Title: Kuwahara E.T replica build, With Pics...
Post by: GREMLIN on May 08, 2008, 01:57 PM
Hey lads,
I picked this up off the evil-Bay yesterday  :). I think i got it at a fair price. I don't know yet if it was off a Rad member  ???
A lad called Jason - ebay i.d Hollowayfield... ?

Scanning through the sites old threads i think i've nailed it down to once belonging to Jimwise68 (as his Elliot replica), and then Tefore ?
Maybe even more Rad members  :D

Any help with this lads?  ;)  Also what is the final word on model etc?  Chrome Kz2.5, Kyz etc ?

(http://www.radbmx.co.uk/archive/albums/f376/greml1n/06b2_3.jpg)

I'm not going to follow to the word the spec sheet build for an E.t. I probably will source a set of Tange Trx forks and have them painted and then decalled up to fit onto it. But the rest will be close enough 'til as and when i can find the correct parts.

I already have a bottom bracket, sugino 1pc, sugino spider, Dia compe 890 brake set in either black or highly polished, Dia compe levers, Suntour post clamp, plus these bits that are in with the auction...

So any thoughts lads? Advice etc?    Grem'  :daumenhoch:

I believe it's a Tange Hot Heart F&F with a drilled out gusset,  judging by the forks.

Looks pukka though!

It's always a possibility i guess. I'll have to check the dimensions when it arrives...  :)
But if it is as i think Jimwise68 and Tefore's old frame and fork set i'd say it's 99.9% positive to be a Kuwahara model.  G.  :daumenhoch:

Finally traced the serial number down on the frame set. It was Tefore's at one time  :daumenhoch:
The serial matches, and the b.b to top of seat-post tube is 10" so it is a Kuwi and not a drilled out Hot Heart. Which would be 12".  ;)
I did actually think the gusset hole was too small to be a drilled heart... So all's good  :daumenhoch:

Thanx Paul m8.  I'll get it built up soon enough and may bring it down once i'm back from my hol's  ;)   G.

im not 100% about this but i think jim went round a members house recently and the bloke ad his kuwi    so i dont think thats his one  your best of asking him
Title: Re: Has this Kuwi been around the block a few times...
Post by: GREMLIN on May 08, 2008, 03:59 PM
I will ask him as it'll be nice to get the history behind whatever it is.  The serial numbers match exactly tho  :)
Plus looking at the pics of Jim's frame set and the eBay pics they look identical.
Even down to the extended scratch on the rear drop.   G  :daumenhoch:

It was a KYZ originally, apparently they called them the "chrome" ET. It is not a drilled out Hot Heart.

Here is is as I got it:
(http://www.radbmx.co.uk/archive/albums/j135/jimwise68/DSC02195.jpg)


I won if off of Ebay and it came all the way from the other side of Aberdeen. Not from a Rad member.

I got it sprayed in the ET colours and made it into an Elliot replica.

The guy you bought it from lives about 20 mins from me and he bought my Redline from me and when i dropped it round there he showed me his collection of bikes. One of which was my old Elliot Kuwahara. The guy is a member on here but can't remember his user name.

I have the missing ET decals if you want them.

Excellent, thanx Jim.  :daumenhoch:
It's great to have some history behind my new build.
What was wrong with the original chrome then m8?  It looks sweet in the pic  :smitten:   G.  :daumenhoch:

Chrome wasn't that bad, but wanted to do an ET.  :daumenhoch:

Shortly after i found out about the fork difference, I researched on Jamies kuwahara sight and found out about the "chrome" ET monikor.

what's this 10" 12" rubbish. i have both frames here and there is no dimensional difference at all.  ones a brick(heavy), but that's the ET.
where oh where did you here the 10" 12" story. We are gonna need the mythbusters before long :D next thing will be ' if you hold the hotheart gusset up to your ear, you can here the sea but the ET sounds like mating squirrels'

Post by: kuwahero on May 08, 2008, 10:22 PM
this was posted on one of the US forums a while ago. Source was supposed to have something to do with Kuwahara BITD. Apparently, the ET frame is lower than that of the Tange Hot Heart. from the top of the seat tube to the bottom of the bottom bracket on an ET is 10 inches and the same measurement on a Hot Heart is 12 inches.

size matters you know  :LolLolLolLol:

I have a genuine ET and it measures 10 inches. I believe someone confirmed the Hot Heart size when Electro808 was having issues with the frame he bought a few months back.

i reckon there are some wonky tape measures. or maybe it was one of those moody hot hearts.
reet, if you have either bike, get you tape measure out and lets find out if there are any wierd different size bikes about.

That's a good idea  :). 
So you have both frame sets then J.t ?
Obviously i'm only going by what i've seen on this and other sites which have bought the differences up.

If i was unsure about the frame set i'd have done a few checks...

1. B.b to top of seat-post tube (if a size difference is a marker).
2. Weight (e.t steel etc).
3. Welds.
4. Gusset hole size.
5. Serial number (position etc).

i've had 5 hothearts, got one left, 2 sold on here, 2 given away in holland. got only one genuine ET. serial is the same, rear triangle on the ET is high ten not cro-mo, all my hothearts were full cro-mo. hole dia. is 22mm, ones a heart or if it's bigger than 22mm then is moody, if it's cro mo then it's not an ET and maybe a kuwi kz whatnot. (kyz, can't remember or be assed to look for it) but as for different sizes? WTF they were never different from each other. Everybody measur your shit and lets find out for sure.

hi all

Just measured my Hot heart and its 10'' exactly and the heart on the gusset measure's 20mm from the furthest points, cant remember what should be what, just letting you know. i will look on the thread and see what is what.

Cheers steve :daumenhoch:
Title: Re: Kuwahara E.T replica build...
Post by: steve Beech TA on May 09, 2008, 10:22 AM

Just cut out a 21 mm circle and it just covers the heart so if a HH was made into a ET if done well would measure 21-22mm, hope this helps :daumenhoch:

Well that stuffs that theory  :LolLolLolLol:

My ET measures 10inches also

Post by: GREMLIN on May 09, 2008, 11:35 AM
Yup  :D

It's not too much of an issue really anyhow, with mine being a Kuwi'. Nice to lay another myth to rest tho.  :knuppel2:

Great thread i finally sort of feel like i have an answer to a question i needed answering (there's no answer  :idiot2: it seems). I got an e.t Kuwi of ebay US a few months ago and ended up feeling a bit of a pest trying to get an answer as to it's authenticity.
I found the thread not so long ago about the guy sold what he beleaved to be one that was'nt. I pm'd kuwahero (cheers mate for getting back) who quoted the story about the geometry difference he had seen on another site. The thing that confused me, not being up on all the correct terminology was bottom of the bb. If your looking at the serial the bottom is where the seat tube joins the  shell but if the frame is stood up the bottom is where the serial is.
So feeling a little confused and thinking it's just probably me been stupid i found the thread from the guy on OS bMX ( who owned both frames) and pm'd him. I felt my question couldn't have been read properly because the answer didn't really answer my question. I made my apologis and pm'd him again, he attempted to answer my question but ended up talking about both frames in the same sentence. I did'nt know which one he was talking about. I pm'd the guy again with this picture of mine fresh back from the painters and i put these measurements on so as no cofusion could take place but he must have just thought i was a thick  :uglystupid2: and never got back. I thought the picture asks all without confusion check it out.
(http://www.radbmx.co.uk/archive/albums/ff25/glynnyboy/KUWAHARAETmeasurements.jpg)

The only thing i feel happy with is the frame number break down  of it been a july 82 model in time for the october release of the film and the christmas market. Also if it is another model it must have been done an awful long time ago the paint was well old,( A couple of cm's above the serial it also has 106 stamped in , I assumed this must be some sort of zip code an owner had put in after purchase because the same number is stamped in underneath the tange stamp on the trx forks). If the guy is also a member on here no disrespect intended it just he didn't get back after i posted the photo.

Just to mess things up for you even more if you measure a KYZ Frame the same as that picture the measurements are 13" and 11" well just over 13 and just over 11 actually.

Post by: Glynnyboy on May 09, 2008, 05:47 PM
 :shocked: ??? that does throw  :10_2_12: a little bit. So if gremlin's frame was jimwise68 at sometime does that mean that it was a drilled out hot heart that had been chromed or a chrome E.T.
I think it say's over on jamies that some people confused the kyz as a chrome et but it's not. I read somewhere that after the popularity of the film died out some of the et frames were surplus and redone (maybe paint, maybe chrome) differently and sold on. I read somewhere the hot heart didn't come out til 83'. Confused!!! Just a bit.....
Question, were the same forks put on the kyz and the hotheart?
Title: Re: Kuwahara E.T replica build...
Post by: bodamus on May 09, 2008, 06:06 PM
The Forks on Gremlins are the correct Forks for a KYZ don't know about Hotheart Forks.
The hole in the Gussett for a KYZ is always the large type and I think all genuine KYZ's are 1982.

The reason for changing the size of the hole to a smaller one was it was less likely to crack. All early KZ-1's have the large hole in the gusset and all KZ-2's have a small hole in the gussett.

KYZ's have the Large hole gussett because they are older Frames all 1982.

The frame set is supposed to be sent out to me as of today. So when it arrives during next week i'll have the chance to give it a good going over and compare it's dimensions etc.  :)
I'm looking forward to it  >:D   G.  :daumenhoch:

I've seen only 3 GENUINE E.T's EVER and many replicas whether KYZ or Hot heart

Yes Mr J.T Townshend has both and like he says measurement and geometry wise same

A Hot heart can be drilled to be exactly 22mm without doubt

Serials on ET's must start T2

Hot heart forks are the same as KYZ

and basically Only the GENUINE E.T's I've seen have ALL had the correct forks

and not TRX  and other Tange like 99% of the ET wannabees you se on here and the Bay

ALL early Kuwi's were made in the Tange factory and stamped with the same T till the K stamped laserlites ( Bodamus will correct me if I'm wrong  ;) )


Gremlin yours is a Kuwi but not originally an E.T ( no big deal , if you knew anyway )

And like has been said before also all the GENUINE E.T's aren't like Elliots in the film

because his was a KZ1
I even bet the guy's out of Kasabian isn't a KZ1, ( Div with too much money )

If you're going to buy something
FIRST DO YOUR HOMEWORK BEFORE HANDING YOUR MONEY OVER

This subject comes up all the time

If people really want a GENUINE ET then get your wad out and buy J.T racings one


Better still buy a decent BMX

Having said that I've got one  :-[
 ;D

hunterdubber what is the differance between original e.t. kuwahara cro-mo forks and tange trx's from the piccy's on jamie's they look the same?
As you said the frames were made in the tange factory hence the serial starting with a t. What were the forks stamped with, if they were made in the tange factory were they stamped tange?
Also i think this comes up time and time again for one reason, as we know there are an awfull lot of e.t wannabe's out there and in order for peole to do there homework the questions have to be raised.

I'll answer that one while I'm looking, TRX forks have a oval tubing , ET forks have round tubing but both have the same shaped drop outs.

Does the E.T have the same forks as the round tubed laserlite Kz4 Then?

no. as 84 laserlite forks have a ridge and K stamp on the dropouts and face forward like below. they have the same style fork that were found on the KZ1's
