Wolf Classic 150 / Re: Wolf Classic EFI problems starting
« on: February 07, 2021, 11:43:06 AM »
 As far as I know, the Classic 150 has a carburetor.  Unless you are in Taiwan, or possibly Europe, the have carburetors.
 Oh, checked your profile and you ARE.
 If you mean 'push button start', not working reliably, then I would check the battery state of charge.  A '12v battery' will actually be closer to 13v when charged fully. Each cell produces 2.1V, so a six cell battery fully charged should be ~12.6v.  You can also check battery voltage with the engine running, and it should be over 13v, most charging systems running in the 14v range, possibly up to 14.6v.  Over that is a bit too much, and will cook the battery, and possibly boil off the electrolyte.
 Auto batteries will maintain over or close to 10V even when the starter motor load is present, as in while cranking the engine.
 You may not have enough voltage to run the EFI system, causing the CEL warning.  Low or below threshold voltage will likely cause a CEL to be lit.

Hey Mister!!
 I realize this is an oldish thread, but interests me so here goes.

 Did you ever get on the road?  Do you have a pic of the finished product?  How did it work out in comparison to the original?  What sprockets did you use - factory or different?

Maybe here:

 They show the parts at least.   Cam Purvis at may have access
to other Sym parts.

 Use a flat-blade screwdriver and unscrew the drain at the bottom of the carburetor float bowl a couple turns.  If there is fuel in the bowl, it will drain out the tube attached to the float bowl onto the ground.  If fuel is lacking you won't get any to fall onto the ground.  The vacuum operated petcock could be failing and starving the carb & engine of fuel.
 Other than that, get a spare spark plug, disconnect the plug wire, jam the spare into the plug wire socket, crank the engine and watch for spark.  The shell/body of the plug should be resting on the engine fins for ground, or you won't get spark at all.

Wolf Classic 150 / Re: Dim headlights
« on: October 21, 2020, 08:47:36 AM »
 I do not ride at night for the most part, so don't know how bright or dim the factory headlight bulbs are in general.  But, there are multiple LED options available that use less current to generate even more light.  I think.  But, again, the LED must be constructed so that its output is at the center of the reflector.  Just stuffing a bazillion LEDs into a 'bulb' doesn't do much good, except to light up the clouds, cows, and everything along side the road, while maybe lighting what is ahead.  It must be focused properly or all is wasted.
 If you look at the bulb assembly, you should be able to discern that it is 'keyed' so that it fits into the reflector only one way.  Any LED to replace that should also be keyed to insure the light developed is going to be reflected properly.
 You do not want to overdraw the circuit as it could blow a fuse or melt the insulation, and you would need room inside the headlight for the LED socket if you went that way.  Perhaps additional lighting, external to the factory, would be a better solution.  Look for auxiliary driving lights or headlights.  There are many on the market, and there are models that can be mounted to the handlebars.
 A CSC RX3 rider on the CSC group on facebook living in TX recently posted about his added lights that he was very pleased with.

Wolf Classic 150 / Re: rear sprocket source
« on: October 21, 2020, 08:30:01 AM »
 I think I would contact them to verify their pricing.  Somehow I got the impression that their custom work was not so high.  I don't know sprocket terminology so could not tell what was/was not needed to make a usable sprocket.  IOW, I had/have no idea what 'features' are required and which are optional.  That's why I suggest emailing them with a query to see if you have checked all the right boxes, or could skip a few.  I kinda sorta don't want to learn that stuff right now...

Did you go here:

 I did not fill it out, but for the indicated cost, seems very attractive.
You do need to provide specifics on center hole, bolt hole position & diameter, thickness and number of teeth(and size...)

 Most bikes from the FE have either 8mm or 10mm thread mounting holes for the mirrors.  You can source from daBay or daRiver and get something you like.  The mirrors on the end of the handlebar are nice if you have a problem seeing who/what is behind you using the standard mirrors.  Again a local shop or the above two are reasonable sources.
 I would get a cover as it will slow down the casual jerk who is jealous that someone has a nice machine and they have been deprived of same.  A cover will also make hopping on in the AM a nicer experience as your incidence of wet butt will decrease due to the dew being on the cover instead of the seat.  Even a tarp from HF helps keep things dry, and will help to protect the plastics from UV damage(I think) and keep the seat vinyl from aging as quickly.
 I bought an el-cheapo disk brake lock from aliexpress.  It will not stop anyone determined to swipe your bike, but will slow down the goofs that will steal/re-position/move your bike 'just to be jerks'.  It is harder to move when the front wheel is at an angle(locked) and the wheel cannot rotate(rotor lock).  It does take conscientious effort to put the cover on and to remember to put the lock in the rotor.
 I knew a MelissaAC at PU back in the day, a PiPhi.

Luna, a trick that may help to remove the old grips is to use compressed air.  Get a air nozzle that spits compressed air in a small area, generally used to blow off parts, or clean shavings, etc.  Direct it towards the close end of the grip, so the air can get inside the grip.  It will tend to 'blow up' or expand the grip, or at least break it loose from the handlebar.  With the air flowing, direct it around the sides, top and bottom to insure the grip has at least moved, then attempt to slide the grip off the handlebar.  You may find a youtube example of doing this task.

 I am not much above sea level, but have not pulled the plug recently to check if I need to richen up a bit.
 What makes you think it is a bit lean?  Temperature?  Noise?  Spark plug looks 'bone white' with NO color?  Melted electrode(center or side)?
 Peer down the center, and look at the center ceramic insulator.  It should have a 'ring' of color per the 'experts' that indicates how rich/lean it is running.  The further down, the richer, as I understand.  Guys talk about a 'spark plug chop' where they run hard, cut power, coast to a stop, pull the plug and inspect.  I think they use a new plug, FWIW.  It should show how it is currently running via the circle on the center insulator.  So they say.  I have not tried.
You could raise the needle in the slide, I think, though have not tried.  That would set the mixture a step richer across the board in the mid to high range, but the main jet limits more at the higher end.
 I expect somewhere someone has gotten a 'performance' carb on one of these bombas, and has added 10% hp/torque and raised the top end a dozen mph.  Maybe.  I think the exhaust doesn't need a thing, and the emissions 'stuff' doesn't hurt anything, so all that's left is a bigger/perf carb.  I think.

 Did you remove the idle needle adjusting screw?  It can have some 'stuff' at its needle end, the pointy part that pokes into the venturi, that can block flow.  The port to the venturi could be partially plugged.
 Did you pull the pilot jet out completly?  It has holes drilled across the 'tube' portion, forming an emulsion tube where the liquid fuel and incoming air get acquainted and start to 'foam', forming an 'emulsion'.  Bubbles of air get entrapped and carried on to the gizzards of the engine.  If the emulsion tube is plugged, the idle will not be very stable.  If the flow from the tube to the venturi is clogged or has a bit of blockage, again, poor idle.  Make sure you didn't soak the oiled air filter element.  Press between some paper towels to absorb any excess.  You want it wetted, but not soaked, and not 'drooling' any oil.  Smush it a few times, re-fold the paper towel, and repeat.  It doesn't need but a few drops distributed, and pressing will do some of that distributing.
 I found that a plugged pilot will make the engine jump up to a couple k rpms with just a close look at the throttle grip.  No need to even turn it. Makes for CRAZY riding when the engine zooms at a whiff of throttle motion, and then sometimes just takes off rpm-wise on its own.  Clean the pilot, the bowl, and the main jet, make sure the slide moves freely, and returns to closed/idle position without hesitation as you put it together.  If you didn't remove the idle mixture screw, you'll have to get a pick or a tool to dig out the plastic goo so you can fiddle, IF you think the mix is off once you are done.  If you are at high altitiude, it will likely be running a bit rich at idle, and perhaps on the main jet also.

Just re-read your description.  I think you are not running on the pilot jet nor the idle circuit yet.  I tried to describe a wild idle that I had when the pilot was gunked.  It was adjusted, the throttle, to get it to run, but it was very unstable.  It was because the throttle plate was just at the low edge of the middle speed circuit, which was not able to keep the engine running at idle rpm, and jumped to high rpms all by itself.  That was a plugged pilot, and a mal-adjusted throttle idle setting in an attempt to compensate.  Get the pilot out, poke with a 'hair' from a wire brush.  They are stiff enough to poke through new 'gasoline' goo that has aged and set.  If you cannot see light through the pilot, it is still plugged.,  You should be able to run a brush 'hair' through from either end, with a little fiddling to get the wire to line up with the center of the orifice.

Wolf Classic 150 / Re: trouble hitting neutral
« on: September 14, 2020, 09:29:18 PM »
Ride some more.  Get the bits worn into each other so the clearances open up a bit.  A rotary shifter has a pin that followes a groove in a 'drum'.  The pin is moved by the wiggles of the groove that push the shift forks back and forth to disengage one, and engage another 'dog clutch' with slots in the side of the already-turning gears.
 I have problems also, but niggle it back and forth 'til I find it, then release a bit of clutch, NOT the whole thing, to insure it really is in neutral.
 Having the chain tightened properly seems to help as it puts more consistent 'downshift' pressure on the engaged gear, I think.  I do know that a loose chain makes shifting harder, and finding neutral harder also.

Make one yourself.  If you have access to a hunk of wood, a drill, a Bernz-o-Matic torch, and some lead, you can cast your own end piece.  See on youtube, sixtyfiveford channel for explanatory example.
 You can purchase cable 'inners' of a length you like, or an emergency cable from 'zon or 'bay that will get the job done.  I have come to the conclusion that cables are not as exotic to make as they seem.  Watch a few tubes on them, and give it a whack.  What do you have to lose?  Time.  But life is all about time(among other things) and knowing your bike, how it's made, and especially how to fix it when 'things' happen alongside that road somewhere west of Laramie is what adds to the spice and zest that gets you up for that first cup in the AM.
 Make one.  You will be proud, and can relate the story to the rest of us schlubs...

drumrolf... he made the decal logo, and had someone turn it into a decal.  I asked, and he tried to send me the info, but I never got it.  If you read back the thread, I noted somewhere that it reminded me of the Norton logo of the late 1960's, and the reply was that it WAS a sort of homage to Norton.
 I should have pursued the info on the decal making process, but didn't.  Maybe Ox will post...
