Hi Guys, Just joined the site, great forum and great site. Hopefully some one out there with loads more commando experience may be able to help me.
Recently got my first Commando.............850MK3 She looks great, in need of a little TLC but pretty good. However,i have a problem with her that one of you guys maybe able to help me with.When i got the bike i noticed that it started easily but i couldn't get it to tickover it seemed to run ok upto about 4000 rpm but then didn't want to rev any more, even in 2nd gear, seemed really laboured. The bike still had the original black airbox, the carbs were jetted to original spec, but had peashooters fitted.I checked the carbs and they were Knackered, I decided to replace the carbs and fit an earlier type airfilter in the hope all problems would be cured. Les Emery at Norvil jetted them for me. I fitted them and sync'd them. She now starts, 1st or second kick and ticks over fine when warm.She rides ok up to about 4000 but still won't rev freely when you try open her up, the engine "deepens " but not a lot happens, I get no popping or banging or anything else, she just doesn't seem to have any power. Timing has been strobed and is fine, jets and needle position have been adjusted and changed, I've fitted new wires from the Boyer pick up to the control box , new plugs but all to no avail. Would appreciate any help at all.
