Re: new member - first install - questions? of course
If you say that if you remove the chain from the engine output sprocket to the jackshaft and it pedals freely then the resistance is in your engine. As was previously stated they will be a little stiff when new. You could try adjusting your clutch a little. Turn the flower nut out about a 1/4 turn and see if it is better. Another thing that was mentioned earlier is that it will never be as easy to pedal the bike with an engine as it was without. Most of our customers do comment that they feel it is a little easier pedaling the bike with the Shift Kit than it was with the stock chain set up.
