100MPH SR250 First Start

Join us for the first start of the #100mphsr250 !
Spoiler alert, this was a bit of a fail. The engine is now teared down and handed in to a machinist for oringing.
Before tearing down the engine, the bike was ridden up and down the street and it showed a lot of potential - it pulls more like a 500 despite the leaking gasket. However with this extra power, the clutch slips like crazy, despite fresh clutch plates and heavy duty springs. We are looking into potential modifications to avoid this. Keep checking in to catch the next update - hopefully a sealed engine and working bike!
Happy wrenching and happy riding!
- Jadus

Hey Jake - the bike looks stunning. Never saw anyone on KZbin ever put this much love into an sr250.Makes me want to keep mine for decades to come!

[@jakesapparel]

Great vid - Always good content from you Jake! :) Love it!

[@JadusMotorcycleParts]

Cheers man! Great store you've got :)

[@mickbetts2176]

Great looking bike Jake, I'm sure you'll sort it. At least you don't have to take the motor out for the head gasket!

[@Nathan-wf3fr]

Beautiful machine. Nice work!

[@khunangkaro]

I have one rewired.... But now in disarray, no spark. Must change the black ignition electronic box. I left it sitting idle, because driving ISUZU D-MAX is so much safer in Thailland's crazy scary traffic conditions.

Please keep it up, small bike go fast!

Hi Jake, looks great I am sure that you will get the 100 miles! The sound is amazing. Witch shocks measure do you have?

[@JadusMotorcycleParts]

Thanks man! Those shocks are YSS and are 340mm eye to eye :)

[@deligiannisgiorgos9038]

Hello Thanks for your great effort. All the parts I bought was excellent 👌 One question; could this bike be functional without a battery? thanks

[@JadusMotorcycleParts]

Thanks for the feedback! Yes you can run without a battery but you will need a large capacitor instead. But they are not much smaller than a 4cell lithium battery so not much point in my opinion!

I’m jealous of his fuel canister, American ones are plagued by difficult to use safety devices

[@bartstaton2059]

the headgasket would explain the compression issue! ill be waiting for the updates!

[@JadusMotorcycleParts]

Exactly! This was like a 'duh' moment for me afterwards ;)

[@sydney0596]

when is the battery relocation bracket back on stock ?

[@JadusMotorcycleParts]

All parts are in stock and available from our reseller: modelikocaferacers.com/gb/248-yamaha-sr-250 :)

[@BikingChap]

I'd have thought the lack of pressure initially was down to a closed throttle.

[@JadusMotorcycleParts]

Unfortunately it was a leaking head gasket that was the culprit.

[@Shsishsgsk]

Can't find this same model in the Malaysian markets, I was wanting to get one to customise into like a retro chopper, this one or the xv250 but Welp can't find this one.

[@JadusMotorcycleParts]

I think the SR250 was only available in select markets.

[@khunangkaro]

​@@JadusMotorcyclePartsI have one. Near Ubon/Mukdahan. Thailand. Never saw another one.

[@ciettck1602]

Xe của tôi nó k có cần khởi động. Đang bị hư đề :(

[@Miniscapes515]

Did you use a kick start from a tt250? I dont recall sr250s having kick start

[@JadusMotorcycleParts]

Correct. The bulk of the parts are from a wrecked 1980 XT250 but some of the small parts had to be sourced from CMSNL.com

[@Miniscapes515]

@@JadusMotorcycleParts nice! Think I want to do the same. We got your seat and alot of your other parts. A few years ago. Life happened and bike got put off. But back at it now. I'll send pics when its all finished this summer Thanks

[@caponira]

Hi, where can I get those rear sets from, cheers.

[@JadusMotorcycleParts]

Hi! The brackets are custom but the rearsets you can purchase from ebay. Search for: TEC Universal Folding Alloy Rearset Kit

[@caponira]

@@JadusMotorcycleParts Thanks mate.

[@ms.nonisnon8948]

How high is the rear shock?

[@JadusMotorcycleParts]

340mm Eye to eye :)
