What a dramatic transformation! Great build. The upside to that cracked intake valve is that it didn't happen during the summer.. that would have been a bummer.
Thanks Deafcafe, appreciate the compliments. And yes I agree, the timing of the valve failure was better than being in the summer. Although, I did just start a month long vacation at the time and was planning on riding it the entire month. Got one ride in before that happened.. Oh well. At least it opened up the opportunity to do some other engine mods that I didn't get a change to do before. The motor parts are at the machine shop right now as I type this. Once I get them back I will report with some pics of what more I had done to the motor.
Hey K_Kalynuik, I was looking to see if you talked about the air filter mod you did and only saw info at the end of your video. I like it a lot and want to replicate it on my 550. It seems like it would be a lot easier to get the carbs tuned well because you're using the Honda velocity stacks. Have you found this to be the case? Can you post any pictures of how you exactly did this and what K&N filter you used?
Thanks dude, totally sweet bike. I have this saved in my phone along side many others as inspiration for my build. Hope that's not creepy, haha!
Hey Dave, Thanks for the compliments as well. And no Not creepy at all to save a motorcycle pic in your phone dude, I have 100's of bikes on my phone that I have no idea who owns them. That's normal. Did you see my other pics on my BOTM thread? -
http://forums.sohc4.net/index.php?topic=121689.25 For the air box/air plenum. I don't have any close up pics of my personal setup at the moment, but check out this picture I attached. Its pretty damn close to how I did mine. I made a plate with a 2" hole cut in the center and 4 x 1/4" holes to mount it to the exisiting mounting holes in the air box. Then weld a piece of 2" pipe to the 2" hole you cut in the plate and bolt that whole unit to the air box. I used some sealer behind to make sure it was a tight seal. Then just get any 2" i.d. filter you want and mount it with a hose clamp. I don't remember the model number I got.
Also, because you retain the Honda velocity stack and stock air plenum, the tuning is a lot easier. Part of the problem with pod filters is the disrupted air flowing into the carb throat is not flowing smoothly due to the outside air turbulence when driving. The plenum allows the air to 'settle' down before entering the velocity stacks. While the larger K&N in theory allows more air flow for my open exhaust, big bore kit, porting and cam setup. TwoTired is the guy to talk to about the science behind the velocity stacks and airbox.
