I have a set of BUB reverse megaphones that I'd like to put on my 907. Problem is they are for a 900SS. Is there an easy way (like using a 900ss crossover) to mount them? Ducati_900SS-cobbed.jpg [ 29.72 KiB | Viewed 5648 times ]

Apart from getting bent bits of stainless tube to fit ,how would they affect fueling ? I dunno much about injection, or 907 ,are they easy to adjust fueling on . They are cool looking pipes . I guess it depends how much money you want to throw at it ,but Id be inclined to do away with the cross over and go for two single pipes with a link pipe between them.

Already have a stage II Ferracci chip. Fueling wont be an issue. |

I got given my bike . We had to use loppers to cut all the ivy that had grown up thru the bike just to be able to move it . I have since bought another stock disc and a pair of f08 calipers and the spacer with the intention of going double disc . Probly should drag it outa the shed and give it a run but the battery has finally crapped out ( it be 15 years old , so not to bad ). It has all the dyna ignition bits and now wanting some PHF carbs , I have a spare pair of heads of a lemon ( ebay ) that I might port ...... sorta depends on what size carbs I find , and then some proper exhausts . The headers are stock but #ucked ( inner tubes collapsed ) crossover is home made as are the heat shields and the mufflers are Chinese copy nortons . It got it going at the time .There are a few other parts that don't belong too. |

Does it still have the chrome bores? They tend to flake off. Heads off of a lemon? LeMans heads are only useful with the matching pistons. In reality, there's not much difference between a lemans head and the T heads. I can give you my recipe for a sweet running 850 motor that will rev and make power to 7500 rpm and will have no issue going past 100mph on a budget. I also have a couple of Guzzi's with wilder (and more expensive) tuning. |

It has steel liners , and that was the issue . Some guy took it to the local rural garage for a rebuild and they #ucked it up , fitted liners and bored them to tight and it seized almost straight away , the guy packed a shitty and chucked in the shed ..... for 20 years . there was ,apparently a bit of agro with his brother who wanted it but the guy sold it to my bro in law for next to nothing rather than let his brother have it . So my bro in law chucked it in another shed .... yeah, the one with the ivy , and did nothing to it . I give him shit about letting a classic go the waste and he eventually got sick of me and one day gave it to my Mrs .... ergo it is now mine  . So I stripped it down and found LOTS of new bits . Cleaned all the crap out of the crankshaft , honed a bit more clearance into the bores , fitted a dyna cdi and coils , bigger alt , made my own wiring harness and fuse/ relay set up , fitted Yamamha XZ 550 switches ( looked about the right age ) GN 250 blinkers and a Yamaha AG 175 farmbike rear light and rack, new fork inserts and rear shocks , shimmed the gearbox and new bearings and painted it with spray cans .......oh yeah , new seals in the diff..... which still weeps . I scored a set of lemon pistons but they are a bit big so I havnt bothered . Sure would be keen the hear how to get it going a bit better . I suspect my VHB,s are a bit knackered ( I did put some new bits in them ) hence the eye out for PHF,s . Hamish |

My goal was to build a period sportbike that would have equaled or surpassed a V7sport or a LeMans. These mods happened over a decade. #1 36 Del'ortos with the lip of the intake port smoothed out to get rid of the step. Meh, not much really. Bigger carbs are a waste by themselves. #2 Norris S/ Megacycle X9 camshaft. That made a noticeable difference. more midrange and revs higher. better. The heads were a bit tired and I had to pull them to install gilardoni cylinders and pistons. While off it was time to tweak them. #3 full head porting /shaping with stainless valves. the squish was set to .040 with thinner copper head and base gaskets. That really woke thinks up. #4 Added Lemans flywheel with mild lightening. I have a couple of other guzzi's with crazy light flywheels. I wanted some flywheel effect for this one. #5 Mistral headpipe and crossover. ( didn't do much. I already had open conti replica mufflers on the old exhaust.) What made a lemans hustle was the high compression pistons. The rest of the engine is pretty standard. The cylinder heads are not all that different. I have one head and did a comparison. exhaust valves are 1 mm larger. intakes are 3mm. The intake ports on both heads are about the same size! I have a LeMans engine with new pistons and cylinders that I thought about installing and decided it wouldn't be worth the hassle. |

here is another Guzzi of mine. The local dealer retired in 1997 and in 2015 he sold me / had me clear out his guzzi stuff and junk including his racebike which needed put back together. |
