| Post subject: | Early 250 differences |
I was wondering if ther early 250's have any differences similar to what may be an early production compared to a later one ( kind of like Maico did with mid year changes). I used to have a 250 that was titled as a 1973. Are there any changes with the models designated 1974? One thing I have noticed is the carb. It's a standard Keihin, but the fuel inlet on the carb is different from the 73 I had. This one is angled at the ten o'clock seting and held in place with two screws. If I recall, my old one was cast in the carb. I am wondering about the shocks as well. They appear to be Honda shocks, but are not the finned Showas. I guess they could be from another model, but I spotted a photo of a 73 on another site with similar shocks. Other than the DG pipe on this bike, it seems to be original down to the unbroken number plates - side and front. bars, levers, kill button are all stock. Heck, the head bolts appear to be untouched as well. Any ideas? Thanks! |

| Post subject: | re early 250 |
I know there is a difference with the cranks.I have a early production 73 model cr 250 and the crank appears to me a machined part and it looks like the metal is berillium (sp?) and the cranks from a 74 and a 75 model and those cranks are cast units.the crank from the 73 has a bronze like color to it and the later cranks look like plain iron.anyone have any insight on this? the 75 model has a slightly longer rod than the earlier models I guess because of the way the mount on the crankcase where the jug bolts down is different. |
