Thanks for the response,....it was actually kicking back coz the flywheel had rubbed through the stator wires and causing intermittent spark.......key was fine.
Somebody must have one of these....3r4 prefix....yz/it. 250/465/490 ....cash waiting.

It kicked back hard and put a large crack in the cover..... 
......I believe that this is a common cover between quite a few models....any help would be appreciated.

General Discussion / Road trip north
« on: February 10, 2015, 08:40:37 PM »
4 yrs ago , me mate arno (kraut) and I did a road trip up to Canberra for a heaven meeting,we had a realy great weekend, meeting new people,seeing how it's done on the Northside etc.
Just not to impressed with the track....but fun anyway( please don't take that personally nsw peeps)
Time for another.
So just a little ask for advise,....just a toe in the water.....what events do you have up there ,bearing in mind we love natural terrain, fast flowing types ...what would be worth while doing a road trip?
We are in melbourne and would like some other viper /vcm members to come with us.....who's up for it?

Cool stuff Nathan,I'd forgotten what happened in the 90's.
I'd sort of written it all off after disc brakes,p.valves,linkage sus etc.
Some of the stuff youv listed were important steps with the 2strokes that seem to be forgotten.
As you being a "young buck" you would know more about the progress during that period,lets hear more about that era.

Yamaha / Re: Yz465 h...why is my clutch slipping
« on: October 30, 2014, 06:04:15 PM »
HERE IS THE ANSWER........
The clutch pack in this bike is very generic between models 250/465 from 77-81...I knew that...and wrongly assumed every part was the same.....ohhhhh nooo......after a lot of head scratching i read the fine print in the parts list.......the springs are different between 250 and big bore.....it seems i had some 250 springs in it ( which measure up the same as 465)....some decent springs and all good.

Basket is very good condition.....pressure plate does have a bit of a wear lip on it hence the extra steel plate did not sit well against it....
Cable,operating lever,and push rod assy all seem good also......all a complete mystery.
However it seems to be ok now with the extra plate.....several clutch abusing starts up and down the street proved that.....neighbours just love me lol

Ok!...seemed to have sorted this...fitted extra steel plate in the middle of the pack.....
After looking closely the extra plate would not have worked at either end of the clutch pack, the pressure plate had a little wear on it and did not sit well with the steel plate.....same at the rear end of the pack.
Still doesnt explain why it slips when set up standard
?

Have tried extra steel plate (in different positions).....still no good.
All the steels are like new.......
All the fibres are old.....but as i said measure up ok...all very odd

Realy well done Shane!....the track was as ever superb ......the dust was realy not the best but more than tolerable.
I feel I do have to apologise for the spray i gave the track watering guys (think they needed a little supervision where they put the water) I'm sure they meant well.
Look forward to the next ASAP.
