  1. I have just stripped the carb to see what was in there! Slide - 2.0 Main Jet - 130 Pilot Jet - 32.5 Needle - 5DP7 Needle Jet - 182 0-8 Main Air Jet - 1.7 From a google search I found somebody running the same apart from he had a 35 Pilot jet.
  2. The carb was supposed to be jetted to suit the bike so I am not sure what is in there. I know the needle is a 5DP7, but I think I will have to strip it down to find out the rest. The Mikuni is brand new.
  3. Hi Guys, I am after some advice regarding my 1979 Mk1 349. I am about 98% finished with my restoration but I have a slight issue with it. I have a new Mikuni carb fitted instead of the Amal. It starts and ticks over great. If I rev it a little bit it comes back to idle nicely. If I open the throttle fully and release it, the revs hold for 4 or 5 seconds before returning to idle. Throttle cable is not sticking and I can hear the slide in the carb returning onto the throttle stop screw. I have tried the clip on the needle in different positions but it is still the same. Is this a fuelling issue or is it sounding like crank seals? The crank seals were supposed to have been replaced before I got the bike, but you never know! Am I right in thinking that when the revs hold it is running lean? Or is this normal? I have never had one before so I don't really know what it should do haha I have a short video clip I could email to somebody if that would help diagnose the problem.
  4. Thanks for the reply. I have got the kickstaft as far out on the shaft as the bolt will allow. I will dig out the old one and compare, I suspect it is not quite exactly the same as an original one. Few pictures of the bike as it is at the moment and during the project. Still a bit to do yet!
  5. Hi, Could anybody shed any light on why the kickstart is fouling with the rear brake lever. It is the original brake lever and does not appear bent or anything. The kickstart is a new item from Inmotion that is supposed to be the correct one for the 349.
  6. Hi, Could somebody please have a look at the picture and tell me how the bottom stud is fixed in. At the moment it just turns not allowing me to tighten the nut that holds the bracket on. The top stud is ok. Is this a full engine strip down to fix this? Many thanks.
  7. Thanks for that 'feetupfun'. Does it not loose a bit of oil out of that hole then? especially if you are climbing???
  8. Nobody know anything about the hole shown in the picture above? Should it be plugged or something? Cheers.
  9. Many thanks for all the info received so far guys, it is much appreciated. Today I noticed a small hole in the back of the engine. It is 2.5mm in diameter with no thread. Should it be there? Does anyone know what it is?
  10. Thanks for the information so far guys. I have two quick questions. In the picture below it shows the blocks fitted to my bike for the foot pegs. Do you think these are the original blocks? If they are I can't figure how the springs are supposed to go. The springs were loose in a box when I bought the bike. In the second picture, the main drive (output) shaft where the front sprocket goes on is leaking oil. Is this a big job? And is the seal accessible from the inside?
  11. Thanks guys, thought it might be chrome plated. I wouldn't mind seeing some pictures of a completed bike! I am going to have a few problems with a few bits...... 1. The bracket for the front brake arm is snapped off the left fork leg. Will need a new fork. 2. There is a little bit of oil weeping out of the gearbox drive shaft (where the front sprocket goes on). Is this normal or a big job to change a seal? 3. Not sure if it has correct footpegs on.The guy gave me the springs in a box as he couldn't figure how they went on! 4. Will need a new airbox cover, this one is cracked. 5. Rear shocks don't seem correct, can they be serviced or do they need to be replaced? 6. No idea what the front forks should feel like? feel a bit bouncy at the moment haha 7. Chain tensioner is missing 8. Electrics for lights to figure out. 9. What joints the main two pieces of exhaust? These were just pushed together with loads of exhaust putty! Think that is about it. The rest of the parts are available, mudguards etc. Think no 1 and 2 could be the problem ones!
  12. Hi, I have just got my first twin shock trials bike and intend to do a full restoration on it.....I fact I have already stripped it down ready to get the frame painted. No doubt I will have many questions as I start to put it back together, but I just have one quick one at the moment. Could somebody tell me what colour the upper engine support bars are supposed to be. Are they polished or painted silver? Apologies if that is not the correct name for them, but they are the bars that go across the engine at approx 45 degrees. At the moment mine are black but I know that is incorrect. Many thanks.
