Small lever opens a valve next to the spark plug which stops any compression in the cylinder. This allows you to turn the engine over past TDC when starting. I wondered if that was stuck open. TBH I'm pretty new to these myself and also in South West. Is there compression when you put it into gear and try to push it with clutch released?
Breather pipe just hangs down into bash plate I think. Gear oil should drain through hole on bash plate and you should change transmission fluid as well. I will attach basic manual for you shortly.
Had a short chat with the guys at InMotion who reckon it is the crank seals. Pulled everything off with remarkable ease. I love the design of the clutch assembly which came off in one piece. Need to get a puller for the gear on the crank in front of the seal.
I'm hoping my local bike shop MY Motors will have some of the parts on the shelf as Melroy used to ride these things competitvely back in the day.
I have driiled 2mm hole in the filler cap and let the engine cool. Started it and within a few second there was oil being pushed out. I put in 300 cc of oil when I changed the oil as per manual. I fear chank seal gone and pressurising the clutch side. Any pearls of wisdom?
I've washed out with white spirit and refilled. Slightly milky seepage from gear and clutch lever shafts. Undid filler and it is under pressure. Where's the breather?
Golden and lovely. Where would the vent be? Someone said it could be blocked which could have caused the bubbling from around the clutch arm when it first happened.
Just used my 1981white wonder 349 after a couple of months standing.
After an hour of blatting about on a testing trial I noticed an oil leak, which seemed emulsified, from the plug below gear lever and then shortly after bubbling from clutch actuating arm where it goes into the engine case.
I was recently not allowed to enter a trial as I didn't have lights fitted so I'm looking for an inexpensive way to fit them to my Montesa 349. All the wiring is there but all original stuff is way too expensive especially as I will probably break it. Rear light aren't hard to source but does anyone know of a suitable headlight?
Is it really 6 weeks since I spent any time with my bikes? That's what comes of buying a house that need slots of work and also a large bike workshop which is obviously a priority.
Finally having a few hours in the garage.
I have attached the bash plate with the top 2 bolts at the front and as you can see from the pics it sits well low of the rear mounts and as previously stated the rear holes don't line up.
It does also appear too long and I was thinking it may line up better if it was bent a little. Do other peoples bash plates need to be forced into place or do they just fit when offered up? What would be the best way to try to bend the whole plate?
I have offered it up with engine in before I start anything. I put the far left hand screw in loosely and then took this pic from the right hand side looking down. As you can see, these holes don't line up, bugger !
Am I missing something or have I just got the wrong one? I was told it came off a 51M which is what I have????
