Loctite is not bad at all.

I think you can change front sprocket. The motorcycle will be faster, but it will be have less acceleration.

Please write us what are the first 6 numers/letters of the engine number. 156FMI? 157FMI?

I had a different motorcycle with 156FMI and i have changed the front sprocket with god effect.

Important is to change the sprocket after 3000 miles. It is better for a new engine to have at the first miles normal (slightly increased) RPM.
