CockneyRick Posted October 11, 2018 Posted October 11, 2018 Open to a wider audience here, looks like the starter clutch has failed on the 1127 drag build. Never entered my head as i've not had one fail ever before, only my GS1000 did quite a few years back. Anyhoo, cover off to watch it & the starter turns the idler gear, which in turn rotates the large gear c/clockwise. I know this should then lock & force the inner to turn on the crank, but this ain't happening. Trying to turn it manually clockwise is ok & other way is not. But under starter load it spins freely! I have never had to fix one of these, so don't have the specific tools. Any tips would help, plus best place for rebuild kit, or dump it & get a 2nd hand one? Quote
Swiss Toni Posted October 11, 2018 Posted October 11, 2018 Rebuild it, Rick. The rollers get 'threepenny bitted' with age, so a s/h one may be no better than the one you have. Everything will be available as a spare. Just watch out for the small springs getting airborne! 1 Quote
CockneyRick Posted October 11, 2018 Author Posted October 11, 2018 As said, never had to take one apart, so assume the design is an improvement on the GS? No welding etc needed? And tips for removing, as i don't have specific tools, but a normal garage full of useable tools. Quote
CockneyRick Posted October 11, 2018 Author Posted October 11, 2018 (edited) Searched Fowlers & Robinsons & no sign on their parts of the rollers etc? Eblag only has one for the GSXR1100F/G/H 1052 engine, mine's a GSX1100F 1127? No listings for anything 1127 or 1157? Edited October 11, 2018 by CockneyRick Quote
CockneyRick Posted October 11, 2018 Author Posted October 11, 2018 Looks like i've answered my own question. The starter clutch on 1127-1157 engines has many (30+) rollers, so it's not a repairable part! And when i took the big bolt off, it was literally hand tight, which could explain the free spinning of the large starter gear! More things i'm finding out about this engine as i go along! Quote
Swiss Toni Posted October 11, 2018 Posted October 11, 2018 Surprised no spares, Rick! Have a good look at the rollers then. If all looks serviceable, re-fit & Loctite it to specs. Loose bolt might have been your problem all along. Quote
CockneyRick Posted October 11, 2018 Author Posted October 11, 2018 It was! degreased bolt & crank end surface. Reassembled, Loctite & torqued up. Bingo i have an engine that turns over Sometimes it really is the simple things. Why it was loose is a baffler? 3 Quote
eliterate Posted October 15, 2018 Posted October 15, 2018 This reminds me of my first 1052. Bought it with a serious rattle/knock. Turns out that the original starter clutch was held together with 3 rivets and this one had sheared one off. No damage and got the bike for a case of beer. Replaced with the updated clutch (looked exactly as above) and voila. Glad you got er sorted. Quote

CockneyRick Posted October 19, 2018 Author Posted October 19, 2018 Not at all, i acquired the engine whole, & as i thought unmolested Quote
