YAMR1KRIS Posted August 2, 2016 Share Posted August 2, 2016 My R1 (2000 5JJ) as recently developed a fault causing a misfire at low Revs. When I have had it MOT'd it was Serviced, Oil filter and Plugs since then its been fine. But today took my bike for a quick spin and it feels like its misifring. up to about 4-5k if on main roads it runs like a dream just seems to do it round town. I have taken the tank off and the HT leads feel firmly in place, but I had noticed some petrol coming out the overflow by the side stand. I am good at fixing things just not at diagonising issues. Has anyone got any ideas as too what could be the issue. Thanks in Advance Link to comment Share on other sites More sharing options...

Moderator Airhead Posted August 2, 2016 Moderator Share Posted August 2, 2016 Ohh 15k isn't much, I was wondering if the emulsion tubes might be worn due to high mileage...perhaps not then Link to comment Share on other sites More sharing options...
anyoldiron Posted August 3, 2016 Share Posted August 3, 2016 l have a 99 R1, ive noticed they dont like low oct fuel or old plugs. Also, just because spark plugs are new dosent mean they are good, swap them out for another new set. and yes, i know what a PITA its is For what its worth the best thing i did to my R1 was fit a ''lvans jet kit'' and use his tuning specs i now have better idle, more torque lower down and the front wheel isnt quite so airbourne. l do not think it makes more power, but it most certainly makes the power you have more useable. Also the engine smells better after its been hammered, just a nice hot oil smell, before the was a hint of burnt in the smell. 1 Link to comment Share on other sites More sharing options...
