i was hoping we could make a discussion post about different peoples methanol setups. like how you have eveyrthing plumbed in etc etc. what pet**** you using and how you installed in to the tank, the size and type of fuel line and where to buy it, quick disconnects, fuel pump.

trying to setup mine but not sure exactly what parts i need. was thinking a pingle guzzler 3/8 NPT inlet then screw it in the bottom of the tank i guess where the stock pet**** used to be and one oulet from the pingle in either 3/8 or 5/16 size. my pump is the black mikuni with 2 outlets so i figure i just put a T in it to merge both outlets together. not exactly sure where to mount the pump though. and maybe a quick disconnect or some other type of fitting just after the pet**** to hook in the purge bottle ? once you purge does the gas need to be drained back out of the carb or will it fire up next time with the gas still in there ?

I run the pingle guzzler but it still has the small dia. screen on it to fit the small hole in a Honda tank, I run a 3/8 npt guzzler on the snomoquad with dual outlets.

What I had pingle do on both my guzzlers is to give me a extra tall screen to hopefully help flow better if it starts to get a little crap in the tank.

I have also ran the standard pingle for the Honda with its really short length screen on both gas and alcohol, I cant say the guzzler has done anything for me except one less thing to worry about restricting flow.

I run I think is a 3/8 ID tygon tube from the fuel valve to the pump, and 1/4" ID from the pump to the carb. all my hoses are the largest that can be run on the fuel fittings and in fact are loose and need small plastic hose clamps to prevent leaks.

I run the Mikuni Hex black single inlet/dual outlet pump, You want to try and mount it behind and below the fuel valve but above the carburetor.
You should try and aim the vacuum port down ward so no oil builds up in the pump. You can also take the screws out and change the direction of the inlet and outlets in relation to the vacuum port that is part of the base plate used for mounting.
I have also had to in the past had to drill and tap the pump for a threaded hose fitting with a angle. if you use a angled fitting its best to just use a 45 so flow is not restricted as much, especially on the suction side
you do not drain the gasoline purge out of the bowl this gasoline will make the bike very rich when starting the bike next which is just like running the bike with the choke on and it will purge it out after a couple minutes of run time.
I bought the CPC inline white plastic purge valves but never used them because they looked to small, I just pull the hose off the fuel valve and hook it to my purge bottle.

I run tygon hose but only get 2 seasons at most and many times only one season, it tends to shrink some and get harder, I think the blue fuel hose works better but I think 3/8 is not available plus I really do not like the color hose.
I buy the tygon from McMaster

^^^same here but I still use the stock pet****. Same pump and all. I use the cast dual inlet bowl from CP. Which I believe rsss uses also.

i have the pump already. talked to packard about the billet bowl and he said its 2" deep from the bottom of the carb to the bottom of the bowl so i gotta check if i have enough clearance. but regarding the pump ill only have one inlet to the carb so i guess ill just put a T and connect together both outlets from the pump and have 1 line into the carb ?

on the 3/8" npt pingle did you have to slightly drill the tank hole bigger and then just screw it into the plastic tank with some sealer on the threads ? what do you think of a fuel filter with 3/8" in/oulet right after the pingle instead of a tank screen ?

udontknowme · « **Reply #4 on:** July 15, 2013, 07:11:51 PM »

anybody know where i can get the tygon F4040A yellow tubing by the foot ? every place i call wants to sell a 50' roll of the ****.
what i need is

5' - 1/8" ID x 1/4" OD
6' - 1/4" ID x 3/8" OD
5' - 5/16" ID x 7/16" OD

did you happen to notice if the hole in your tank was 3/8 " before you put the 3/8npt pingle in ? this one is 3/8" exactlly. i figure that should have enough material for the threads to bite in and hold securely. what do you think ? did you use any pipe sealer or that tape stuff on the threads ?

rsss396 · « **Reply #9 on:** July 16, 2013, 06:38:58 AM »

Yeah 3/8" is about right because when we were scrambling to get Troy's saber in a chassis I had a factory tank and factory valve that I removed to put a pingle on, I had both a spare 3/8 npt and the smaller Honda style, I thought about tapping threads into the tank but it was not mine.
The problem with the pipe threads in plastic is it may get loose and leak with temp changes or vibration. Alcohol is hard to find something that does not dissolve it or break it down

My snomo quads tank with a 3/8 threaded bung is aluminum along with the rest of the tank

any clue what needle this is ? heard alot of talk about pe1 but i dont know how to tell. also it measures 52.5mm from the tip to the base where it goes into the slide. does that sound about right for a strating point ? ?

rsss396 · « **Reply #11 on:** July 16, 2013, 10:13:29 PM »

mine is a pe1 but I dont think it matters to much because that groove cut in the needle is done by packard so what ever the needle was it isnt anymore
My needle is set at 50.5mm on the 50mm, but I run them rich

udontknowme · « **Reply #12 on:** July 16, 2013, 10:17:29 PM »

any idea what cable i need for a twist throttle on a bike ? the end where it hooks to the slide appears to be different than the keihin cables.

rsss396 · « **Reply #13 on:** July 16, 2013, 10:47:18 PM »

Packard builds them but you have to run a certain magura twist throttle

udontknowme · « **Reply #14 on:** July 17, 2013, 12:37:26 AM »

ok. the oem throttle on this bike is magura. does it have to be a special one or you think the one i got will work ? i can take a photo if you need to see it
