threaded insert / nutsert / rivnut spinning in the frame, had to drill the head off the bolt, what a bastard of a job with blunt drill bits. yeah those rivnuts are absolute bastriding things. pulled it out the frame and got a shot of a rivnut gun. bit of an awkward tool in comparison to a regular rivet gun but yeah there you go for anyone who's never seen one. fresh nivnut in the frame. winning at life haha couple of pics with the wee stubby on before i dropped the headers for cleaning and whatnot. probably a good thing water boilers don't make as nice a fighter as the oilies with the radiator overhanging as its far too good for it. heres hoping i don't put it down the road.

just the usual trials and tribulations when dealing with header bolts but yeah pulled the headers for a well overdue clean. wire wheels work wonders, I've since found out that wonder wheels or any wheel cleaning acid does a damn good job at cleaning headers but i think these were beyond that. countless hours. excuse the pic overload haha shiny shiny, still to hit them with a fine sanding pad and give them a wipe over with autosol. certainly back to good health though.

pulled the carbs for a quick clean to get everything running right before changing anything. airbox is a bit of a bastard when re-assembling but its really not as bad as they're reputed to be. gave inside and out a good clean, quite surprised at how tidy they are for carbs of that age, really inside there wasn't any reason to justify how the bike was running. however all 4 needles were on their lowest setting, manual calls for clip-2 if i mind right. 2 diaphragms were pinched in the caps, the 2 needles connected to that had some scoring. air mix screws were all over the place, cyl1 = 2-1/4 .. cyl 2 = 2-3/4 .. cyl 3 = 4 .. cyl 4 was seized and the head rounded but yeah whoever last touched them needs a skelp. no wonder it was running lumpy and a bit down on power. got the dremel out, but the bit down then notched the mix screw. problem solved. fired it all back together, run much smoother just needed a balance

cheers dude. yeah i love LOUD but i genuinely winced haha its harsh as fuck.

theres a few sources saying very different things to be fair, thanks for backing it up rather than adding to all the speculation out there definitely interesting to see a side by side comparison in cam specs. thanks dude. I'm sure i had read up on the 6 speed swap ages ago and longevity problems when used hard isn't going to be worth the hassle is it. that was off the table pretty quickly. // so my knowledge on cams is pretty basic having never really dealt with them hands on and I'm not going to pretend otherwise but in terms of comparative figures the 92 750's EX is a close match to to the 95 onwards EX except it looks to have a much longer duration like you said, actually both in and ex have longer duration. this stuff is slightly beyond me, will have to get my head wrapped round it. initially i was looking at it thinking i could use the 750 EX alone in the 93-94 but I'm not sure about overlap or any other factors that may be of issue. if both 750 cams are longer duration it could be worthwhile looking at using both at the loss of 0.1mm lift on the IN side in comparison to the later 11 setup I'm aiming for if my understanding is correct. i'll need to figure out what engine exactly it is thats sitting as I suspect the cams were probably changed at some point in the 750 W's production. // any known matches/setups or well educated speculation is welcome though

haha ohhhhhh i know it too well man! i'm 16 months into my other ''winter project'' at the moment keep finding new projects to distract myself with and theres always something needing sorted. hoping to have all 3 bikes roadworthy this summer.

gave all the disk bolts a good clean up with a wire wheel whilst they were off, ended up having to replace the rears as a fair few were rounded or starting to go. picked up a titanium set listed for fitting 89-92 but its the same dimensions for the watermelons bolts. shite pic but yeah ti bolts I'm sure that will make a massive difference to the bikes weight problem... hahaha nah in all honesty they were cheaper than a steel set which is crazy, otherwise theres no danger id be wasting money on ti bolts. its also impressive as to just how light they are in comparison. // so... i had a twice crashed and mangled old remus innovation can wedged onto my now winter hack gs500 which was the exact same can on the 11. those old remus cans are a bit of a pain to work with as the link pipes are 80mm odd where they join to the can making it difficult to find another slip on as they're typically in the 50mm range it seems. anyway i gutted the reflective baffle can and robbed the ends to build something up. can't find a pic of it before but it was a rashed up dented mess of a can and you can't really stubby cans with reflective internals easily or well typically, although i'm guilty of doing so in the past. using leftovers from a viper i had previously stubbied, i robbed the external alloy sleeve (about 8'' in length), packing and the internal perforated tube. this is where it gets a bit interesting. because the remus's entrance (where exhaust gas flows in) wasn't made to mate with this absorptive race can style internal and that the 80mm odd bit is so massive in comparison to most cans i had to make up a wee plate. nothing special, just a bit of tin i could cut to to size and was soft enough to bend slightly when pressed together to help seal it up if you follow me. i don't actually have a pic of the remus entrance to show but when you see the can complete and on the bike you'll know what i mean surely. notched the tube and bent the tabs grip the plate. plate looks rough but when you're working with minimal tools you do what you have to haha. the finished can more than tidy enough. so obviously that plate pressed against the entrance as the can was pressed together, instant gasketed up and riveted. really, its just a bit of an experimentation as I've never seen or heard of reflective baffled cans being converted into absorptive 'race cans'. really it wasn't all that difficult to knock together and if the end plate doesn't hold for whatever reason then its not hard to pop a couple of rivets out and redo it. good fun either way. just to show the size of the link / entrance in comparison to the perforated tube and if you look at the old internals the end plate was welded into the rest of the chambers, which is what i needed to emulate to keep the packing in. it was damn loud before but yeah... its seriously frickin' loud now, almost painfully so. sounds proper mean like an 11 should i'll just need to find a decent hanger, its difficult to do so as the 11 has an awkward spacing and the aftermarket isn't exactly as it would have been in the 90s. //

for sure, acid etch and high build primers are life savers in my book just wish i had the space for a proper painting set up. yeah thanks guys easy to underestimate just how much time goes into stuff like that. for a post you can glance over in 30 secs, theres about a months worth of weekends and every other evening put in haha definitely needed done and I'm glad its paid off

cheers dude and okay mum haha aye so i got my hands on that beastie ^^ probably paid a spot too much but they don't seem to come up often, its a ws 750 and its either 40mm shorter, 60mm or 2'' depending on who's measured it online haha either way its a spot shorter and i'll get an accurate measurement myself when its on the bike. manky, bit of corrosion bit scored but the rear axle, calliper / bracket and chain guard present. just missing the dust seals, thrust washers and the rubber chain buffer. i had planned on part polishing the main faces and leaving all the hidden stuff protected with the factory finish but damn that factory coating is tough. started rubbing it down but couldn't be arsed really tried a few things then ended up getting my hands on some brutal paintstripper, the kind you can't buy off the shelves in the uk and it still wouldn't touch the coating. so the part polish got abandoned and its getting blasted back and powder coated now. // tyres were desperate and some very clever person thought it was a great idea to lacquer over the polished lip on the wheels many a moon ago. needless to say its a hell of a flakey mess nowadays. so that was the next job. ^^ and you wonder why it handled like a fridge... ridden worse on smaller bikes but they're well passed it. paintstripper basically wiped the old lacquer off... left some marks from the flaking etc but its good stuff haha won't put so much faith in masking tape again, stipper bled through slightly in places. stripped prior to sanding in comparison to what it was like before. front wheel masked, painted and lacquered no bother. just aiming for tidy at the moment, not shooting for perfect. hope to get them powder coated at some point, just didn't want to pull the bearings etc so paint will suffice. and in true ''everything seems to be going well'' fashion the rear reacts. think it was down to a bad batch of primer as every time I've touched that tin i got a reaction, 3 separate times it screwed me over. flattened back. acid etched, no longer taking chances. painted, lacquered, painted edge cut back in and machine polished lips. you'd never guess the back reacted so badly, not perfect but a good save i reckon. fresh pilot power 2ct on the rear and a front to match i had lying around. spot of tyre detail put in, didn't fancy going over the top and doing all the lettering, just kept it subtle. oh yeah, i like taking pictures so this will likely be pic heavy //

noted, the 750 cams are meant to be hotter than the later 11 ones, thanks man. any builds or documentation that you know of worthwhile checking out? I'm usually on the ball with finding stuff but no real luck with anything cam related. found a reference to some magazine build talking about them being usable but not much more than that. funny you should say about the 6 speed box, i was thinking about it earlier, literally was just about to look it up haha that could be really interesting to do.

good to know man! cheers, sounds like i might have a thorough raid of it. really curious about a cam swap as the earlier wc 11 cams like mine weren't as hot as the later ones or so I've read. if I've got access to the 750 cams its a free gain if its worthwhile doing.

yeah so, long story short an 'unrelated forum bike' spat me down the road at a hundred and silly in what used to be my favourite corner haha and i sort of wound up inheriting an 1100 wp when i got out of hospital. the old man's circumstances changed, i was without a running bike / with many a project to be finished and i wound up with one of his bikes basically. bit weird, not really used to having things handed to me. have a soft spot for golden era bike looks but i didn't think this was my kind of thing with it being a big, heavy water boiler. wasn't even sure if i was even going to keep it but as it turns out i fucking love it in spite of its many flaws. pics really don't do the thing justice, it was proper tidy for a 93' w/ taz racing relentless livery. put a fair few miles on it at the arse end of summer. carbs were desperate for a clean and occasionally dropped a cyl at idle but was fine once warmed up so i ran it as was till winter kicked in and i had time to take it off the road and play with it, it pulled strong but not as strong as it should, pulled to redline in 5th nae' bother and crazy stable in the high speed sweepers, tyres were fucked about 6 years ago before i got it, well out of date and squared off, terrifying to ride in the wet for sure, shouldn't have been riding it like i was or digging into the old man's chicken strips, brakes were a bit sticky but other than that it was mechanically sound and like i said very tidy overall. just had new discs all round, a recent chain/sprocket set, what appears to be a full stainless 4-1 remus system, braided lines and hyper pro shock. parked up as soon as winter kicked in and out came the gs5 hack. // I'm about 5'' 11 / 6ft and riding the 11 is like sitting on a witches broom, agony on the knees after 30-45 mins so I'm thinking about dropping the pegs 10-25mm just so its a bit more usable. other than the riding position being extreme and its weight the biggest flaw is that it handles like a fridge, really need to keep it on the throttle to get round the corners which is probably down to a combination of the suspension needing setup and the tyres being well passed it. so anyway... after a bit of research i decided on and managed to find a braced arm from a 750 ws at reasonable cost and I've been putting the time in so i'll throw a writeup here for anyone who's interested. nothing that hasn't been done before like. already a fair bit into sorting the old beastie out but i'm not posting everything at once so updates are to follow //

Alrighty guys, Been lingering here for a while now. running/building a WP 1100 and I've been offered any engine bits that are of use from a water boiler 750 engine getting broken down from a member so info online is pretty vague on the cams but it has been done, anyone able to comment on gains? any other bits like casings etc compatible does anyone know? thanks,
