chris_sims1981 Posted April 4, 2014 Author Report Share Posted April 4, 2014 I measured and I got 4 5/8 inches - 2/12 inches which gave me 2 1/8 inches. Quote Link to comment Share on other sites More sharing options...
sstaton1983 Posted April 4, 2014 Report Share Posted April 4, 2014 I measured and I got 4 5/8 inches - 2/12 inches which gave me 2 1/8 inches. That equates to roughly 54 mm..witch would be stock stroke. Quote Link to comment Share on other sites More sharing options...
chris_sims1981 Posted April 4, 2014 Author Report Share Posted April 4, 2014 Ok cool, then I was sold the wrong piston like I thought in the beginning Quote Link to comment Share on other sites More sharing options...
chris_sims1981 Posted April 4, 2014 Author Report Share Posted April 4, 2014 the only markings on the crank was 29L and on the rod was YAMAHA on one side and 2T2 C and something else that I couldn't make out Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted April 4, 2014 Report Share Posted April 4, 2014 I've never seen a Yamaha stamped rod Quote Link to comment Share on other sites More sharing options...
gonzodesign Posted April 6, 2014 Report Share Posted April 6, 2014 (edited) 29L is a stock stroke and a 110 rod, 29M is a 115 rod, but a 2T2 rod is from a 1977 to 1979 RD 400 road bike and is 115 mm long Edited April 6, 2014 by gonzodesign Quote Link to comment Share on other sites More sharing options...

chris_sims1981 Posted April 7, 2014 Author Report Share Posted April 7, 2014 29L is a stock stroke and a 110 rod, 29M is a 115 rod, but a 2T2 rod is from a 1977 to 1979 RD 400 road bike and is 115 mm long Would this make it a stroked motor? ^^ Quote Link to comment Share on other sites More sharing options...
gonzodesign Posted April 7, 2014 Report Share Posted April 7, 2014 I was just refering to rod lengths and the odd 2T2 rod, that paticular rod has (I believe) a different oiling slot for the bottom bearing and was not intended to run as high of RPM or as hard as a Banshee is run so if thats the rod he's using it is 115mm long but may not be the best choice for a banshee.

gonzodesign Posted April 17, 2014 Report Share Posted April 17, 2014 I found out that the 2T2 rod has a 20mm OD upper rod end where a Banshee will be 21 so a Banshee wrist pin bearing will not go in the rod you must use Yamaha RD400 bearings!! not a good scenario to be in.
