rebuilding a 1982 XJ650 Seca; preparing to re-assemble the crankcase and getting lost in all the recommendations and opposing bad reviews I've found on various websites... too many manufactures with too many products... maybe I'm over thinking it, but I'd hate to find out 6 months from now that I didn't think about it enough! One of the lead recommendations is Yamabond... I look it up and I see there is a Yamabond 4, Yamabond 5 and others... both 4 & 5 sound like they might be appropriate but hard to determine which is best for this application from the limited info I can find... Threebond seems to be another top contender - with too many choices and recommendations... which one is really right? seems like 1194 might be the best, but found some info that suggests that it has been replaced with 1184?... but nothing quite definitive, and no one in my Western Canada neighborhood seems to sell Threebond anyways! Permatex seems to be the lead brand at my local retailers, and they have a product called Anaerobic Gasket Maker part # 51850 / 51813 that sounds like a readily available alternative.... so... what's the best seal to use?? Cheers!
