Felt MP

Felt MP link

hate to ask, i read a post in here and it had a link to a felt MP frame all cut up. he cut it up to seal the holes in the frame. i cant seem to find it again. can someone post a reply link? TIA.

http://www.oroville-eternal-riders.org/motorbike.htm I believe this is the link you are asking for. The Bike shown was built by member itskeith up in Chico CA. It is possible to seal up the tank with epoxy products. Member HBLOCAL has done several Felt bikes this way and seems to be willing to share his method. You might want to try PMing him. His bike is the Felt 1903 linked too in several threads here.

One other note the MP bike itskeith used was an aluminum frame. I believe the version of the MP you are getting is the steel frame. For some reason Felt switched the MP to the Steel Frame. The volume of the Top Tube/Tank is smaller/less on the steel frames.

grezmonkey: I have seen these MP bikes and they are sweet. I did a couple of Nirve choppers and used the big top tube for the tank. You should be able to remove the fork and get to the weld hole in the head tube. As for the back of the tank, any place that another frame component attaches you will find another hole to fill. These holes allow for heat and gases to escape during the welding process. You can cover with tape (headtube) or use a very small amount of expansion foam to temporarily plug the holes. Once you drill and tap threads for your fill, vent and petcock fittings, you can seal these holes permanently with some fuel proof RC aircraft epoxy. I used a medium sized syringe from Menard's with a piece of clear flexible tubing through the holes for the fittings. There is a fairly detailed post by Blaze if you can find it on here. Good luck. I think you will have a VERY nice motoredbicycle. Peace!
 
thx scully, thx billy

I wanted those pics to see the seat post area. i noticed the tank kinda wraps around the seatpost and didnt know what it looked like inside. was thinking jb weld all this time to seal it up, but wasnt sure how i would manage to reach in and plug it up. didnt even think of expanding foam. THANK YOU!!!

i dont mind the smaller tank capacity. Id like to find some saddle bags later and hang them from the rear rack. leather, canvas dont know yet. maybe even metal, it would be something to keep in line with the theme. Im sure i would have a squirt bottle of gas in there just in case.

AMMO Boxes would be fitting with the theme. Try your local Army Surplus Store.

A small amount of expansion foam would seal the hole TEMPORARILY till the epoxy sets up. It is not fuel proof! Just wanted to be clear on that. Peace!

Glad to hear someone else is going to use a Felt Bike w/a motor the frame does not have to be cut up in order to seal the holes on the frame.
I will go over the process I have used on many Felt bikes very briefly

yes i have done the MP bike first I disassemble the entire bike then wrap the frame twice with ten mil plastic to protect it from accidents.
I then drill the fill hole and the petcock hole where I would like them placed after that I tap the holes so I can install the valve and nipple I use for filling the tank do not install until after the tank has been sealed.
On the head tube you can use pieces of blue masking tape on your fingers and reach inside the head tube and cover the two holes from the inside the third hole you can only get to from inside of the tank your filler hole is how you get to it put a piece of tape on a screw driver or something small enough to fit into your filler hole and gently cover the hole it is very hard to see the hole use a flash light .
Once this is done hang the frame w/the head tube down you will need to go to pep boys and get some J.B. weld you will need the "INDUSTRO-PAC" take the J.B. weld and leave it in th sun for twenty minutes so it will heat up and become plyable then mix up half of the tubes and put in a small hypo-dermic injection tube and then fill up the inside of the tank w/ J.B. weld roll it slighly back and forth to complete cover the holes inside check for leaks let dry over night.
The hole in the seat tube is a little harder to do but I have done many and so can you again put a small piece of tape over the hole on the inside w/ your finger get some fine steel wool and twist into small rolls and insert into petcock hole try and get it to both sides arournd set post as the back of the wish bone on the frame is also not completely welded and will leak down to the rear axle hanger.
Use a small piece of hard wire or a bent screw driver to pack the steel wool in place very important that u spend some time doing this to insure that the J.B. weld you are going to inject does not leak thru to the bottom hanger.
Once this is done hang the frame w/the head tube up and again heat up the J.B. weld and inject from the petcock hole use a flash light to see how much u are injecting keep the J.B. weld about and 1/8" below the petcock threads and keep the threds clean .
Keep ckecking to see if the J.b. weld is at the level you left it if it goes down that means you have a leak thu the steel wool and you will have to re-pac if it does not go down then you have sealed the tank successfully and are ready for the next step,but before you move on do one final check by filling the tank w/water if it does not leak out or go down you are ready.

You will have to go to a motorcycle dealer and get some tank sealer called " CREME" it is a three step process which consists of degreaser acid wash and the actual sealer itself.
follow all instructions on how to use the sealer this is why you wrap the frame in plastic this stuff is very toxic and will ruin paint etc.when you are using the acid etch do not plug off the tank completely as this will cause the pressure to build and it will blow out all of the acid and you will have one big mess.
After you successfully gone thru all of the steps let it dry for one week before putting any fuel in the tank after that you will be ready to assemble the rest of the bike as for the filler tube on the top of the frame I use a threaded 1/2" brass nipple w/a cap on once this is installed I will paint on a thin line of J.B.weld around the nbottom of the threads to ensure there are no leaks there.
This is how I do it in nut shell and it has worked very well and until I find a easier method this is how I will do it I would be more than Happy to help you out any way I can my cell # is 949 -632-0640 fell free to call Thanks HBLOCAL
 
Thanks for the diy guide it's a huge help! I think it's so much better to have the top tube as the tank instead of that kit tank strapped over it. I saw a new post about using Felt bikes so I will also pass this info on.
Thanks again,
