No1kimchi Posted July 22 Report Share Posted July 22 Hi guys. Got 2018 txt 250 and tried to replacing the top end but I really can’t find way to how to tighten front cylinder base nuts. Plain ring wrench doesn't fit at all neither most slim wrench(signet 30493) I got. Was tried to tighten with open end wrench but seems like nuts are gonna stripping. Any idea how to tighten these nuts with torque spec?? Quote Link to comment Share on other sites More sharing options...
kurtas Posted July 22 Report Share Posted July 22 On my gasgas enduro bike I went to the shop and bought a cheap ring spanner and ground the outside down until it fit. Scientific torque spec I used was almost as tight as I could do it by hand and then give the the spanner a couple of light hits with a hammer. 1 Quote Link to comment Share on other sites More sharing options...

ChrisCH Posted July 22 Report Share Posted July 22 A flare nut spanner might be the answer. It is a type of open ended spanner with a bigger purchase. An example is here: https://uk.rs-online.com/web/p/spanners/2358029?cm_mmc=UK-PLA-DS3A-_-bing-_-PLA_UK_EN_Catch+All-_-Mechanical,+Fluid+Power+%26+Tools-_-2358029&matchtype=e&pla-4574999185500285&cq_src=google_ads&cq_cmp=554644865&cq_term=&cq_plac=&cq_net=s&cq_plt=gp&msclkid=095f50e9815a1b0f8679389616c21e79&gclid=095f50e9815a1b0f8679389616c21e79&gclsrc=3p.ds&gad_source=7 Quote Link to comment Share on other sites More sharing options...
greychapel Posted July 24 Report Share Posted July 24 1/2 inch AF open ended will be a good tight fit on 13 mm nut? Quote Link to comment Share on other sites More sharing options...

totty79 Posted July 25 Report Share Posted July 25 Crows foot spanner with a torque wrench Quote Link to comment Share on other sites More sharing options...
lsv Posted July 25 Report Share Posted July 25 (edited) If you want a good open end jaw spanner then a Stahlwille No 14 or No13 pattern combination will not spread and round the nut or you may be able to get a No21 pattern ring spanner in there. They are "simply the best" IMHO. And another thing you could do is to change the nuts from 13mm hex to the 12mm hex that are found on better quality bikes like Hondas! 😉 Edited July 25 by lsv addition Quote Link to comment Share on other sites More sharing options...
