My 1956 19S (Alfin head) has stripped the threads in the exhaust port. Has anyone had this type of repair done recently, and if so who did you use? Did they do a good job?

AMAL 375 jet block

Forums

Hi, the AMAL 375 seems to have been used on a lot of bikes, however the final digits - in my case 375/48 for the Navigator provide the configuration info - unless I am mistaken. This is with respect to the jetting and bore sizes etc.

Roadriders

Forums

hi, I was going to change my tyres to roadrider's 100/100 front and rear but can't seem to locate them. I can only seem to locate 100/90's, have they stopped making the 100/100's?.

is there any real difference anyway?.

Foreign bodies

Forums

I have been given a 1957 99 engine, and frame. Not knowing why it was put out of service I thought I would have a quick look in the chain case where I found these two bits of metal floating around.
