jc2 Posted March 11, 2013 Report Share Posted March 11, 2013 (edited) Can anyone tell me if a 250 Italjet top-end will bolt straight onto a 350 Italjet bottom-end, or is there diff stud spacing, diff little end dia etc?

woody Posted March 11, 2013 Report Share Posted March 11, 2013 If it's like the Bultaco, no you can't do it for the reason you state - stud spacing plus thicker liner. Try Steve Goode motorcycles here in the UK, he may still have some Italjet stock left and can probably answer the question http://www.stevegoodemotorcycles.co.uk/index.html Stevejgoode@aol.com Quote Link to comment Share on other sites More sharing options...
ask greeves Posted March 23, 2013 Report Share Posted March 23, 2013 (edited) Hello Woody, Yes the 250 will fit directly onto the 350. If your doing the conversion because of lack of 350 piston and knowing a bultaco piston will fit, be aware the original 250 italjet bore (actually 238cc!) was chrome, so would need iron rings. Also bultaco small end smaller, but can be sorted with different caged roller small end bush. Edited March 23, 2013 by ask greeves Quote Link to comment Share on other sites More sharing options...
