If you don't want to see the whole procedure, go to 29.30 for the valve work, but the rest is quite informative. Bear in mind that a dealer was quoting $20k for a new engine, I'm pretty sure this level of detail work would have resulted in a $8-10k bill - but based on what they did and found with parts for the rods at the end - which would you prefer to have (cost excluded)? I agree with his conclusion that most engine problems are "due to the loose nut behind the wheel" - that's brilliant!! 1 Quote
ColinH Posted November 10 Author Posted November 10 No engine work this weekend as waiting for valve seat cutting kit to arrive so sorted workshop and also stripped engine and other bits out of bike. Rolling chassis now. Also found a cracked weld but planning to extend arms and brace anyway, so will sort while I’m down there. I’m also looking at that gap on wishbones and if its correct, doesn’t look right to me. Drawing up my injection inlets at the moment and will 3D print one to see how it looks, fits etc. Im looking at how much of the loom may be no use with location of equipment so may start again. Everything runs to rear of bike then all the way back 2 Quote
Upshotknothole Posted November 12 Posted November 12 There's a spacer between the dog bones that sits in the bearings in the swing arm, is that bolt on the dog bones tight? They're not going to be pressed right up again the swing arm as they have to turn freely. 1 Quote

Thanks for info, I haven’t checked anything yet as just took photo but will get a proper look once I strip the arm out for bracing and extending. Quote
ColinH Posted November 14 Author Posted November 14 Received the Serdi Micro seat cutter today. If the insert arrives tomorrow and I get time to make the pilot, then may get to cut / butcher some seats the weekend. Quote
ColinH Posted Sunday at 06:37 PM Author Posted Sunday at 06:37 PM My next job is to make a 5mm pilot for the Serdi but the very last job on my lathe rebuild is the tailstock, which I need accurate to turn the shaft with centre. So I spent today surface grinding and hand scraping the tailstock base. Following some advice from toolmaker the best way is to turn the pilots true and slightly oversize and then lap them to final size and surface finish. Also got engine mounted on frame ready for piston change once cylinders back from boring. 1 Quote
ColinH Posted 17 hours ago Author Posted 17 hours ago Picked up the bored cylinders today so another step closer on the engine build. Quote
ColinH Posted 17 hours ago Author Posted 17 hours ago I have just noticed the cylinder liners are proud on 2 cylinders. I will have to see if these are bottomed out or have slipped during handling. I would guess if it was handling it would be me and not the company who bored them. They look to be square to block though at a Quick Look so hopefully not bored out of true. I will clock them before and after seating them. Quote
ColinH Posted 12 hours ago Author Posted 12 hours ago I have been working on my ignition. Do you think this has enough energy? Quote
Gixer1460 Posted 12 hours ago Posted 12 hours ago All the liners look to be proud to a greater / lesser degree! Surprised the machine shop never offered to skim / surface the face a) flat and b) perpendicular! Honing angles also look somewhat 'flat' ? 1 Quote

I will check everything is hard home and when it is I will skim on the mill with a light pass. The shop has good rep and both have history is motorsport so work should be good. Quote
