Finally finished everything. Started it up. Actually started up real strong. But idles at a noticeably higher idle than normal. Could just adjusting the valves increase idle rpm. ?

TW's idle seems to move around a bit on a random basis, at least mine does....I just adjust it whenever it needs it.

Is this problem valve adjustment related?
Input appreciated: Have 5 riders in a Big Bear Lake TW200 riding club. All the bikes run fine except my 2012..
Situation: When coming down any reasonably steep off road hill in neutral at slow speeds (2-7) mph.
Symptom: Sometimes in Neutral she dies, and most times in Neutral the idle speed goes much much higher than regular idle speed.
As soon as I start approaching level ground the idle returns to normal?
This happens about 90% of my down hill riding time.
Bike has 639 original miles, use 87 Octane with Stabil, riding at 8000 feet of altitude, stock carb, stock exhaust, clean new plug ( did before new plug) clean oil, properly chain tension
Was told that they run lean anyway so no carb adjusting done.
Valve Adjustment, Carb Float, suggestions really appreciated

8000 ft might have something to do with it. Why do you run in neutral going down hill? (I might learn something)

Another thing. Going down a steep hill might shut off the float valve due to the angle. Make sure the carb vent is OK.

Original post: No, valve adjustment alone shouldn't change the idle. Warm up the TW. Adjust idle. Think about adjusting pilot screw to leaner.

2nd post: Downhill in neutral? Not me. I select a lower gear as required and use engine compression along with brakes as needed.

I think your carb float is sticking. Try Lucas Fuel System Cleaner or SeaFoam. Stabil isn't keeping up with all the crap they are putting in gas these days. Startron claims to "eliminate" and "neutralize" with "enzymes" the effects of ethanol. Lots of snake-oil but it does work. VERY expensive, tho.

It isn't "VERY expensive" if you buy the right bottle. One bottle treats 28 gallons and the same size bottle with a more concentrated mixture treats 128 gallons, but is only slightly more.

Deceptive marketing, sure, but one 8 oz. bottle of that 128 gallon StarBrite will last me three years or more: STAR BRITE 93008 STAR TRON GAS ADDITIVE 8 OZ#

Also at Walmart. You have to look carefully at the label, because otherwise the bottles look identical.

I use it EVERY time I have to use Ethanol gas, and over the winter even with Non Ethanol gas. I run a couple ounces of Seafoam in about every fourth tank. Carb continues to operate perfectly at 10,000 miles.

So while I was out in my pole barn I checked my bottle- 48 gallons. I like their math 1oz to 3 gallons of gas. So 3x8 is 24 how do they get 48? They retreat 6 old gallons of gas with 1 ounce. So 6x8 is the 48.

Dunno.....:confused:

What I DO know is that I bought the first bottle of StarTron on the dealer's recommendation, and it was something like $14 for enough to treat 24 or 28 gallons. Then I did some searching and discovered I could buy the 128 gallon variant for only about $10 online, or around 1/5th as much per treatment. I only use a capful per tank, and as I can still get Non Ethanol out here that one bottle may last 10 years..

I suspect they are in cahoots with the dealers to maximize profits from people who don't do their homework or don't care. I think they are different concentrations, because I have a little 1oz. bottle that stays in the tank bag if I end up having to re-fuel on E10, and it says 1 oz. per six gallons after initial treatment, and the 8 oz. bottle says 1 oz. per sixteen gallons. I don't remember the dosage of the original bottle I bought five years ago.

Of course all this could be total BS, too.:mad: I'm going to use it anyway!

I'll look when I go shopping at Walmart. I knew they had it but it was same price as my hardware store, but I didn't check the mix.

My last 8 oz. bottle of Startron cost $8.00 (in round numbers). If it treats 48 gallons it costs 16.7 cents per gallon. I can buy non-ethanol 87 octane for only 10 cents more per gallon (hard to find though). I can not find the 8 oz. bottle that treats more than 48 gallons.

Interestingly, when I put it in my 2006 Ford F150 5.4 L V8, it increases mileage from 16.6 with 87 octane ethanol gas to 18 mpg. If I run 91 octane non-ethanol I get 18.5 mpg. Price comes out very close to the same.
