hey, im new to the forum and i have a 99f4 600. i changed the plugs out shortly after i boughtmy bike in may(i put them in very carefully with no resistance). bout aweek ago a sparkplug popped out. i tried to replace the plug but it would not seat. turns out the threads are all gone. i am having a hard time finding a helicoil in the right size {10mmx1.0}. does anyone known where i can get one? does anyone have a better solution? has anyone ever had this happen to them before?
help!!

 

never happened to me on my bike but did on my beetle. Ive heard it before though for our bikes so I know there is a helicoil that will work. Threaded insert is a better solution though. I had to special order the thread inserts for my beetle cuz it also was a strange size.

 

huh, well i tried to find the kit for cheap but it looks like the best price is about the same price the local bike shop quoted me to fix it. so i guess my prob is solved (i hope). i will let you know how it goes

 

just talked to the shop and they put a heli coil in for $125.
not to bad. once i fix the fairings and get them back on i should be in great shape. thanks for the help.

 

ouch! your in alot more trouble then you think.Your gonna have to have to pull the motor and Take the head off.It hapened to me already on my gsxr.Once the head is off then you use a hexicoil kit.Advanced auto parts sells a kit for 20$ and the size you need.Instead of paying the shop.I'd pay the 20$ and do it yourself But it involves work..Maybe pay the garage to do it.

 

Grab a workshop manual off my siggy, save yourself some cash in future !

 

Yeah I wouldn't trust the shops work if they didn't remove the head to do this job.

Your cylinder is probably full of aluminum shavings right now...

 

i got the bike back put i havent started it yet. i asked the mechanic if there would be shaving and he said that they would have blown out with the plug. he also assurred me that they got all the shavings out....? its ken brits in johnson city, tn a very highly trusted shop.

 

before you start it.I would remove all spark plugs and crank it over and try to blow if there is anything out..only my thought..I mean it wont hurt to try..?..

 

Removing the sparkplug and then cranking it over is not going to blow metal shavings out. compressed air would be your best bet or a shop vac with a small attachement you could fit down the hole. its too bad the heads are aluminum or you could use a magnet. The proper way to do this is to remove the head, but alot of shops won't do it. Youmay get lucky and all be alright. Then again you may have a timebomb there. Only time will tell. I personally will not use helicoils ever again since I've found thread inserts. Helicoils are temperary fixes, where as thread inserts if installed correctly are permanent.
