Air Filter to SU Carb - Bolt Size

Recommended Posts

Happy Christmas ... my first day in the garage for nearly 5 weeks sees me hit all kinds of frustrations ... but I know you guys will love some distraction from the family Christmas

I recently got two K&N Air Filters from Ebay for my 1 1/4 SU HS2 ( Spitfire MKII ) - but the bolts supplied don't seem to fit the casting on the carb body - The original air filter box was attached with 4 x HB867 - longish bolts ... I need the equivalent threaded bolts short enough to fit inside the K&N units.

The originals look like UNC - but can anyone tell me the bits I need before I buy lots of random bolts - Thanks

I think you are right about the UNC......  They are 5/16" and 3/4" long should be plenty.  Suggest a spring washer and/or loctite when fitting them.
