Sum how i have managed to strip one of the exhaust stud holes on the bore so now if i put a stud in it just spins round n round. what can i do apart from buy a brand new bore. any feedcack is appreciated :beg:
try a local bike shop or engineers and see if they can put an insert in, shouldnt be too costly and will save you buying a new kit.
Hi. Whats needed is a helicoil insert as yellasei says, this is what they are. http://en.wikipedia.org/wiki/Helicoil Any good local engineering firm or local garage should be able to supply and fit one for you cheap enough. Its easy enough diy if you have the tools and are careful. Any motorfactors should sell them as a kit form with a load of inserts a fitting tool and drill bit. http://cgi.ebay.co.uk/M6-X-1-0MM-HE...ultDomain_3&hash=item5d2aa07fa4#ht_2446wt_905 You must get the right size kit for the thread your repairing not sure as to what size is on your cylinder but it should be metric, for example if you needed to fit an M6 stud you would buy the M6 kit. Another cheaper way to fix it would be to drill and tap the hole to the next size up and fit a bigger stud or bolt, if there's enough metal to do so.
ok cheers mate that makes more sence to me now but is m6 the same as 6mm? http://www.donotlink-pedstop.co.uk/p/Exhaust_stud_6mm_for_cylinder_manifolds_X_1-1485.aspx thats the studs that fit my bore would u know what size insert i would b needing.
Hi I just checked the stud on my engine which is the same as yours and its a M6 so you would need an M6 kit. The diameter of my stud is 5.9 mm.
i jus been to a local car garage n they said helicol is not a diy job atall 1 mistake and thats it new bore. has any 1 done this themselves??
Take the bore off and have someone experienced do it, have to agree, not a beginers jobby(not rocket science either though), small mistakes such as drilling a pissed hole or snapping a drill bit inside , drilling too deep could prove a major pain in the ass, if you do decide to diy then remove the cylinder and take your time doing it.
have done helicoils myself and they are easy to do aslong as your careful and take your time retaping it to the next size isnt really a great way as arent the holes on the exhaust just the right size for the m6 stud
Got it sorted :yahoo: my friends dad has a garage n had a look at it. i whipped the barrel of n he done the insert in about 10 minutes. thanks for the feedback guys
Glad you got it sorted, sounded like your local bike shop were having a laugh trying to sting you for a new barrel when all that was needed was a cheap insert.
haha yh they r not very useful. the person who answers the phone aint got a bloody clue about peds lol its ridiculous!
