Topic: Sport cam?

[NickC]

but now how did you know it was off that much? is there a way of measuring it?

When I swapped over to the 650 Tach, it dropped by about that much

wow...thats huge! well looks like im not going to have a proper reading then!

you know I have a cb650 just sitting in my shop i have been debating fixing it up but I think i may strip it. so i might as well just stick the cam in my 550

[cb650]

What model is it?

[jaymz]

it is an 82. or at least thats what i remember. It is in a pretty sorry state at the moment anyway and i already have 7 complete bikes in the garage anyway.  what is everyone running the tappet clearance at? I am thinking the factory clearance on the 550 would be fine but I want make sure that it doesn't cause enough heat to swell too tight when it gets hot

If you have a good motor in the 650 you might consider installing the entire unit rather than just the cam. . . .For the tach issues, if the 650 and SOHC 750 share the same ratio then there should be a wide range of  gauges available to keep a classic look.  Another option might be to install a custom gauge face in the stock 550 tach that corrects the readings.  Have fun.

In 82 there was still 2 diff models.  Standard or the nitehawk.

Sorry it is not a nighthawk. standard cb650. probably should have been a little more clear about that. I have considered swapping the motors but I just did an overhaul on the 550. I may just steal the cam and take the motor out and rebuild it for a spare or continue with the thoughts of restoring it.  either way i am ganking the cam. I have been thinking about it for a while and after reading through the testimonials I have the motivation to move ahead. Some day I fear my wife is going to make me start clearing out the stable though.

If you decid to part the 650 let everyone know.

[jaymz]

will do

since were kinda on the subject of tacks and what not, does any ones know of a digital tack/speedo that can be installed on a 550? im thinking that i want to go digital with this.

There are actually alot of universal gauges on the market these days acewell and koso to name a couple reading rpm from a wire to the spark plug and a magnet on the wheel to read speed just like a bicycle i have never used a universal tach so i couldn't tell you how reliable one would be but seeing as it just reads from the spark I couldn't see it really being off. I have used a few universal speedos that used magnets on the wheel and I never found one that was very good with the always changing temperatures in the Ozarks. I think the acewell line might actually have a regular speedo cable option        just a quick google but I came up with this one pretty reasonable price i think   not my style though    http://www.electrosport.com/products/product-detail-2253.php?source=googlebase
