  2. hello everyone ive just bought a thumpstar 120 pro fully road legal so i thought id join a forum to get tips and tricks about the bikes the main problem im finding is when im trying to cruise along at 40mph+ it pulls back as though its struggling to find continuous power could it be possible it needs a different gear ratio more top end speed less low end uselessness lol Any ideas?
