Well i discovered another little difference today - it appears that the classic and meanstreak have different generator (alternator) the classic has two circuits and uses two regulators/rectifiers whereas the MS has only one and uses a single rectifier. How do I know this? Well I seem to have a spare connector coming from the generator so I consulted the manuals. As some of you already know, my MS is actually using an older classic engine (1999 engine). it seems that the Meanie doesn't have the inner alternator and thus has only one set of connectors (pick-ups, alternator) whereas the classic has three - 2 x alternators plus pick-ups. This gives me a question to answer with three possible solutions: 1) Replace the alternator with a correct Meanie version - problem solved. 2) Use two rectifiers and splice the return outputs from the second rectifier into the connector for the other one (MS doesn't have two connectors for two rectifiers) 3) Connect up only one of the alternator circuits and tuck the spare output connector out of the way. Any thoughts? Obviously solution 3 is hte cheapest since it means I don't need to source anything. I should have spotted this issue earlier but I only really noticed it today whilst connecting up the electrickery. Pictures: two alternator outputs - The MS wiring connector will actually only properly fit the "outer" alternator connector One connected up:

Problem solved, I sorted through my spares boxes - I have the correct alternator and correct MS flywheel. Bad news is that means I have to strip that all out again, would've been much easier if I'd known this before sticking the engine in the frane, it can be done in the frame but it's a bit fiddly, have to undo front and rear engine mounts on that side to be able to lift the engine up enough to access the cover lower bolts. Need to make new gaskets again!

Crap man I feel your pain but I was other way around. I had to mod the classic harness.

All done, not too bad a job, made easier by the fact that I did this only yesterday so it was very fresh in my mind. That Meanie flywheel weighs a LOT more than the classic one.
Anyone, all done and all buttoned up now, I don't have any spare connectors left over, just the two that I'm puzzling over (see other thread) and I think at least one of them must be for the tail lights sub-loom

Might be interesting putting the lighter flywheel in the meanie. If these had a higher rpm range it'd be a very rev happy engine.

I'll ger you the weight of the classic flywheel and gear today, no problem. Not sure what you mean in your last post, did you want the engine number?

No, the inside diameter of flywheel

No, the inside diameter of flywheel Ok, I'll get you some measurements tomorrow

Ok, got you some measurements, metric of course ;-)
Gear wheel = 892g Flywheel = 4.25kg Int. Diam. = 131.5mm *
* as accurately as I can measure with my crappy vernier. Weights should be accurate, I used the kitchen digital scales
Let me know if you need anything more. Cheers

A Big shout out to Colin and a massive thanks for all his help today. Between we think we've tracked down the cause of my no spark problem. We discovered that the Meanie and Classic flywheels are quite different - the outside diameter of the Meanie wheel is a fair bit smaller than the classic meaning you can't swap them over unless you swap over the outer cover as well - otherwise the flywheel trigger is too far away from the pick-ups resulting in no signal output to the ECU = no spark!
We were partly on this road earlier but then got side tracked by investigating the ignition coils before Colin took delivery of his new Classic flywheel and noted the smaller diameter, something I hadn't noticed when I swapped my Classic wheel for the Meanie one. So, tomorrow I'll be swapping the flywheel back over and hopefully, fingers crossed that will give me a spark and a running engine.
I might eventually have got there without Colin, I was planning to swap the flywheel back over simply because I couldn't find anything at all wrong but with his help we tracked down the issue much faster. Thanks again Colin!
