Bobby Posted January 4, 2020 Posted January 4, 2020 Hey guys, as the title, I'm in the process of fitting APE studs etc, tightening them down to correct torque to notice not all are sat at the same length, just looked at my old ones to find 4 are slightly shorter. Now, I did not pay attention when removing them nor does my workshop manual tell me which 4 are the short ones are where they go, Can anyone please help me. Cheers bobby Quote

Gixer1460 Posted January 5, 2020 Posted January 5, 2020 Not if its aircooled ! Or a 750 ! Need all the info for confident advice. Quote
Bobby Posted January 5, 2020 Author Posted January 5, 2020 Indeed, I should of given more information.. it’s for a 86 GSXR 1100 1052 motor! the brand new APE studs are all pretty much the same length, a couple are a fraction shorter. my original studs I have 4 shorter. ive never known head bolts to be different lengths! cheers bobby Quote
1100fred Posted January 5, 2020 Posted January 5, 2020 Yeah your right do need all the info first,you should have four shorter on a on 1052 Quote
Gixer1460 Posted January 5, 2020 Posted January 5, 2020 This would confirm the 4No short studs I'm guessing the 4No short ones are for the oil ways as they aren't defined? I'd maybe use your shorter studs in the centre oil ways although 4 matching would be better. Using long studs in short positions can't hurt unless you bottom out the threads before full torque is achieved. Quote
Bobby Posted January 5, 2020 Author Posted January 5, 2020 Cool, so they are 4 shorter ones, as said the APE studs are all about the same length, like you say, if they torque down ok with thread to spare then can’t see why it would not be all ok. the shorter ones probably came from the middle! cheers gents Quote
