Custom 18mm Tomos Intake - PICS

King Drunky JCams /

Check it.

My friend Jamie and I finished up a new custom 18mm Mikuni carb intake for a friend's Tomos. Wanted to share.

Here is the setup...

1985 Tomos Golden Bullet

A35 CDI engine

70cc Alukit

Stock intake - dremeled

15.15 Dellorto SHA

2-Piece Bi-Turbo (have a NIB Homoet 4p to try)

I ran for a few miles a stock tomos intake that someone had dremeled out a bit...

Since the kit is new, I can't run it too hard, but I can tell the small intake is affecting performance in a negative way...

It just felt like the bike could not take a deep breath, so after looking and finding ZERO performance tomos intakes, we improvised.

We basically have replicated the intake and carb setup on my Pinto with the Gila kit to run my new favorite, 18mm Mikuni carb.

1" steel tubing purchased and bent at home depot fits perfectly inside a 18mm Mikuni with the spacer removed...

I bought the tubing, walked to the conduit section, grabbed a bender, bent the tubing, and walked out.

Took some thick ass flat stock Jamie had at his shop... cut the 1" tubing where we wanted it.

Tacked it in place on the bike, then removed and finished the weld. Leak check... None. So, a little sanding/grinding and some BBQ rattle-can paint... done.

Here are some pics...

Can't wait to run it tomorrow.

Should freakin' rip.

SICK!!! very clean job!!!!

Re: Custom 18mm Tomos Intake - PICS

nice fab job dude.

Looks great. That tomos should rip.

Re: Custom 18mm Tomos Intake - PICS

nice job. make these, and sell them.

Re: Custom 18mm Tomos Intake - PICS

What kind of welder did you use on that? MIG?

Re: Custom 18mm Tomos Intake - PICS

Jon-O - that just might happen.

I'll most likely intake and matching 18mm Mikuni carb setups.

Pavel - cheapy wire-fed MIG from harbor freight.

Re: Custom 18mm Tomos Intake - PICS

that is radtown. what bike did you get that 18mm mikuni off of ? an old yz of some sort ?

Re: Custom 18mm Tomos Intake - PICS

yeah dude. i think you'll make money off it. you might also want to think about making phgb setups as well. those are kind of the preferred moped carb, for some reason.

you getting ahold of some cheap mikunis or something?

Re: Custom 18mm Tomos Intake - PICS

Damn thats like the EXACT set up I run accept I run 15 arreche. I went through the same thing. Someone needs to build and sell tomos phbg 19 mm intakes. I would do it but I have no access to a welder. Look good. Lemme know what it does for you.

Re: Custom 18mm Tomos Intake - PICS

King Drunky JCams /

Yep, I get wholesale mikuni stuff.

The 18 mikuni's are purchased new... no old carbs here.

As for the PHBG, I imagine a 18 or 19 would work just fine on this intake... but a Mikuni 18 fits flawlessly.

I have a 18mm PHBG on my Minarelli.

Love it.

But, I love my 18mm Mikuni more!

Re: Custom 18mm Tomos Intake - PICS

I know I'd buy one straight up.

Re: Custom 18mm Tomos Intake - PICS

anyone know if 24mm mikunis also have the same intake size?

Re: Custom 18mm Tomos Intake - PICS

Yeah, I have that same carbs non union indian version in 16mm's on my express. Definitely like it mega.

Harold, unfortunately, I sold my 24mm Mikuni Flat Slide.

Never measured the dimensions.

I do know the 25.xxxmm is equal to 1".

I wanna say it's 30mm (Jamie says 31mm) O.D. on a 24mm Mikuni Flat Slide...

Jamie says, 1.25" steel tubing should work... the 24mm Mikuni FS is also not a clamp on style carb... I used a radiator hose cut down to fit with hose clamps to connect the intake to the carb...

Re: Custom 18mm Tomos Intake - PICS

jesus christ dude learn to weld!!!! or how to use a grinder

Re: Custom 18mm Tomos Intake - PICS

^those flux core mig welders lay down shitty looking welds. its fine though.

Re: Custom 18mm Tomos Intake - PICS

^ um no they dont if you use the right purge you wont have any splatter plus if he spread it out evenly then the slag would chip right off... i know im a welder...

Re: Custom 18mm Tomos Intake - PICS

No reeds huh? How big an intake can you put on a flat reed setup?

Re: Custom 18mm Tomos Intake - PICS

oh my bad. ive never seen a good looking flux core weld, thats all im saying. most people who use flux core dont really give enough of a shit to care about how the weld looks.

Re: Custom 18mm Tomos Intake - PICS

i agree with jon-o. i have a cheap 200$ flux core welder and i can never get more than an inch or two at best of good looking bead.

it just doesnt come out evenly dude. maybe brand new out of the box but after you get some miles on it it works like crap. my method is overweld and grind off. my neighbors fucking hate me.

Re: Custom 18mm Tomos Intake - PICS

i hate you! <3

Tommy, I don't give a fuck about your expert opinion OR welding.

Not even a little.

The welds work, and don't break, so I run 'em.

Guts, I'm running reeds...

Re: Custom 18mm Tomos Intake - PICS

and if you think thats a shitty looking weld, you should see some of MY work, lol. i broke a chinese scooter in half jumping it and welded it back together. looks like a giant pile of shit.

Re: Custom 18mm Tomos Intake - PICS

shit talkin' hippy /

"tommy hairspray", _expert_ welder ... expert dingus.

Re: Custom 18mm Tomos Intake - PICS

shit talkin' hippy /

J-Cams, if it holds and doesn't leak, it's a good weld to me dogg!

Re: Custom 18mm Tomos Intake - PICS

King Drunky JCams /

Damn right Hippy.

FYI the bike fuckin rips.

Idles great, super low end, and felt real good.

Gotta try that Homet 4p ASAP!

Gonna post pics in a while...

Stay tuned...

Re: Custom 18mm Tomos Intake - PICS

NO BITCHASSNESS!

dude get a 4petal reed setup.

then you are faced with a whole new problem.

i need to make an intake for my 21 oko and 4 petal..

im thinking of casting a need reed spacer and then welding an intake together.

is it important to have a square intake go to the 4 petal reeds? or can i run an intake like the one this forum is about?

Re: Custom 18mm Tomos Intake - PICS

King Drunky JCams /

Dude, I just said it rips.

No need for any reed upgrade.

I need no more "whole new problems"

Re: Custom 18mm Tomos Intake - PICS

true, but your not getting all you cold out of the carb with a 2 petal flat reed setup.

Re: Custom 18mm Tomos Intake - PICS

I fucking love it I will show this post to my brother. He is having this problem right now.
