    It's not difficult, just time and practise oh and gas

    Tig Welding

    Have you played with a tig set yet? Compared to mig it's like meditating whilst doing yoga, so relaxing
  3. Unlikely, the big one for me was the mortgage, the f**kers had sold it as part of the life insurance. If you've had a credit card it might be worth the ask
  4. So I finally got off my arse and submitted some ppi forms, 5k back into my bank with 1 more to come in Time to by the wife a cargo trike
  5. So hanging around the dockyards at night has proved fruitful again?
  6. Got up at 5:30 Wednesday for the drive to Cambridge, arrived at 9. Tested solidworks, went for a curry and beers till 1:30, up at 7 this morning, tested through till 5, talked to a man about cargo bikes for an hour and drove home for 9. I'm shattered but it's been an awesome time, looking forward to going back next year if they'll have me
  7. Tommorrow morning I set off earlyish doors to drive to the dassault systemes uk hq in Cambridge as I've been invited to beta test solidworks 2019. One to one discussions with the devs with the chance to make suggestions, bug hunt, talk to people and play with pre-release software Being put up in a hotel overnight, taken out for dinner on the evening and will likely catch the second half of the match* in the pub afterwards, all for free Rather excited to go play with it *I can't stand football ordinarily, the stupid salaries, attitude, acting and general f**kery that goes on disgusts me, much prefer rugby but the world cup is always a bit of fun!
  8. It's always fun stripping motors, especially broken ones
  9. Chuck it, with that much potential debris swilling round the sump it could have got anywhere, doesn't take much to block a pressurised oil line. If you want to take the time to completely strip, clean and inspect then I dare say some bits might be reusable, but it's a 50k motor, it's at end of life anyways. After the ccm lunched itself, I stripped the oil pump to try to find the source of the starvation, the sides of the scavenge pump rotor (dry sump, oil in frame with a double trochoidal oil pump; one rotor pumps round the motor, the other scavenges the sump back to the frame) were scored from previous debris that had been passed through. There were cavitation witness marks on the rotor lobes and it had obviously been a long standing issue, just didn't rear its ugly head till what acceleleration at 110mph. A testament to the robustness of the rotax motor that I rode it the 7 miles home after nipping the little end and destroying any form of ring seal or bore
  10. Nope, plenty of the old oil burner gixxer motors have been sploshed with smoothrite over the years. Engine cases get hot but not that much above 80°C at a guess. This stuff is also very good albeit more expensive http://pj1.com/i-19004782-pj1-fast-black-engine-and-case-paint-500f-satin-black.html
  11. Smooth hammerite, paints engines lovely
  12. What's the oil system? When the ccm seized it was just the little end nipped up because the scavenge pump had cavitated and pumped the entire oil tank into the sump (rotax motor is dry sump). Fortunately because the rest of the engine was full of oil it survived unscathed. The little end nipped because it's sprayed by a jet from the underside, the jet is an integral part of the oil pump and lost pressure first. Pull the motor and head, it might come free but chances are the cost to rebuild will be more than a scrap donor bike/engine. 51k is a healthy innings though!
  13. @ben_travis Still using the old king discgotech I got off you on ebay back in 2004ish
  14. 12 years old, positively ancient as far as silly seatless bikes go
  15. Ah but we've been together for 6 years and known each other for 10
  16. Got married four years ago! Still married, not divorced, not buried under the patio! Must have married the right one
  17. There shouldn't be any oil on the shock body/stanchion at all, time to get a new shock!
  18. After the oil scavenge pump on the supermoto failed and lunched my bore/piston/rod I was looking at having to replace the cylinder (500+ quid - overbored nikasil plated aluminium cylinder); the bore had been gouged out at least a mm in places, plating was shot and there was some broken material at the head interface. I was recommended a local place that does a lot of 2smoke refurbishment and tuning. Spoke to them about putting an iron liner in and he didn't want to touch it as there wasn't enough meat in the aluminium to support it long term. As it was they took the old cylinder, ground out the remaining nikasil, welded up all the damaged aluminium, machined, replated and honed. Cost 193 quid all in! As that looks like an iron cylinder I wouldn't expect it would be too onerous to get a sleeve put in there if the the patch/remachine repair isn't viable. You really need to speak to a good engine shop. It was PJme that did my work, it did take a while to get done due to work load (about 6 weeks I think) but it was worth the wait. http://www.pjme.co.uk/
  19. Cylinder is easily repairable, a bit of plate welded in, machined back and honed should be good; there's no stress on the skirt, you might even find that the piston doesn't even sweep over the broken section hence why it's been left as is.
  20. Shonky fox shock, my cane creek just works I wouldn't presume that YT would send a replacement bike but an off the shelf shock shouldn't be a problem for them to warranty. Failing that speak to your nearest fox service centre and send YT the bill.
  21. Sounds as though something isn't right, the ccdba has a slight notch you can feel in the first bit of the stroke as the negative spring equalises but it never makes a noise. Got another shock you can test it with? I guess speak to YT and get them to send a new one out
  22. Is it linked to equalising the negative air spring? I seem to recall that with the ccdba (same layout) you have to pressurise the shock, slowly compress it to set the negative spring and then adjust the pressure from there. That wouldn't necessarily explain the noise though, is there any discernable physical feedback when the noise occurs? Worthwhile talking to tf tuned to see if they have experienced it.
