Opening that can of worms
K2-K6:
Tentatively, looks like it may have the unique to F2 oil cooler plate behind filter housing (can't quite see in picture) which could mean F2 bottom end, or fitted to replacement engine as it's just a longer bolt used. Engine number will show case type anyway.
Top "shelf" of head fins look more like K series as the F2 extended out more toward front wheelmin giving more cooling to exhaust port area.
As Bryan notes, could be K top onto F2 bottom end .... or K painted black to look like F2 original.

so i have been in the garage for half an hour or so tonight, started stripping down the rear end, only because that looked the easiest, starting to get a bit more of an idea what parts i am definentely going to need, and what parts can be reused. ideally i need to get all the bits off that need sent away to be rechromed, all the frame black parts i am just going to clean up and rattle can, the frame will only need touching up in places. not 100% sure what i am going to do with the wheels yet. the engine is still an issue too, a lot of the engine/clutch/gearbox covered have been removed before i got the bike and i dont have the bolts that holds them all on, so if anyone can recommend a bolt set with alan key heads that will come in handy that would be great. i will order a box of M6 and M8 bolts in different sizes so i can change ones out as i put it all back together. the more i look at it and as bits come off im getting less and less scared lol

Personally I prefer SS bolts to the Allen Key Headed ones. If you use AKH bolts on the top of the engine they hold water and fill up with dirt over time. Lots of sellers that do kits so you get a similar length replacements.
My 500 was already fitted with SS AKH bolts so to save on costs I just replaced the top casing ones. Not bothered about the side covers being AKH ones.
If you look in the parts book the part number contains data indicating the length and thread size in mm, not the thread pitch though. If you search here you will find previous information. There is also a code for if the bolt was Chromed, BZP etc.
By looking in the parts manuals you can see the order of the parts for the clutch assembly order in conjunction with workshop manuals.
Hope you took plenty of photos as you dismantled stuff, easy to think you will remember how it went then months down the line doubt creeps in.

its all bigger stuff i have removed so far, so there will only be one way it can go back on, is there a download-able parts manual, if so could you send me the link, unfortunately some stuff was already stripped before i got the bike, so they will be a bit more tricky to put pack together, but i will get there slowly
