How would I remedy that? Buying a smaller wheel?

A lower profile tire;is that tire what they run on the DOHC donor bike front ?

The DOHC runs a 100/100 19" it seems

Look at the tire for signs of rubbing, like shiny areas. Pay attention to the sides where the fender stays are.

Will do!

Collect some black dust and burn it, feel the smell. Rubber?

Good idea!! Here's a pic so you can see what I mean

Yeah honestly now that I look at it again I feel kinda silly thinking it was

Aren't you glad you didn't rush to buy a new master cylinder?

Pielz · « **Reply #33 on:** July 08, 2020, 09:12:09 PM »

I am! My cheap Chinese perch will live to see another day! Haha.

While you're here I should ask, when I pull the front brake, it sorta pulses? Is that a warped rotor? It stops fine but I can feel the lever sorta moving in my hand.

Brake action is smooth though. Braking power doesn't pulse

scottly · « **Reply #34 on:** July 08, 2020, 09:19:36 PM »

Could be a warped rotor, or maybe it's from the tire rubbing?

I'd say your single disk is not strong enough

Pielz · « **Reply #36 on:** July 08, 2020, 09:35:10 PM »

It's gotta be one or the other I guess. Maybe some day I'll do a front end swap from a 750F so I can go dual disk. For now at least I have some things to check. I'll use an index like a paper clip taped to the fork to try to gauge if the rotor is wobbly. And try to inspect for rub marks. I'll update!

If your bike had duel discs it's for a reason my friend I'm a bit stuck trying to find duel discs in UK for the front end of mine the problem is the bolts go through the wheel and hold both discs togeether I can find single disc in UK burn it not go intnl to be strong enough

Pielz · « **Reply #38 on:** July 08, 2020, 09:45:50 PM »

My bike is a K to begin with so it never had dual disks.

Would certainly be nice if it did though. Hope you find some on your quest! If I liked the way it looked and didn't care about period correctness, I'd do the GSX front swap I've seen folks do lol

hill29493 · « **Reply #39 on:** July 08, 2020, 09:47:50 PM »

It might not even be your brakes tbh you might not have a proper seal on your manifold

Sound like you need new exhaust gaskets

I would of done the same but wanted to keep the style of fork so I put a 750fa front end on my francenstin cb

I just installed a delkevic 4into1 with new gaskets. I guess its possible I messed up but I don't feel any puffs of exhaust by the head. Also the black powder just brushes off. It doesn't smear which I guess now that I think about it, should have tipped me off to it being rubber not brakes.

Post a pic of your Frankenstein!

You might just wanted to check if your manifold is not to small. Iv ordered a 4in1 for a cb900 for a 650 port which I need to michean down to fit the ports hopefully I'll find out when thay come if not it a nice way to waist £499
