86 500 xc

Found a 88 430wr clutch hub on eBay...will it enter change? Looks identical but not sure with out measuring.

Here is a pic of my primary gear.

Piston and jug came!

Wasn't going to port it till I knew that it would run but couldn't resist doing a little! Ikno I have NO selfcontroll.
Intake side: knife edged the web, cleaned up corners radiuses and open up sour side a bit. Nothing major...yet! Left it in 40grit finish.

Exaust side: cleaned up casting imperfections and blended the step down goin into flange. Smoothed it to a 120grit finish.

Got the piston installed.

Back together.

Motor back in bike.

Compression feels a lot more like I remember from when I was in high school. Still have some things to do to the tank but did about everything else; carb: cleaned and reinstalled jets(390/30), routed electronics, plumbed radiators using mostly new heater hose, excep at top of head(3/4 hose didn't want to strech that much), clutch cable, re pack scilencer, ect.

That'll be my screen saver pic for the day thanks

Wildebeest, thanks!

Could have saved twenty bucks on the mirrors. Never had anyone behind me before on the back roads. Not sure if it's the speed or the smoke

Ha!!!

I hear you. At that point in time I though I was gunna have it dun in time to attempt a blast across the states...definatly don't need them now. Might install bar end caps instead, it will fit the "dirt chopper" image better than mirrors.

Got the bung for sight gauge welded into tank. Gunna hold off to seal it as the process take a min of 4 days. I got hear her roar!!! Went Shea and etched insde anyhow...don't want anything like rust or other derbies to find their way into my fresh and clean carb!

Gave Her 2 prime kicks then a good one...no fire. Immediately hit it again, ting ting to ting ting. Died before I could richen up with screw.
Guess I didn't preload the kicker lever spring enough... It didn't return all the way, basically strait up and down. Reached in to adjust screw...died and kicker lever kicked back and bite me! Son of a ..... It really hurt(s). Gotta love these beasts! Well respect them anyway!

Took her for a ride in back yard. Thinking maybe I shouldn't have ported it...it revs to the moon in a millisecond. Rattles everything, not locktighted, off. Rear fender didn't last a min before all mountain hardware was gone. Top of carb unscrewed, opening the slide. I hit kill button...nothing. Unplugged coil wire, got shocked, still running. Pulled the plug wire, still running!!! Finally ruled off air filter and choked her to death! All while coasting to a stop because nut rattled off brake leaver bolt New I should have waited till i had good front brakes.
Oh well nobody and nothing got hurt, and the adrenalin rush was worth it.
I didn't realize a 2stroke would diesel...was it because the top of carb opened up?

A pic before the rear fender removed its self.

I would never have made the long ride across the states....it puts the butt to sleep fast. No pad on the seat really lets you feel the vibes.

No offense, but that is some funny sh!t right there
An extreme lean condition will most likely result in a run away.
Glad you survived the test flight and hope to see some video of the project in action.

No offense taken Sure I would have been rolling in the dirt had I not been on it. Makes sense, with top of carb open lots of extra unmetered air gets in. Ill get a video next time I have someone around to work the camera.

Great story Nearly spat my coffee out. Don't think the porting work you did should have made too much difference to power delivery. My pipe is what makes mine peaky but your is stock I think? Even with a well balanced crank the vibes would be no good for long distance. With a full padded seat its bearable but on the road I found it rides ok enough before it comes on power, just to get around, but when its in the power it vibrates. Too busy hanging on to notice really though. I love the whole package, but only for an hour tops, I don't have that much adreneline left these days!
You should have seen my face when I found out what was the other side of the midrange flat spot my pipe causes. WWWWWWhhhhhhoooooaaaaaaaa
A video or your next Husky Rodeo please.

I went out to get a video and it won't run. Noticed fuel Leaking from the reed cage to cyl. The cyl was clearly machined to recieved a different reed cage. Look back at post #83... Leaks is caused because stock reed cage is barely large enough to cover enlarged opening. There are 4 screw relieves ground in top and bottom to clear screws.
So here is my question... What is/was the hot set up if one was to switch in a reed cage from another bike) keep in mind the 4reed top and bottom....
Researching reed cage the closest I can find by picture is a ktm mx350...the outer edges of cage line up with middle/top of bolt holes...stock is inside the holes...
Mabey Honda cr250 but all I'm finding for pics show 2r3reed not 4.
Would I be better off fabricating an adapter plate (basically just a metal gasket to cover oversized opening???

Mossbarger mabey???

thats wild, im not sure why anyone would do this? the husky reeds are readily available and pretty good size...definitely dont run it, thats for sure..thats a lean seize waiting to happen

On comparing to my stock jug is is only slightly larger. I don't understand why they ground it at all...especially the 4 notches top and bottom for reed screw reliefs. Went by local Yamaha shop...couldn't find anything close. They recommended using some yamabond. Ill putt it all apart in a bit and post some pics of reed cage ect.

Bizarre you could wack in some supa metal type putty (Belzona??)and then grind it out to suit. works on old holden cylinder heads...
