I have 1967 Triumph T120R. Should I buy new Amals for it or get mine sleeved? How about a new body and slide? Help me decide please.

Get yer amals sleeved, clean out the pilot and flatten the joint faces and they'll work forever and not look like a tutu on a boxer.

if you clean out the pilot jet first and make sure there are no air leaks you might find they do not need sleeving at all....

Must agree with Alex, a well sorted AMAL is a great carb, good performance and economy and a lot less complicated than the Tutu option.

" Should I buy new Amals for it or get mine sleeved?"

Could you hold them a bit closer to the computer so we can see which carbs you have and their condition.

I do not want to start another "AMAL yes - no... why yes - why not" discussion, but... (there's allways a but) smile
I've got my PWK sorted out now. It took some time due to lack of time, but (yes I told you) the bike runs perfectly with it.

I bought new Amals for my lightning a couple of years ago. I have had to address a sticking slide when I changed slides for a leaner mixture. If I had to do it over I would resleeve.

"Like a tutu on a boxer" , very well put sir, I agree completely,
re sleeve would be my preference, be prepared to lean out the slide cutaway though, re sleeving is usually done to a tighter slide clearance than the rattling fit of a stock AMAL.
Stock is at least 3 thou clearance. A friend who is a good machinist resleeved his concs to 1 thou clearance then had to borrow a set of old carbs from me to get the bike running properly until he got new leaner slides .
My own bike still has its original carbs, there like my favourite hammer only had 3 new shafts and one new head since I got it.Pod

Responding to the original question, I think you have to consider the condition of your current carb, the longevity you're seeking, and your budget. The only way to go for long lasting solution IMHO is a installing a carb that has dissimilar slide/body materials. But there are options based on your budget.

If your old carb body is decent, and the brass is in serviceable shape, then I would re-sleeve. Lund does a great job with the rebore, sleeving, and machining the mounting surface for a virtually new fit to the manifold.

But if your carb body is funky and/or your jets are worn anyway, it may make more sense to buy a new AMAL. You'll get like-new performance...for a while. Eventually the slide will wear out again and you'll be faced with sleeving or replacing once more.

So, a new chrome slide ($65USD) on a new AMAL is the way to go for longevity. Kind of spendy, but will avoid costly and maddening tuning hassles in the future.

Sleeving = $80USD ea. plus $30 worth of new jets
New AMAL with chrome slide = $350USD(?)

My 2cents...

Dale

I recently fitted stainless sleeves to a pair of slides,didn't rebore the bodies.These carbs are more than 30 years old and run better than new.
I am running less than the 0.004"clearance, and opened the cutaway slightly.
The main things to get right are needle jets and cleared out pilot jets.

The 930 on my T100 was sleeved over 25,000 MILES ago and is still a treat, as they say. Mind you, I do use an air cleaner and I do change the filter and all those silly things. I think that a well done resleeve job should last longer than a new carb if they are made of the same similar materials that they originally were. Walridge had mine done for me and we also had a 930 done for a Victor, too. My thoughts......Wilf.

I would be interested to hear how you achieved that Pete.

The std AMAL slide is very thin wall and quite delicate structurally. presumably you reduced that further to fix your sleeve ?

Sweating the sleeve to an original slide would appear to be impractical, did you use epoxy ?

I suppose everyone who sleeves slides uses a similar technique.The sleeves I used are about 1/16" thick.The slide wall is about 2mm at the thinnest part,so there is still 0.020"or so when its turned down to fit a sleeve,which is just pressed on,then finish turned or ground.I ground mine.
All turning/grinding is done on a mandrel inserted in the bottom of the slide,and the slide is secured with a 1/8" screw where the needle fits in.

I would agree with Dale, I replaced 2 early 932's on my 1966 Spitfire two weeks ago with new 930's from Ken Jackson. The new 930's come from remanufactured molds and have removable pilot jets. I had a mismash of early 932's and I was chasing a problem in the right carb. In my case, it made more sense to me, to replace both carbs rather than continue with replacing jets and working on the carb bodies. If I had sent them to Lund for resleeving, they could have corrected the problem, however, I felt going with two new 930's was the safest route and only cost a few dollars more. The new carbs are great. On the first test drive I took the bike to 6,200 in first and second very easily, which I couldn't do with the old carbs. Just my 2 cents.

Has anyone had Amals Resleeved by someone in Australia. I need mine done and am having trouble finding someone in Aus who do it. Cheers Coopers
