DoctoRot wrote: The kz750M is different in many ways from the 76-79 "B" The head-stock rake on the M is 28.5 degrees while on the B it is 26.5 degrees. The M has more fork offset, and has leading axle forks while the B has standard forks. all of this will make it handle "slower" than the B models, but be more steady at higher speed.
The offset fork reduces trail, which makes the bike steer faster. That's why such forks are used in conjunction with a more kicked out head angle, which slows the steering. Swapping the 16" rear rim for an 18" will raise the back end of the bike up and steepen the steering a little. I'd put that mod on the "to do list" for sure.

HOLY CRAP!!!! Are you kidding?? If not, you really need to do a LOT more study on the subject because you are VERY confused. Except for the fact than both machines have two wheels there is very little remotely similar between the two. You may want to attend a flattrack race or two so you can start to appreciate the level of effort that goes into building a flattracker. Below is a good example of each. Ed

I believe you are correct. I know for sure in Maryland you couldn't and wouldn't want to license a flattracker for street use. Ed

Yes, they're quite acceptable. I don't have many miles on them, but will say that they are a vast improvement over stock. Of course that's not saying too much.
There is someone out there who will rebuild them to a really decent spec. I'm drawing a blank on the name but if you search the forum you're sure to find it. I'm happy enough with them as they are and not planning to do anything like that right now.

You can register pretty much anything here for daytime use, and it doesn't need a huge amount of lights for a full registration.

You are correct, but I should have specified that even with the leading axle forks the M still ends up with 112mm of trail while the B has 105mm. so the M in theory should be slower to turn. And yes get rid of the 16" wheel. that's what i did on my kz750G

A flattracker has ZERO lights, no charging system, no front brake, painfully loud open exhaust, no fenders, etc., etc. Could that actually be licensed, and if so would you want to use it on the street? :blink: Ed

The lack of front brake and loud exhaust.would mean you couldn't get it registered in the UK, weirdly you can have no lights.650ed wrote:

No, I wouldn't want to ride it on the road, I've got old and like my bikes civilised now, nice comfy seat and sensible riding position.

Good luck riding a XR 750 on the street. If you look at the picture both the gear shifter and the rear brake are on the right side so that when shredding a left dirt track corner you can access both controls. :side: Takes a bit of getting used to. :S

Rustyhama wrote: Hi and welcome. I've done a cafe racer out of a CSR - the little brother of yours, the 305. I agree with a few other posters on here re the shape of the frame. They drop down in the middle then kick back up towards the rear - not conducive to the straight 'bone line' traditionally associated with the cafe racer style. I used side covers to cover it but if I was able to weld (and with the benefit of hindsight) I probably would have cut off and replaced the frame rails with straight ones. You do then have an issue with rear wheel clearance. Mine looks ok still with the 16" rear wheel, maybe because it's a smaller bike. I also shortened the forks on mine which makes it steel quicker which suits me for round town. As some others have said that bike is no treasure so chop it but please don't butcher it! It's still a KZ!

Thanks for the feedback. I just read your whole build thread and all I can say is "wow!" You did a brilliant job with that build. Thanks for the inspiration.
Regarding the frame, I am planning to modify the rails I think. I'm a metal working hobbyist and my cousin is a licensed welder. Between the two of us (mostly him), I think we can do it up right. That said, I really really like those side panels you made for the electrics box. I will almost certainly be hitting you up for feedback as I get into my build.
Step 1 though is getting the old girl running. 20+ years of sitting idle is no good for a motor of any kind.
Cheers!

Held a steady idle on full choke only and died immediately if I moved the choke or tried to rev the motor at all. I'm thinking this is due to the fact that I was running with no airbox at all and to me it seemed like the carbs could do with a rebuild. Sound close to right? :huh:
