Another "My bikes got a problem" Thread

[EJK]

you are hereby officially forbidden from buying more than a battery, a tube of araldyte, and a 2nd hand carby for that FXR.

i don't wanna see you go spending a grand on parts and labour when squiggles could give you a carb for 50 bucks, you can buy a suitable tube of epoxy glue for $10, and a new battery for $60

that's $120 my way, vs $1200 the colemans way, and either way it still won't be done till you get here to pick up the bike!

(and just today i read a thread where a guy sent a bike into colemans with a list of symptoms including a boiling battery, got charged $120 to be told it was fine, and then at home used a multimeter to find the reg/rec was rooted in about 5 minutes)

Who said I'm going to buy all the parts from colemans?

Geez, I just found out the price for an aftermarket filter foam bit...

I have two weeks or so left... Now, every hour of bike not working is a pain.

P.S. Steve doesn't have a spare GN carb.
P.P.S Any suggestions on carb? Can't find any on Trademe (wrecks).

So need to swap the carbies to see if it is the carbie, if it is the carbie then it what Ixion sez! How hard can that be? Tch, youn'uns these days ... always thinking "its fecked" like chicken little!

Its funny to read how we are so much fecked off by this admission of defeat, yet we are all prepared to help the little bike back onto the road!

EJ, do the right things like you know you should ... sitting on your hands wringing them is pointless when you have so many willing to help you ... grow a backbone and be a proper biker!

I'm working on it!

I've never done anything like this before.

Right now I don't know where to get a carb from. Plus I barely have time to do a search.

He means swap the carb with the working FXR carb Motorbyclist has, just to see if it'll run properly. If so, then it's confirmed your existing carb is fecked. Probably not necessary to buy a whole new carb; the other problem with going to a GN250 carb or CB250RS carb or whatever is that you will almost certainly need to dial it in a bit -- swap jets, move needle, fuck around. Plus, is it going to match straight to the airbox?

I know you're impatient, but let's try and sort the existing carb first to save hassle in the long run.

[motorbyclist]

what happened to that DR250 stephen was parting off?

we'll use my one as a test to be 100% sure it's the carby only causing a problem, but we'll want to try a 250 one before buying incase it runs like a dog

ready when you are

[EJK]

Yeah guess my patience seems to seeing its end since I'm under stress about the time.

Well, when is good to try? I'm free whole day tomorrow.

Hey Andrew, can we try that? Using your Carb just to test its the right problem?

Thanks.

Sigh, time to contact Justin again for a pick up...

The DR i'm parting is from 94, and no idea of the condition of that carb anyway

I only have one really good gn carb (in pieces), the others have pinholes in the diaphragms... Shoulda bought that $60 one off tardme, it was a minter

Do the carb swap with mb's fxr, piss easy and will reveal all.

[motorbyclist]

ok, it is definitely the carby. swapped them around and the bike ran sweet.


currently looking for a new carby to fit the bike rather than the diaphragm. pushed the slide up and it doesn't return anyway. we see a GN250 will fit fine.


approx dimensions: Inlet 45mm OD 40mm ID Outlet 37mm OD 28mm ID body roughly 87mm long

wish EJ had bought that $60 GN one on thursday, would be here by now...

[Buddha#81:Me]

Widen your search.....a early '80's 250cc XR, XL, carb will fit. Thats what i've got on mine and I can give you details of jetting etc.......

A GN250 carb is the ultimate they fit and jetting is correct standard.

[EJK]

What a coincidence... Searched up on Trademe "XR 250" and someone was 'coincidentally' selling XR parts...

and 'coincidentally', the sellers ID is Squiggles.

PM sent

[motorbyclist]

how'd you fit that XR carb? don't they have the bolt on style manifold?

[Buddha#81:Me]

nope same as FXR, fits straight on! I'll go and take a photo, stay tuned...............

[Buddha#81:Me]

Here ya go......Sketchy Racer did the conversion so I don't know much about it but it produces slightly better low down power over GN250 carbed FXR's

[EJK]

Ah I see... Thanks very much for the pics

[xwhatsit]

Same as a CB250RS carb. I have three, but they're all in bits. The advantage of the CB250RS carb over that XL250S carb is that it has an accelerator pumper. I can't see that on yours -- but it's got the hole for it above the float bowl. Very strange.

Anyway, like I said, I've got enough bits to make three CB250RS carbs, but they're all in pieces. What jetting are you running, Buddha?

EJ -- what year is the XR250 on Tardme? They changed markedly after about 1982 (which is what we need -- pre 1982), went to a dual carb set-up for a while, then the engines got more powerful and higher compression and went to CV carbs and all kinds of silly things.

[EJK]

Its a 1987 model I believe...

However, would a Honda Carb work on a Suzuki bike?

That'll be too new. It'll either be twin carb, or CV -- not the earlier PD70A/PD70C style round-slides.

No reason why not, lol! You know what's scary? I've got a Suzuki headlight on my bike -- and Tommaselli clip-ons -- and I just got a Yamaha headlight in the post from Japan I'm going to bolt up. How's that!

At any rate, neither carb is Honda or Suzuki. The Honda carb is a Keihin, and the FXR will either be Keihin or Mikuni.
