Hello, I have a 1985 Sherpa T 350 that sometimes will not make spark. I have
taken the side case off and found some rust and that kind of white powder that
occurs on aluminum. I dont have a flywheel puller to gain full access to the
points and condenser. Is there a better set of points or dual points that would
fit this model? I noticed on the flywheel it says "FEMSA". Not sure what that
means. Appreciate your feedback and wonder if a flywheel puller is available.

..............................>>>>Hi Robb, I'm no expert,but can share some tips
that other Bul owners have said that I have used on mine to obtain good
spark.Along with the puller,a flywheel holder makes it easier to remove,and
torque down when you go to reinstall it.Make sure that the points are making
square contact,and use a points file to clean,then flush with spray-on contact
cleaner,and run a clean business card thru.I set the points to exactly .015,and
make sure that that the stator plate is grounded good.Maybe remove it and clean
good behind it,and it's a good idea to run a ground wire from that right up to
the coil under the tank,to be sure of a good ground.Mounting a Kohler or Mallory
condensor up under the tank,on the coil bracket is a good idea,as it gets it
away from the heat.Be sure to set the timing to the correct specs,for your
model.Do that by rotating the stator plate,not by adjusting the points gap.So
you will need to get or borrow a dial indicator to do that right.I made a TDC
reference mark on my inside case,and on the flywheel,and then a "F" mark at the
measured BTDC spec on the flywheel,so it can be checked in the future without
needing a dial indicater,just your ohms meter.If it's a bike you are going to
keep forever,and you want to stick with the points setup,then making a handy
tool by getting a good used flywheel of the same part number,then cutting
everything off except the center part that has the cam,makes setting the points
gap super easy,since you dont have to mess with working thru the window in the
flywheel,which for me,was a real pain!.Also,be sure the kill button isn't
causing the erratic spark problem,and be sure to check the spark plug boot
terminal to be sure that's good too.The coils are pretty reliable they
say,although on mine,I ended up needing new ones since the time I've owned it,so
it's possable to have problems there.A good shop manual is a good thng to get
when you order your puller and holder.We sure are lucky to have such good
Bultaco parts suppliers,it really makes it a breeze getting parts! Sorry for the
long post,but I hope some of these tips help! Take care, Steve Johnson
