Ah Jasus packie sorry to hear that ,and I was mad to buy that of ya awhile ago, still would have bought it with the knackerd engine though, pity,
Not too worry, Padraig...its only a bike. On the plus side, the big Bandit 12 is getting more use now and I had her out for a 250 mile spin today. It was like riding a Rolls Royce in comparison, to be honest. My B12 is seriously modified for comfort and for my tastes. I have a €600 gas assisted yankee rear shock with a 700lb spring, and I have modified the forks too for those potholes!!. I also have a custom made comfy seat with added foam and gel inserts for long distance touring which was made by Bagster, France. I also have one of the best cruise controls fitted for the long jaunts, along with fully adjustable handlebars with risers to suit my riding position.
Man...that motor just oozes in torque and the gearbox is super slick which sends a nice tingle up the spine every time you bump up a gear!! It kicks you instantly as low as 2,500rpm with a further noticeable kick at 4,000rpm and onwards....so its all on tap at the right revs for my style of touring type riding, which makes roll-on overtaking in top gear so effortless.
And thanks to Haynes and some Bandit forum guys which I stumbled on recently....they noticed that Mr. Suzuki was very heavy handed with their TPS adjustment and that it was set wrong, not alone subtly effecting the running of the bike, but substantially effecting fuel consumption. The adjustment on a Bandit TPS is done in a different style to the Fazer and not via one position on the rev counter. It is done with two readings off a voltometer and "maybe" allows you to adjust in a more precise fashion. It is determined by two readings....when the throttle is closed and when it is opened.
When you get your reading with the throttle closed (in my case 5.5omhs)...then you open the throttle fully an take the reading of that. It should be 76% of the throttle closed reading (above).... which would be 4.18omhs. Suzuki had this reading like about 60% and 4.5omhs, which in particular effected fuel consumption. So you open your PHILIPS screws on the TPS and adjust the TPS until its reads exactly 4.18omhs with the throttle opened...and easy one man adjustment when you have a cruise control to lock the throttle fully open!!.
With the Bandit forums guys new TPS adjustment, the bike is running slightly smoother with an increase in fuel consumption. When i'm riding about 70-80mph plus with a little venturing up to the 3 digit mark from time to time, I would be getting about 40mpg...now she's doing 47mpg which is a very acceptable return from the big 1.2ltr lump.
Ring yer man next week, Padraig...those carbs were running sweet on the bike and might sort yer little glitch out. He'd sell them cheap and he might even do a deal on an exchange for your carbs.
