I think that maybe coming on here and giving advice on a bike then admitting that you know #$%* all has gotten you in a bit of trouble. The majority of guys on this forum are great and only to willing to help anyone with these bikes. I think your comments about "Honda knew what it was doing and an altered engine will never be as reliable" didn't help either. There are some amazing guys here producing modern parts for our engines, billet blocks, modern alloy pistons, heavy duty engine chains, improved guides and more and i was going to comment in that thread because i am building a 1000cc engine that i am expecting to be better than original in almost every way, now it is costing a pretty packet but thats my prerogative. Settle down mate and enjoy the wealth of information,this is really the best resource on the planet for these bikes and after a wobbly start you are more than welcome to be part of this eclectic community. I hope nothing here has offended you as that was not my intention.....

Mick, thanks you have not offended me.
I DO have some experience with bikes.
Truth is I know a lot of stuff someone with no experience can use. And I said the truth -- people don't like buying modded bikes.
That is *generally* the truth.
Not *always* the truth.
Now I want to show you that I am a rational person. I am going to point out an exception to the 'most buyers want an un-modded bike' -- there is a '73 cb750 with 49,781 miles that just sold on ebay for......$4500!!! A 73 with HIGH miles. AND IT IS HOT RODDED:

Bid history: 16 bids

Has a big bore kit, re-done all over, etc.
But MOST OF THE TIME people want an unmodified bike. I didn't knock modifiers or builders and say 'All builders do a bad job and end up with unreliable bikes.'
I never said that! Some folks do a great job.
But.....if you have ever looked at ebay listings for a bike, and compared what an all stock example goes for and what a modded-out example sells for -- the modded bike almost always (emphasis on "almost" there) ALMOST always sells for less than the bike that is unmodified and in stock trim.
There is a PERCEPTION that modified bikes are not as reliable. Your point that SOME are MORE RELIABLE because of the skill of modern builders. DEFINITELY TRUE ON THAT ONE. Point is well taken
BUT MOST MODDED BIKES are not engineered for reliability like they do at the factory. Here's why.
1) skill of the modifier varies GREATLY
2) first a custom part A added to a bike, then a custom part B, then a custom part C -- all 3 parts from different 'custom parts' companies -- were NEVER TESTED RIGOROUSLY together, *on the bike* -- in the Honda factory. You start combining a bunch of unrelated aftermarket parts from different manufacturers on a bike with the work being done by a hobbyist mechanic -- THAT IS HOW MOST MODDED BIKES get put together.
It is an accurate observation to say 'There is a PERCEPTION that modded bikes aren't as reliable.' And the above is part of the reason why.
And I never said "I know nothing about this bike" !! I know LOT about my sandcast. It has tons of stuff in common with cb400f I owned, kz1000, kz900, etc. that I have owned and worked on. I'm qualified to give advice.
I rebuilt the top end of my '77 kz1000 back in 1979 with a big bore kit.
I just finished taking a '78 kz1000 that had not run in 13 years and got the motor going. BIG JOB THERE. Valve issues, carb issues, electronic ignition issues, wiring issues, lots of problems. Shes going great now!
My 69 cb750 has a LOT in common with other 4 cylinder 4 strokes I've owned.
And has a lot in common with bikes in general. And while I'm not a pro mechanic, I have done a noteworthy amount of work on ALL SORTS of motorcycles.
I am QUALIFIED to give advice and if you find something I say that is not correct because of something I dont' know that's particular to my cb750, heck man if you can politely correct me, and emphasize politely as in "you're close on that advice, Chortling, but on this bike it's a bit different' --
that's polite. Saying 'You dont know nothing about this' aint polite.
I will still give advice on the cb750s if I think I can help and if I'm missing something by all means politely let me know, I DO IT THAT WAY TO LEARN!
