BGF 49cc rear friction wheel tank size?

[bilboby]

Hi,

Can anyone help in giving info on the gallon/litre tank size supplied with the 49cc BGF rear wheel friction engine kit. I've now gotton hold of a baby feeding bottle which has OZ & ml markings & thus will be used for measuring the oil/gas mix, something i didn't think of using before but thank's to you guy's i will be now.

73's & Happy MB Riding

Not familiar with that BGF or tank size.

HOWEVER, you should be able to measure how much the tank holds. Fill it to its maximum. Then place a large measuring cup below the petcock. Keep filling the cup until the tank runs out. Add up how many cups and voila! You know exactly how much fuel your tank holds.

This is the most precise way of calculating gas mileage. Fill tank and record its exact amount on paper. Set your odometer. Ride your bike all day. Then drain the remaining fuel into the measuring cup. Subtracting this amount from what you started with. Observe your odometer reading. If you used one quart of fuel and traveled 25 miles, then you're getting 100 mpg.

Hope this helps someone.

Cheers & once again from Motoredbikes.com a good reply but i don't have time for testing the logic thus have emailed ONCE AGAIN BGF for an answer, if they reply that is?

Okay, I have an easier way of calculating tank capacity. You WILL have time for this, because you'll be doing this on a regular basis.

Fill a 16 oz. measuring cup with fuel, and pour it into the tank. Not full yet? Then refill the cup and pour it in. It's almost full and you have 2 oz. left in the cup? Then your tank's max is a little over 30 oz.

If your fuel/oil ratio is 20:1, pour 1.5 oz. oil in, stir with clean swizzle stick and that's it.

I tried googling for tank size, but no luck. This way is "garans-ball barans" and hasn't wasted any time.

Then the next time you premix your fuel, fill your tank using the measuring cups. You'll then know EXACTLY how much your tank holds.

If you are choosing the answer from BGF over this site I question your sanity.
Thank you.

CQ...CQ Bilbody! I had a BGF F/D and it failed within 5 miles. One of my BikeMotorParts units now has OVER 700 miles. Good Luck w/ your BGF. The engine's not bad! Recommended fuel/oil ratio is 25:1. Do you still QSL or just use a cellphone? 73's

To store & measure the oil , I use one of these bottles that I have leftover .

Well surprise surprise for i have finally received a response from BGF concerning the fuel tank size sold with the rear friction engine kit. The tank holds just 1/2 gallon which is 2 liters thus for breaking in the engine @ 16:1 the oil mix should be about 125ml? I'm now aware that i was definately putting in the wrong amount of oil hence why the never ending problem with my MB. Once again thank's for everyone's help as it's the MB rider members like you that make this forum worth visiting and learning from despite my old age. Cheers & 73's

According to this,http://www.csgnetwork.com/oilfuelcalc.html, yes. 125ml.

So the e-mail you recieved confirms what is on ther postings on ebay. It is a 2 liter tank.
