As of Memorial Day weekend, my WR450F suffered severe engine damage for the SECOND TIME in its life. The repair operation is on hold pending the discovery of a large sum of money. It could be worse, I suppose. My connecting rod s/e went poof and let go of the piston right at the wrist pin. The rod then proceeded forward through my cylinder and got a breath of fresh air. Somehow the case, valves and cylinder head are okay. In an impulse purchase fueled by the despair of losing my prized Yamaha, I found a gangsta deal on a pair of Italian TM Racing dirt bikes. If you haven't heard, TM is the Ducati of dirt, Lamborghini of leaping, Ferarri in the forest, something like that. Check them out www.TMracing.it on the web. One is a 1999 125 EN, the other is a 2001 300 EN. Just say no to valves, they are hand-built 2-strokes. Trick looking baby-blue plastics, Ohlins suspension, Chromoly oval-section perimeter frame, billet wheel hubs, blue ano'ed Excel rims, fatbars, Grimeca hydraulic clutch. Neat stuff, and its not a freakin' orange KTM, I digress. I have been able to satisfy riding cravings with these bikes, but its not the same on a pinger. I need deep blue boom back in my life!!! I am still deciding what to do. Should I make it faster? Should I make it slower? Since I have to replace the crankshaft and the cylinder, I have the opportunity to build a big-bore / stroker. I can go all the way to a 565cc with a kit from Falicon for about $2500.00. I can also do a cheaper ($800.00) 502cc (yfz450 quad bb/stroker from hotrods/cylinder works) setup thats not nearly as good, but if I build a lower compression low-rev / easy-going chugger it shouldn't matter. I can also rebuilld it completely stock for about $700. Falicon makes some stuff in between thats cheaper too. I also heard to stay the hell away from wiseco crankshafts. I realized that I dont need a modified 450 for more power in harescramble racing, since guys on much smaller bikes go much faster than me. Mind power and Body power wins endurance races, not horsepower. I'm not out to break world records here, and I'm most likely going to get my ass handed to me on the track no matter what I ride. I just want something thats less hassle than a 14:1 race-gas-bonging monster that hates getting hot and bounced off of trees. I want to stop breaking stuff. What should I do? Reader poll!!
