hello, i am on the lookout for a pair of zzr1200 cams for my better halfs(gail, by the way) 08 rex1200, she has had the air box removed and pods fitted with a dynojet kit but wants more horses and speed. currently running at 124hp. any help, thanks, bobby.
Thats a low output for those mods. You don't say if you have the stock headers tho'? This is the main restriction on the Rex as they are double skinned & have a very narrow internal bore. A bit like trying to run a marathon whilst breathing through a straw!!
You'll get 130 genuine RWHP with this done. A slight head skim together with some unshrouding work on the valves will gain a bit more but I can't say exactly how much as not had a dyno run since mine was done but i'm guessing around 135 or so. Certainly gained a lot midrange anyway which is where we mainly live.
If you haven't swapped out the stock header (doesn't matter what can you might have on the header, it's the header that makes the difference) for a quality aftermarket item, you have not yet reached the potential available from the pods/jet kit.
The stock system is also very heavy (about 30 lbs!) and a good aftermarket system will save you about 20 lbs in addition to letting the engine breathe properly.
Silver REXes are so subtle - they just slide under the target's radar, then WHAM! they're toast!
03 ZRX 1200R, Akra SS/Ti, Ivan's jets, K&N pods, Ted's advancer, chainguard and storage box, Chrispy's bar end mirrors, rearset plates, fork brace, 'n some other stuff. . . , 84 KZ1100R, 82 GPz550
we,ve not changed the headers yet, will get them ordered maybe at the nec if available, just thought i would send out the feelers for cams early on, when she had her 02 rex 1200 we put new headers and dynojet and got new kent cams for it, but it started to use i little oil when it reached the 90,000 mile marker, so she decided to go newer, cant seem to get kent cams for them now!

drack1: Hi, Question, I am rebuilding my ZRX1100-C2 I have just installed new bearings to the swing arm. Looking at the diagram in the manual the diagram I believe is wrong.
Jan 29, 2017 2:48:12 GMT
drack1: the diagram shows The top hat spacer fitting to be on the left. But it will only fits on the right side running throught the seal and upto the large ball race bearing. Anyone else found this issue. ?

drack1: dodgydal: The C1,C2,C3,C4 Relates to the bikes model year. Eg; C1 = 1997 C2=1998 C3=1999 C4=2000
