Sounds good. But send to Germany/Berlin would be expensive and lot of tax. The same at Bultaco UK, where it is sold out...

Hi guys, after five Sherpa and Alpina finally got a 76 Frontera 370 model 181. it runs not very good at low normal revs, a little bit fat, as nd at 3500 or 4000 it starts wheeling, full power...original bing 36mm is fitted. Does it make sense to go with Dellorto to get it more smooth? Any experience? On my Sherpas dellorto 26 and 28 working well...

Hi Johnjsy, i have c3 bearings in another Alpina I restored one year ago and use as daily driver. there is some up and down movement at the crank (very little) thats normal at C3 ?

Has anybody an Idea how this could happen?

I have both bikes and would say, they are very different. the 348 is better in tight sections. wheel base is shorter and engine seems to behave more directly .little bit more lichter and nervous than bultaco. wonderful to ride in classic trials . But i personally prefer the bultaco, which has more torque and character. its very good at hillclimbing and on rocks. and reliably brings you on the top of mountain. anyway not so easy in tight sections. it always demands a special style of riding...

Hi Mate, I am nearly 100 percent sure, that there is no difference between cranks wit two or three bearings. I found them in several sherpa and alpine engines. The difference is the seal holder. on the picture left side for one bearing, the right one for two bearings drive side. there also exist different seal sleeves. a long and a short one...greets

thanks for advice, will try this without spring and chain to have more space.the squeeze is located 5cm from end where the shaft is thin. hope its less work than splitting engine...

yesterday fixed ignition at my 199a . I removed kickstarter and case. started engine without left case, to watch rotating flywheel with marks on it and use a flash gun. (never had a problem with that) several times kicked back. I have a new cylinder on it,so it really has compression... Then with right ignition try to assemble case, but kick start shaft was very hard to move and didn't come back. Without screws in the case kickstart shaft could be moved but you could see it was eccentric . I tried to bent it back a little, with heat. no way and didn't want to break the engine housing. I never thought this could happen. bent shaft? ...any ideas?

...after two days riding without problems ignotion broke down again. We checked ht coil and there was no blank steel connection. the frame was painted new and somebody didnt want to destroy the new paint... unfortunately the green wire was also fixed to that point. (no real earth) Now the primary coil was killed...in the end the whole thing was a bad earthing fault. greets dr.alpina

Hi Mitty, may be you ask someone in the bultaco forum... greets dr.alpina

It was the condenser, thanks for your help folks. Bike runs unlimited now... We are looking forward to a nice season with four running Bultos this year

Hi folks : It really was the condenser. Bike runs unlimited now, tested out today... Thanks for your help.

thanks for advice. i will check that at the weekend . here is the plug...ngk 5

yes, that is what we thought first...but if you pull off the fuel line there comes a lot of petrol...i will check out that capacitor thing

Hi there, we have a problem since last week we put a second Sherpa 183 back into life . Engine is totally rebuilt incl. new piston, crank etc. Ignition is the old femsa. new points fitted. new carb. clean filters...When you ride, after one hour, the engine suddenly stops. We have ignition spark, but bike wouldn't start again. If you change ignition plug, it starts again but runs only 30 minutes, then the same procedure, but bike doesn't start with new changed ignition plug, although we have good blue spark...do we have to live with an 1,30 hour riding bike? any ideas?
