If you have a Diversion 900, 600 or 400 this may be of use.
An American board suggested a 4 degree advance ignition rotor could offer a useful mid-range improvement for the Diversion 600. I looked for one in the UK but they only seemed to be available for the 900. Eventually I contacted CCDF Motorcycle Products who produce one for the 900 (and 400) and they produced one for me.
I have found starting and mid-range performance to be improved. This is not a massive improvement but is very useful and at under £20 is cheap and a very easy fix.
I have no other relationship with this firm but have found Dave Farnley at info@ccdieffe.com very helpful.
Ride safe
Brian

What does it do to the power and torque characteristics ?
Does it increase Exhaust temperature ?
Do you need to alter mixture ?
So many questions and only a marketing post.

If I was to suggest ways to improve the performance of any bike, I would suggest
Training, better skills will improve the performance of your bike, and it's cheap,
service, keep your bike well serviced, so it performs at its best,brakes and tyres especially
Diet and exercise, if your a tad heavy, then losing weight will enable you to perform better, plus less weight means brakes work better, acceleration is brisker,
then if you feel the need to improve the performance, more then suspension upgrades are favored,
of course having done all that, it's maybe easier to buy a faster bike!

I find wearing earplugs increases the top speed of the bike.  Probably because you get used to a certain level of noise. |

I have had no problem with exhaust temp and no need to alter mixture. At 65 losing weight is a bit of a problem but I did lose three stone some years ago when I retired but I agree it's better than trying to lighten the bike! training makes us all better riders but does take a while and doesn't necessarily combat an underpowered bike. On a pension, albeit a reasonably good one, I can't afford to change my bike, and I don't think £20 would buy that much improvement.
I would be very interested to see the torque etc figures for the bike in standard and modified trim but don't have access to a dyno!
This is not a marketing ploy, and it is very easy to be cynical, it is just something I found that I felt was a cheap improvement to my bike and you either accept it or... do the other thing.
Cheers, ride safe!

By the way, the logic of this is supposed to be ....
The XJ600 is a humble commuter bike sold around the world, even where petrol is not of very good quality, The retardation on the normal rotor is to deal with that. Since the fuel in the UK is generally good the bike can handle the 4 degrees advance without any problem. I have certainly had no problem with it and the mid-range is better.

It's a common way to improve low and mid range on more performance orientated bikes
No downsides as far as I'm aware - you should get a better burn and it should feel a little crisper
You can do it yourself with a file (at least you can on a ZX-9R, I can't remember the design of the Yam ones)
Will need no changes to the mixture, and won't make the motor run noticeably hotter - all you are doing is igniting the mixture slightly eralier.You just have to make sure it's not advanced *too* far

I Installed one of these at the weekend on my XJ600s (Plate £14 from ebay) must say for £14 I am happy. Not a massive difference by any means but for the price and ease its pretty damn good, the bike does feel a little more alive, very minor difference but its a difference all the same so defiantly a good buy imo.
Bit of advice if you do this! I found after trying various ways a C spanner will nicely hold the Timing Rotor to undo/tighten the bolt.

Was planing on putting bike in gear and having a helper hold back brake down to stop engine turning. Did you try it that way ?

I did yeah but still kept turning the crank more than the nut, admitting alas it was my girlfriend on the brake so I'll just leave that there, but I popped C spanner on the rotor and the nut cracked off almost instantly so may be worth noting if anyone struggles.

whats the fitting procedure?

Post by bigmick1981 on May 3, 2014 12:12:19 GMT
Timing cover case off , crack bolt and remover that holds timing rotor , slide off timing rotor , slide new timing rotor on with the 4 to the front , slide on spacer supplied with new rotor , put bolt back in , put timing cover case back on , ride and enjoy
Done mine today and Refitted my k&n , definatly feels more willing to pull quicker from lower revs

Or if you've got a 'rattle' gun, jobs a good un.  |

Dunno wot the place is coming to! Poor little tame D6. It's not meant to go quick. It's designed to potter around at a sensible speed, taking in the local scenery and stopping for old ladies at zebra crossings.
Timing tools for the Div6 indeed!
Ought to be a law against it.   |
