Fortunately they make both a NU2205 and a 6305.... to keep the balance right??? This has now got me thinking..... if I buy these, what I'm going to do for a dummy rear hub and end plate?? Now i'm really thinking ...what about the big end...will that that need dummy shims or not??? Maybe the use of these dummy bearing in a dummy engine will help with the piston problem??

(again) - mind that threaded back brake cable they "invented#" was a great piece of kit (sorry Knowledge ..

I'm genuinely proud to say I do not now nor will ever have any BGM products on my bikes.....
Most people with a bit a of sense will listen the wise words of Public Enemy...... "don't believe the hype "
