Okay Spinner. We need you to elaborate. "Upside down"? - Upside down on a horizontal plane I assume? Or do you mean rotated back to front? How can it be possible to rotate the spring 180 degrees back once you have engaged the bolt through into the S/Amount - impossible, (maybe it's a syntax/description issue). Three lads here have just battled for about an hour and a half, we finally got it done but. And we're no newbies. I've done a hundred tensioners, and I know they can be nasties, but this one on our GG 280TXT Pro is a doozie! How do you mean upside down? Any chance of a diagram or picture?

Here's pics of the Re-co kit from the UK (that has the longer 58mm needle).

Thanks guys. Interesting tlrider "I ordered a 22mm carb listed as fitting the TL125, physically it was too large to fit the bike" -Have to assume that you got wrong info from the seller telling you it was for the TL125. Yup, the type with the Springclip floatbowl is correct for a 'K' as you say, and until someone says they know different I'm going to say that this carb has a needle that is approx 43mm long. Does anyone have an 'S' carb handy that they could measure the length of the needle? (If it's 58mm then that pretty well solves the problem). Key to it is identifying what carb the Cotton kit (with the 58mm long needle) is for. (Helpful YEP tlrider, but not solved yet!)

Right, so... what I need to find out now is if the needle out of an SL125 Is 43mm long or 58mm long. Anyone got a carb handy they could measure the needle length?

No, mine has '20' cast (not stamped) in the top plate near the throttle cable entrance. I wouldn't have thought this would have any relation to the choke size though would you? If as you say they all use the same basic 22mm Keihin, the Cotton reco kit must be wrong because the Cotton slide needle is 15mm longer than the original one. I'm sure Honda would have used the same carb for other bike models, perhaps with different jetting, maybe that's another line of enquiry - as you say you've used a needle off an SL125.

Help me solve this little mystery. I bought a new Carb Reco kit from IOCON LTD UK (it's a Cotton branded part No. 251353805147) -advertised (ebay) as correct for a: TL125E (England) '73-75. On receiving it I've foundthat it's for a different carb to my (Oz) '74 TL125E K1 model, for example the throttle needle length on my carb is approx 43mm long, but the one in the Cotton kit is approx 58mm long. My carb is the original, -correct for the year and Oz delivery. I think the later 'S' Model may have had a different carb, certainly different jetting. I'm wondering if UK models had different carbs to Oz models in '74. My throttle needle and needle jet are worn, so I need replacements but need to sort out this mystery so I can ID the correct replacements. Anyone shed any light on this? Jools
