    Montesa cota 247 ignition

    I pulled all my lighting circuits off years ago but Pink to earth does not sound correct. The circuit is earthed by the points connection to the magneto base

    TLR200 running right?

    The standard gearing on TLR is too high - put a smaller front sprocket on and second becomes much more tractable and manageable - in fact first is only for slow down hill descents

    The kit I mentioned that KBS supply comes with degreaser and yes you need to prepare meticulously

    Cota 247 Tank

    I have used this stuff on many tanks and as long as you prep correctly it works a treat - get the kits for bikes https://www.ebay.com.au/i/272946991608?chn=ps

    Should I buy a 1986 Honda TLR200 that won't start?

    No idea what a Reflex is worth - they are more street trail than trials with smaller forks. A real TLR 200 in good nick is worth well over $1,000 - more like $3,000 in the UK

    Cota 247 Motoplat Ignition Set-Up... Clueless!

    Went to take my 247 for a run today and for the first time in years she wouldn't start. No spark so started working backwards from the cut of switch ...finally removed the low voltage coils and it appears that I have a short circuit to earth. So it looks like a burnt out coil - strange that it got me home without an issue last ride. Does anyone know the correct resistance for the coil?

    Cota 247 Gear Selection

    Underslung clutch went out on Model 21M19228 on LHS an 21M6700 on RHS ..but according to my original 247 Manual there was never a modification from 4 speed to 5 speed. Your model is 21M .???? - there were 6 variants in gear box from model 21M 0600 - 3750 - 5288 - 6600 -7256 and 21385

    Honda tlr 125

    This has got to be close - but your post begs the question, why buy a TLR125 trials bike if you want to do more than 40mph https://thumpertalk.com/uploads/monthly_10_2015/post-378290-0-38088700-1446208661.jpg

    Montesa Cota 247 Break In Period

    There are three tank/seat options ( maybe more ). I have the standard trials body as per your photo - the 247T (trail) body with larger tank and longer padded seat and the later model large tank with very comfy seat. The latter requires rubber grommet spacers for he rear mounts but otherwise fits perfectly and is very comfortable.

    cota 247 hot and cold

    I had similar experience with my 247 years ago - in mine the idle speed also increased - appeared to be running lean but after many many hours and $$$ on the carbie I realised the timing was slightly too advanced and that was the issue. After no luck with depth guage I used paper timing disk - see attached and had no problems ever since. timing.disc.pdf

    Montesa Cota 247 kickstart spring

    The spring has to have some loading on it otherwise it will flop around. The kick start is usually installed at around 2 o'clock rather than vertical. I have only had one spring break and that was when my son tried starting with the clutch in
