Even the yamaha which officially brands daytona kits for circuit use tells that using them leads to excessive wear and tare people modification is not oly gaining bhp's but at the cost of excessive wear and tare its better to keep things stock after all it would take more than 3 yrs of R&D by any company to make a new launch

Cool nice work to cleanse the forum and nice humor too in this thread !

I'm going to avoid this pros and cons debate about free flow filters but would like to share my own experiences with it. When I bought my Thunderbird I was not happy with the low end torque of the bike, having ridden a 74 bullet for most of my riding life prior so I thought I'll mod it and got me a k&n, bigger carb and BSA(cheap imitation) exhaust. Of course I paid no attention to rejetting or any of that but I did notice a considerable improvement in acceleration, heck I found the performance improvement quite adequate. Only if I gunned it I could smell burnt oil and the common overheating issues that everyone's familiar with. Fast Forward three years and right now my bike happens to be sitting in the garage as the division of its parts . I've blown two sets of pistons, knackered the crankshaft bearings and blown a hole through the exhaust, did I mention it was a cheap imitation? So you'd think that I'd wisen up and go back to using stock...heck no, the bike is just too much fun to do that. Instead I decided to dig deeper into what makes a bike tick. And that rabbit hole sure does run deep I must say. Up until recently I even flirted with the idea of running a DIY supercharger off the defunct starter gear, I even went to the extent of running a CG simulation to 'previz' the project...hmm, further investigation just made the whole project unwieldy and heavy and just not worth it. but it was loads of fun while it lasted anyway. I might get back to it when I have another bike to ride around on and know enough about what I'm doing but for now its shelved and wisely so.

Its pretty common knowledge that race engines do run free flow systems (filters and exhausts) and equally common knowledge that race engines are stripped down and rebuilt after pretty much every race weekend. They can afford to and more importantly they need to. For us everyday users careless modding can and in my case has proved to be quite expensive but on the flip side its also made me more acutely aware that such endeavours need that much more attention, not to mention education. Its not enough to just fit it and forget it. Things like checking the oil, spark plugs, tightening the chain, etc. have to become a weekly routine and cannot afford to be taken for granted.

I'm not much of a speed freak, I get my kicks out of shaving inches off my pegs, the long hard way but getting my hands dirty with a bike has now become my new favourite hobby, and personally I'm the better for it. Guys like Joel have taken this passion to a whole other level and made a career out of it not to mention history, all the while leaving the factory guys scratching their heads, so go figure.

And oh, yes a tuned RTR can smoke a stock RD, if Joel was behind it, I'll believe it...

Happy modding...

dear highbrows
what do you have say about opening up inlet & outlet valves?
&
is there any catalyst for performance enhancement?

I would not comment on anything about the performance, but this part had me rolling on the floor!!!
