Thought I'd post an update to inspire other mechanic wanna-be's like myself. My inspiration came from a friend of mine that's a mechanic and lots of tech support from you guys here at TT. So far I've torn down my 426 and now building it back up putting in new piston, rings, gaskets, valves and seals. While I was at it I upgraded to the '03 450 auto de-comp exhaust cam. Refurbished the carb as well with all new o-rings, vent lines and upgraded the AC pump cover with a Quickshot. Now that it's 90% back together I have to bring it back to the dealer for a valve adjust and then the finale re-assembly here at my garage. I've done 3/4 of the work myself and am grateful for the couching I got from my mechanic buddy. Not only has it been very satisfying to try something so daunting but now I can really appreciate how everything works in the bike. Damn...I can't wait to ride this thing, it's gonna scream.
