Tankbreather

Hi Guys... hope you don't mind if I gatecrash this party. I've followed all the posts in this thread and I'm really impressed with all the good advice and wisdom coming forth.

So at the risk of portraying myself as a complete idiot, I'd like to ask ask an out of the ordinary question.

I've got an old 150RR and the RC valve is way past its expiery date.... doesn't perform anywhere near what it's supposed to - in fact I've already disconnected it. I'm not a speed freak so I don't mind not going over 80km/hr. I've set the RC valve to what seems to be an optimum position for upto about 65km/hr, but after that I get a terrible "roughness" coming from the engine. I know it's to do with the RC valve because I've fiddled with the positioning with cause the onset of the roughness to vary. I've got about 4 months left in thailand before I go back home and don't really want to fork out 10k to replace the RC valve setup.

My question (finally) is, is it possible to replace the cylinder with one that does not cater for an RC valve. Or is there some kind of adaptation I can make so that I can take it out completely.

I'll forgive your laughter at my questions, but would really appreciate some serious comments.

I need to have some aluminium welding done to my motorbike engine.

Does anyone know or someone or a company that does this type of welding? I've searched on the internet but couldn't find anything.

I'm in the Klong Tan (near Ramkamhaeng) area of Bkk, but anywhere in Bangkok would be ok.

Thanks to all who replies.

I've been asked to proofread a thesis of 40 pages. I would have to correct the spelling and grammar. I'm assuming the English would not be too bad.

Does anyone know what the current going rate is for this kind of work. This is the first time that I'll be doing it?

What would be a reasonable length of time to do it in?

Thank you.

Does anyone know if Kota Bharu has the same requirement. I'm going there this weekend to get a tourist visa.
