Title: Amal carb & intake manifold Post by marty62253 on 06/15/06 at 07:26:53 Finally starting to tinker with the 38mm Amal I got from Lancer and: 1- got a velocity stack from Surrey Cycle in England -It looks pretty good AND fits without having to move the battery box. 2- I can't install it because I can't get the 2 screws holding the intake manifold to let go of the engine. I took out the battery box and air box to make some room to work in. I can get a hand impact tool in the space but I can't swing a hammer at it. Any ideas how to get them started?

Title: Re: Amal carb & intake manifold Post by vroom1776 on 06/15/06 at 07:39:49 Get some "PB Blaster" and let it soak for a while.  That should help.  There is a better type of penetrating agent, but I'm not sure which.  Then there's this stuff called "Liquid Wrench."  Spray it on the tip of the screw driver and go to it.  Also, some screw drivers have a hole in the handle.  Stuff another screwdriver through there and turn.  Some also have a nut more or less welded to the base of the shaft.  Apply a metal wrench.  Be careful not to strip it out or you'll be buying a screw extractor kit (a good idea anyway) or welding a metal rod to the head of the screw.

Title: Re: Amal carb & intake manifold Post by Dragon King on 06/15/06 at 07:49:33 just wondering what year bike you have. Also I know that sear's sell some could easy-out as a last resort. you may need to change the main-jet down in size. my Amal came with a 300 main jet. not sure what size I will end up with as it is in the shop know. not sure what carb Lancer is using but he is done to a 230 main jet

Title: Re: Amal carb & intake manifold Post by marty62253 on 06/15/06 at 08:55:28 My Savage is a 2002.  38mm Amal MKII Exhaust is a small Indian can made by supertrapp with 23 or 24  3 inch internal disks. sounds great - but-needs more fuel than i can get from stock carb with stripped jets (don't ask - I got it that way) I,ve soaked it with liquid wrench,wd-40 and other penetrating solutions for several days now - think I'll just get one of those exractors that you can put a wrench on and hope the heads  don't snap off the screws. As for the jetting - I'm a bit of a grump about tinkering - I just want this thing to go so my almost better half can cruise in style...SO.. if you could keep me posted on your jetting results I'd really appreciate it. Which Amal do you have and what exhaust are you running?

Title: Re: Amal carb & intake manifold Post by Dragon King on 06/15/06 at 09:02:59 I have a Jardine Exhaust and can not rember if it the 36 or 38 amal mark

Title: Re: Amal carb & intake manifold Post by HawkEye1967 on 06/15/06 at 21:16:06 Yep I had the same issue to remore the stock carb had a impact driver and all, heads where like butter, just took a rotary drill and cut the heads off the bolts, clean and smooth without wrecking the intake mainfold, then the intake mainfold came off the bolts, and the leftover bolts came out very easily with pliers once there was no pressure on them.  (Just to confirm that the intake manifold is the piece holding the carb to the cylinder, did not know its name.)  May not be the answer of choice, but it worked for me.  as far as I know Lancer is running a 230 jet in a 36 mikuni carb at this time.  but I am open to correction.

Title: Re: Amal carb & intake manifold Post by marty62253 on 06/16/06 at 15:20:07 Thanx all...time was the answer...3 days of squirting liquid wrench whenever I walked by garage and the screws all but jumped out this morning. Replaced them with hardened allen heads for future. It's all together except fuel pours out of fuel line -Amal nipplything is smaller than stock and I only have heavyduty 5/8 fuel line - a hose clamp should let me try tomorrow. Lancer is down to a 230 main jet in a 36mm?---this scares me --I've got a 38mm and the main jet says 320 on it . Where can I get jets for this thing?? Hey Lancer - if you read this, please drop me a line.

Title: Re: Amal carb & intake manifold Post by HawkEye1967 on 06/18/06 at 13:14:05 Chances are the Local Dealer, and or Bike Shop can help you out, just phone around and ask if they have main jets for a amal carb, I have had no issues getting jets for the mikuni carb, at the local bike shop.  Good Luck.

Title: Re: Amal carb & intake manifold Post by lancer on 06/21/06 at 08:09:27 Hi Guys, If you do not have a local source for jets for the amals then go to British Only, www.britishonly.com, they have every single little part for any amal carb made in the past century.   To clarify something that has been mentioned above, the #230 main jet is on a 36mm Mikuni VM carb that has something called a UFO in it..Ultimate Flow Optimizer.  This is a small piece that fits on the bottom of the slide and creates a smooth surface so that the air flow through the carb bore is accelerated and reduces turbulance.  The result is much improved fuel atomization.  The pilot jet, normally a #35, is now down to a #15 and it still has more than enough fuel/air mix.  The UFO mostly affects the low speed range, some in the midrange and  high speed range. I posted some pics and info before I left a couple of weeks back.

Title: Re: Amal carb & intake manifold Post by Dragon King on 06/21/06 at 08:30:30 found this place for jets http://northerneagle.ca/triumph%20Intake&Fuel%202.htm we ordered 230,240,250,260,270 not sure witch one we used yet cause it still in the shop. as soon as I know I'll post for you

Title: Re: Amal carb & intake manifold Post by marty62253 on 06/21/06 at 15:13:32 Thanx Dragon King - While you're at it - see what size pilot jet is in there. Oh yeah - what are you using for air filter??

Title: Re: Amal carb & intake manifold Post by Dragon King on 06/21/06 at 16:55:22 using the air filter cone that lancer sent with the carb  Re: carb « Reply #5 on: May 28th, 2006, 10:34pm »  Quote  lancer Modify   -------------------------------------------------------------------------------- The factory air filter will definitely restrict air flow, I would advise using the aftermarket filter... it will help a good bit with more power and aid in your jetting job.  The main jet needed will depend on the engine, carb, filter, exhaust, and ??.  Go down one size at a time until the bike runs strong at full throttle without bogging down.  Stop at that point on the main jet.   Then check the midrange ... which notch on the needle does it run best in the 1/4 to 3/4 throttle range. Then the pilot jet setting that makes the highest rpm @ idle...should be between 1 & 2 turns out...less than 1 turn out and it needs a larger pilot jet...more than 2 turns out and you need a smaller one.   When tuning a carb, it is all about "throttle position", 1/4 or 1/2 or 3/4 or full throttle, not mph or rpm (except pilot jet). For just getting a few jets to tune with you will do better getting them locally, it will save you shipping costs.   If you are unsure of the jet size just pull them out and look...it is printed on the main and pilot jets.  Sometimes a magnifyer is helpful.   This is a good place to review some tuning stuff.   http://www.mikuni.com/fs-tuning_guide.html

Title: Re: Amal carb & intake manifold Post by marty62253 on 06/22/06 at 05:53:38 THANX AGAIN D-K AIR FLOW SHOULD NOT BE A PROBLEM - I HAVE A K&N IN THE AIR BOX. REMOVED A GOOD AMOUNT OF THE DOOR AND WALLS OF THE BOX AND REPLACED WITH 1/4" METAL SCREENING TO KEEP LEAVES AND OTHER LARGE DEBRIS OUT. I THINK THE MAIN JET IS PRETTY CLOSE (I DON'T HAVE TO SAY WHAT A PAIN IT IS TO GET AT SPARK PLUG WHEN IT'S HOT) AND NEEDLE CIRCUIT PULLS WELL. PILOT IS SET AT 1 1/2 TURNS (FOR FASTEST IDLE SPEED)BUT I GET A TON OF BACKFIRE ON DECEL. WHEN I RUN PILOT 1/2 TURN OUT THERE IS MUCH LESS BACKFIRING. I THINK YOU MAY HAVE PILOT JET SIZING REVERSED. TOO MANY TURNS, GO SMALLER--TOO FEW TURNS GO LARGER. ANY HELP OUT THERE??

Title: Re: Amal carb & intake manifold Post by Dragon King on 06/22/06 at 07:56:35 lancer is the best to help send him an instant mess. also I have a thread a coulpe pages back with the subject carb that may have some usefull info for you ;D good luck and let us know how it turns out. and just so you do not feel alone I got my carb last sept. and there is some other things that I needed to do first like have lancer make a custom throttle cable and then never really got started on it until april. then took it to a shop about 30 miles away and they had it for two months and did nothing with it. then was going to try it myself and went to the stealership to order some jets and after taking to the mech. that I know was even more confused so I let him take it and he said he would keep the cost down for me. the funny thing is that the amal goes on triumph and the stealership sells triumph along with suzuki but could not get any jets for the carb ;D

Title: Re: Amal carb & intake manifold Post by marty62253 on 06/22/06 at 08:07:00 Triumph stealership with no Amal jets - Go Figure

Title: Re: Amal carb & intake manifold Post by HawkEye1967 on 06/22/06 at 18:33:50 Have a 36mm Mikuni from Lancer with a cone air filter, it came with a 310 jet installed, down to a 240 jet at this time, but have purchased the 220 jet to try, I think that one will be about perfect, on a different note I have noticed that with the cone airfilter, the bike (motor) is louder/ sounds different/Better. and this is with the stock muffler on.  I hear the motor thru the airfilter over the mufler, sounds kinda like a bratttt sound instead of the pop pop of the muffler, I LIKE IT ;D

Title: Re: Amal carb & intake manifold Post by HawkEye1967 on 06/22/06 at 21:40:50 have changed the main jet to 220, now the low end start of throttle is bogging down, so does this mean too lean or that I need to change the pilot jet to a smaller one as it is now getting to much fuel at 1/8 throttle ???

Title: Re: Amal carb & intake manifold Post by Dragon King on 06/23/06 at 15:08:45 the piolt jet is a 25 it is what came with the carb. should have all the details by next wed. but what we are starting with is a 230 main and the neddle in the middle postion

Title: Re: Amal carb & intake manifold Post by HawkEye1967 on 06/25/06 at 12:55:09 okay update on my carb,  running with the 220 still, but at the same time I had tried to change the float level as mine is too high ( I know only one change at a time)  I went back in and change the bend of the tab back to it's original spot, bike runs good overall, might try a 230 jet, but the float level is still too high.  I beleive that to change the float level I need to bend up the tab on the lever that contacts the pilot jet (is this right ???)  but when I did that I lost my low end, so then do I need to bend that tab and change the pilot at the same time?  not very knowledgeable about this, but I am willing to learn, Help Please!

Title: Re: Amal carb & intake manifold Post by Dragon King on 06/25/06 at 15:35:08 I do not know alot on carbs that is why I'am having  the stealership do it. Lancer is carb expert so shot him an instant message and he will be glad to help. Lancer has helped me alot ;D
