Thanks dogbunny, might make it a little easier to locate locally.

So I’ve stupidly misplaced the rear master cylinder dust boot on my 1978 xs650se - are these the same as many other bikes? SR500? I’ve got a rebuild kit from mikesxs or geoffsxs here already but it stupidly doesn’t have the dust boot included in it, hopefully SR500 are the same and might be...

A little late to the party but I just found this same guide myself and wondered if anyone had posted it here. I had signs of being lean in one area while rich in another area after tuning on the dyno the other week and might have to run through some of those suggestions on the guide to get...

Sounds pretty good. Still need to dial the timing in a bit closer.

Yeah budget is a little tight as should really be spent on family things but have an old dingo skid steer sitting there unused so it can go on trademe and bike parts budget will be good to go again. BRM was a few hours drive so not ideal but he’s good chap and fairly patient. I’ve only dyno...

Hey Signal, Thanks for advice. Presume I could just try heavier springs and a bit of roughening the plates up for first go then 8 plates if still happening? Brett adjusted the carbs to where they are now on that last blue line on the dyno, seemed pretty happy with that as far as he could tell...

Finally got to putting my 277 project on the dyno today but clutch was slipping from 5000 to 6000 rpm range onwards. Is it just heavier springs needed or the actual plates or both likely need upgrading? It has fairly new plates in it but just the normal ones from Mikesxs. I’m guessing...

No prob! Didn't realise there was someone else doing them, believe Daryl had stopped doing any quite a long time back.

This wasn't Daryl then? I just saw this post here and also the lack of responses to any enquiries and presumed he'd passed - https://www.xs650.com/threads/large-quantity-of-xs-650-parts-available.62934/

Will do - it'll be handy having dyno there to prove what's working best. It was actually built by Daryl Hutcheon who did the 270 crank pins but he'd stopped doing those by the time he did my rephase and only offered 277 rephases I believe. Lack of demand and cost of additional parts for the 270...

Thanks Gary & Signal. Will give that a go. Taking it to a Brett Roberts dyno next week for some help with jetting carbs and general fine tuning so just going to get it starting before that.

Thanks for the reply, good to know other ones out there are done that way too. It all seems correct other than the old ignition which I’ve now replaced with trispark but haven’t fired up since installing. When firing it up my static timing may have been a bit rough but shouldn’t be far off, had...

Is there a reason most things I've read on engine rephasing mention the right cylinder firing 277 degrees after the left (or left being behind right by 83 degrees) rather than the other way around? On my 277 engine the left piston fires and then 83 degrees later the right piston fires. Is it...

All good, thanks alot!

Nice. Haven't made it to the Boxing Day racing there but looks great. You don't know anyone in NZ with alot of xs650 spares? Just chasing a front brake disc as had one of mine pinched or lost while it was in storage.

Thanks Signal. Great thread. What part of New Zealand are you in? I'm based in Mangawhai, north of Auckland a little. Will try update my details so it doesn't say Melbourne any more.

Short question for the well learned around here - is it 15 degrees from TDC to fire and then 25 degrees from fire to full advance? (40 degrees from TDC to full advance?) Installing a new tri-spark ignition on my 277 rephrase project and TDC wasn’t marked when the PMA was installed. The ignition...

I haven’t rebuilt a bs34 but I believe most or all of the stuff is available at mikesxs? They have new slide and diaphragm but it is like $100 I think, that seems to be the bit that craps out most critically. Someone else who’s actually done this will have better info though, just thought I’d...

Thanks for the reply - valves all seemed okay, turned the engine over occasionally while stored. Good idea storing with valves uncompressed though. Checking it again it actually reads 120psi on either cylinder when testing with the spark plug out on the opposite side but about 150psi with plug...

Hey All, I've got an engine that was rebuilt a few years back with 750 kit and a 277 rephase and then ended up having to store it for a couple years due to other priorities. After changing the oil I did a compression test on it and one cylinder read low (90 psi) for maybe five or six tests...
