PVL ignition problems

[Turtle.Inc]

Just spent last few hours ftting a New PVL to 440 Maico. Bare metal earths, even run a earth wire from top of frame to backing plate but am getting no spark. set at 2.2 BTDC, turn over by hand and not even a spark when holding on to electrode (new B9EIX plug) ant ideas or something im missing why wouldntspark

Ross check all the lug connections in case one has not been made properly during manuafacture. Also check wire colours compared to your other PVLs in case of incorrect wiring the companies QA should check these things but stranger things have slipped through. I assume you have done all the normal things like disconnecting the kill button

Hi
I have experienced  the exact same problem. I am dumbfounded I cannot solve it. I have two Maico 490   race bikes, ironically one with a PVL and one with the original ignition - the motoplat - this bike starts much easier than the PVL. Originally I bought two PVL'S for implicity and supposed ease of starting- lo and behold the Motoplat with the Bing wins hands down every time. Having said that I also find that if I change plugs frequently using a B8ES -without a resistor the PVL Maico fires easier than with an old plug. I have been meaning to get an iridium tip plug to compare - had no joy thus far
If any one can tell me where to buy a new Motoplat it would be greatly appreciated.
Cold , wet and sore in South Africa (I dumped it earlier today)

Hi Crabman ,  I to have found the same problem , for what its worth I found a fatter spark from a motoplat against the PVL.  If I kicked the bike harder the spark increased on the pvl but i don't feel like starting gym just to start the the beast. just brought 2nd hand motoplat to put back on.

I have previously posted about keys in flywheels and what I do is 1} lap the flywheel to the shaft.2} make a new key out of soft aluminium [like briggs and stratton do]. This gives you confidence that the key-way is lined up. If the engine kicks back on starting and 'breaks' the taper, with an aluminium key no damage should result to the shaft or the flywheel. A steel key will roll up, break the taper and rip the shaft and flywheel about. cheers pancho.

A year after starting this thread and after having the PVL rewound i'm still not happy with it.
The bike is a bitch to start from cold and usually have to push start it first up, not so bad when it's hot.
It shows a weak spark when kicking it and seems it needs to be pushed to spin the engine fast enough to make a strong spark..I'm not a fan of PVL and think a new Motoplat would be the go if you could get one.

For less than half the cost of a PVL, I would get the old motoplat
rebuilt.

Motoplats are no problems to have repaired.
Cheers,

Who repairs motoplat's? I have a couple of them and no-one around here will touch them.

Was going to buy a PVL .

Motorplat sounding better and better.

I only know of two places. 
One in Spain, operated by transplanted Englishman.

and one in the states.

I have had motoplats repaired by both fellows with no problems.

Do Small Motor Rewinds in Melb do them?

[Canam370]

That'll be Small Coil Rewinds in Geelong........had both Motoplat and Bosch done. The Motoplat can often be repaired as long as the insides haven't corroded too badly.
