[QUOTE="tony91, post: 1115377, member: 28106"] [B][U]Initial Mods[/U][/B] MX Bonz Airbox fix 13/49 gearing Rad Valve Extensive carb tuning PC pipe and PC Shorty Straight C-12 [B][U]Recent Mods[/U][/B] Eric Gorr Overbore (265) and "Mo betta" Porting RC valve tuning All steel clutch plates Flywheel weight Stock Pipe and PC Full length silencer 13/48 gearing [B][U]Future Mods[/U][/B] PWK FMF Fatty V-Force I started with the gearing, pipe and silencer, Rad valve, and straight C-12. With those "bolt-on's" and lots carb tuning, I had a really fun, capable bike to ride. I got a little bored and was leaning towards a 4T. As a last ditch effort to stay away from the darkside :p , I sent my jug off for the overbore and porting mods. It came back an absolute beast! I couldn't be happier with Eric's work. It's stronger off the bottom with plenty of over rev. I started fooling with the RC valve, got it to where I liked it (11mm). I liked the mid-range better with the stock pipe and felt no bottom or top-end loss versus the PC pipe. I tried the shorty too which seemed to kill the mid-range and over rev. To help with traction and to tame it just a tad, I went with all steal clutch plates and a 9oz FW weight. You will lose some "feel" with all steal plates, but it did help smooth things out a bit. And along with the FW weight, traction is improved. I need to work on my jetting more. I think I can improve there. I'm looking for a deal on Fatty as Eric recommends it on his overbore jobs. Also, do a search on the PWK carb swap, lots of folks here swear by it. I’m looking for a deal there too. I had it to do all over again, I would go with Eric's work and the race gas first...then play with the bolt-on's. And I really can't say enough about Eric's mods....no 4T for at least another season... ;) [/QUOTE]
