malcra Posted May 26, 2008 Report Share Posted May 26, 2008 greetings, as its been great holiday weather in Hereford today, just putting together a Montesa Cota 123 from 1972 (article here). I've not got a workshop manual, so couple of questions as I seem to be chased by electrical issues this weekend. No spark yet, but hopefully by the end of the day. - contact gap ? - flywheel extraction, specific tool, or is it how it looks ? - best manual (there is a Clymer classic dirt bike one that includes Montesa's up to 1976) ? - any idea why I am getting voltage reading to the coil (around 0.6-0.8 volt peaks) and to the plug gap (2.5v peaks) but no spark. - no earth problems (as though its powder coated, have gone back to metal. Back to the shed later.... Quote Link to comment Share on other sites More sharing options...
tryalsryder Posted June 6, 2008 Report Share Posted June 6, 2008 look on ebay, manuals come up for sale now and again. I have one, but I sent it off with my 72 to get worked on. I could make you a copy, but I dont know when I will get it back. I keep the 172 manual with the 76. SW Montesa might be able to run you off a copy. Clymer guides are great for troubleshooting and repairs. Quote Link to comment Share on other sites More sharing options...

tryalsryder Posted June 7, 2008 Report Share Posted June 7, 2008 Sounds like a carb problem, but it could be a lot of things with the vintage bikes. Good luck. Quote Link to comment Share on other sites More sharing options...
