Hi there i really need some help. Ive finally got my sinnis apache on the road and on the way to the mot center there is a nation speed limit strip. Well cut a long story short i can only get about 45 mph out of it. I was wondering if there are any restrictions on them. I have a cone air filter and a performance exhaust on it. I am going to try a different jet in (a bigger one). If it is not that i dont know what it is. Has anyone else got anything else it could be if its not the jet.
Thanks for looking and will be great full for any advice.
