Freshened up and ready for the season
I just dropped in two freshly gone through motors today in both my GPR's it has been a long day one is buttoned up the other will be done tomorrow. I will be out breaking these in and tuning for the entire week starting on the 31st at Lake Havasu I can not wait.
My original motor had a 4 corner sieze on the #1 cylinder at about 3 hours run time due to air leak. I replaced that cylinder and piston and also added a new trued balanced and welded crank with polished rods it is a sweet crank Thanks InSaneDiego-Joe for hooking me up on this one. I have balanced all the pistons and repaired some threaded holes in the case with Stainless inserts. reassembled and pressure tested this thing is tight this time. I was running a modified OEM Head but for this trip I will be trying the Riva 41cc Head just to see what it has. I ran the water like Riva shows but will also add a tee in each circuit and dump it over board via 4mm pissers. I have custom 48mm carbs with Novi atomizers and am running 3" cones with outers. Dual fuel supply and premix, Riva Gas valves ,Advent Yam 59 and to add a twist I am experimenting with a fluid dampning coupler. I just got an 800 grate the 2" extension is already installed I will be installing my new 05 pump and dynafly(Thanks Jgustman). I am running stock stepped sponsons and stock shimmed tabs and Jims original Package J-plate.
01 GPR (Thanks OU812 for hooking me up big time here)
this ski came to me with a bad #2 cylinder it had recently had a cylinder failure on #1 and was replaced with new parts I found after pulling the motor the crank was new also. there had been some damage to the case and it was welded and repaired from the inside. I went through this motor completely. I removed the S-3 stinger and replaced with stock stinger and R&D d-plate added wave eaters completely went through the carbs and rejetted to spec, Pro-Tec adapters with Prok F/A's. I put on a modified OEM 150 psi head. will run a 1200 grate R&D plate package spec, R&D tabs or shimmed stock tabs, stepped sponsons and nujet 6.5 island speed cut I will keep the oil injection intact in this one for now. I will also have a solas YF 14/20 and yet to be determined (need to pull it and check it) skat impeller with me.
I am looking forward to vacation.

Speed goals are moderate right now I need some good motor time and then I can start dialing the hulls in I am shooting for 75+ with the 02 and 70 with the 01 I have not filled any holes yet. I will have all the necessary items with me to make adjustments and fill and sand. and plenty of parts to try. Both motors are non ported 1200's I just acquired some ported cylinders not sure when they will arrive so it is for the next engine. I have two scored cylinders in the big bore pile once I get a third I will get them off to Lowell for a 1390 build.
