and I have only used three plugs including break in(16 tanks). I am not experiencing a week bottom end as some people have stated. MSR spring, flyweights drilled to 4mm, nut at 10.2mm , 16-49 for big tires and 17-50 for small tires. Let it eat.
I definitely feel the amount of time getting this Ningee to loosen up is well worth it. MH7 if you've got the time and a break in bench you should get one. Follow Mikes break in and enjoy...cheers
Did you notice that type of wear pattern on the piston/sleeve during early break in? Mike told me to hit it for two or three more tanks at 240F on the track then shoot for 280F. Ron C. also told me they start the MSR spring at 9.2mm and toss it out by 10mm because it looses it's "memory" and your clutch setting will not be consistent.
