Lovely build, well done.
Did you not consider going for a dry clutch setup?
A longer g/box shaft and TZ primary cover would do it I think.
Not really, they look smart but it wouldn't be on show and any performance gains would be negligible. If it wasn't going to be fully faired I might have just as a talking point but there's been many more effective upgrades pound for pound on offer.Did you not consider going for a dry clutch setup?

Finally got the head studs, head is now all torqued down.
Clutch all fitted up, pancake clutch pusher mod and ceramic ball installed to eradicate seizing of the clutch push mechanism. Basically in a standard application there's no pancake bearing so the collar can't spin too well and the ball is steel and can gets that hot it effectively welds itself to the push rod.
TZ750 clutch springs and FZR1000 friction and steels too, should hold it!
Next jobs, water pump and oil pump, clutch cover to fit. I've ordered a brand new stator to fit then my lightened flywheel can go on. Also ordering a domino throttle and cables etc. Time to pull my finger out.

That seems like a no brainer really. What are the downsides bar wiring it in? Is an electric pump more reliable in this day and age?
Ceramic ball in the clutch is very clever stuff - simple but effective. How long have people been doing that? Never heard of it.
If you use a good quality pump, like a VW/Porsche turbo pump it's pretty much bullet proof. Davies Craig however......Ceramic ball in the clutch is very clever stuff - simple but effective. How long have people been doing that? Never heard of it.

Not sure how an electric pump can be more reliable than a gear driven impeller. Totally get it from a parasitic losses point of view but I'm not building a race bike.
Modern pumps are very reliable.But they out perform crank driven pumps as they flow a constant rate regardless of engine speed. Kinda handy at slower speeds especially if you combine it with a rad fan from a KTM 2T with a 50 deg switch
Also crank pumps start to cavitate and aerate the water at higher rpm, whereas leccy pumps don't suffer this.
As for the power sapped by a crank driven pump , it's more than you'd think....

Have you got one on your RS?
Yes, once it gets working again.. Turbo pump from a MKVI Golf GTi
Running the standard WP with a big rad I always struggled with the temps. Always ran at about 65 degrees and would hit 70 easily.

Word of warning though. If you do fit one, there will be FACK ALL engine braking!! it's a bit freaky at first butmakes you realise how much power is eaten by the mechanical pump. . But fit a small offroad (ktm/beta) fan and they have a low(50 deg I think) trigger switch. Keeps everything nice and cool.
I'm considering using a DTA ECU for ignition only with it controlling the water pump and fan. It'll ave far more accurate ignition timing compared to the Zeeltronic unit that blew up. Probably just wire the power valves open but could possibly use a standalone PV controller if needed.

Your zeel blew up?? Not good
I think I'm going for ignitech
Yep, but it might have been my fault I think I'm going for ignitech
Sending it off tomorrow for repair/replacement.Not familiar with the Ignitech, but I can say the zeel is a cracking piece of kit. Really nice interface, variable maps, lots of nice features. I'd definitely recommend it

Stupid question, but if the engine fails then does a crank driven pump worsen the scenario?But they out perform crank driven pumps as they flow a constant rate regardless of engine speed. Kinda handy at slower speeds especially if you combine it with a rad fan from a KTM 2T with a 50 deg switch

I suppose a moot point either way, as if the leccy pump fails, again, the engine is at risk big time.
Engine finished, Next jobs are mount the battery and oil tank.
Fitted water pump, oil pump and clutch cover, kickstart etc today... Had a go at kicking it, got some compression!! Also fitted the little brass oil injectors in the carbs... Not something I was looking forward to drilling a hole in a 150 quid carb but did both without any problems.
Once I've got the tank and battery sorted it'll be time to get the ignition done and run in. Fella off the RDLC forum is going to fit the ignitech ignition for me as he's done loads for customers then run it in on the dyno to be safe.
Need to get custom throttle cables made, waiting for my domino throttle to arrive.

ker running this weekend, not 100% but I've got a standard CDI on loan to throw on so should be able to get it fired up. Fingers crossed.Gassing Station | Biker Banter | Top of Page | What's New | My Stuff
