Picked up a 13 pro 800 163 3" with 1600 miles on it. Has a boondocker gtx 2860 with tial and ebc controller. Initial problem was hard starting. Took at least 10 to 15 pulls to get it going. Once started for the day it was one pull. Also had a slight low end bog that I had to sometimes feather through. I ride 8k plus, 100% av gas and 10 psi boost. Done for the season, I started taking the sled apart. Noticed alot of the exhaust Springs were very easy to take off and stretched. Also noticed the spark plugs were a bit snugger then finger tight.
Did a compression test and 125 psi @ 1200 elevation on both cylinders. Next I did a leak down test and found the wye pipe gasket leaking slightly. Put some silicone on it and re tried the leak down test and passed. Continueing on I pulled the reeds. Found one peddle was chipped at the very end, rest looked good. Pulled the head off and couldn't believe the piston to wall clearance (. 020 front to back and .016 side to side). Cylinders and pistons look normal to me for the miles.
So I'll be pulling the engine sometime soon and putting new pistons in. Do you guys think I can get by with 15 pistons and a hone to clear up the slop or do the indy Dan replacement? Also thinking about going with the v force 3r reeds. Would it be beneficial to delete the thermostat?
Few other questions are whether to go with boondocker exhaust Springs or just get new stocker Springs.
Going to throw the green/white exhaust valve Springs, Tony's clutching and sending the primary to indy Dan for machining and shimming for lighting weights.
Any other suggestions while the engine is out would be great!
