i really wish you could have seen the mess i ended up with before i got it running, maybe then you would sit back and just say, oh holy shit maybe this guy does know about the hunk of crap motor in this particular tracker, im telling you, the "mechanic" that did the rebuild had a head that wasnt too far from his ass and shouldnt ever touch a wrench again, he turned a decent motor into a paper weight that still somehow runs, the walls are scored, crank has been machined so much that the bearings almost dont fit, timing was way off, harmonic wasnt ever torqued so it spun the timing key, cam is supposed to be new and is worn so much that it almost doesnt have any lobes, timing tensioner was welded back together, wiring was everywhere, starter hardly worked, valve cover was on backward causing it to leak, exaust has been cut to right behind the door, straight piped, so im sure the valves are burnt up, oil pump was shot, 2 quarts low on oil, and all this is after a rebuild less than 1500 miles ago? its a nickle and dime machine and just not worth it anymore, i could build all three of my 350s for around what the 1.6 would end up costing after parts and shipping costs, if you really want the oh so perfect 1.6 pay shipping and ill send it to you, its that worthless anymore. i am not saying that suzuki is a bad motor by any means, if i would have gotten a low mileage stock tracker im sure it would be different, but thats not the case, the only thing done correctly on my rig is the lift that was installed by calmini, other than that im afraid to see what else was riged internally with a welder to get a couple more miles. to tell you the truth, i am impressed with my tracker given what it is and whats left of it, but its just going to be cheaper to do the swap, i have no interest in trying to rebuild a motor that has been abused and will never run right again.
