Hey guys, Well, the Giannelli pipe is fitted, and yesterday i put some lighter rollers in. I took it for a spin, and the whole setup works great. The only thing is that the engine makes a foo noise occasionally when going flat out....(ie at top speed.... during acceleration everything is fine...) Just wondering if anyone knows what this is. Ive got the modified airbox on, a 21mm carb with a 78 jet in it.
gap should be good... i regap everytime the plug comes out.... gap is around 0.55mm might be rich.... at least its not lean.... thats what i was initially worried about. it only makes the noise when im going flat out ie 75-80km/h (48-50mph) and it does it every few seconds...... ie brrrrrrrr foo brrrrrr foo foo brrrrrrr.... etc... (brrrr = normal engine running....and yes... i may be insane).... it doesnt detract from performance at all...its just a noise at the moment.
like, the sound a cold pidgion would make.. ignor hijm... sounds like its riching out a bit, mabey play with reed material thickness and have another mess with the rollers and jets.
