July 15, 20215 yr Hi all! I've searched for hours and didn´t get to a point, that's why I'm bothering you asking for help. I have s Sherpa T 250 model 190 (1977 I supose). It is matching numbers but my "problem" is that these numbers are 8 digits instead of 9 digits (RM-190***90 / RB-190***90). I've checked a serial at the left crankcase that is 112-10Y019, what I think confirms that is a 250cc Sherpa/Alpina engine. Does anyone know why it has these 8 digits if it is supposed to have 9??? Thanks in advance for any response.
July 15, 20215 yr Hi - 8 digit model/serial number is correct - who says it should have 9 ? 112-10Y019 is merely a casting/mould number and means little beyond as a means of identifying a basic crankcase casting. I think 9th. digit would be a suffix letter "A" or "B" on later variants of models 198/199 only (but I'm sure someone will correct me if I'm wrong). HTH Edited July 17, 20215 yr by lorenzo clarity
July 16, 20215 yr Author Thanks for your answer lorenzo, I thought it had to be a 9 digit serial because I saw the 66’ lobito series were 8 digit starting with 19 Edited July 16, 20215 yr by Crockett
July 17, 20215 yr Can't really comment on very early Bultaco numbering, but it makes sense to me that Lobito model 19 would have a 7-digit serial, in common with most (all ?) models up to at least model 99. I have units of models 80, 85, 92 - all have 7-digit serial no. Can't say at what point Bultaco went to 8-digit........logic says model 100 onwards, (to distinguish from 4-spd. Sherpa mod. 10), .......but I had a model 100 Pursang 125, still with a 7-digit serial ....... Maybe someone out there has the definitive answer ? Edited July 17, 20215 yr by lorenzo
