The bike has the clutch mod already :-) I felt the full effect of a buggered basket backing plate on the way back from Le Mans in 87 I think it was. Buggered most of the bottom end.

@Mr farty Any chance of some more photos of your bike? Im in teh process of stripping my EX and am looking for inspiration. :-)

Racecraft = Racefit?

Mine was a 1977 Orange TS125. Loved it. Wish I still had it.

@Mr farty The journey is half the fun.

No chance of a cheap 750 engine where I am. I just split the cases and the crank is already welded. The gearbox looks good, to the naked eye anyway. I'm at that stage where I have two cases and a billion bits (labelled) in various boxes and I'm thinking "Ah crap, am I ever going to get this together again?" :-) I did all this 28 years ago when the clutch basket went on the way back from Le Mans. The bits took out the crank bearings and a few gears. So I know i'm up to it!

So, I'm thinking this: 1170 (as now)G3 cams or "Yoshi cam profile" (regrind) And welded and reground rockers. £400Case breather £60RS36 carbs £765 (What the bike cost, pretty much...)APE Camchain tenstioner £50Jaygui pipe (or Racefit legend if I win the lottery...) £850 / £1350Pingel, maybe. Won't be doing that many "Banzai runs at 180" :-) £110Will (try to) get the crank checked and welded GSX750 oil gears, they're very pricey. Worth it for this level of engine? £250!!!Dyna 3 ohm (green) coils with silicone leads and Dyna S ignition, possibly. £275This gets expensive quickly, but hey, the wife wants a horse. For THAT kind of money I could buy and run a Moto GP bike. :-) /Phil

@matt Ah, yes, the taper would make sense I spose. Not like this then: https://www.youtube.com/watch?v=v8mMQbEkr8w

@coombehouse I might ask him to do the cams. I'd love to go the whole way with valves etc but I'm in Sweden and shipping the head over is a bit expensive :-)

@Gammaboy That sounds like a good way to go. The big valves sound like a kerfuffle and I don't know any tuners over here to do the work necessary though. How were the RS36 es to set up?

Any idea why the downpipes are welded half way down? Looking at other systems they seem to be one piece from the manifold to the junction. Especially the fancier hand bent stuff. But even my old Harris pipes looked to be one piece.

Less noise? I don't understand :-D Seriously though. Where I live I can easily ride with an open pipe.

So, I have an 81EX I bought a few yeras ago. 14 previous owners bit rough round the edges, but it goes. I'm stripping it over the winter and planning on making it a stronger and reliable bike for next year. I'm in Sweden, it's a short season over here :-) I'm thinking Bandit 600 forks for the front with decent springs and gold valves, probably a bandit swing arm. Not sure about the wheels, the selection is limited over here. It already has Öhlins shocks. The engine is an 1170 and the bores look almost newStandard cams (looking slightly worn)The rockers are worn, will be having them welded and reground by Phil JoyStandard carbsPod filters Standard exhaust!Clutch has re-enforced and welded backplate and new center basket.I haven't split the cases yet so I don't know the state of the bottom end. But there were no funny noises and the gearbox was fine. So, to my point. What are some common sense mods to the engine that will leave me with a stronger and reliable lump for the summer? Cams? Which ones? (don't fancy bigger valves, looks very pricey)Carbs, which ones?Porting, "worth it" for street use?Would I need better coils?Fancy oil cooler? When do I need fancy head studs?Exhaust, obviously. Not many people where I am/ride so noise isn't an issue.I'm interested in a crisp rorty bike that won't need race bike levels of TLC. I have a KTM 450 for that :-) Something like this, but a bit "less" so :-) https://goo.gl/hrzSBf Phil

The website is still up, but then that actually means nothing :-)

Looking for a new exhaust for my GSX1100EX, don't have the wherewithal for a Legend and googling around, as you do, I found their site. http://www.rastec.nl/OLDs_COOL_PARTS I like the look of the pipes in the photos. Not a fan of the welds on the down pipes though. Anyone got one/had one? Heard anything about them? Phil
