Great thread this, awesome to follow it. You are a clever man Charlie, well as clever as a guy that rides a bike with one wheel :pinch: :ohmy: :laugh: or maybe that is clever :whistle:

Calm down Mick only stirring you, dont drink any petrol, I dont want you starting :laugh: :laugh:

I just ran into a major hurdle, I need a 75-80 tooth 428 sprocket, don’t care what it fits as long as it is steel, the custom sprocket boys only make 500 series sprockets, I can’t find anyone that makes custom 428 sprockets . I can get a 57 tooth, but I don’t need the 220kph that would give me,lol

Looks good mate.is the last pic a hint to bring those tyre levers around.
Guessing you cut the old one off.

It took me 15 minutes with two little screw drivers, I wouldn’t know how to use tyre levers, I’ve always done it with screwdrivers, the front tyre was even easier. That hardest part about the rear tyre was figuring out the bead locks:)

Been workin my tail off on the FZwhy, most importantly I added a bit of go fast colour to the Yamaha frame:) I lubed what was left of the the needle bearings in the rear suspension, turned out all of the spacers and bushes needed to retrofit all of the TM parts to the FZR. Installed the front and rear suspension and even mounted the new front tyre. Tomorrow I will anneal the rear wheel so I can hammer out some dents, and then I can mount the new rear tyre, I’ll also shop around and find the largest 428 sprocket I can so I can cut the centre out of it and weld it to a new centre I’ll turn out on the lathe to match the rear wheel. I’m having a ball with this project, I can’t wait to ride it, it should be as dangerous to ride as it looks, but then, I am a bike slut, I’ll ride anything with two wheels, and on occasion, one wheel:) I’m looking for a new front FZR250 sprocket, a straight set of low rise handlebars, a new 428 chain, and four FZR250 carby rebuild kits, just incase anyone has any of that just laying around in their spare parts pile:)

Had to cut out the frame to clear the Ohlin rear shock.

Got some swingarm angle going on there. How close are you to the TM angle? Will the chain pull over the guides be OK?
Love the build, very good. you will be a tap dancer on the gear change to keep it in the power but that adds to the fun

The chain should just touch the front of the swing arm with the bike unloaded, a 57-60 tooth sprocket should help with clearance as well as improving the woeful low end torque this bike has. It should bring the 180klm top speed down to about 130klm, that should be plenty with knobbies in dirt,lol:) should sound pretty wild, 4 cylinder, 16 valves, flying through the forest at 17,000 rpm.

Almost finished now, not! I’m hoping to finish welding it up today.

Finally, an update on the FZwhy. I Cut out all of the suspension mounts in the FZR to make way for the TM250 suspension. A whole lot of measuring and head scratching ensued. I Had to keep all of the geometry in place so the suspension works properly, had to keep sprockets aligned while allowing for chain clearance. Also had to keep room for the battery and try to leave as much room as possible for a fuel tank. Trying to do all that and build in a lot of strength left me scratching my head for two weeks. I think the final product will fit the bill ok, I will only loose about five litres in the fuel tank, and the suspension works nice and smoothly, and everything lines up just as it did on the TM250. There is heaps of work to do, but progress should speed up now that the engineering is finished.

My RG250 scrapper has fought me all the way LOL

I have had to make numerous bush’s and spacers . . . .

Good the front end was simple, you are motivating me with mine

Pezz

As it turns out, I need to make one spacer for the front suspension and two little ones for the rear. How is your bike coming along.

Now that looks like a whole lot of fun!

What gearing are you running??

Not enough, I need a 100 tooth sprocket for the rear, this thing doesn’t begin to make power until 10,000 rpm, but it should sound pretty wild tearing through the forest at 17,000 RPM, twin cam, 4 cylinder, 16 valves, it sounds like a formula one car,lol

[CharleyMember]

I only found out today that Pezz is doin the same kind of conversion. I did a few hours tinkering last night and the FZWHY250 was born. The front of the TM250 actually fits perfectly, but the rear suspension is goinng to take a bit of work with the sawsall and tig welder, and ill have to modify the fuel tank as the rear shock will be right in the middle of it. Oh, and I guess I should contact my son and let him know that he donated his FZR to a good cause, maybe I’ll let him know sometime in October:)

What a fantastic ride, and a fantastic bunch of guys, I had a ball, thanks for everything. I met so many wonderful people, and at 100kph on some of those roads, the pucker factor was so high you couldn’t have driven a needle up my butt with a sledgehammer,lol

Oh, and TB, um, after giving me a hard time about Harleys going home on Trailers all weekend, I believe I seen the NEW Yamahahaha, loaded up on a trailer when I left, you didn’t think I would let that slip by did you:) You know they make Gel filled sheep skin covers for tender bottoms:) hehe

Cant wait to see all you guys again, even if it is just for a beer in Mic’s shed, thank you everyone.

Here is a video of the last test run I did on Friday, I changed the rear sprocket from a 45 tooth to a 51 tooth. It really flys, accelerates until you back off the throttle now where before it died in the ass after the first 20 feet.

Well, it was quite anticlimatical, after everyone telling me it looked like pain on one wheel I was sort of expecting a steel bucking bronco, but after dumping the clutch a couple times I relised the whole thing was quite sedate. I need a larger sprocket on the back and to move the bars back to the rear setting and if thats not enough I’ll raise the front skids a few inches to increase ground clearance a bit.
