recently bought the bonnie , real problem with primary chain too tight but unable to loosen adjuster . grateful for any ideas
after removing the cover , I tried several screwdrivers into the adjuster but could'nt engage with any slot . Out of curio, I inserted an imperial allen key which seemed to engage with a slot and spent half an hour turning and turning the key but nowt happened. I know its supposed to be adjusted with a small driver , but nothing works. My next move is to take the cover back off and see how the adjuster is fixed onto the bottom of the inner case. I have trawled ebay and found a complete adjuster in the states , but I need to investigate further before I buy a replacement
when checking the tension I think you are supposed to put some weight on the Kstart which effectively loosens the top run of the chain @darkman will hopefully confirm if this is right
One possibility, i prefer to just give it a big wiggle up n down and get it around 3/8 to 1/2 inch play.
Bob Rout I had the same on my silver jubilee. I screwed out the pinion at the front and pulled it through that way then replaced the tensioner. Also I was always taught that the free play was at the top and only a few mls. Regards Joe.
thanks for replies , I will remove outer case again and investigate further . I am wondering if the actual adjuster part is actually in place , or removed or broken by previous owner , will let you know Bob
