IT had less than 10 hours on the bike from a novice rider. Like new. It was a dog , I had a kiehin so ordered a manifold for thw bgger carb. The vacuum i take was a joke. It just would no pull any fuel. That 2012 the frame was like spagehtti. The head stay from frame to engine, we would lose that bolt no matter what, I finally double nutted it and red loctite. Any how that vacuum system is someting to run from. I could go on but this post would be deleted. It does seem a little complex but I suppose less so than a 4RT with the capacitor & efi? People do seem to have trouble with fuelling on these, even with jets getting clogged despite filters + care. I'm actually really sorry it's going back but better that then stripping the carb, sourcing a replacement inlet manifold and maybe considering crank seals... So once I'm refunded I'm back on the bike hunt! Quote Link to comment Share on other sites More sharing options...
