I hate to leave a bad review for anything, so I'll try to be fair. First off, I think the price is a bit high but I want to support moto companies and I think the time and effort that goes into developing this product is valuable. Anyhow, this kit did not make a large improvement for my application, definitely not a magic fix. I already had all the pilot and main jets that came with it. The needles are what is special. Neither needle worked as well as a Yamaha needle that I ended up going with in my KTM. The hot, crazy humid, climate of Florida didn't work as well with the JD needle profiles.Read All Reviews
