Dose anyone know what the specs are, lift, duration and timing are for these cams.

and how they perform in a touring bike with 88 inch

 

Andrews TW21 10 30 40 8 220 228 18 100 106 103 0.498 0.498 0.134 0.121

Bartels JM20 15 31 44 12 226 236 27 98 106 102.0 0.500 0.500 0.161 0.138


Bartel's is no longer made. The Andrews TW21 is so similar it can be considered the same. Works well in a bagger of 88" and better in a 95" with good torque from 1700 to 4500 rpm.

 

do you know where to get a JM20? designed by joe minton. it is similar to the 21 but more of a cross between the 21 and 26. it will perform well in an 88 or 95.

 

Found a set on ebay, seller had i believe two sets

 

were they gear drive anad do you have sellers info? how much did you have to pay? thanks jeff

 

They are chain drive cams, i paid 125.00 plus shipping, you can try this # 1-800-841-6771, Timothy Smith, Sunshine auto recycleing

 

do you know how many miles on the cams? You got a good find there. Some say that is the best mild build bagger cam on the planet.
