  1. Yes that's correct. It will find it's way into that position in use regardless of where you set it.
  2. Striaght cut gears are more efficient, but not necessarily stronger, in fact the opposite can be true. Helical gears are quieter an make a bike feel more refined.
  3. A 180 rear tyre does look fucking cool on a slabbie though.
  4. Yes, but you'll need to remove the selector shaft, which means the clutch and primary need to come off.
  5. Have you considered wearing your under pants on the outside of your leathers?
  6. The Curved L,M 750 and F,G,H oil coolers are all 15-20mm shorter than the J,K oil coolers, so you'll need to make some adaptor brackets to fit them.
  7. I didn't realise till I tried the same. You could end up with the valve springs going coil bound. Didn't check if the Bandit and Dot head springs are different.
  8. That's for abike that has water cooling too. You'll need a bigger cooler than that
  9. I think You've miss understood the speil. They are only 1mm and 1.5mm oversize so yo can cut the standard valve seats to size rather than fitting bigger seat inserts. Not that there's room on a oil cooled engine but you might on others.
  10. I wouldn't go too far. Ted M measured his C.R at 10.9:1. I wouldn't go much more on an oil cooled road bike engine. When can I pick up the carbs.
  11. I'd still stick with the Bandit head. If you want midrange torque, you've bought the wrong carbs. Coz I like you I'll give you £350 for them. Seriously, with the Wiseco pistons stick with the Bandit head.
  12. Base gasket is the least suitable way, as you increase the squish gap, tighter the squish the more compression you can get away with. I've got a dot head, that I've just fitted to a stock bandit bottom end, I've opened up the combustion chamber a little around the valves, as the valves in the dot head are quite heavily shrouded, so there are gains to be had by in shrouding the valves with the bigger bandit bore, this will have drop the compression a tad, I regained most of that by skimming 0.5 mm of the head, but you wouldn't need to the skimming. Even opening out the combustion chambers you would still need to drop it more, I would look at machining the very top of the piston, and probably the valve pockets too, to get the desired compression, and valve to piston clearance. If this sounds like a lot of work, it is. You'd be better off fettling the Bandit head, and fitting the dot head cams.
  13. 750 rev to 12500rpm. Sounds like you need to get the bike on a Dyno.
  14. 4-2-1 will have more mid range as has been said. The down side is a slight loss of top end power. The length of the secondries is a really powerful factor. The spliner in the collector shown above won't do a lot. General rule the longer the secondries the lower down the rpm it will help torque. 6-14" are typical lengths. I've seen 20bhp gains over 2500rpm in the mod range vs 4bhp loss at peak on 4cyl car race engines. Between 4-2-1 and 4-1. Given a choice I'd go 4-2-1 every time.
  15. You can just swap the bandit and dot head cam sprockets over if you go down the dot head route.
  16. The bell crank or dog bones won't make any difference to the issue you have.
  17. It's got a bolt on subframe, so 100% a water boiler. Probably an 1100 frame.
  18. I was looking at those, rider must of had big feet. Looks like a well sorted bike. Good luck with it.
  19. It's definitely a water boiler frame, that's all I know.
  20. That shock/swingarm combo just isn't going to work guys, no matter what you do.
  21. There's another little bracket between fairing stay and fairing below thee head light. One bolt into the stay, 2 bolts to the fairing.

    That's a bummer on the 675 rear wheel, I thought it looked simpler when I had a quick measure up of a set. Not a fan of those eccentric JMC arms. Had one for my Slingshot, but sold as I didn't think the eccentric set-up was robust enough for serious track work.
  23. I don't think you can spend that much on the whole ignitech range. The unit I bought was about £80, though I get a disount as I've bought a few, even the basic version has more functionality than the dyna2000. The dyna 2000 is self contained through, where as the ignitech uses the stock ignition pick ups and you need a lap top to adjust it.
  24. Just receved mine Can we get some T-shirts too? Happy to pay.
