So my experiences with B12 Chemtool fuel treatment so far:  Perhaps the first time I poured in a bit too much in my 1 gallon fuel tank (I poured in nearly 7FL), but anyway, the difference was immediately noticeable! The product is a fuel treatment, carb , valve, and injector cleaning, and compression restorer; in clear liquid form, very chemical smelling (poison), etc.. My fuel mileage went up a bit, the compression definitely too, as accelerations became noticeably faster. At around 2k miles my TaoTao ATM exhaust wasn't making the 'put -put' sound anymore, but more like a 'zuz-zuz' sound (like someone describing a sewing machine). Seemingly the seafoam treatment didn't do a very good job in cleaning the valves! This product comes at $3,xx is about 1/3rd to 1/2 the price of a bottle of seafoam, and IMHO, it does a better job! Results are immediately noticeable! Don't know what else to say. Ow, I had about 1/4th to 1/8th of fuel left, did a fuel fillup, ran to almost empty, and did 2 more fuelups after that, and compression is still great (put-put, not zut-zut, or puzz-puzz). So, B12 chemtool! Try it out on your 2000-2500k mile untreated scooterengines! |

Yeah chemtool would be better for a valve problem I think seafoam is more a carb cleaning and gas stabilezer.

It's all I use as it does more than the SeaFoam. Seems to work wonders on all the engines I work on. Removes the gum and varnish from the carbs in only a few miles running....vice SeaFoam where it takes me a whole tank of gas.  |

In my opinion, just as long as you can keep the valves gum free, you'll reduce the amount of needed valve adjustments.
There are 2 reasons the valves need to be adjusted:
- The pins/screws pushing them down, wear out over the valves over time. It's a fact that can not be remedied but to adjust them every now and then
- There's carbon gummed up on the valves. The carbon causes the valves to close higher, resulting in the valves rubbing more on these pins/screws.
So by keeping the valves relatively clean, you could significantly reduce the amount of wear on the screws; and possibly delay valve adjustments.
Now, in the past I've used seafoam that seemingly removed part of the carbon deposit on the valves, however, after a while it becomes even worse than before.
What this product does is magic. I don't know what happens, but it's almost as if it removes the gum, and seals the valves again anew (puts a layer on them?)
One thing I've noticed though, and I don't know if this is related to the chemtool product, is that my scoot starts hesitating when it wants to accelerate.
Like the first 1-2% of the throttle goes fine, then from 3-10% it almost looks like the carb closes, and the bike will stall, then from 10%-100% (WOT), the bike seems to want to accelerate again.
I presume it's one of the butterfly valves getting stuck? (anyone else please chime in with a better possible reason why my scoot would do this).
Thanks!

Berryman's (B12) is what I prefer. Just watch out because if your tank is full of crud it could loosen it all up at once on you leading to rough running until you flush out the tank and start over fresh. Powerfull stuff which is why they have to put it in a metal can.

Sounds sorta scary to me..How many ounces should you put in your tank and are you sure it won't detroy your engine??

Berryman has been around for a long time....good reputation for quality. I have not used this product,...but bought a can yesterday at Autozone...$4.59+tax
Will add 1oz./gal...per instructions...today, when I fill-up.
Bike is running just fine now. May not be much of a noticeable change, if any, but I'll try it. Have been using Seafoam for the first 5k miles...no problems there.

Berryman's has been around for years and if you follow directions which are clearly printed on the label nothing will get destroyed. Basic rule of thumb is 1/2 to 1 ounce per gallon to maintain and 2 ounces per gallon to clear up a bad problem. |

I've added 7oz on a tank with less than 1gal of fuel.
The product gets burned just like gasoline does, and is itself (aside from a cleaning agent), also a sort of fuel.
Only thing I've noticed is, that the effects of the product start wearing off after 2 tanks.

[replyingto=prodigit]prodigit[/replyingto]It may take a few tanks at 1 or 2 ounces per gallon to get it cleared up enough to get to doing just a monthly maintenance treatment of 1/2 ounce per gallon. On most 49cc to 250cc scooters we are talking about 2 to 4 ounces per tank for remediation and 1/2 to 1 ounce per tank for monthly maintenance.
