Success ! .... Finally. Larry has been running me through a problem solving process. A challeng for Larry with my knowledge. My recent red 350 Sherpa had arrived part through and proved a good reference. The thing that threw me was the new looking mikuni carb. Having no history on the bike made it difficult. Having run threw cleaning the carb, condensed etc. We focused on the carb. It wouldn't run on the other bull. Couldn't ID the jets and the slide was strangely scratched and scored so in a desperate move I ordered a new Mukuni from Bultaco uk. 5 mins to fit and we're off power all through the Rev range. Starts first or second kick from cold

Popped an new plug, got it started but power symptoms persist and it certainly needs that plug there more to the problem that this. Larry is kindly running me through an idiots guide via email to fault finding, afraid I'm the idiot ! I get a timing a tool, feelers gauge and flywheel pulley and persist a bit longer before I kick it and take to the shop... I might just learn something. Will update you on the faults in a few days. Thank you all for you support. Mark

Bondy What's a head steady? I see a bracket on the head. M

Had a close look at my tank tonight in a strip down attempt to get it started. It appears to be alloy... Muppet I am. Side panels are fibre glass or plastic. Correct? There is a picture of it on the starting problems thread.

Hi Just got the last additional posts thanks you. I think I'll get a new plug tomorrow. I've cleaned it and gapped but looks well worn. Carb I'll look into that. Can't get the bloody thing started at the moment and my leg is dropping off. There is a spark but it looks weak to me. Points look clean but electronic ignition seems a good thought... How much ? Still I polished the tank in defeat off starting, bike it looks pretty good even if it doesn't work

Well tried all that in so much as my skills allow, blood still spurting from my hands ! Recommendations for a pro shop near Newark upon Trent ? M

Hi, Premium... Not sure now. I like the general look at the eBay imported one but yes that frame looks redone. Thing is engine doesn't look great and believe stood for a while. At 3k think I need better and sorted.

Thanks... Yes Carb and jet look clean. No aide leaks. I'll check points and see if I clean without pulling flywheel as I don't have a puller. Timing need to see how to do this? M

Hi Looking for a little help, pointers and/or where to start. I'm no and#39;mechanic god' so assume nothing. I bought a 199A sherpa off eBay. Its not been run regularly but it has had quite a bit work done and looks generally tidy. Bit of a risk as bought it unseen. Got delivered home, filled up with fuel/oil mix and my excitement I managed to start it after several go's. Choke doesn't seem to do much, fiddled on and off. Eventually fired with wide open throttle. Went for a ride and whilst it tick overs quite sweetly seem low on power and does free rev. Can pull a wheelie in any gear for example. Had another go today. cleaned carb out but nothing in there all clean... looks very new its a Mikuni carb. Went for a ride same symptoms and eventually getting it started again wide open throttle was the only setting to get it going. Again ticked over nicely but not sharp revving. After 5 mins stopped on me. May have left fuel off. Cant get started again ! Gave up ! So in summary: Low power / revving but good tick over and plenty of torque low down revs. Terrible to start... killer on the leg and lungs ! Compression good ! I checked for spark, get one not sure if strong but there is one. Bike obviously not used much been in storage a while I think. ... Where should I start? Need this thing to reasonably reliable. Not called the local motorcycle shop jut yet. Ideas, pointers very appreciated. mark

Hi There is very helpful in understanding. I currently have a blue 199A which has a plastic tank. No idea of the history. It's had the frame colour changed from white to blue. White mudguards. So in guessing that must have been changed. I have just bought a red 199A which has come with alloy tank and white plastic mudguards. I particularly like look of the alloy mudguards. The one your referenced actually is a plastic tank as its a USA import, I called them today. Hence my confusion. It seems an alloy tank carries premium ? Why? My plan is try for originality but the one in eBay is pretty much a perfect look... Other than som me work on that engine and some general polishing.

Hi I've have a 350 Sherpa which has a plastic tank 1979/80 model. Im look for another Sherpa 350 but I'm trying to get an original spec. Which Sherpa models/date had alloy tanks fitted as original and alloy mudguards ? Or were there optional extras etc. ... I particular like the look. My plan is to restore one to look good and one to use. Many thanks Mark
