Wicked Kawasaki F7 175cc Thread

I picked up a pair of project bikes on Craigslist recently and I've begun the search for information on these Enduros. Looks like there have been a handful of threads in this section, but I thought it would be nice to have a general resource for anyone interested in, or working on their own project.

So this might be considered the 'mega-thread' or 'threadfest' for anyone working on an F7.

Obligatory picture of a Nice Looking Restored F7 (Not mine...)




So anyone out there? Whatcha working on? Just want to brag and show us your immaculate garage queen, fully restored bike? Got a sweet parts lead?

Here are the existing F7 threads in this forum:

There is also pretty decent information hiding in a Yahoo user Group:
https://groups.yahoo.com/neo/groups/...kisingles/info

Parts diagrams are available in a handful of places, but here is a quick link to one that seems to work fine:

This guy seems to have a lot of relevant information to vintage rotorary Kawasaki's in general... Not necessary the 175 in particular:

72/73 Project Bikes

As I mentioned I picked up a pair of these bikes to try to get in running order and looking presentable. We'll see how far I get, considering most of the important stuff came to me in boxes.

Here they are coming out of the truck at the homestead


Boxes and loose parts, Also go some parts in a 30 pack (beer) box - No beer included =[


Took a couple minutes to collect all the loose parts into something a bit more suitable


Holding area until I see what I'm working with engine-wise


Ideally I'd like to move all the good parts I have over to the silver bike and keep it as original as possible. The red one has obviously seen some repainting and sticker-ing, even though it appears to be in a little better condition. The guy I bought them from said that he bought the pair as a project and actually had the red one running, but one for a few minutes before the piston broke and seized it up. So I started with 1 free engine and 1 stuck engine.

I already tore the stuck one down, and pulled out the broken piston pieces - to and the jug looks fine still. Got quite a bit of cleaning to do as they are both caked in dirt. They guy did have the clymers manual with them, so I'm not toally in the dark. I also found a pdf of the Kawasaki manual thru MY 1973 on the web...

Though as you know I've listed it locally. I blame my KTM

I've got an old school Clymer manual at home for it as well. Kinda cool that they spec out how to hot rod the motor. They give you dimensions for the rotary valve and a few other trick things.

A little progress on one of the 2 engines. Had a few beers with a buddy and tore it down all the way. Since he wasn't heavily invested in the project the parts ended up all over the workbench - but I figure I have 2 manuals and an example engine to put it back together, so I'm not terribly worried.



Trying to figure out the best way to clean these up. I thought about buying a parts washing station, but settled on a plastic tote with about 1/2 of degreaser in the bottom - and an array of wire / plastic / and tube brushes. took maybe an hour to get 1 side of the crankcase looking decent.



You can see how dirty it was compared with the uncleaned side. But there is still a fair amount of dirt / grime stuck in the little corners and odd shaped parts of the transmission area... It will do for now, or until I figure a better way to get at the small spots. Slow going, but seems like a necessary step

Indeed a good looking '72

Speaking of seals-

Would it be a major mistake to not replace all the crank case seals while I'm this far into the engines? I was considering not since they 'look' okay, and I can't find a single place to buy all the required seals.

Tried to breakdown my 2nd (Donor) engine this past weekend.

The flywheel would NOT come off the shaft. Not sure if I was doing something wrong, but the damn thing would not budge a bit. I ended up destroying my puller/bolts - the center pin yielded and bent off in the dimple in the end of the shaft. NO LUCK.

This was my setup:


I need to get to the transmission gears to replace 2 broken pieces in the other engine...

Mine was the same situation. I think it's the 40 years of being in 1 location it's entire life. It doesn't want to move. I'm trying to remember, but I may have used a little heat or some other form of persuasion to get mine off. Maybe spray with some penetrating fluid?

Just don't thread the bolts in too far & hit the stator. DAMHIK.

Subscribing just because this was my first bike, mine was a 1972 yellowish color. I would love to get one again some day just for nostalgic purposes.

I tried the torch and a bit of strategic pounding and that didn't help either. I think you are right, after 40 years, its basically like 1 solid piece of steel.

Thanks for tagging along. It'll be slow going, as its just a bit of a side project... but Hopefully I'll have a farm bomber on the other side.

Subscribing because I just bought one. Getting cylinder work done now and will hopefully have it running soon.

I decided to pull the motor out of my F7 last night. I figured if all else were in decent enough shape, I'd try to find a stator setup to mod in from another bike to get mine going.



I figured why not pull the head.....


Welp, there goes any plans to make this motor run again.

Time to find an alternative route to take.

Andrew

ps - I need to put that motor in a plastic bag. My garage has a hint of 70's premix to it now.

Hmmm... doesn't look good. I see your flywheel came off, doing better than I

Do you still have the carb assembled? Do you happen to have a pic of that you could post up?
