yz465 parts...

[Glen08]

Wow thanks mate , I appreciate the info 

At the moment Im trying to get it all together & work from there..Did the static timing today , still no W-key so I went fishing in the other shed & found one off a mx80 that worked for that....

Swing arm came apart well , not so well the lower shock mount,,,ill get it !

Flywheel key is common to pretty much all yamahas from then on, check out this list

My lower shock mount has some play in it, if I grab the rear wheel there is movement inside the mount. From what I've seen I'll have to get a new pin made up & possibly new sleeves in the swingarm.
The all balls/moose racing kit for the 465 fits well apart from the seals in the covers which are too big, I ended up reusing mine & have picked up a pair of the correct ones for when I paint the frame over the break in the series here
If you need to heat the pin etc up to get it out the bush for the shock does show up on ebay & is listed as being available as well as the thrust washers, the pin isn't though

I have a length of 1/2 inch stainless rod ,I cut a piece long enough to put holes in the ends for a split pin, then with a good battery drill ,drill a 1/2 inch hole through lower shock mount and swing arm (this can be done on the bike)with cutting compound.
I have done this to my yz d and yz h with good results

Thanks guys ,
 I have the 250 roller & its swing arm pivot points are good & free , however Im reluctant to use the 250 stuff unless I really need to, I must say im much more at home on a Suzuki 

I need to get some pics up but I think I need a new computer & haven't had much luck uploading 

I have an issue with the rear side of the main down tube on the 465 frame,..A couple of inches from the bottom of the top gusset , the structural re-enforcing has  been removed all the way down the main down tube except the mount for the shock reservoir , its been left in tact,,,,,the thing that has me baffled is that its a neat job ,,,,,if this makes sense was it a frame flex mod or for a different expansion chamber
ps I can email pics

Airboxed off the list.....missing the filter cover , but Ill cross that bridge when I get the box...

Pulled the clutch back off after reading more about these bikes, to find.......yes the pressed on gear behind the clutch basket hass dislodged itself ,,,, I have another one ill check today if its ok ,,,can the pinion gear be welded in place or should I address the issue with a later model 490 clutch & crank gear ? Thoughts please   

                        regards glen.

I have had them repaired .he welded three spots on the high side of gear tooth , after first cleaning up the damaged part and pressing back on flush with good results ,you have to check inner sleeve as welding made them tight, he also fixed

[Glen08]

That's the go,,,uni-filter bulk order 

Well the other clutch is worse..Looks like ill get a good one out of it all ,,,,,if I weld the basket...

You can buy new billet clutch baskets from the UK. Check the older VMX mags for the guy

I have one and its grouse

[Glen08]

Thanks Ted,,,,lovely job on the yz by the way!

That sounds promising,  I'll look into it,  I'd prefer to keep the original box if I can...both kicker shafts have been repaired aswel which doesn't  surprise me,,,
I'm enjoying it regardless.

[Glen08]

Wanted some thoughts on the inner clutch bearing,,inparticular the bearing collar,,,I have one that's usable but the other has signs of being to hot,,,my question is can or has anyone drilled a hole in theirs or can a later model sleeve be used??

Ps,  I Realize most of you guys have answered these questions before,  on top of already putting the hard yards in!!!
So I appreciate any & all advice,  cheers.

[YZ250H]

both kicker shafts have been repaired as well which doesn't  surprise me,,,

The fix for that is to throw them over your left shoulder and get one from a K series.  YZ250K replaces YZ250H.  I think 250 and 465 have the same kicker shafts, but worth checking before you rush offto EBay  .  Apparently you will never break that one.  It's manufactured differently.

[Glen08]

Copy that YZ250H,,,,going over back shoulder now

[Glen08]

Ok.....just got off the phone [Wreckers] & the 1st chap says the 81 airbox won't fit the 80 , to which I agreed, then proceeded to cross reference the two ,as you guys know different parts numbers, I also read [thanks to this forum] that the 81 is slightly bigger.

Then 5 min later they call back saying the 81 will fit the 80??

Wondering if I should buy or not,  mine is the 1980 frame...

[Glen08]

Bought the air box,,,, they were nice guy

the YZ250K kickstart will interchange with the earlier YZ250/465/490's, but the YZ250K kickstart is angled forward, very short and hit's the foot peg earlier.
the best kickstarter to use is the 1981/82 IT250 H/J version, these have a dogleg which allows the kickstarter more than half a turn before hitting the footpeg. i used one on my YZ465/490 engine, basically you get 2 sparks per full kick which makes starting the bigger engine a lot easier. these kickstarters are obsolete but can be found, be prepared to pay a fair bit more for a good one though...
