is there any larger fuel tanks that will fit in my mt2?

See post "Fun Factor Parts Links Here!"

There are links to a couple of tanks which need modificaton of the upper chassis plate to fit.

Cheers

ok thanks

OK heres the tutorial for fitting these two fuel tanks to your MT2 (will probably work with other Fun Factor vehicles).
The tanks are here:

Although these tanks are 125cc and 100cc respectively, they both have the same mounting dimensions, the only difference is the larger OFNA tank is higher than the HPI.

The front of the tank will mount on the upper chassis plate and the rear will mount on one of the upper plate support stays.I have included some pics to help out.

Step 1:
Remove top chassis plate and mark out where to cut as in pic 1.
The line is 16mm down from the EDGE of the chassis mounting hole.
Also remove the 2 chassis plate stays left behind on the left of the chassis.

Step 2:
Cut off excess material and smooth with file. See pic 2.

Step 3:
Drill mounting holes in the top chassis plate and the main chassis where indicated in pic 3.
Top chassis plate hole 4mm up and 20mm across.
Main chassis, 35mm across from bend and 40mm op from large engine mount hole.
Countersink hole from underneath main chassis.

Step 4:
Screw chassis plate stay to the rear tank mount hole.
Screw tank down and check for clearance between it and upper chassis plate, if you are using fuel tube to allow your tank to move slightly then make sure tank has clearance from touching upper chassis plate or you will find it may rub and possibly rub a hole right through your tank, dont be lazy and file some more off!!!
Now check the clearance between the front of the tank and the steering arm, you may have to file off a mm or 2. Dont worry theres heaps of spare material there as the outside hole on the arm is not used anyway. (Last pic)

Thats it, after complete installation you will have longer runtimes!!!

Hopefully I havent forgotten anything. Any questions just ask.

Cheers.

azzman! youda! you da man!

oh cmon now azzman - u could have given it a wash before u took the pics man, thats just disgraceful!

good work mate. bloody close fit innit! how long are ur run times with that tank, on average? im getting about 10mins from my MST-1 tank on the rally setup, about 7mins with the tmaxx wheels - dunno its capacity tho, its about the same as the standard tank tho.

oh - and does that tank u have fitted help to noticeably keep the front wheels down at all?

Ha ha, keep the front wheels down, yea right!! I have been using the HPI (100cc) so far and I havent got around to timing it yet. The next time I go out I will time both tanks.
Yea I could have cleaned it but...wel was in a hurry to get the post up!!!

ok thanks again, i'm not for sure getting one but if i do this will come in handy thanks a lot


cheers

woot thnx for this guys was just about to ask about getting a bigger fuel tank as the ones as stock are rather small

ya the stock 75cc is very small comparded to other company's stock fuel tanks

Timed it with the 100cc tank on (filled to brim) at the park, a mix of football field grass and concrete, was driving a mix of WOT and cruising etc and got around 14 mins. Stoked with that. Re-tuned and had the bottom end running a lot better and now its no prob to "wheelie on command", well thats when the SWAMP DAWGS hook up, it seemed to depend on if the surface had reasonable traction, the grass was damp n all.

how long can you carry a whellie for?

long enough to need to drop it down to steer! dunno really - too much time, effort and money in it to risk flipping it all the time.

the novelty wears off - trust me.

ok just wonderning, you have a good point don't want to destroy it

I bought the ofna tank and installed it last night. Thanks so much for the dtailed procedure azzman!!!! I just noticed when i finished that there is no place on the tank to hook up the exhaust. Is this not necessary with this tank or shoud i just make a hole and screw in the nipple from my old tank?

There should be a hole in the tank lid for you to screw one of the 2 nipples in that came with the tank....have another look dude, glad the procedure went well...

What did you use to cut chassis plate?

I must have bought the wrong tank or something becasue there was no 2nd nipple included and there really was no second hole anywhere. I endd up drilling one in and stealing the nipple from my stock tank.

I used a dremel to cut mine and a file to round the edges. I suppose a fine toothed hacksaw would work as well, or even a pneumatic cut off

Hacksaw works fine...
