Long time browser of the forum but this is my first post. I have to say to all, some of the bikes showcased on this forum are amazing. Great inspiration.
I picked up this bike earlier in the week. The engine is seized due to sitting up but as you can see someone had started to do some decent mods before it got pushed aside. The front and rear end are off a Kawasaki GPZ 900 I'm told and the tank is from a CB900 (or is it standard does anyone know)? The engine will be getting a complete rip down and rebuilt and I suspect I will go for the Cognito Moto GSXR front end conversion but I have to say I do like the monoshock conversion that was done (bar the wheel used). Love to hear what people think and their thoughts on the Monoshock / swingarm used. Hope to keep the thread updated with the progress as I go.
Now there is an idea.. I like the simplicity of the GSXR conversion Cognito moto offer but have mixed thoughts on the rear end. Leave as is or switch back to the twin shock :
+1 for keeping the ninja wheels. Different and unique. How many CB750s are running USD cognito setups? Plus the ninja 900 wheels would be perfect for a vintage race vibe.
Thanks all for your input. It will be a while before I make a call on the wheels and suspension but some food for thought there. Need to get the engine completely ripped down first and start that rebuild. I have since found out that the carbs that came with it are also off a GPZ.. 8)
I noticed they were CV flatslides and assumed they were off a GSXR slingshot. If they are jetted well, they should be a significant improvement on the street compared to stock carbs. Will be interesting to see what's inside that motor in terms of cam and pistons.
The mono conversion looks good ( so many are shite ), so does that front end. I dig the Kawi wheels and forks. Build that motor into an 836 and go hoonin'.
Thanks all. I must admit, there was a good job done on the monoshock conversion so part of me woudl like to keep it. I know the fabrication shop that did the work also so I know it was done right. I think what's putting me off currently is the colour of the wheels against the frame and swingarm.
Taking off the head this weekend to see what lies beneath! Pictures to follow.
Can you verify that the linkage and mounting points were installed in the exact location that they were in on the donor bike? If not, then no way to tell how good it is until it's ridden. Leverage ratios are important on those setups.
It looks like they added the top mounting point directly from the donor right?
If the motor is stock, I agree that a set of bigger pistons and a mild cam would wake it up. I just looked at teh intake manifolds and someone spent a lot of time on the conversion.
What have you been able to find out about its history?
Leave the frame color if it's not too chipped or pitted and get the wheels powder coated in Silver or white. You could maybe get away with bright yellow wheels if the tank and seat picked up the yellow in some way. Subtle? Maybe not so much, but could look bold.
