Thanks for the reply. I've been in touch with Electrex who are baffled by the situation. The gearbox has got to come out as it is leaking like a sieve and I've only got two gears when I prod the gearchange lever, so I'm separating it from the engine and taking it to the Telford show so that they can have a look at the timing. Should have stuck to Japanese bikes in the first place-eh!
British bikes are a love hate kind of relationship.
With the advent of the new year, I've decided to treat my bike to an engine rebuild. I've done other bikes before, but never a 315...
Is there anything I should watch out for, or is it fairly straightforward? The engine sounds noisy, not rattly as such, but just like it's not running smoothly. Any idea on whether top/bottom end is most likely to have gone? Are the Montesas particularly susceptible to either? It's certainly noticeably more noisy than other Montesas I've listened to.
Also, whilst I've got it in bits, is there anything I can do to the internals to improve power??
Any help would be greatly appreciated.
Cheers,
Ben
Ear plugs, seriously if its just a bit noisy I would think twice.
I started this ,because of the comments made by the westmorland club on their results page. My wife used to observe, but no more you can guess why.A solution could be, that if a club was doing a club championship of say 5 rounds ,10 sections thats 50 observers.To enter the championship you have to nominate which event you are observing.4 events would count .If there were more than 50 entrants there could be a lottery, or entrants could be given tidy up duties , help set the course, this also aleviates the problem of the hardy few doing everything.
Lanarkshire club has Rule 9. Every rider has to nominate a round during the year to observe.
Hi, this looks very much like a compression problem. Head and barrel off and check the rings, one may even be stuck in the ring groove. Stuff a rag down the crankcase before lifting the barrel right off in case you have a broken ring. That way the bits wont fall in the crankcase.
Incidentally the other cure mentioned about taking the plug out and kicking it over a few times purges the crankcases of unburnt fuel. Nothing to do with the electrics, i would suggest.
Just thought also may have a coked up exhaust port. Again this can be scraped out when the barrel is off. hope this helps.
The capacitor gets charged up if you kick it over with the plug out, when you reconnect it you get a better spark.
When i got the bike it did have a full kick,its because of the kicking back the problem with the kick start has come about. It has lost some of its stroke when you kick it, and if you bring your foot up fast and go for another fast kick its just slips. The stator has apparently been checked and repaired,sparks same place every time? A friend of mine has a 08 290 and kicks it gently,2nd or 3rd kick it starts. Do 250's kick back? When i kick it over it seems to have a lot of compression.
A worry i have is that if i sort the kickstart problem and it still kicks back,it will damage it again. Another idea was to swap stators with my friends 08,also check timing with a strobe.
I try to engage the starter gears befor kicking it over, thinking being that its easier on the brive train.
With my impact wrench, as Andy T said, a slight twist in the anticlockwise direction (assuming normal thread) means that when you hit it, all the force goes into the nut, hopefully undoing it.
If youve got a fancy tank breather take it off, might just be blocked and stopping fuel going into carb, if thats ok check the carb itself is flowing fuel and the floats arnt stuck, all this though assuming you have a spark. Sometimes its tricky to see a spark in the day, best way is to try at night it will soon show.
The real mans way to check if theres a spark is to hold the plug, ease over gently, you'le soon know if its getting power !
