any tips for tunning my ds with alky? i have an airfuel guage on my ds now but dont know if it will work with alky. what do you look for as far as being lean.

 

Correct me if Im wrong but I think alcohol would burn up a O2 sensor so a air/fuel gauge would be out of the question. Also alcohol works at a different ratio than regular fuel which is 14.7/1, so if the gauge actually survived the alcohol then it would constantly read rich since twice the amount of alcohol is used compared to gasoline. If anyone sees anything wrong with my thoughs then feel free to correct me as I am no expert in alcohol or methanol.

 

I also heard that if a alcohol bike bogs at any rpm then it is running lean. O yeah and dont count on reading plugs to tell you like a gas motor will.

 

I'm VERY new to alky myself. But from what I understand your plug should look brand new if it is tuned right. I think any tan color means lean or rich.

Like I said, I'm a noob to alky, please correct me if I'm wrong!!!!!

P.S. I don't see anything in your sig about an aftermarket carb, I don't think anyone has had much luck running alky in the stocker.

 

i am running a jr drag carb that is set up for alky.

 

is it possible to run fat on alky?

 

If you run too fat on alky, your power wont suffer than much,but you'll notice your oil will become "milky" The best way I can think of to tune alky is to get a ETG(exhaust Temp gage) and jet by reading exhaust temps. I think the best exhaust temp(at the headers) for alky is 1250 degree's, if its to lean the tempature will be higher,and vise-versa. Someone on here will know better, but I think thats right.

Your throttle body will come pretty close,but remember. It "tunes" alot different than a regular carb. WE have fuel pressure as a tuning tool,along with jet size. It will take some time to get these tuned in perfectly,and their isnt going to be much info here. Darrell is our best source for tuning info, and also trail and error is going to be the best way to tune your quad in the end.







Bigger.

 

im looking forward to getting it. he sounds like a nice guy and told me to call him night or day. im sure ill get it dialed in. bigger what compression are you running. i was going to 11.5:1 but i was told to run 14:1.

 

also how would a 14:1 piston work with alky and stock cams?

 

anyone running 11.5:1 with alky or do you have to go 14:1.
