I just installed the Keyster kit and I'm having some real problems. The bike ran fine before the kit but the float needle was shot. I bought the kit and have since also purchased a #40 pilot since the kit comes w/ a #38. It runs on choke but not well and when the choke is removed there is a backfire through the carb. It also takes a while to return to idle when rev'd. I thought it may be an air leak so I replaced the intake manifold, didn't help. I have had it off three times now inspecting everything, it all seems right.I am wondering now if it's running rich and needs the needle lowered.

Has anyone else used these kits?

Is the jet really the size of a TK #116?

What needle clip setting have others used?

Anyone have suggestions on things to check/recheck?

1989 (all stock)

As many people who have posted on this board about Keyster jet kit problems with TWs ... . Anything a Keyster kit is supposed to do for TWs can actually be done with Yamaha parts for about the same money when shopping online.

I've had several TWs brought to me for repair after a Keyster jet kit was installed. Hope you didn't drill the slide per the Keyster instructions. It's an expensive part to replace.
