  1. Hi NFC, Unfortunately I think you will have to split the cases as the kickstart shaft is held in place by a circlip on the other side of the case and this looks to have dislodged. The kickstart shaft locates in a bronze bush in the other case and this can wear (as mine had) which may have contributed to the shaft dislodging. Sorry to be the bearer of bad news...

    172 Questions…

    Hi I don't know a great deal about 172's but on my 348 the biggest bang for buck in terms of upgrades were: 1, Put modern roller type bearings in the headstock 2, Get a modern carb an OKO 24/26 will make starting and throttle response a lot better than the old amal that is probably worn out 3, You can get oversize green grip brake shoes that counter the hubs been worn from 40 years of riding hope that helps and not to expensive !!
  3. Got a nice letter back from the DVLA... unfortunately they have no details on there records for my bike. Will have to go through the long winded registration process if I want to confirm the manuals 68 mph top speed!!
  4. If you contact Honda I believe they will be able to give you one cheers B
  5. That's the form, letter and photos sent off .. Fox889 could I ask how long did it take to get a response? Cheers B
  6. Hi Fox889, thanks for getting back to me, I'll give it a shot and as you definetly worth the price of a second class stamp !!
  7. That's a result well worth the effort of writing the letter... Could I ask what office/department of the DVLA you wrote to ? Might give it a shot and see if my 348 was registered in a past life..
  8. Thanks for the info on painting, if I get a finish like yours I'll be very happy! And keep the pictures on the restoration coming...
  9. It's looking good! Especially the tank can I ask did you paint that yourself? got a new tank cover to paint for my 348 and I'm after tips
  10. Hi Joe, It looks like you've done all you can without splitting the cases, if you decide to go ahead and split the cases I'd say its a finiky rather than hard job take lots of photos and make a note of what order the shims in the gearbox are. With my bike it ran well but was noisy compared to other 348's I'd seen at trials it turned out to be the rod/big end bearings that were worn. I replaced the gearbox bearings and main bearings while it was apart these are relatively cheap and available from inmotion (other supplier are available..). I'd never split an engine before so was a bit daunted when I started but the bikes runs great now so I'm glad I persevered with it, there's lots of info on these forums and feel free to reach out if you need any info/tips. Cheers Guy
  11. Hi Joe, I've just finished rebuilding my 348 and there's a couple of things I'd try before splitting the engine. Put in new selector pawls and a shift return spring as they are inexpensive and your current pawls are probably chipped. Take out the detent plunger on the right side of the engine and check the detent spring is free and not gummed up. I'd also take the selector mechanism off and try the gearbox selection with a mole wrench on the selector drum to see what the gearbox is like, then you can isolate whether its the selector mechanism or not I'd also put in fresh gearbox and clutch oil, morris golden film works well in the clutch, you need old style oils not synthetic stuff. Hope that helps Cheers Guy
  12. I've just changed mine as the bikes new to me wasn't sure what was in it before but I put in Motul Transoil 10w-30 Mineral Motorcycle Gearbox oil. And the gear selection is a lot better, used to struggle a bit downshifting before. Cheers B
  13. Here you go just what you were after! https://www.ebay.co.uk/itm/Montesa-Honda-MH349-Montesa-Cota-349-Twinshock-Trials-Crankshaft-Nuts/303881034556?hash=item46c0b89b3c:g:1~QAAOSw4a9gJEAn
  14. Recently put my 348 back together and was looking for the same figures, there is no service manual for the 348 more a parts manual and that just has the torque figures for the flywheel, primary drive and drive sprocket. There is also a clymer manual (which deals with engines up to 1975) but that doesnt cover the figures either. The case bolts should'nt be too tight as there are (or should be) rubber washers that stop the oil seeping between gearbox and clutch. Hope that helps
  15. Good luck and let us know how you get on !!
