Hi Jonrms, you'll need to change the forks too, as there is no caliper mounting point for the other side on the Single disc models, however here comes your problem... I'm pretty sure that the twin disc models use 41mm forks, instead of the 38mm on the single disc, so your gonna need to change the yokes too  i suspect its a lot of work for little gain in braking power, fit HH sintered pads and Bleed the system well, possibly fit a braided hose too. there's a thread LINKY HERE about changing the Master cylinder to improve the braking Feel. |

As above, to do this you would need the whole front end.
The brakes are fine if you fit a 1/2" master cylinder (ebay, maybe £20), rebuild the front caliper (wemoto £16) and fit (wemoto £10) Kyoto pads. I have been genuinely amazed by the performance of such cheap pads.
If you are anywhere near Portsmouth you are welcome to a test on my bike to see what can be achieved without swapping out the whole lot.

The twin discs use smaller rotors, give marginally better braking and add weight to the bike. The whole front end has to be changed so not worth the effort.
Talk to Amorti - he's the man with 600 brakes.

thank you everyone for your comments... by the sounds of it.. I best just get upgraded disc and pads.. thats what I thought but seeing as its going to be ripped apart this winter for a custom paint job I wanted to make the most of it.
Anyway I really appreciate your help and advice. I am also going to tune her up a bit... considering induction kit on the 4 carbs. will also want it ballancing and not sure but there must be a cdi on it.
I know its not a race bike but I want the best out of her... its going to be "hopefully" transformed into a show bike... and I just love tinkering!!! lol you seen my other bike.. lots of chrome etc... but its a cruiser... this one is a sports/tourer... so I want something special... lots of nuts and bolts... custom paint... performance upgrade... and well will see what happens as well.

Junking the airbox can be whole bag of headaches with carb jetting. You may never get it running right so best to keep all the old parts in case it has to go back to standard.
You could fit the twin discs but will need the whole front end forks, wheel, brakes and triple clamps. With all that hassle a Fazer front end would be a better bet and maybe even the rest of the Fazer to go with the front end.

what types of headaches are associated with removing the old airbox and installing induction kits on? I have done these loads but never on a divy... the front disc idea.. yeah I can see that being a nightmere... anyone wanna buy a front wheel with the discs and calipers on then? what other mods can be done to the bike... ie for speed and performance.... I know its not a racing bike.. but neither is a nevada and I modded the heck out of that just because I can... so really advice on mods... ie performance. do I remap the cdi unit. new coil packs... better plugs.. irradium . maybe change the front sprocket... exhausts..... whats out there?  ? please |

With the right sort of cash and kit you can do anything. However the Diversion wins because its flexible forgiving and not too sporty. You could easily spoil its good bits for very little improvement. Its great at what it does but if you want power and handling, the Divvie is not a good place to start.
The carbs are designed to work with the airbox. Take it off, the jetting gets all messed up. The main hassle will be finding tuning kits because no-one makes any.
Posh plugs etc will help but they wont do much apart from hurt your wallet. Its just designed as a mid range mid power engine so doing anything will be lots of hassle.
There are only one or two exhausts available and they will help a bit, but they are not performance parts and the original isnt "that" bad apart from rusting.
Gearing is a good compromise no point changing it
When/if thats done ok, the frame, suspension and brakes wont cope so the wallet gets bashed again. If you are really after more go, the Fazer is a better bet and keep the Divvie for everyday work.
Sorry to be a party pooper.

What they said - you will never get the diversion 600 engine to perform much better than it does. It's limited by so many things - it's an old tech 8v engine, with undersized carbs, a lazy cam, air cooling, a poor airbox design (that spout on the top does not make your bike any faster), bad gearbox ratios, etc. etc. etc.
But it is quite competent at commuting, and exceptionally frugal on fuel and tyres.
Best improvements to it that I have found so far, are to fit a 1/2" master cylinder to the single disc and hagon fork springs. As it stands the cycle parts on the d6 are already weaker than the weak engine. Before stressing them more, and ending up throwing it in a ditch, sorting out the cycle parts is a good place to start.
I've read you can fit a contemporary FZR600 rear wheel straight in and it will allow you a wider rear tyre, if you look carefully then although it's still not a common size you should be able to get radial tyres which will again massively improve the handling.
After that it'll start getting more expensive. And the gains relatively smaller.

I'd keep with some trick paint and as Amorti says, some sensible cycle parts. I'm not so sure about a wider front wheel. That, and a stickier tyre will just show up the back end which is limited by the swing arm.
In any case, a pair of BT45s suit the bike and dont cost megabux. By the time you've pushed them too far you'll already be in the ditch.
By all means trick up its looks, but the Divvie was never intended to be more than a workaday tool.

Thanks CD.
I like having things look nice and as far as performance I always try to push the limits.. this is just a bike for me to play with ideas till I get my harley... and that will be a couple years away sadly. I miss my old one. but moving on .... thanks again for the advice and I will of course keep you posted... pps look at the appologies section for some silly photos.. lol
