Do you know if the 250 can be bored to 350 or if i can swap a 350 into it?

I'm leaning more towards the first one. The third one is the second one's setup but fairing removed.

I am not sure about boring a 250 to a 350. The engines do look very similar so a jug swap might be possible. The engines look similar wnough that just bolting a 350 in looks possible.

I could take mesurements if you needed them.

What i should have said was that the bolts i loosened all fit a 9/16 socket. I'd be concerned if they weren't metrics. Once i get into my new house i will dive in with a service manual.

From what I've read, the 350 engine has a beefier transmission. The extra torque wouldn't be too bad either. I'm wanting optimally the 350 with the short stroke crank which can rev up to 10,000 rmp.

I might take you up on the measurements offer at some point.
This here will pretty much be my build thread for this bike.

had two of them, 250 & 350. both were great machines and would run 90 all day long. the 250 had performance head and ran quicker than the std head 350. do you have the fsm?
no problem going to the next jug up.

So if i get a 350 jug and piston it will bolt right up with the 250 head? I want to make this a rev happy hot-street motor. Im also going to give the bike a diet and play the Power to Weight game. Never going to race it but want to pay tribute to the race history.
Any directions or advice is appreciated as this is still a very new project.
I've also been taking pictures at every turn for reference and to document changes.

I've been busy moving and working like a slave in a bullet resistant vest but I finally had time to work on the Sprint.

The wife was getting her hands dirty too


First weekend (last month) in the house I tore my ligaments in my dominant hand at work so I took it apart with one hand to this point.


Pulled the side cover, full of cobwebs


Dropped the motor with one hand working and no jack. Painful but worked out.

Also a note before disassembly,
i tore down the carb and cleaned it out, changed the spark plug and new condenser from harley, fixed the points, verified spark, rigged up a gas system and started kicking furiously.....
Nothing....
With a jello leg i called it a night.
The next day im on my way out the door to get sandpaper and thought "let me check the oil on this"
I open up the oil filler spout and a frothy mess like the melted slurpee from hell began hemorrhaging from the hole as if under pressure. Covered in brown i put a turkey tray under and watched it fill. When it was done i opened the drain plug and let it all out. It stopped dripping with the tray filled to 3/4 capacity!
Apparently the thing had been stored outside and the crankcase vent funneled enough water in there to achieve a ratio of 1 part oil, 5 parts water for a total of roughly 2 gallons (oil capacity is 2 quarts).
So i pull the rockers, head, blow out water from the oil tubes. Discover the inside is immaculate. Not a single spot of corrosion.
4 hours later i reassemble, fill it with 1 quart marvel and 1 of 20-50 conventional, kick it with a hand full of throttle and it purred like an angry kitten at 3k rpm for a while till i ran out of gas.
It was squirting oil from the pushrod tubes so i drained it and then proceeded to document the build as shown above.

I love the old small race bikes like that everybody was racing in the 60s. Dick Hammer won the lightweight 250cc GP in 63 and 64. He had a wheel come off a few years later faceplanted at speed and wound up in the hospital about a month. As soon as he got back out, he was racing again. Back in the day men were still men.

Dick died of cancer back in the early 2000s.

Anyway, that's cool. Those little bikes have some history behind them.

So its been a little over a year from my original post so time for a build update.....

Pics 1,2,3 show the stock handlebars. I cut them up to weld up custom cafe bars. My first welding project. Then I cleaned, scrubbed and scraped the engine cases the best i could over winter. When i had my water working this spring i degreased the motor and hosed it off. New gaskets for top end and carburetor.

Pics 4,5 show it as it sits now in my garage. Tank and seat/fairing are hand laid fiberglass from Glass From The Past. Need to troubleshoot a fuelling issue and will install magnito ignition and solid state electronics. Maybe fabricate a center stand.
Once i finish all the troubleshooting and have a running and operational example it will be torn down for sandblasting and painting.

Total spent on parts/shipping: $914.64
