Hello All
Have been doing some research on the question on will a srx400 1jL 1985 cylinder head fit on to a srx600 1jk 1985. I have had some difficulty in finding technical information on the srx400 and there is some differences between 400 and 600, carburettor and valve sizes are difference.
There is two things I need to find out the size of the cam sprocket and cam drive sprocket on the 400 and the lenth of the cam chain of the 400.
If I can replace the 400 head on to the 600 engine, should I run with the 600 carb or with the 400 carb?
Input or advice would be helpful
Regards Gardener
