1984 WR400 help

good idea. thats what it had before (M8) but the new mounts are 5/16-18. i just ordered some stainless nylocks. thanks

Is this the fill line? If so I have previously had it way over full....

Can't find much in manuals because it says see technical data sheet.
Found in surprize's thread I should be 1.7 qts.

I think you may find that is Litres, not Quarts !

I am sure they take between 1.6 and 1.7 litres.

I put 1.4 Litres of gearbox oil in all three of my '87 LC bikes. With the bike upright the level should be just under the filler 'tube' above that upper 'rib' thing above your finger. All three bikes initially eject some of that fresh 1.4L lube out of the breather in the top of the clutch cover during start up, go figure

too thick of oil if you are ejecting out of breather...my bikes seem to do that with bel ray gear saver. has never happened with atf or motor oil

I know. I converted and they are the same.

So I was definitely over full before. Any chance that was help the clutch slip or (more of a stretch) the top end power loss?

Not really, it runs in oil regardless, the quantity will not make a difference, top end power? Only if you have a leaky crank seal sucking oil into the crank case, but you'll have a thick plume of smoke behind you that you just couldn't miss.

Have you taken the old girl out for a run ?

and get paid by the city if you add whatever Mossie control to it..

Mossie control?

I didn't ride it yet. I was going nuts the last 3 days building a large rock wall hauling rock in buckets down 2 flights of steps. Not to mention it was 25 degrees f and lightly snowing today. I'm now home but should be back with the bike mid week for a very abnormal 65 degree day wednesday. Its normally how it was today this time of the year. I'm excited to try she's ready to go though I suspect I'll need to alter timing again.

just a tip, I found a rear frame damper off a Honda 900 is ideal for the husky exhaust. Honda dealers are like maccas,one on every corner.

haha you guys are funny! i had to look up "maccas". im still wondering what mossie control is though.

do you recall what year cbr 900?

Mossie is slang for mosquito.

hahaha awesome. ive never heard of such a thing around here. (not sure if this happens down unda or if it was a joke).

test drive tomorrow. will be 25-30 degrees f above average.

It's only a joke when you see a swarm of the bastards above one of your mates asleep when camping!

Haha got it!

So test ride #1..... it started in like 5 kicks. Not bad for having all that apart.

Idled and revved well. See video. But when I took off I only got about 100 feet til I got high in first gear and shifting into second and I got a backfire and it stalled. Timing must be off?

Looks like I shared the flywheel key within 100 feet. Maybe I didn't work in enough I definitely didn't use a torque wrench butt torqued it down pretty tight I believe with rope in the cylinder. I guess there's a chance I forgot to torque it at all it was loose and I pulled it out by hand just now.

Lap the flywheel onto the shaft with some fine valve grinding paste, new key, torque up and away you go again.

Yep you gotta lap them.
