January 14, 201313 yr Got the above,anyone ever have to retard one or am i getting too old. It's not the initial pick up which is quite perky,but mid range is instant. Cheers.
January 14, 201313 yr I thought if anyone knew about Retards it would be you. Sorry cant be of any help though .
January 14, 201313 yr You could Richen the needle as well. If the jetting is spot on now, richer will slow down the pickup a bit.
January 14, 201313 yr Author At least laser has a constructive suggestion,the rest of you wouldn't know a trials bike if it run you over. I would be reluctant to touch carb settings as it runs so nicely. I was hoping someone had retarded (Good word in this company)one,and how it went. No more replies from Jockland please.
January 14, 201313 yr I'm not being funny but have you run it past Birkett's . He might have a solution for you I've phoned him on a couple of occasions and was really helpful.
January 14, 201313 yr Birkett's set my bike up from new to be soft, they knocked the timing back. http://www.shercousa.com/pdfs/sherco_ignition_timing_guide.pdf
January 15, 201313 yr If it's the auld sherco engine, pull the flywheel off, mark where the stator is, slacken the 3 bolts, then move the stator plate about 5mm, rebuild and try it out. It made a difference to my 04, 06, and 09 bikes.
January 16, 201313 yr Oh it's the Sherco motor then! Yep, Demmo is right. There should be a mark on the stator plate that aligns with the right edge of the casting web on top. I usually tell folks , a change(counter rotation to retard or slow) of 1-2mm(mild), 3-4mm(mid) or 5-6mm(most), so adjust accordingly. Seems a 1mm change is not really enough to tell.
February 11, 201313 yr If you are wanting to slow it down a bit, you might put a slow turn throttle on it, that is if you have a fast one on there now. The white tubes are the fast one and the black are slow.
