Title: those low profile sump screws... Post by: booger on October 06, 2021, 06:34:06 AM [bang]
I have the deep sump Monster, with the troublesome low profile sump screws holding the sump plate on. Supposed to pull the screen and inspect every two oil changes. 9k miles and 14 years and this plate has never been pulled. Partly my fault for not getting to it sooner, and partly the shop's fault for not doing it at the 7500 service. Also my fault for not specifically asking for it at the last service. How much trouble is it going to be to drill these out? Tried to remove these screws and nope. The heads have turned to cheese. Started to drill one out and quickly aborted. This kind of crap makes me super nervous. The way I see it there are a few ways to proceed: A) grind the heads off, pull the plate, and grab the threaded remains with some vise grips and wiggle till they begin to move and/or Dremel a slot to turn them out with a screwdriver and B) drill them out starting with tiny drill bit and progressing to larger C) get a left handed drill bit and try it that way So I had to leave it be for the time being and just change the oil. Am I in any serious trouble here? I mean the bike runs strong and has 12.8 bar equal compression in both cylinders. Curious to see what's in the screen though. If you have a bike with the same engine, how has your sump experience been? Title: Re: those low profile sump screws... Post by: Duck-Stew on October 06, 2021, 09:15:51 PM Get the screws out. Best way to check the health of the engine.
I’ve used a hammer and chisel to get them turning. If you drill the head(s) off of them, the threads come out easily as they're no longer under tension. Title: Re: those low profile sump screws... Post by: koko64 on October 06, 2021, 11:05:01 PM Had to do the same to a Multi1200 sump plug. Impact driver just ate it, so cut a dremel slot (very carefully) and hammer chiseled it. Fitted a Ti 12mm hex head plug to my own 1100 Evo and strongly recommend the same for customers.

Talk about a 3 week oil change because I had to walk away a couple times. Two came out fine, the other two I had to slot. The last one sucked the most. As I took them out I replaced them with SS screws to keep the tension on the plate. That still didn't help on the last one. I think the previous owner put a thread locker on there.
