overtight engine chains will "whine"........also the eng has its own bespoke noise from the primary drive gears............a whiney sort of noise only really heard when clutch take's up..............and at low speeds...............
whine at eng speed or bike speed?? |

Hi Rich, it was whining at tickover and then builds to a real whine at speed and very loud but other than that....

Oh no!
Don't forget to go through the oil when you drain it - there are often clues in there...

Ok, so yesterday being the complete opposite to today where it's akin to having Noah arriving soon... I managed to split the engine cases and have a gawp inside.  The head and barrels came off without too much hassle with the gaskets intact and also re-useable, I have to get another set of rings though for one of the pistons due to a broken oil scraper ring.   There wasn't much crap in the oil scavenge strainer, some of the white Honda-bond and some blue gasket silicon sealer??  The gear clusters separated when I pulled the bottom case off, there is a bit of foreign matter in the sump area and I found a piece of metal which turned out to be a piece of fin from my original barrels  which were a struggle to get off..  There was major movement of the left con-rod!! Side to side and up and down; the right con-rod just had side to side but both sides shells have no white metal left.  All the bearing shells have worn surfaces so will need to be replaced. I just need to measure the crank for wear and size the new shells accordingly.     The con-rod shells were paint marked green and also a number 2, the case was stamped CCB. This was the first time this engine has been separated fully, so there were no mangled scews or bolts and it was relatively easy to dissasemble. I will clean up the cases and all the parts prior to reassembly. I will have to get a new cam chain, balance chain, oil pump chain, clutch release bearing, Rings, some new seals and shells. Hopefully this lot will be available.  |

Help needed This is the crank, set up to show as per the haynes manual i.e with the web markings they don't match the haynes manual!!!  On the rear of the webs are these markings....  Obviously honda/OEM decided to change the way it marks these cranks??? So how does the little chart work?? |

I think i've figured this out now after my measuring session...
My cases are stamped C C B this is your Datum (this will not change) and this is further broken down into LH/C/RH (left hand/centre/right hand) which is the inside diameter of the hole where the shells sit.
I've measured the crank LH=29.98 C=29,99 RH=29.98 crank measurements will change over time and you should measure at differing points over the entire mating surface.
Next was the crank pins
LH=29.99 RH=30.01
I also found an anomaly, both con-rods are stamped 2 on the side; this is supposedly another datum point.
But I measured them anyway and one was a two but the other should have been stamped a one??
Con-rod 1=33.09 stamped 2 Right side
Con-rod 2=33.05 stamped 2 left side
Just gotta sort the shells out now.
