Fredw has a split second as well at least thats what his posts say.I have the drop in kit in my 800r and am happy with it ,it has more power than stock,and runs very consistantly.My experiance with Rkt is have a little patiance and you will be happy,I had a few problems at first but Kelsey made it up to me,It isn't exactly a 8-5 type busness he does alot of riding/testing so if your instaling your kit and have a question it's likely you won't be able to just pick up the phone and have a answer that day, you may have to leave a message and he will get back to you ,this is were the patiance comes in handy,if this works for you you'll be very happy with his kit.I don't think I would recomened going with a mod like this unless you have a basic knowledge of 2 stroke engines,you can also send him your whole engine and have him build it and I'm sure you would have very sore arms and a big smile with any of his kits installed properly,with patiance he will work with you till your happy,I think he really knows his zhit and stands behind it.
My friend did the slp kit and it seemed to help,but you'll need a skimmer to pack your extra fuel.there jetting recomendation is like one up on the needle and 540s or something ,last time we rode he brought 2 ,5 gallon cans I brought just my 2.5 with my rkt. and he ran out about 10 miles from the truck
