I'm guilty too. But at least what I got out of my extreme true duals was almost penny for penny what it cost me for my Dragos 2:1. what a kick *** sounding and performing pipe.

go for it. I did mine this winter with Jamie's 107 and heads. make sure you have the right tools. the service manual, patience and a torque wrench are your friends. Feel free to PM me with any specific questions

if you can do the cam you can do the heads and jugs. Other than the stupid circlips on the pistons it's pretty damn easy.

+1

It's the cam chest that mildly frightens me. Oil pump alignment and all...

Taking the heads, cylinders, pistons off.. piece of cake.

Thats true, but consider trying Supertrapp Megashots stepped 2:1:2, look like true duals but you have the X pipe. Theyre a bit pricey though $2k, I got lucky and found a super deal. My 103 with them just was dynoed at 124/121

... definitely alot said for a proven build unless money is of no concern. There are plenty of FM 107's out there with stellar repeatability in numbers ... 107", Level B's, CP 10.75's (10.6 actual), 777's, FM TB port and polish and PD's here ... 115rwhp/124rwt ... couldn't be happier unless I went to a 117" or 120".

Frank Drago did NOTHING like FM does to the Delkrons. Frank is a pro.

Update.. I went for it and did the 107 build from FM, piece of cake. Watched the Videos on the FM site which basically walks you through it. The only real PITA is the piston wrist pin clips, they send new ones and a special little tool which did not work for me, even watched a video from there website. Improvised with a small piece of PVC pipe.

Got her running yesterday, got about 60 miles on, no drips, weird noises so it seems all is well. Definitely need a new tune from FM but decided to start autotuning the map I was running with the 103/SE255's. Thanks all for the advice. Cheers.

Congrats ... feels like a different bike, doesn't it? Get her broke in and post up some numbers. What are the details ... cams, compression, heads?
