I too just got an 46HV and the gain was tremendous. My friend who swears by his RWR Stage III kit was also impressed with the carb. We are (when time allows it) going to install it on his Stage III bike and see if any gains are there (will post on that when it and if it does happen).

The TM is less hassle to isntall than the 46HV. Tuning and the 46 will be easier than the TM45. You do get what you pay for. The fuel injection sounds really, really nice however the reliability is what concerns me. I saw quite a few Cannondales take a dump all due to the fuel injection system.

What kind of gains do you get with just fuel injection alone?

 

That is an excellent question. All of the information at the KMS website is still old holder info on the 400. Anyone know what the deal is with this website?

 

The -ONLY- real KMS website can be found here:

The other website that looks like it is KMS is not - it was some fluke and with any luck will go away after the registration expires.

Right now KMS does not have much online, so you will HAVE to call them for up to date info.
