Its on now, makes a bit of a funny noise (chain clicking?) which was worse when i tightened the chain so i guess i'll loosen it 2mrw and see if that makes it better. Sprocket has a tiny bit of a wiggle but it did that with the old one 2, when i put it back on to check.

Doesn't seem to make a hell of a lot of difference yet. Getting dynojet kit monday so will hopefully be able to tune it even better.

Thanks for all the help so far guys You're all so much more useful than the manual :P

OK, I'm running a bit late on this, but anyway ...
Don't worry about the o ring, you don't need it, it's just there to cushion the chain to reduce some noise so the bike can pass the noise test in Oz same goes for the snorkel on the airbox.

Stock gearing is 15/41, I changed to 14/41 which was better, but as you say not that much better, so I changed to 13/44, that's much better off road but it knocks your top speed back a bit.

I took it out for a bit of practise today. Got feet scraping around a few corners then headed to a carpark to scare myself doing tiny little wheelies 20-30cm mayb. It does make a bit of difference Easy power wheelies in 1st and bounces up alright in 2nd. Now just need to keep practising and get the technique and nads in line to get them higher and longer

Dynojet kit in now. 155 main jet and 4th slot on needle as box recomended. Also took out backfire screen. Mixture about 1 1/4 turns out. Runs much nicer now. Is quick and smooth all the way, front comes up easier in 1st (still not doing it off power in 2nd) and got to 100 where i usually only get to 80 on my test run. Hardly any popping on decel either

Also got some new plugs. CR9EK. Slightly hotter i think with dual spark. Found it on thumpertalk. That should hopefully make it even quicker and smoother. Just cleaned off current plugs and gonna run them a while and see if im to rich before i ruin my new ones

Same temp as stock I thought?
Running them in mine and didn't notice any differencce really but I'm not pulling them out just in case
If it was summer I'd have got the CR10EK but the 9 should be sweet as we don't get extremes of temp here.

[Mole_C]

Thought stock was 10? Oh well, even better news for me then

[NordieBoy]

The 10 is the coldest NGK plug.

[Mole_C]

Not much but its a start

[NordieBoy]

Cool.
You can only just see the wires holding it up

If it was mine you'd be able to see the scissor jack holding it up.......

Spark plugs: according to manual (of slightly dubious parentage) stock plugs are CR10E and hot type is CR9E.

Manualles never lie

I wouldn't see the need for a hotter plug unless a lot of low speed running / low load or friggin freezing weather was anticipated, am I missing something?


APART from my toupee.

[NordieBoy]

Hmmm, my manual used to say the CR9E was standard but it agrees with your manual now...

The CR10E is the coldest NGK plug so the 9E or 9EK isn't much hotter.
Hmmm, I may try the CR10EK's soon to compare with the CR9EK's.
See if there's a perceptable difference.

A real pleasure to read all the advice on this site. I have D/Jet needle & 150 jet ,needle on 2nd groove from top [ 4th far to rich @ +120kmh ], top cut out of air box, stock exhaust, 520 chain & sprockets, 15/44, this bike acheived 155km/hr over 800m on a sealed airstrip ,using GPS readout straight after the 1000 km service totally stock standard. Cheap fun !. I have not had the chance to have a run since mods. Bike is just so smooth to ride now especially at low & road legal speeds,will even run smooth @ 50kmh in 5th gear ! Many thanks GAZBUR for your encouragement @ Wymdam street races, I was the other DR rider @ Teretonga. Many thanks to FRAN for advice re bike & computer direction to this great forum.
