Kawasaki Sportsbike Riders Club - Australia - Online Forum

Lucky enough (I think) to pick up a 1986/87 GPX750R with a 'blown motor' for nicks. Turns out that the young previous owner threw away the air box and fitted Uni pod filters and a four into one but failed to make any jetting changes. Result...four badly burnt inlet valves.

Anyway, I've rebuilt the top-end, brakes and other bits and pieces and she's almost ready for the road. I understand I need a K & N Stage 3 Dyno jetting kit to get her running right with the current setup.

Does anyone know where I can pick up such a kit in Australia? I tracked one down in the Netherlands from GoParts. He wants 115 Euros (about $185 Australian) plus $105Aus freight, and a three-week wait. Sounds a bit steep to me. Any suggestions?

Also, I'm trying to track down an original airbox assembly. No luck with the wreckers or Kawasaki Japan.

Cheers

when i had a GPX750 I bought a dynojet kit directly from Serco in brisbane, i can't remember how much it cost either, so sorry about that.
the kit contains stage 1 2 & 3 in the one kit. I still have the stage 3 (and likely 2) jets floating about, but the new mainsprings and bits & peices are in my old bike, wherever she has ended up.

Also have you tried findapart.com.au for the oem airbox?
