Mods

[Kawasakifan]

Can you please tell me what mods i can do to my 95 zx6r to give it more power and grunt. is there any power commanders or chips available for my bike? Thanks

[Wattie]

hmmm

your bike does not have an ECU to which a chip can be attached to.

i suggest you get a jet kit before you go looking for a chip.

[Kawasakifan]

hi thanks for the reply i really appreciate it. is there different kits available or only one for my bike? and will that allow me to install the chip or will i need something else. sorry the questions probably sound silly but im new to all this. Thanks

ECU and Chips are for fuel injection, your bike has carbies, and therefore does not have an ECU to chip. A chip being a modded map for the fuel injection part of the ECU.

With Carbies you have to go the old fashioned route of changing the jets in the carbs, often reffered to as a jet kit. This not a simple process, and done right requires time on a dyno machine and a couple of hundred $$$.

Before you go that far, have a look at other options available to you for what you want to achieve.

Are you planning on riding drag strips, going to trackdays, riding in the hills or simply riding around town. In short, why do you need more power? Can you ride past the limit of the bikes capabilities? Are you finding a lack in acceleration, top end or mid range power? How much tuning has been done to the nut that commects the handlebars to the seat (ie you).

$30-50 will buy you a replacement front sprocket. Count how many teeth your present one has and go 1 less. This will greatly improve acceleration, allow easier monos but reduces the top speed. Note adding an extra tooth to the front will not make the bike faster as the engine will probably not have the power to turn the taller gear ratio in 6th gear.

Next step is an aftermarket slip on exhaust, expect $100+ used and upto 7-800 new dependant on brand, material.weight etc. This uses the bikes standard header pipe, but changes the silencer. Expect small gains in Horse power (3-5), excess noise and more attention from Mr Plod. No other mods will be required for this.

If you want even more power change the entire exhaust system - headers and silencer. This will be anywhere upto $1000 and will require alterations to the carborettor Jets. Normally this is done in conjenction with a high flow air filter (such as K&N). The exhaust allows air to flow out of the engine easier, the replacement airfilter allows air to flow in easier. Less work for the engine. All this extra air makes the burn lean (too much air, not enough fuel) so jets in the carbs are changed to put in more fuel. More air, more fuell = bigger bang = more power. With tuning, exhaust, filters etc, expect little or no change from $2500 if the exhaust is new.

You could also spend untold amounts of money buying lighter parts, which will improve power to weight ratio and therefore increase speed.

Spending the best part of $1000 on suspension word will make the bike go around corners faster, as long as you have the skill to make it turn.

There are a whole number of advanced rider courses ranging from 50 odd bucks to around $400 for Superbike School. These will teach you how to ride in a safer and possibly faster way.

Once you have spent all of the above (about $7000), you could go all out and have major engine mods done. Cams, cranks, clearences, polishing/porting the list is almost endless and the cost is high for a smaller return. It all depends on what you want.

I would say go the slip on exhaust silencer and the rider training.

Hope that answers some of your questions

[Kawasakifan]

wow, that answers all my questions. thank you so much for all the info you have given me i really appreciate it, the bike has a staintune muffler on it and i was also given the original muffler when i bought the bike i put the original muffler on to see what it was like, i did notice a drop in power not that much thou but it was noticeable. it is very quick of the mark and has no troubles lifting the front wheel, i just find that in 6th gear when i accelerate harder it seems to not pick up as well as it does off the mark, but this could be normal i suppose. considering what you have told me (Once you have spent all of the above (about $7000), you could go all out and have major engine mods done. Cams, cranks, clearences, polishing/porting the list is almost endless and the cost is high for a smaller return. It all depends on what you want) to do all that would cost a fortune, i probably would be better off hanging onto the bike as it is for a couple of years then maybe upgrading to a new bike.

Hey dude,

Your bike isn't fuel injected so it won't require a chip or PCIII (as Wattie said). If memory serves me correctly you've only just got this bike, stepping up from a 250? Do yourself a favour and put your money into something useful rather than chasing hp. You'll shave shitloads more off your OPH lap record with rider training, good suspension, decent tyres and more rider training than you will with an extra 5 (or 15) hp from your old 600.

If you really want to chase hp on a carbied 600 you should consider the following (roughly in this order):

- Jet kit. FactoryPro, DynoJet and Ivans all make reasonable jet kits; which one is best for your bike is often a case of preference - I like the FactoryPro ones. This will cost you about $150 to buy and another couple of hundred in labour and dyno time to fit and tune. Don't bother fitting one without allowing for a dyno tune, as arse dynos are horribly unreliable at best (see below).

- Ignition advancer. This won't give you much more, if any, additional horsepower, but you'll get better response down low. The arse dyno will tell you it made a huge difference because the power is where you might actually feel it. This will cost you about $60 to buy and another $100 to fit.

- Change your gearing. Again. you wont get any horsepower but the arse dyno will tell you it's become an instant rocketship. Costs about $250 for a chain and sprocket set, $100 to fit.

- Full exhaust system (you already have a slip-on, otherwise a slip-on would have been first). You'll probably loose low-down performance and gain hp in the top end. Again, allow for dyno tuning to take advantage of the extra ponies. Costs will vary from $500 to $2500 for the system.

- Race air filter. Not really recommended for a road bike but you will see a couple of hp gain. Do it with the jet kit or exhaust system so it's on there when it's dyno tuned.

- Open the engine up and go to town. Heads, cams, valves, ports, oversize pistons, high-comp pistons.

Now you start getting into really incremental and/or indirect horsepower gains. A 520 chain and sprocket conversion with alloy sprockets will save a bit of weight, as will light weight wheels disks. You don't gain hp this way, but you do reduce the drivetrain loss, effectively increasing your net rwhp.

You could go to town, spend shitloads of dosh and probably hope to get your 95rwhp 600 to pump out 110rwhp, but for the money you've spent you could probably have an or 636 making 110rwhp stock. Just a thought.

**edit: I see while I've been writing this epic Mike has said pretty much the same thing, but after typing it all out I'm going to post it anyway, dammit **

thanks heaps for the info, but as for ur advise and epic mike i think its better of if i stick with the bike in its currebt performance and i will be looking into rider training courses, once again thanks heaps

I used to race one of these

I agree with everything that the other guys have said, The big mods are filter (BMC not K&N), complete exhaust and jet kit. Get the Factory Pro jet kit over the Dynojet, easier to fit and no need to drill out the carbs. Get the ignition advancer, it won't add any HP but helps it get spun up quicker. Also junk the Clean Air stuff sitting on top of the engine. You need to re run a few vacuum tubes to ensure that the carbs don't blow out at speed. I can't off the top of my head remember what goes where but it is easy enough to find on the net. Then we could get started on braided lines etc.

Don't forget the suspension either. Being 11-13yrs old it is very possible that they are getting a bit old and lost most of their spring.

You can also drop a tooth off the front sprocket and add a few to the rear (really who needs 240+ KPH on the road). You should be able to get this done for under a grand if you shop right! I got a full Muzzy Exhaust for JC Motors off eBay for $550 there abouts, Filter about $100 Jet Kit $150 plus dyno time to fit, sprocket kits $150ish, Ig advancer $100ish.

The old ZX6Rs are a good piece of kit and can embrass the new bikes with a good rider on board.

Or you could just trade it in for a 10!!!!!(157 odd RWHP STOCK)

FYI Before you sook too much .. A mate of mine just spent a shitload on full zorst / filters / cogs and power commander on his 07 650 Daytona.
Spent most of the day on a dyno last Thursday to make 88RWHP!!!???? hmmmm the ol ZX6 ain't really that bad is it huh????

heh, thats what he gets for buying a Trumph Sports bike... Baaaa baaaaaaammm
