November 9, 201411 yr I'm seeking opinion on the best options for a Matchless engine. Is there any benefit in using the older 350 bottom half of the engine? It is smaller, lighter, and the smaller flywheels may suit modern sections better. Has anyone tried this with the later shorter con rod, which should give better torque? Or is there a better option?
November 9, 201411 yr I use the earlier type 350 motor in my rigid Ajay,still at 350cc with the long rod.I cant comment on the shorter stroke motors,I can only say I'm very happy with the characteristics of mine.But one thing I have found that I was told years ago by the late John Scott, is that its best to use the roadster narrow flywheels rather than the original wide comp ones.His rigid had an old iron motor which he was a great favourite of his. Steve Allen's Matchy which is still very original,(Gerry Holdstock's bike) is flat and very unwilling to rev out like mine will,I think because of its wide comp flywheels.But both bikes will find grip amazingly well, even with a less than new tyre with 8-10psi in it. Brilliant engines to use,very satisfying to creep up muddy banks were often more modern bikes struggle...
November 10, 201411 yr What about 350 engine with Alfin alloy barrel, Ariel conrod, A65 piston, 75mm bore x 93mm stroke = 410.9cc. Rides very well!

November 10, 201411 yr Interesting... I tried that on my Ariel,there was so much play in the mains that rotor chewed up the stator ! Do you have any photo's of how you mounted it etc ?
November 11, 201411 yr can i ask why a trick matchless with modern pvl electronics is listed under pre 65, oh i wish i was a scrutineer in pre 65 trials instead of sprint and drag racing,
November 11, 201411 yr If you are asking a question like that then you would not last long as a scrutineer in pre 65 trials!

November 12, 201411 yr Interspan is the answer to the Holy Grail ....................... I know Ken,trouble is I'm stuck in 1950... I WILL make it work.
November 12, 201411 yr I know Ken,trouble is I'm stuck in 1950... I WILL make it work. Ten to eight ? Edited November 12, 201411 yr by b40rt
November 12, 201411 yr Ten to eight ? No,the year... I think I'm a victim of being born too late,apart from the internet and modern medicine there is little I like about the 21st century.
November 12, 201411 yr i have been using lucas sr1 mags on all of my competition bikes mostly panthers all start 1st kick hot or cold, matchless used them as std before 1965 so problem solved. will.
