The good the bad the underneath.

I told a member on this forum that i would put up a thread on the custom under slung exhaust.
First of i happen to luck up on one of the exhaust from a mini chopper.I cut it to the lenght i needed.Then went to the hardware store to get another piece of pipe to finish.The section of pipe leading up to the exhaust can was from the stock header.With a little heat i was able to bend it lose to what i needed.In all honesty i can't weld for SH*T.LOL So but the next one i do i'll make it all pretty.But this set up was designed around a 110cc motor.I didn't factor in putting a bigger motor.Which meant the whole system would have to be slid forward.That i decided to use hose clamps instead of welding again.

I used the support legs off of one of those stands that holds the sheet music.I forgot what the called them(LOLOLOL)presto exhaust hanger.

[swheels]

I almost forgot heres some pics and links to some exhausts that can be used.Or you can buy one already to go.

ya i like that S
its not real pretty but i bet it works good
i hate that big J in my pipe and its SO close to my head and plug area
scuff it up and hit it with some high temp paint
your bike looks like your a good rider, pushing the limits, max performance
hows that lifan so far? you gettin better lap times at your 'spot' with it?
are you gonna sheet thelog lol lol

[swheels]

It definitely flows better than the j headers.I noticed the difference instantly when i had the 110cc motor on the bike.
Lifan seems to be working better for now.I plan on hitting up the test facility this weekend.Then see how much this motor can take.With the way it's running now.Oh yeah i'd definitely handle thelog.....The funny thing is i'm running the cam from my 110cc motor.

[Blitz$M.Inc.$]

dang yer runnin a honda 50 style in a lifan?
i didnt know they were compatable, is yours a big valve head?
i bought a lifan bv head from holeshot
turns out its really a zongshen head with the same big valves but the cam is completly different
i just sent the wrong one i ordered back to AHP, those guys are nice
i asked hole if it was a lifan head too machinegun holeshot

lol besides the welds(I couldn`t do any better so what am I talking about?lol)
thats a sweet set up.Will it fit in the x-18 fairings though? How would I go about making that style exhaust so I could put the x-18 fairings on over it? What did you use for the header part(bolted to the cylinder)?Lastley what yoshi can is that,like is it just a universal?

[The Nutty Professor]

To get around a lot of the welding it might be easier to use a tube bender. Using a long enough piece of tubing and a bender you can lay the pipe in a bend as you go. Using a flex ruler or a thick gauge copper wire would help a lot. Using the ruler/wire you bend it until you have the right shape. Then lay it up to your pipe and start bending. Spending time getting the template right and practicing your bending will make the job a lot easier and the finished header look a lot better. Cutting your flange for the exhaust port takes a bandsaw and time or you can cut one off a donor header. The first and last pictures are Harbour Freight and the two in the middle are of a DIY net plan bender.

[Blitz$M.Inc.$]

hey swanni, the 18 fairings will fit after they melt in the proper holes!
his header is from a mini chopper

[swheels]

What did you use for the header part(bolted to the cylinder)?Lastley what yoshi can is that,like is it just a universal? Your x18 fairings will fit over it with no problems.I have x7 fairings which are waaaaaay narrow in comparison to the x18.The header i use will bolt right up no mods needed.The yoshimura slip on can was from a 1:1 bike compliments of the nuttyP.The yoshi can was about 15in long.I had to cut it down so i cut it to 8 1/2in.Then i used the end cap from the stock exhaust as the inlet on the yoshi.Then welded up a piece of the stock pipe to it.So i can take it off without haveing to remove the whole system.
Well just as a quick test i took off the yoshi can then put back on my thermos can.With the yoshi i had motor better lowend end the motor topped out quicker.When i put the thermos on it didn't feel as strong on the lowend but mid was ok the top end was sick.The rpm's just kept going and so did the motor.Plus the motor ran cooler ofcourse.:cool:thumbsup2

[Blitz$M.Inc.$]

well it is a high performance thermos!

[swheels]

Heck yeah.I paid a whole 12.00 bucs for it.Its walmarts best thermos multi function high output.motorbike

lol which thermos was it? did you weld it to the factory x-18 exhaust?

[swheels]

lol which thermos was it? did you weld it to the factory x-18 exhaust?It's a stainless steel one and you go to the houseware section OOPs i mean the high performance mid/superbike section(Yeah thats it)They have them in different sizes.i didn't weld it just make the necessary holes then bolts right up.I placed the bolts through the inside of the thermos then put the nuts on the back.There is a inner and a outer part to the thermos.I cut the bottom out to get to the inner bottom.Ofcourse theres no packing in it but i made the exhaust hole 2mm smaller than the stock pipe.To give it some kind of back pressure.

[redryderaus]

I love it! A bit of bush engineering. Great idea to use the thermos for a muffler can.

Reading this reminded me of the muffler I made for my VFR400 racer (now that was a wild little bike to ride!). I'll post up pics of the muffler later. I'm thinking of modifying it for the X1.25 . It wouldn't be hard shorten it but it might be a bit big diameter-wise to look right . And the bore is about perfect. I want to do an "under" style exhaust both for looks and also I don't think I'll have room inside the X1.25 frame for an "over" style. banana

Swheels in his workshop. Mrs Swheels walks in to find him cutting away with a hacksaw.

"Is that my good thermos??" demands Mrs Swheels.

"But darling, it's the perfect size for the muffler I need!" replies Swheels.

i had that happen when i was searching for a cap for a custom gas cap
i found the right one on a bottle of cleaner...

[swanni06]

I just wish I could build the stock 11occ motor and it have lots of pep without spending a fortune...ANYWAY sorry for high jacking your thread S,great how to. rock

[x19er]

well it is a high performance thermos!
Turbo Java dunno

[swanni06]

What do you think about this exhaust? its for a Honda ct110. same motor right?

[The Nutty Professor]

Yeah same motor. Where did you find it? It looks like a custom pipe. The springs give that away. I have yet to see an exhaust for one of these that uses springs (I think). That more a race bike practice. One thing though that pipe is going to cost a whole truck load of thermo's.hangloose

I found it here:http://dratv.com/12po10himato.html you might wanna go check out that site,its rep parts and some hi-po parts for the all the honda mini's. I bought stuff from them when I restored my 1969 honda trail 90 or ct90

[swanni06]

here is the link I wanted to post instead of the one above

do you think this pipe would fit?http://cgi.ebay.ca/MUFFLER-PIPE-HONDA-XR50-CRF50-XR-CRF-50-125CC-PIT-BIKES_W0QQitemZ110171847810QQihZ001QQcategoryZ3559 6QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

The only problem I would see is heat. If it was a carbon pipe I would say no problem, but a high pipe would be very close to the ham hocksmachinegun2.

Blitz,

What cam did you order? I coulda swore that the supplier told me these are lifan BVH's. Also, the TB cam for the lifan BVH with the new cam sprocket work just fine for me.

[Blitz$M.Inc.$]

i ordered it from ahp and they are having web problems but here is the same cam that i ordered
http://tboltusa.com/store/product_info.php?cPath=51_52&products_id=360
you can see the difference
i had to take pics and send lots of emails to get it right and they finally did

Blitz,

Thats odd, i have not run into that issue yet maby the supplier just goofed and sent me a zong head by mistake. Anways, if ya dont mind can u let me know what the part number for the cam that head uses is just for future reference so i dont run into this problem.

[Blitz$M.Inc.$]

um, i dont know actually
its a race cam for the big valve zong head
the difference is clear
the one that i got is missing the notched oneway lobe
he said the performance cams do away with that
its real noisy running and i think its the aggressiveness of the cam
it runs like a beast

..I watch Orange County Choppers! LOL.. sorry...hangloose

[chewbaca]

hey guys.
ill be working on a new pipe. i have a real tubing bender. 1",1.25",1.5",1.75" dies. it makes a beautiful bend. as nice as a mandrel bender as long as the tubing isnt too thin.
would a good pipe for racing be best as starting with one inch and going up to one and a quarter? should flow faster. or just one and a quarter all the way?
if you have a little patience i should have some material in a coulple weeks.

[The Nutty Professor]

Hey "S" you modified your pipe again why don't you show the masses. Not putting you on the spot or anything. But guys that pipe looks sweet.

A major regret about what I didn't do at Elgin is that I didn't take a lot of detailed photo's of "S" and Dub's bikes. Getting ideas is everything.

[Blitz$M.Inc.$]

sweet although the first thing i thought was on no, no more thermos!
looks good tho, i was working on my underslung when i had to move
i want that can that gusrod has

[The Nutty Professor]

The photo's don't do the pipe justice. It's very well put together and smooth.

[swheels]

You know I'm gonna keep sayin' it..............
:phat:Sick Bike! :phat:Thanks shooter.But im affraid in this case the bike looks better in the pics than in person now.LOL I can truly say the fairings are hanging on with zip ties.LOL

sweet although the first thing i thought was on no, no more thermos!
looks good tho, i was working on my underslung when i had to move
i want that can that gusrod has Come man that thermos was bomb! what other midbike you know of can race and heat up some soup at the sametime.thumbsup2 LOLOLOLOL

[relaxednoma]

thats bad ass S

[X-18]

Nice bike Swheels. I like the under slung and the way it flows with the rest of the bike. Is that a X18 frame with X7 fairings? I'm going with the naked look and just received the X7 rear, seat, and tank. I haven't really looked at how they fit on my X18 frame since I've been a little under the weather.

And as many have said :phat:

[dna316]

wow S, everytime i see that bike i need a wetnap. lol nice nice nice job
