long story, hopefully short solution

[914359abe]

Wasn't able to ride last year, bad knee,  total knee replacement.
Tried to start the beast on a regular basis, but.........,   every time I tried it
was harder and harder to start.   Now needs some starter help to get going.
Got it going the other day with fresh gas.   It struggled to get going until it
warmed up.   Set it up to 2000rpm and let it run,   would shoot up to 3000,
then back down to 2K.  Took  it around the block,   it would struggle in 1st until
it got some rpm's under  it's belt.   Took it up  to  75mph  and it didn't struggle,
but it wasn't my old valk.
Big mistake,  one entrance to subdivision is up a 45degree angle,   I was sure I
wasn't going to make it up,  but it hung in there until I got to the top and then
power kicked in.   When I got home, shut it down and added carb cleaner and two gallons
of gas, started it up and locked it down at 2k  rpm.   Decided to feel the pressure coming out
of the exhaust;   left side-got too close, hot;   right side- cold??? followed exhaust to the
headers, touching all the way,  can hold on to the 1,3 ,5 headers and not let go.
Bike had been running for a good 10 minutes. 
???????????????????

Sounds about right. You have the classic symptoms of varnished low jet disease. It sounds as if the fuel wasn't treated before letting the bike sit. So, now there is a problem. You can try draining all the fuel again. Fill with new fuel heavy laced with a cleaner like Sea-foam and ride it. Keep the engine speed as low as you can and keep lowering it as it starts to run better. It may take several tanks. Or, you can get your hands dirty and spend some time cleaning the carburetors.

B-12 Chem Tool. Wally World carries it and it ain't super expensive. You put a whole can into tank of gas run it slow let her sit overnight and ride some more. Patrick hit it-clogged/plugged/gummed up slow jets. RIDE SAFE.

One of the keys to getting the slow jets cleaned up, is keep the RPM under 2,000, as above that you go into the high speed jets.

When a friend of mine let his Valk set for 4 years without and conditioner in the gas, it took 4 cans of Sea-Foam and 1 can of a harsh carb cleaner to clear it up.

The way we cleaned his up was full tank of fresh gas, 1 full can of harsh cleaner.

Let it run long enough to get fresh treated gas in the bowls.

Let it set overnight, straight up if possible.

Next morning, put around the neighborhood for like 30 minutes.

Add a 1/2 a can of Sea Foam. run it to make sure ya got a full snoot of this mixture in the carbs.

Again let it set overnight, the next day and overnight again.

Next morning  take it out & putts around with the tach BELOW 2,000.

As you are ready to come home, rap the Phat Girl out a few times.   This will force that mixture into the rest of the carb.

Drop RPM's to below 2,000 and putt home.

Park it for a couple of days.

This time out, play in all the RPM range, slow to fast, back to slow and up to fast for about 30 minutes.    Now go burn that tank full out.

Ride it almost to home and fill up again WITH a full snoot of SeaFoam.

Let it set overnight, take it out the next morning for a leisure ride.   Every once in awhile rap it out to 6,000  RPM's, hold for a few seconds and back clear off the throttle.

Add 1 full can of SeaFoam and fill with fuel.    Let her set and in a couple of days, you should be ready to boogie.

If this does not work get ready to get your hands dirty.
By that I mean pulling the carb bank.   Make sure ya got a full set of jets, just in case ya need them.   Most people say go to 38's, personally, I stick with the 35's.

Good luck.

If your plan is to treat the gas and let it sit

well, blocking the bike upright will definitely be a good thing to do.

Since it's the right hand side that's giving the trouble.

Seems like it's always the right hand side that gives trouble.
