That "cork" should give it a bit more mumbo of the bottom....(like you'll need more go!)

I got the radiators rubber mounted. I used rubber isolators from JP cycles, less than $5 for a 3 pack(5/16"x24, fine thread). Much cheeper than the origional Husqvarna parts. Required cutting and fabricating new mounts as well as some drilling and taping. I also put some rubber grommets/bushings under the fuel tank mounts, to keep from having a problem arise later.
I had a few free minutes today so I took advantage of the latest drenching of rain. This thing is a blast in the slickery snot! It was a good training session on how to handle the big bore power. It was all over the place without having to get going scary fast. Invaluable!!! By the time I got done there wasn't a spot on me, or the bike, that wasn't brownish red.

good move with the rubber mounts...it probably feels better to ride even...

Yes fells a bit better. I am planning to fill the bars with rubber calking and bird shot at the ends. It still vibrates the hands on the top end of revs. It's definatly starting better and running better than it has ever run for me.
I got a tail light and headlight mounted today. Will post some pics when the rain lets up a bit.

I was able to talk a couple friends to go on a test run with me today. Got to ride for 11 1/2 miles on some bumpy country roads. she likes to run at about 75-80mph in high gear(5th). So cool to be able to roll on the throttle, in third, and pick up the front tire. I have yet to really open her up with full throttle but its plenty of fun without wacking it. I reached a top speed of 93mph. there was more stairs to climb, but with the condition of the road I felt that keeping at least one tire on the ground was a smart idea! I still havnt finished the rear fender strut and about 8 miles into the ride it managed to rattle itself loose. It didn't do any damage, just made a lot of noise(think cards in bike spokes), and got my heart pounding as I came to a stop. Anyhow it was a successful test run as everything else stayed together and I didn't end up eating any asphalt...
A video clip near the end of ride. rolling at about 25-30mph at start and ran up to about 75 with a quickness.

ripper allright...she sounds sharp

Thanks! It is having a problem revving down after a hard pull to high rpm. If I let clutch out it only comes down on rpms a bit. Not like throttle is open more like access fuel.. If I hit brakes and slow it down the rpms follow and stay down when I put clutch in. Seams like the vibrations are allowing extra fuel in??? I also notice a puff of atomized fuel comin out of the carb on each hard ting, ting, ting. I assume that means I need new reeds? After 8 miles I had to restart it. Wouldn't start with air filter on(uni). I took it off and it fired rite up. Put it back on and she didn't miss a beat. Noticed filter smells of fuel(probly causing a rich issue, or simply not flowing enough air from being damp)

sounds like a leak letting air in, find it before it seizes the engine solid

Dang! Not what I wanted to hear! I bet it's the intake boot if its anything!

That's the plan! Definatly not ponieing up $ for new rubbe one. Might try to build one out of metal to use a more modern mikuni boot. But that will be down the road aways.

So I tested intake for leaks and can't find any. The boot does have a few cracks but none to through. The way I tested was to fire it up and spray around the area of intake. It never revved up unless I spray around the inlet of the carb.
So what else could be causing it to only come 1/2 way back down after a high rev?
Also plug doesn't show any signs of a lean condition, actually it looks rather rich.

check crank seal under mag

I just replaced it but I will check it! Same test? Jut spray indie cover?

pretty much

I tested the rigt side crank seal today. Sprayed starter fluid around stator and no rpm fluctuation. Went over intake again and still nothing. Sprayed around the carb inlet(with air filter off) and it died. I'm confident that I'm not getting any unmetered air in around either crank seal or intake boot. Also sprayed around lower and upler jug gaskets and no change. That is a big relief! I notice the overflow tubes dripping a little fuel on those hard revs. I'm really thinking, the slow rev down, has to do vibrations. It's not so bad I can not live with so migt just let it be. Still think reeds need replaced tho.

Got rear fender remounted. Crimp lock nuts and locktight. Also tied tops of fender struts together. It will get layed down more flat once new tail light is mounted. Perfict day for a pic.

what a beast....nice work

what do you have going on for an air filter?
