Oops is this right?

Guys I think ive figured out why bike wasn't running right if I was to take variator/gear casing off and rev the bike even with back wheel on floor should the belt move
And it wobbles abit
Il upload a video in a sec to show you all

 

It says this video is private!

Sorry mate sorted it now

 

OK, no expert, but your variator is not adjusting with revs and your clutch is not biting and trying to turn the back wheel, with the revs you were using I would expect the scoot to be shifting along the road, or trying to.

Watch this

May not be the same engine but gives an idea.

So I suspect two things, knackered clutch and stuck in low gear variator.

Adrian

Or this one

 

Didnt think it was right the fact it wasnt shifting/moving
There was loads of burnt oil in there aswell... and the variator fan plate has been wearing against something

 

I would be tempted to say that the nut on the variator has been is loose at some point? Check there is no free play on the finned part.

I say this because I changed my variator because the nut came loose, the finned disk moved outwards and the fins rubbed against the metal plate on the inside of the gear case/variator/kick start cover. Look on the inside of the case for marks where the fins have been rubbing.

Just wondering if you put or anyone put extra spacers or washers into the variator shaft to help keep it in lower gear for longer?

What I would start to do is take the clutch and variator off the bike and inspect the parts for wear, check the rollers for jamming and being an odd shape where the surface has rubbed off.

On the clutch check for the pads that they have enough friction material left and that they are not coated in oil.

With regards to oil there should be none in there, no parts in that side use oil, a smattering of grease on some bits like the kick starter but no oil. If everything is coated with oil suspect a seal has gone on either the engine crank or from the rear gearbox.

Adrian

p.s. I would also suggest that the engine mounts have new rubbers fitted, it may be an optical illusion but looking at the second picture I would say it needs them.

 

The gasket for the cover is dead and theres been oil coming from airbox could that of leaked into casing
Theres been no washers added at all

 

think me needs new one
Rollers seem fine

 

Certainly seem to be bits missing from that.

Not sure on your keeway hurricane but if you search for service manual there are downloads, just found one at 18.8 meg.

I am guessing it is 50cc 2 stroke.

Oil coming out that much from air filter is a problem, but I can not guess why it is happening. There is information saying that the 2T oil is regulated by pump but why back into the air filter!!!. Worth a read if you do not have it, It is English/Chinese but most is understandable.

Have fun, time for sleep here.

Adrian

 

Yeah mate got it on phone already lol think I might just read through it how would I know which seal has gone

 

Looking at the case gasket it could be that if it is not stopping the oil from the air filter box seeping in.

If the clutch friction material is covered in oil then you need another as I doubt it would clean off properly, it would soak into the material.

If you are having problems with oil from the airbox I would suspect a deeper problem with the engine/2T pump. It may be time to sit down and assess costs to get the engine up to good condition or if is the best time is to seek a replacement engine?

Perhaps some of the more knowledgeable on 2T engines can post responses.

Found a replacement engine the bloke wants 71 quid just gotta sort out delivery

 

£71 that's a random amount.

 

Ok that sounds good, I replaced the engine in mine and it cost 100 so you are doing well. Hope you had the assurances that it works OK and mileage etc.

Sometimes it is just cheaper then buying parts individually. If it gets fitted and runs OK, then you can at leisure clean up the old bits and use it as spares to keep the bike going.

Adrian

 

Yeah sent him best offer of 70 and he rejected with counter offer of 71 lol and yeah think il put this engine in and slowly do mine up tuning parts 70 kit etc ready to drop back in eventually

 

I worked it out parts would cost about 60 then if oil seal had gone it would only fuck up again so rather spend a bit extra and get complete engine and carb trying to get the shocker off him aswell lol

 

You've possibly just jinxed yourself

 

Well think il be ripping the old engine to bits and seeing whats fubar and learning whats what so prepare for a fair few questions lol
