DIY home service

Replaced the spark plugs,syncronised the throttle bodies starting to get better at it, and made my own clean air mod. Took it out for a blast and it is like it had its steroid injection. There is a lot less back firing on hard deceleration now. The clean air block off's are vaccum hose and I super glued the ends I used a good quality glue. I also changed the oil and filter used Motul synthetic 7100

whats the go with syncronising the throttle bodies on a fuel injected bike?

or am i asking silly questions??

yeah dude, fuel injection only regulates the quantity of fuel being injected (though admittedly they dont do it per-cylinder, they just all get the same dose), you still have to make sure the carbies are synchronised in how much air they allow in.

You will be suprised how quick they get out of sync. Thats why i do it every 1000km or there abouts. It smooths your throttle responce. Now i understand why so many bike mechanics forget missing screws on bikes. Thats why I do what I can myself.

hmm sounds like u had fun..hehe

motul 7100..thats the full synth?? i think ive got 8900 or sumthin in mine?? dealer put it in...

Yeh its full synthetic it is the one before the race blend.

no silly questions, only silly answers...........

....you still have to make sure the carbies are synchronised in how much air they allow in....

pretty much spot-on - what you will be synchronising are the 'throttle bodies' - the butterflies that open up when you give 'er the berries.......even a small difference between cylinders can make a large difference to how smoothly your motor runs, idles etc.

old mate aus636 has the right tools for this job, the mercury balance tubes are the most accurate way to measure 'carbie' balance (or EFI balance )......

It takes about 15 minutes *max* to balance the slides on a Kwakka 9 !

Which reminds me Gos, you don't happen to have a set I could use if I pop around this weekend do you?

Indeed I do........does the Bullet need a balance ? It sounded pretty good the other week...

Top job aus636 I am impressed! ... I have only ever used mercury balance tubes on carb bikes & this is so logical but not something one would think of doing as part of basic home maintance / servicing on an EFI bike

Excellent Smithers....I reckon the number of times I've had those carbies apart they probably could do with a check over...and like you said, it doesn't take that long

I also notice a great improvement with new spark plugs so for the cost $20 they are another item that will be change more regularly. The next major task for me will be to check the valve clearance but then again the service book says 42000km. And you know when paid someone to do what I just did it cost me $360 and they still F%$#ed it up. Thats why i try and do what i can and if i cant like shocks I will the remove the shocks and take it to a pro.

Did you go for the OEM plugs or change to different ones?

Some people said try the iridiem plugs but i just stayed with the NGK and they seem fine. I have spoke to some people and they say if you plan on doing regular service just stick with the standard plugs.

The vaccum gauge tubes are stainless steel sliders they are made in England and the beauty of them unlike the dial gauges is they dont need to be calibrated and it is easy to see each throttle bodies vaccum.
