This customer bought us two Kwaks – his ZX-10R and ZX-7RR. We gave the later bike a post-winter service, swapped out all the fluids and checked the strength of his anti-freeze, which he was worried about (all was fine, though; his was good for between -7° and -10° C, OK for the winters we’ve been having lately). But be warned – bikes can freeze up in unheated garages if it gets cold enough…
Now the ZX-7RR was a rare beast in its day, never mind now. A homologation special for racing purposes, it has flat slide carburettors that work well at the track, at high rpm, but are quite frankly rubbish on the road at more normal speeds. The owner wanted us to have a good look through it, so we did, and found a nice, genuine bike.We went over it, gave it a minor tidy up, and then a quick run on the Dyno confirmed a power output of 115bhp, not bad for a 15 year old 750!
The Kwika Kwaka, booked in for a post-winter fettle...
...and its distant ancestor, in for a look over and a Dyno run.
