I just picked up a decently clean 91 kx125 for a bike build and wanted to get thoughts on reeds. As with most older kawasakis ive found the rubber air boot coming off the reed cage has some gnarly dry rotting going on and it will defiantly need replaced. An OEM rubber air boot for the carburetor isn't available but I have found one guy on ebay selling a reproduction (part number 16065-1206 from hotfootmoto-online). If any one has experience with these feel free to share. Then there is the rad valve or v force route. Ive been told good and bad about both but most are peoples opinions on newer 125s. Some people say they are great, others say they are a pain to get your bike to run half way decent with them at all. What are your opinions and experiences on these after market reed cages for these early 90s 125s. Thanks

I've run both, Vforce was more low/bottom response with stock top end pull and the rad was more everywhere but not as good as the Vforce on the bottom/mid.
Can’t vouch for the V Force. The rad valve has been on since I was 16, i’m 42 now 😂
Has always ran crisp and pulls well.
I always go with Boyesen for all my reed needs.
SLOWTIME sent me some awesome info from Eric Gorr on his recommendations on a 90-91 kx125. He says the best value modicafition for this bike ironically is a boysen rad valve. His recommendations on jetting is air screw out 1.5 turns, stock pilot jet, stock or one size bigger main jet, a slide out of a 1990 kx125 or kdx200 (CA6 slide) and N84C needle. So needless to say that'll be the set up im going to try and we will see how it works out.
