Guest rosso mandello Posted March 30, 2008 Share Posted March 30, 2008 After this winters effords, 11:1 pistons fra FBF and a port job and a lot of fiddling around to compensate for MOTO GUZZIS lack of detail, all done by an local racing expert, , on top of all my other modifications, I finally got what I wanted. 1 gear, just rolling, no fiddling with the clutch, just a twist on the trottle an of we went with the front wheel well over the ground . I may get old, but I will never grow up Summer is finally here Link to comment Share on other sites More sharing options...
Dimitris Posted March 30, 2008 Share Posted March 30, 2008 Excellent! What crossover and mufflers do you use? Stock or aftermarket? Have you dynoed your bike before and after the pisotn installation? Did you only change the pistons or also other parts of the cylinder? Link to comment Share on other sites More sharing options...

Have you dynoed your bike before and after the pisotn installation? Did you only change the pistons or also other parts of the cylinder? Modified AGOSTINI crossover, new AGOSTINI stainless mufflers, K&N open and all traditional aftermarked mods. The techicalities I am not into, but I understand that there was taken about 1 mm from each cylinder to make an "squis" band, also the heads were not exactly (0.00 mm measure) the same hight, I ended up with around 12:1 compression, but the gas is good here in DK (and the starter can also turn it around, which we were not certain of). No dyno yet, but I can feel the changes, so why dyno it to get in a bad mood (see the actual post more power please) mogens. Link to comment Share on other sites More sharing options...

jcbooghs Posted March 31, 2008 Share Posted March 31, 2008 12:1 is a lot for a pushrod operated aircooled 2valve twin! My dealer didn't want to go any higher then 11:1, a question of reliability. And reliable it is as I have already over 100.000 km I hope you also changed the original rods for Carillo's! These mods turn your Gooze into a beast, don't they! Have fun and... we want pics of those wheelies Link to comment Share on other sites More sharing options...

You've got one of Roper's sloppage sheets installed to keep your oil pickup from getting exposed, I hope? Link to comment Share on other sites More sharing options...
