montyhack Posted October 28, 2011 Author Report Share Posted October 28, 2011 Cheers all the other parts came from sandifords but Iam afraid I dont wish to deal with them again but will try pidcocks. still not sure if they will supply a conrod kit but I will keep looking as I cant stretch to a new crank yet Quote Link to comment Share on other sites More sharing options...
ham2 Posted October 29, 2011 Report Share Posted October 29, 2011 Hi , no the engine is not the same or even similar to the cr250, you shouldnt have problems with parts try sandifords honda/montesa or pidcocks honda So was it just an urban myth that the cr250 had the same 315 bottom end?

baldilocks Posted October 29, 2011 Report Share Posted October 29, 2011 i think the the clutch plates from one of the MX bikes fitted, maybe people jumped to a conclusion from that ? I think Honda only sell cranks for the MX bikes from memory but you can probably get aftermarket con rods, hopefully one will fit the 315 ?

samandkimberly Posted October 29, 2011 Report Share Posted October 29, 2011 I think there's a very good chance the rod kit is the same as *some* Honda. There are lots of rod kits available from good aftermarket places and you can get there basic specs. Here are the basic specs of a cr250 rod from Wiseco: Material Type: Quote Link to comment Share on other sites More sharing options...
motomanandy Posted October 31, 2011 Report Share Posted October 31, 2011 They are not the same mate i researched this for a friend some time ago all the cr250 rods are too long!there are some very close matches ie; old ktm rods but i never found a perfect match. the complete honda crank is Quote Link to comment Share on other sites More sharing options...

b40rt Posted October 31, 2011 Report Share Posted October 31, 2011 (edited) I thought that was quite cheap! in comparison the sherco 250/290 crank is £486 That's because your a time traveler, where everything is more expensive in the future ! You need to adjust you clock, or TC does. Edited October 31, 2011 by B40RT Quote Link to comment Share on other sites More sharing options...
