I remember back in the 80s the thieves got really professional ; at first they would just grind the milling marks off and restamp another number on to the smooth surface . But a few of the younger policemen who were in to their bikes knew what had been done ; so then the thief's started making mock ups with the milling marks in aluminium ; restamp then glue on to the casing

Had heard about it but never seen it till then. Also had one that the last bit of the serial number had been ground off, new lines cut in and the last 4 digits re stamped. Looked really good, only noticed when you put a steel rule along the number and see the dip at those numbers. Steve |

.... Looks like that has been done with a worn Stanley wood butchers screwdriver ! I have a set of 350 barrels with the "347cc" removed. I always wondered if it was done by a racer in a 250 cc class ? or a youth, in the days when you could still drive a 250 on L plates ? It was obviousely done by someone who did not know about the 4L1/4L0 thing, as you can see, they have left the 4L0 still in place. :-) steven.  |

As above but with the RD250 air cooled ; the thieves would go out and steel an air cooled 350 and put the barrels on their 250 ; but back in the day they weren't as knowledgeable about jetting and oil pumps so would not change the carbs or pump ;needless to say they all either seized or blew a hole in a piston |

More than likely a learner back in the days when you could ride a 250 on L plates. Lets face it Plod would not have known the difference between 4L0 and 4L1 unless they had one. Would they have put all the effort into proving what it was unless someone had been hurt. I got pulled loads of times on my 250 and they never checked anything other than the L plates and the tyres.

In Aus there was cheap rego for 250s for years, so plenty had a cc adjustment. I see that as part of the 80s culture and have preserved it on my resto, here is a post from elsewhere I did when I restored my cyls: ----- The final job was to dig through my boxes and find the 2’s I had created ages back to complete the engine size on the sides of the cylinders:   Full story on why I needed the 2’s is here (almost at bottom of page): www.rzrd500.com/phpBB3/viewtopic.php?f=5&t=12311&start=75These were glued on with JB weld and left to cure. Ive found that JB weld is a funny thing, its quite dependant on weather and to achieve a full cure (so the rubberyness is gone and its sandable) can take a couple of days. So, Here we have a very rare machine, the Australian spec only 4L0 250cc cylinder!  (paint just done at this point, so looks glossy, but will dry Satin) (whats the betting this pic turns up on some other forum in a couple of years where someone argues that there really was a 4L0 250 in Aus... hmm... I should rename the pic as 5E1SP or something LOL. I blame google images who will link this without a thought and then some pinterester will claim it as theirs... in the modern world there are so many who copy and claim. Let's watch it unfold |
