Thanks Guys, was awesome to be able to watch my engine build, can’t wait to get it back in the bike👍👌 Big shout out to Brad and his team at Scooter Street for their great service and Professional advice, keep up the good work

@scooterstreetau 3 года назад

Thanks Tyrone. Best part of the job is to build on the engine when it is out of the bike. Thanks for you support and stay in touch for an update.🙌

When I modify an engine to perform more than the stock build,, the first thing I do is remove the oil pump and start mixing my own fuel.. I dont trust them small buggers :P Great video,, like always :P

@scooterstreetau 2 года назад

We have many customers who share the fear with oil pumps... We prefer to run them on road registered bikes, provided the system is intact. Oil pumping is something we recommend to regularly check. On race bikes we've built over the years, we have always run premix. Its just a preference thing, not worrying about the pump vs. the convenience of not having to premix. Thanks for watching🎅

Please do a legit tuning vid and onboard ride vid with speedo and gps video. love seeing what different builds do. Good work as usual.

@scooterstreetau 3 года назад

Yes that would be fun, this job was an engine build only, sent to us in a box from Melbourne about 2000kms away. Unfortunately we did not have the entire scooter. Thanks for comments✌

how often should you replace the crank seals? And should you change them if you say, replace your crank?

@scooterstreetau 10 месяцев назад

Well you can change them at any time the engine reaches 10'000kms. Or, you can change them when they fail and leak or certainly when you change the crankshaft. When we carry out a service we inspect the seals and look for misplaced or leaking around the seals at which point they would be replaced.

@ayyvee5757 Год назад

Hi scooterstreet. Is the stock oil pump enough for a 70cc kit ? What do you recommend when not premixing ?

@scooterstreetau Год назад

Yes it is, ensure the oil pump is working and all of the associated parts are in good order, check it often as part of your routine maintenance.

@dexietyy7922 Год назад

It is because it mixes at 50:1 so 100ml oil to 5L petrol in premix terms I just put a small capful of oil in my fuel tank just to be on the safe side

Love it, but would like more of the yamaha jog r

@scooterstreetau Год назад

No Jog R in Australia, we only have CY and CV.

@stephenbrown40 Год назад

would you find it easier to put the circlip in without the cylinder sat on top of the piston and getting in the way? Ive only ever used the piston in bore method on four strokes where its the only option due to fiddly rings. Its usually really easy to squeeze the rings together by hand on a two stroke due to the cylinder cut outs at the transfer entry. Just a thought. Loving the vids :)

@scooterstreetau Год назад

We did it this way for the video, we would usually fit the cylinder while engine still in frame. See our other vids, Thank you for watch and comment👍
