1996 intruder 1400
 

hey guys i recently bought intruder 1400 and after cleaning the carbs and doing a full tune up it fired right up but didnt run properly
after lots of inspections (spark plugs ,battery ,gas pressure ect) i did a compression test and on the front cylinder got 135 and rear 65
then i went ahead and did a leak down test and there both leaking from a exhaust valve now. at this point i don't know what to do how hard is it to get the head out? does anyone here a a service manual i can have or buy?
