The Thermo-Bob eliminates the inconsistent engine temperature and keeps it running at an optimal 195 degrees. Ultimately this leads to better performance and a longer lasting engine.

Good product -- Does what it claims.

Comments On Jul 03, 2012:Bought this from watttmann (the manufacturer). A little bit cheaper from him, but you will more than make that up with shipping over here.
Wattmann is a great guy. Answered my email immediately when I had a question. Instructions are pretty straight forward. Allocate 2-4 hours depending on how fast you work.
I started at 9 at night and I work slowly to minimize mistakes. I needed the bike the next morning so that wasn't the smartest move.
Anyways, this thing works just as advertised. Temperature needle moves nearly vertical within about a mile of driving, and will hover between 11 o'clock and 1 o'clock.
The product itself is quality too.
