Gp1300r Jims mod ride plate
I recently fitted an r&d ride plate on my gp1300r that has had the Jims mod made to it...
the plate made a fairly good speed improvement, maybe 2 or 3mph so very happy with that.
problem is there is bounce in the ski now unless its fairly close to top speed....
Has anyone any experience or suggestions on this?

looks like the side are hanging below the shoe. picture is cloudy is the center section were the skeggs are rounded or squared off.

much better plate alignment to shoe is good, Make sure the sponsons are stepped and might have to add 120 thousands shims to trim tabs.

So get 8 120 thousands shimms and put them under the tabs one on each bolt... do you know what 120 thousands is in metric? we dont use those measurement in ireland and i cant seem to find anything on the web about converting that!
Thank you again.

120 thou is 3mm .. yes put 3mm flat stainless washers under each bolt . If you put a straight edge under your hull and across your jims plate make sure the plate is higher than the hull.so its not draging in the water . Try spacing your plate down so the front of it is nearly flush and the rear(sides of plate ) is slightly higher .dont have any of the plate lower than the hull . The centre part of the plate under the pump should have around 23mm (920 thou) gap on the rear from a straight edge . start from around these measurements and adjust from here . I hope you can understand what im saying here ... im no expert and every ski is different ..good luck
