  1. Taking the bus or going actually on the bike?
  2. Well they let me book the Friday off so will run up then.
  3. Fuses dont save this kind of cock up, quarter of an amp will kill an ecu if its in the wrong place, could have fried every battery fed electronic device on the bike.
  4. That may well have been a very expensive mistake, electrics are quite often polarity sensitive. I made the same mistake on our caravan and had to replace the tv and the electrical circuit board in the fridge. Five hundred quidsworth for the sake of not checking.
  5. As a 2 stroke man john you should ride a propperly sorted vmax, crazy. Needs to be a good one though, lot more posers than do ers out there.
  6. You have gone from peak torque/peak revs to peak torque no revs. You need to watch the taco for a bit, revving a v twin hard will just send your fingers numb. Peak power is around 8 and peak torque around 7k rpm so in theory your sweet spot for gear changing will be around 7 to 8k. Your ears will argue with you because they are used to 20 valves and 4 pistons rattling around (figuratively they do make noise). Now you have 8 valves and 2 pistons so half the noise and exhaust note. Your head will be telling you to change at ? probably 16k. Not being sarky your waiting for the normal resonance of the ace at maybe 8 or 9k if your pushing. Dont worry about big handfuls of low rpm throttle either its where a v twin thrives, from as low as 3 k wang the throttle open and she will drive, the chunder ace would likely bog till it gets its stride. Short answer you need to turn your riding upside down, low rpm drive is the key. Your all finished and ready to have a cuppa before the ace would be getting on the cam properly. And, i have seen it first hand, those v twin suzuki's are a looooong way from slow, once you sus the riding style you will rip the commute apart.
  7. Ugly mess to sort out. Dont know a great deal about these little bikes myself. Deliberately bought a carb'd bike for my daughter because i knew how to fix it. I know that doesent help your situation, i recall hearing that the Fi bikes have different cam timing and compression ratio's to get the best from the precise nature of the Fi so you could well be flogging a dead horse. Your safest and most guaranteed option would be to pick up a cat c or similar that you can tear apart for the engine and knowing you will have all the aux parts you need. Would love to tell you more but don't know, Fi is a blackhole i have never bothered with.
  8. Fowlers of bristol, their website has all sorts of technical drawings and parts lists.
  9. I will tag along Andy, might get one or two to come up with me. Prob best to keep it informal.

    Breaking fj1200

    Time Left: 11 days and 22 hours

    • FOR SALE
    • USED

    Fj1200, 91, non abs, bodywork in really good condition for age except the normal missing lugs on the front muddy, tank is solid, actually have complete bike in bits. Have v5. Immaculate neta exhaust. Came with a vmax in similar state but have neither the space nor the inclination to do anything with the fj. Want it gone, make me an offer.

    300.00 GBP

  11. Yep, sounds like perm choke. May not need full choke in the summer but should always need a little from stone cold.
  12. Providing i can get the time off due to the now critical hgv driver shortage, im up for it, bike is far better this year too. Keilder is a trek, looking at 5hrs min if i go the straightest fastest route stopping for nothing but fuel.
  13. Was there anything showing on the plugs, excessively wet or black. Ig is easier to check than carbs but ultimately it sounds like you need to give the carbs a good clean. Your coming off choke at a mile or so as the engine gets up to temp and as she wants a leaner mixture it sounds like she isnt getting it and chokes out.

    It's got ypvs in dirty great letters on a fitting on the right hand side of the engine. If you have a learner legal (haha) model it may just have what looks like a bolt sticking out of the rhs of the barrel. Either way Google mk1 and mk 3 rd125lc. The mk3 had ypvs, the mk1 didn't. Look at the barrels on the engine. The difference is obvious.
  15. I cannot find tx500 stuff, but its apparently pretty much early xs500 so i was looking at the 75 xs500 which looks to have the same kickstart mech as most yams running on the clutch basket ring gear. Cannot find anything to confirm that though, could be a longer shaft running on one of the gearbox idlers maybe but that seems a lot of hassle The starter motor runs a chain to a starter clutch that turns the crank, looks identical to my vmax. Spent far too long wondering about it now.
