I think I see the problem...

I ment carb lol

I was typing quick that's all

It's generally considered good manners, or forum 'Netiquette', to post an intro in the relevant section, before starting on the requests for help... especially when all you have done in this particular case is merely announce that there's an issue with your bike.

Think of it as walking into your local biker bar, where no-one knows you, and you just speak that exact same post in a loud voice...

The crew here are brilliant, friendly, helpful and knowledgable folk... but also mercilessly sarcastic toward 'One-Post Wonders', who generally come along expecting/demanding free solutions to bike issues and then vanish off without a word of thanks. It happens a lot.


This is a social community, so do the social thing - Pop up an intro post in the New Members section, tell us a bit about yourself and you'll find a far friendlier response!!

Okay well I apologise for that but if there is anyone having a problem simular to mine in the future I be happy to help them back as I say a biker always helps another bike I'm sorry if I have upset a few foke on here

Don't get me wrong - We help in spades... But like most Bikers, such things usually start with "Hello..."

Could do with a bit more history

How long have you had the bike

Was it running fine for a period before

Is the fuel fresh

When was it last serviced etc etc

Well I've had about a month it ran okay for 3 week and then started to get problems but their all sorted expect that it won't start from cold with full coke on

Choke I ment lol

It turns out the there is next to no compression in both cylinders so it's a total engine rebuild

But thanks for all your help guys

Ouch!

I know but I love my yamaha even though I have only had it a month 750 pound it's costing do you think that's a good price

Ouch!

Whats the mileage?

Second hand engines are rare too

Its labour charges that are a killer, can you do it yourself?

20,000 miles but I think the other owner ran it with no oil

You will save a fortune if you can do it yourself, obviously rebores and such are an outsource item but most of the strip down and rebuild you can do in the garage or even on the side of the road if you have to. How low is your compression compared to the manual measurements?

With a bit of luck you may have to just change the piston rings and thats just a top end rebuild, the shit on the stick moment is if the barrels have worn away and you have to try and find replacement oneswhich is not easy nor would i think they are cheap.

If you can do it yourself then you will save loads of cash as the lads have said above, just take your time and read the manual word for word and don't rush it. If you need a manual i know someone who has one (wink wink)

Well their rebuilding the whole engine I can do the basics that's all lol
