I have a 1947 model 18 which I am returning to the road after a 60 year lay up. There is a slight kink in the top tube just in front of the carb. Should it be there?
Can you upload a photo? I have a kink free 1936 Model 18 but a picture would be useful..
A bend in the top tube is not unusual, see photo of a 1956 frame (50/ES2/19S). 1950 ES2 has a similar bend.
Is similar although it's plunger suspension. I suspect it's to clear the extra height of the OHV engine and allow for the rockerbox / head to be removed.
Hi Dean all post war cradle frames have a curved top tube ,it may be an idear to get the frame allighnment checked ,i have a 1947 16h and a mod 18 both had sidecars fitted at some time and both had bent frames Regards Roger
I’ve added a picture, according to other responses it should be there. Thanks
Yes that looks the same as mine
Thanks for the alignment tip. That is something I have considered as this bike once had a sidecar according to the 59 tax disc. Don’t know what became of it though. Where did you get you frames sorted?
A bit baffled. Why assume your frame needs 'sorting'? Everyone has said the top tube shape is correct. And it's hard to see how a crash would bend it up like that.
Put wheels on and see if they are parallel or if there is a twist.
I presume Roger Deadman (above link) has had a twist else where on the frame. Looks to me if the top tube should be like that.
Thanks Dean Ghest
My 16h 1947 had a small lateral misalignment (not front), in the frame. I managed to take it to its place, with long force levers and a good fixation anchor (without temperature) (I hope you understand the translation)
