My ride is 88 trx250r with ported hiv rev cylinder, fmf fatty pipe, pump gas, 170 compression, 38 keihin, 13/38, stock reeds & ignition. Need help on water pump leaking out and oil leaking into water. Water pump built 2 times, all new, first 15 min runs with no leaks, 20 minutes into run and water leaks through bottom hole and clutch oil goes mixes with water. Local shop built 2 times, cost over $150 each time with new parts, now water & oil leak again. Going broke, whats the problem, need to ride for thanksgiving! Posted on both forums.
