Help!! I'm having real trouble with my recently rebuilt 1982 - 350. Bascially i cannot get the carbs set up right initially. Does anyone know what rough settings i should begin with? ie air screw turns, idle screw turns. I have a copy of Arthur Farrows carb balancing guide and it works ok up till the air screw section, coz when i screw them in or out, to be honest it makes no difference.
Can anyone help? Cheers.

Setting up carbs

Have you checked for airleaks, check the rubber intake manifolds from carb to head and from airfilter to carb for splits. Also remove idle and mixture screws and check for fitment of o-rings, my carbs did not have them nor did my spare set so I ordered some up and found the carb was more responsive. It would also be useful to know what your jet sizes are and the emulsifier tube number. Check also the circlip position on your needle. Have you checked your plug colour, as this gives a rough indication of mixture.

Hi Robin,
I've checked for air leaks and all rubbers etc are in good condition, i have rebuilt the carbs before putting them back on and all the jets where standard for the 82 model. However i have just noticed (not sure why i didn't before!) that compared to my 1975 model there are a three brass vertical tubes, one either side of the throttle stop screw and one on the other side which don't seem to go anywhere, and then when i put my finger over the larger one (engine side) there is a increase in vacuum pressure and the revs increase! Does anyone know what these tubes are for? Should i just blank them off!
Thanks for you advise,
Tony
ps - did not realise that the mixture screw had an o ring.. think i had best go and check that!!!

The larger brass pipe on each carb should be connected to each other, this is the balance pipe. You can use these fittings to connect a vacuum gauge for balancing. The 2 smaller brass pipe on each carb are for breather pipes, ensure these pipes are routed under the tank in still air as turbulence around these pipes can cause running problems. The o-rings around the screws are not essential it will run ok without them, after you fit the balance pipe you should find your carbs will run better.

Glad to hear your bikes running ok, some pictures below of mine, full story under the offroad section of the forum under 'project kanguro moto'. In 2006 I was looking for something different and decided the only way to get it was to build it myself to my own design, so bought a rather tatty 1984 Morini Kanguro 350 X1 and kept the frame and engine and then created this over the next 18 months:-
Post some pictures of your bike when you can.

Wow that looks amazing! Its so good to see something so different and looking so good. Just found your posts on the off road forum and am very much enjoying the story. It certainly makes me more determined to get round to doing something different to mine. I noticed you'd used a vapor speedo/instrument panel. I had been looking at fitting on of these to my sport, mainly to get a more accurate mph reading, was it easy to install? They certainly appear to be a good bit of bit, from what their website say but what your opinion on them?
Thanks again for all your help.

Thanks for your comments, I am pleased with how it turned out. Regarding the trailtech vapor it is an excellent piece of kit, I bought the additional surround with warning lights so it also offers neutral, high beam and indicators. It is a nice unit in that it give speed, revs, trip mileage, time and air temp all on the same display. Again I used the trailtech as my design led my into a dead end and my combination of Husqvarna forks and suzuki front wheel meant I could not use a conventional speedo drive. The trailtech uses a magnet fastened in my case to a hole in the disk ( I used JB weld to secure magnet) and a pickup that you will need to fit to either the fork leg or caliper. You then measure the circumference of the wheel ( I marked the tyre and ran along the road for one revolution and measured the distance) and key this value in. The other handy feature is you can transfer your original mileage over to the new unit.
