Hello, I just rebuilt a R75/5 from the ground up and added the Siebenrock piston/cyl kit that supposedly is a 20% increase in power. + Lightened flywheel. My R75/5 carbs were a bit too worn and the choke was leaking a bit and i couldn't get a good idle. I got a set of Very good condition 32mm carbs that were from a R80GS. I took them apart and cleaned just a wee bit of crud out. While they are apart, I'm wondering if I should leave the jetting and needle positions the same? Or should I put the R75 idle/needle/main's in the new carbs? The bike will supposedly be close to a R90 in power due to the piston kit but I'm not sure how the jets will effect or help/hurt the bike. Ultimately, i want something reliable. Does anybody have the Bing guide for jetting? Thanks in advance.
