Will have to book and get the cam chain and tensioner so back to cage/bus it is, FFS!!! FML!!!

turns out i'm working this friday night, soooo 0274054213

booking to get the tensioner etc is silly unless it needs doing

you may have fucked it, or the previous owner in japan already did for you, or there's nothing wrong with it at all

the zxr is still a better bike than the hyosung, imho, plus you've got a warranty and saved a bit of money buying it anyway... unless red baron really ripped you off

and incorrect clutch cable adjustment (and/or lever/perch) will cause similar problems

The trick is to get really dainty on your foot when going from first to second whole stationary..... Mind, conversely you have to be very positive while on the move.
A real pain when it jumps out.

As for oil, YES, ONLY half way up the glass....
The Race Bike (ZXR400) suffered a bit of a power loss, and clutch slip when overfilled... Ahem.

Duly noted QB, haha yeah have had it jump out on me previously when 1st wasn't fully engaged? so off at the lights I go and shoots in neutral l oops

Dang oil thing I didn't realise, decided to fill up fully due to one thing I was told that a bike is made up majority of oil?! Also, because my cuz siezed his first bike by not topping it up at all so was concerned more about that too, live and you learn I guess

No worries will drop a line anyways dude churrr.

Will leave tensioner for now as "I" may be the actual problem or better yet my riding/changing style. Last night didn't help as far as riding around is concerned as still have the mushy steez.

Yeah the zxr is mean ultimately I guess, the warranty aspect is only the initial 3mth warranty one.

Correct adjustment was done yesterday morning so am going to take a proper stab at this this arvo on the way home.

Ride to work was interesting, used the blipping aspect when slowing down...well more like slight revving as I haven't mastered the blipping part yet and found that it engaged and disengaged into all gears even 1st!!!

However, I was too chicken to disengage 1st and put it into neutral as I didn't want to have the same hassles I did yesterday but hey at least it worked which is what I'm happy about.

But!!!! A big thanks to all those that had input into the trouble-shooting, hopefully it's only UE and that my lil zxr is alll good, if it's just me then I do apologise in advance for my ass up

And that is why 99.9% of all bikes have 1st gear right at the "bottom" of the box.

Kave is right, bikes really hate shifting gear while nothing is running. You can actually break the selector return spring trying..... Had it happen to a CB400SS..... Yeah ,some body did it for us.

Plot thickens....
Now I think the gear shift problem is actually a symptom of something else entirely....
Well, sort of.
What i suspect has happened is your clutch cable has stretched, and you are not able to disengage it from the engine properly.

A little tweek on the adjuster may well rectify all, HOWEVER, ensure the cable is not being held on by a couple of strands at either end before thinking all is fixed.

I still want to have a look at it - call it a professional curiosity

Ahhh good stuff, makes more sense then. Selector return spring??? Ok, will have a read tonight about that too cheers

Ok, have checked the cabling to the best of my ability, and doesn't seem to have any fraying on the handlebar end as far as I can see. Hmmm, mushy gears this morning still as I got caught out at the lights lol hard to start in 2nd gear...again, dam things, makes riding more interesting especially when coming to stops!

Sweet... We can but try from behind the keyboard....
Let us know what is up with it... when you find out.

Cheers.

no idea what is the cause of the problem but there definitely is a problem....

maybe the ratcheting mechanism in the shift drum has been buggered around 1st and 2nd gear by learners not rocking it back and forth at lights, maybe it's a clod of gunky oil, maybe it's the clutch (which rattles when not under load and needs cable adjustment) or maybe it's the synchro that engages 1st and 2nd gear.... either way that's for red baron to figure out.

Also figure out how high that thing is meant to sit - methinks yours has been lowered for a short rider in the past but it might just be me
