  1. It seemed to be there but quietly. I put a Lextek exhaust on and suddenly it's really loud. 100% not leaking at headers or spring rattle though. I've watched a few videos on YouTube of people riding the bikes and there's no similar noises. I'm wondering if it's just insane intake grumble?
  2. I've also drained the oil, no sparkles, cut open the air filter, no flakes
  3. Another video, the last run at 4k rpm is the loudest
  4. Doesn't happen in neutral, but happens in gear with brake on
  5. Did them after valves, that was my first hope It sounds like a leaky header, but only happens under load, and comes and goes at very specific frequencies???
  6. Hi all, wondering if you can help being the experts n all. Got a b12, 2002, 20,000 miles and I'm getting a a really annoying knocking / rattling noise on acceleration. Initially I thought it was detonation due to fitting the ignitech, but it still happens when using standard CDI. Bike is pretty much standard except stage 3 dynojet, pods and exhaust. The noise isn't there at start or idle, or revving freely. It comes in initially about 2000rpm, then goes, then comes back about 2500-3000rpm, then goes, then comes back between 4-6000rpm albeit quieter, at these revs it sounds more like a grumble than a knocky rattle. It is apparent in all gears, comes and goes quiet to loud to quiet, extremely consistent with revs. It's not there when I pull the clutch in. It seems to get louder the further the throttle is opened, but disappears with clutch. Its really doing my head in, and seemed to get louder when I changed the headers, but I've tightened and checked for leaks and nothing. Please help!!
  7. Just found them from googling 3d ignition map. Had a few runs up the road today. This is so far the most responsive map, I've only been doing up to max revs in 3rd gear and trying to get the revs as close to idle when poodling around. Very smooth, very torquey and so far no nasty noises. Still doesn't behave amazingly well on choke, but comes off choke and idles fine after about 10 seconds. I took a bunch of columns out at higher revs as it created steps where as this creates a nice linear increase
  8. Nah I'm going to change it. Again was looking at turbo maps which are for lower compression motors. Stay tuned for v2
  9. Because I've been looking at spark maps for high compression engines with turbos, also because I'm a fucking idiot still, better safe than sorry. Should have been googling 'naturally aspirated' timing map, And probably ignored this website as it seems so insanely conservative http://www.useasydocs.com/theory/spktable.htm
  10. Ahh, 1 post further back. Stock ignitech TPS map has a huge hump in it around 10-20% throttle. If you just add 5deg to everything it gives a couple points around the mid 50s, hence I didn't like it and changed it
  11. I'm going to turn down the advance at 0-2% throttle. Seems to upset the choke a little bit as advancing too quick
  12. You might want to read my post again... Lol
  13. I've just copied what exists and adjusted based on reasonable guesswork. It's an improvement on the standard unit +5deg
  14. The stock ignitech maps are rubbish. I enabled TPS and it gives you a mental amount of advance between 2 and 10% then goes flat again, adding 5 degrees to this puts you at about 55' !!! It also gives a horrible surge if your coasting at low revs in a high gear. I've studied a ton of maps and used a generator also going from what I know is safe and made one that works pretty well. Dropped down to 30 degrees at full throttle and it absolutely rips with a ton of torque down low. Will post when I get to work in the morning. Anyway, what's this secret I missed? PM me
