Greasy finger nail week

[rictus01]

the worlds gone mad

well that's what it seems like to me at the moment, It's obviously "that time of year".

so far this week I've stripped & rebuilt an SV lump, removed and fitted a factory recon LC4 engine, and tonight just got back in from removing stripping an R6 engine, stripping a donor engine for the selector cam and one of the forks, re-assembling it all and refitting in to the bike, not bad for just under 4 hours work on a bike I had never worked on internally, Jason (owner of the bike) has to fit all the panels and give it a clean up though, but he now has second gear again.

Oh, and I dislocated my thumb doing it , but as it's been out before and popped back in no real damage ( bl**dy hurt though.)

Got a starter motor problem to sort and remove & fit the SV lump Saturday, looks like a whole greasy finger nail week then.

As I only do this as a hobby it's getting a bit much, I've yet to do a number of my own jobs.

Still all self inflicted, so I shouldn't moan (actually enjoy it most of the time).


Cheers Mark.

much the same only subsitute pub for up to elbows in oil & grease,not sure who got the best deal there

No seriously, it seems at the moment a lot of friends have bikes that are unwell in some way shape or form, or perhaps (more likely) they just want them sorted for the summer.

Cheers Mark.

Sounds like they should all club together and buy you a bloody heap load of alcohol to me.

:P

I'm just jealous

Mark..Curious that you were doing a repair to second gear on the R6,I know this is a common achilles heal on the R1 also. Those power wheelies take their toll! :P i

indeed, didn't want to say anything to Jason (as he knows I'm not that impressed with some of his antics anyway/ must be an age thing, him being half my age ), but looks like some less than perfect changes have contributed to seconds demise, although I can't blame him solely as it was a secondhand engine fitted before Christmas, so who knows what life it had before

Cheers Mark.

I know this might be a difficult question to answer but how many bad shifts does it take to damage the gearbox. Can one bad shift wreck a bike gearbox?

A bad shift can wreck a whole days worth of gearboxes but all those little Japs are happy in their work and never have bad shifts, unlike that lot in Italy who occassionally have a good shift and produce the odd bike that won't break down in the first 5000 miles

Any bad or sloppy shift can have the potential to cause a traumatic failure, however it’s not that likely, most of the time it’ll either go in or pop out without much damage.

Not engaging the gear correctly means when power is applied the “dog” (peg on the back of the selector fork) on the fork or profile on the cam will be force into place (which is what looks like its happened here) also it can put undue stress on the selector fork legs themselves, which at best will bent them (meaning you can’t select that gear) or brake resulting in broken bits of metal flying around inside your engine .

It looks like someone has been practicing wheelies and slapping between first and second, or exuberant starts without the control skills

A cumulative effect of excessive wear resulting in the bike jumping out of that gear.


Always worth checking second gear can be selected easily and doesn't pop out under load.

Hope that helps

Cheers Mark.
