skunkrider2 Posted October 22, 2015 Share Posted October 22, 2015 (edited) I bought a 1994 GSXR 750 WR, its been stood for over 10 year with original 21000 mile (engine has been ran so ok on this side) Im trying to make into streetfighter over the winter with the goal of dropping in the 1127 motor. Problem I've got is the main subframe bolts to main frame (allen head) will not free off, the heads are rounded away so will not take the 6mm allen socket. Anybody got any ideas of how to remove (before i try to drill out) Got same trouble with battery box to subframe bolts, inaccessible to get drill in, and can't remove subframe because of above?????? Going to be old school streetfighter, with a 916 style seat unit ect, ect. And finally turbo'd (but thats a long way off)Any help would be greatly appreciated, Edited October 24, 2015 by skunkrider2 Quote Link to comment
ziggy Posted October 22, 2015 Share Posted October 22, 2015 Have you tried hammering torx bit in? Quote Link to comment
skunkrider2 Posted October 23, 2015 Author Share Posted October 23, 2015 Have you tried hammering torx bit in?I have Ziggy, flat sides (inside) have rounded off. Out of the 4 bolts, only one has come free, the other three are stuck fast (I'm guessing they have never been undone since put in by suzuki 21 year ago!) I know steel will weld to aluminium after time, and I guess 21 year is time enough . Quote Link to comment
Captain Chaos Posted October 23, 2015 Share Posted October 23, 2015 weld some other bolts on the stuck ones, the heat will free them and then they can be loosened. Quote Link to comment

snoorder Posted October 23, 2015 Share Posted October 23, 2015 These steel bolts are usually stuck in the aluminium frame. Just some heat and then your torx back in it might work. Otherwise drilling them out is the way to go. Be sure to get the correct fine thread pitch when buying new bolts. I beieve they are M10x1,25.Cheers. Quote Link to comment

Hate drilling!!!! Oh well if thats what has to be done the so be it. The subframe has to come off as it needs raising quite a bit to take 916 seat unit. Quote Link to comment
irish Posted October 24, 2015 Share Posted October 24, 2015 hello mate i would forget putting a 1127 or bandit motor in the wr frame as it will not fit you have to modify the head stock for this to work the best way out is to fit the water cooled 1074 engine anyway hope this helps you out Quote Link to comment
badgerkdd Posted October 24, 2015 Share Posted October 24, 2015 If you can get a dremmell with a small fibre disc on you could cut a slot for a flat screwdriver bit then take an impact driver to it? I did that to the stuck screws in the battery box area and managed to get most free.I've just had a similar problem with cap head bolts on the lower crankcase and had to drill it out eventually. Sometimes its just easier and quicker, I spent several hours doing all the other stuff, welding etc. but in the end came back to drilling it out, took 5 mins and was easy to get the bolt remains out afterwards.

GSxr W motor is a little bigger than most if anything. Quote Link to comment
vizman Posted October 24, 2015 Share Posted October 24, 2015 (edited) are they [the engines] not a bit shorter from front to rear the waterboilers ? Edited October 24, 2015 by vizman Quote Link to comment
markfoggy Posted October 24, 2015 Share Posted October 24, 2015 I'm thinking our new friend Irish ( welcome along by the way) is suggesting injecting an SRad or K? series motor that would need a cylinder head/block mount. That would need headstock fabrication. Busa FTMFW, BTW, innit! Quote Link to comment
vizman Posted October 24, 2015 Share Posted October 24, 2015 (edited) I thought he was suggesting putting the last of the cradle style 11 water boilers in the 750, which requires little work Edited October 24, 2015 by vizman Quote Link to comment

metallicaman Posted October 24, 2015 Share Posted October 24, 2015 He does say 1127 motor which would suggest the oil boiler not watery motor, have seen it done and can't remember the headstock needing any adjustment, the front downtubes on the cradle do need modifying to get the exhaust headers past as the oil and water engines have different cylinder spacing...

markfoggy Posted October 24, 2015 Share Posted October 24, 2015 Can't link, but that explains George 1100 's post in Hayabusa's comments in another post about exhaust clearance on 1127 into 750 W framesI think that I'll stop worrying about my build until I discover that I've got an epic fail on my hands due to an impulse buy of a Sanctuary Exhaust System that doesn't fit.I'll blame the beer.

markfoggy Posted October 24, 2015 Share Posted October 24, 2015 Wow, you're going to be fun.You'll need to load your photos to somewhere like photobucket or instagram. Then you can copy and paste them here.Grab hold of a local 10yr old, who understand these things and make it happen. We'd love to see.Hey, I'm not taking the piss about 10 yr olds, It's how I got on the internet 15 yrs ago and how I learn how to do things on my mobile phone now! 2 Quote Link to comment

skunkrider2 Posted October 24, 2015 Author Share Posted October 24, 2015 Sorry i should have made it clearer in the beginning, my plan would have been the 1127 oil cooled engine in the 750 water cooled frame. I was led to believe it was a 'straightish' swap. If not ill keep the 750 motor (as its only got 21000 on the clock.) and start another build with the 1127 motor.I'm open to suggestions on which way to go with this build. Quote Link to comment

(£75 later) Saying that i always wanted one as was going to try and polish brake callipers, so money well spent. I'll give that a go with disc and impact driver, before drilling. 1 Quote Link to comment
