was the first time I run the engine in the rear, and being honest I didn't think it would work,,,, but now id not go back to the forward spot again,,,, engine is well clear of the fuel tank even if your bell came loose, it even jumped flatter in the air no more noise down was a real joy to drive, and every person at the track made a commit on how much rear grip I was able to get compared to others well well happy I tried it and never look back now, you are also able to run with less droop front and rear, and it means no more messing about with it when the weather turns wet, just able to run it the way it is wet or dry, I will try and get a set up sheet sorted for you all to view
