Hi Guys

I need a bit of advice about a problem with a TT600E which I have just bought.

Here we go..When I start the bike from cold it smokes really badly and smells of burning oil but after a few minutes it clears up with know sign of any smoke what so ever.

When I bought the bike the engine was warm so as mentioned I didn`t see any problems with it.

There is no oil leeks or strange noises coming from its engine and the bike pulls like a train when ridden.

It is a 2001 model and has only covered 7800 KM,I have all of its Mot`s to back the milage and the bike is in mint condition showing no sign of abuse.

What could be wrong with it?

Surely it doesn`t need a top end rebuild at 7.8K

Can a dodgy engine oil valve cause this to happen?

Does anyone also know of any Yamaha Dealers in the UK that would be willing or able to get hold of genuine parts for the TT600E.Spoke to my local one today and he told me "thats what happens when you buy an import" he wasn`t interested in helping me with parts.

Did a bit of research today and found that Germany is the place to live if you own a TT/TTR/XT ETC.

Any help will be much appreciated as I`m starting to regret my purchase.

Thanks Guys.

Mmmmmm I,m no mechanic but I would think it would be a valve seal and maybe oil is draining in to the piston overnight and getting blown out when starting.............but that is just a guess,hopefully someone will be along soon who actually knows what they are talking about......it should not be burning oil like that at such low mileage,are you sure of the mileage?.....

Just read this

As a weight-saving measure, Yamaha fitted the XT with a chrome-plated aluminum cylinder liner (the same as on the TT600) instead of a more-conventional iron liner. We've heard reports that some TT cylinder liners get out-of-round easily, causing oil consumption to go up. Some TT600 owners even have resorted to installing iron liners. When asked about the problem, a Yamaha spokesman said out-of-round liners and oil consumption shouldn't be a problem if the bike is broken-in carefully.

Hope thats not your problem cos its a complete strip down if it is,well the top end anyway...........hope I,m wrong...

Valve stem oil seals. As said above, a little oil leaks past them overnight, and gets burnt off when you start it from cold. Had exactly the same symptoms on my 86 XT.

Previous owner clearly knew about it, thats why it was warm when you went to see it.

Try Fowlers in Bristol. 0117 9770466. They wont do anything without a frame number, so make sure you have it to hand when you call. They've always been good to me, and my bike is an import too.

I don,t know about your tt but my old 86 tenere s head cannot be removed with the engine in,maybe the tt is different and you can remove the head and have it overhauled by an engineering company if you are not too mechanically minded.

Some one will know ....just remembered I have a tt 2004 manual here and this is what it says,I hope its the same for your year....

The cylinder head, cylinder, camshaft and piston
can be examined with the engine installed by
removing the following parts.
• Seat
• Fuel tank
• Rear cowling
• Carburetor
• Exhaust pipe

Hello Chaps

Thanks for your advice,I do appreciate it.

Thought about valve stem seals but wouldn`t the oil that had run down overnight get burnt off in a matter of seconds when the engine is fired up rather than taking minutes?

Also regarding its cylinder liner being out of round,wouldn`t this have shown up when the bike was young and repaired under warranty..hope it isn`t that as it sounds expensive just after buying the bike.

Also surely the engine would smoke all the time with an untrue cylinder?

This clears up after a few minutes.

Just checked my oil tank level and it has not dropped since last night so it seems that the engine oil valve is ok,don`t know if this would have made the engine smoke anyway.

Regarding the bikes milage,I have checked all of its paperwork plus the bike and there seems to be no indication of clocking,I mean even the footpegs still have paint on them,it has its original discs plus the seat cover has no wear or shiney areas,seems to be original..7,800 km.

Had my bro-in-law round earlier to have a listen to the TT and he told me that the engine sounds sweet and has no piston slap or cam rattle what so ever and he has been around dirt bikes for nearly 40 years and was once South East Trials Champion and Expert Class 250/500 MX rider so I tend to believe him,he mentioned guides and seals.

Looks like its going to be a strip down but was wondering how I am going to get hold of torque settings for the engine when Yamaha UK will not talk to Import Owners..Any Ideas?

Yes will ring Fowlers..Cheers Mate.

Thanks
Paul.
