Cam Chain Question for XR400SM in Thailand

[jamiep]

Hi Guys/Girls,

I'm currently travelling around SE Asia on an XR400SM and a week or so ago when i was leaving Malaysia for Thailand i noticed a small clunking noise in the engine it wasn't very loud but didn't sound right but after the bike warmed up a bit it stopped so i carried on. I woke up the next morning and when i started the bike the noise was there again but slightly louder but again stopped once the engine warmed up a bit so continued on to find a more populated area i might find a descent mechanic. I made it to Phuket and when i started it the next morning the noise had become a lot worse and i didn't think it would be wise to try and ride it Bangkok plus it's a nightmare up there with all the protests going on. I found a million little bike shops in Phuket but none that made me feel comfortable about letting pull my engine apart after talking to them and seeing the state of the workshops. After asking around a few expats and trying the internet i got recommended to some guy an English guy used but he only rode a scooter so i wasn't totally convinced but decided to go down to chat to the mechanic who said "yeah sounds like your Cam Shaft" but wouldn't know until he pulled the engine apart and once he did he wouldn't be able to put it back together even if i didn't want him to fix it till he could get new gaskets from Bangkok but this could take a month as they may have to order from Japan. Walking down the road wondering what the hell i was going to do next i stumbled upon a slightly bigger bike shop with a much better looking work shop and quite a few big bikes out the back so i went in and asked the guy could he take a look and after a couple of calls said it's probably your Cam Chain so he pulled out the tensioner made a bit of an adjustment and just like that the noise was gone. He tried to find me a new tensioner but parts for an 07 XR400SM aren't exactly high in demand here. He then gave my bike a full look over, tightened a few things, lubed my chain and topped up my brake fluid and changed the Oil then didn't charge me anything except for the Oil

So now i'm planning on ordering the parts from back home (Sydney) and was just wondering if there is anything else i might need when replacing the Cam Chain and Chain Tensioner as in are there any other pieces that you normally need to order when changing a Cam Chain. I just want to avoid waiting several weeks for the Cam Chain to arrive and then finding out i needed some special little rubber or a seal that i missed and having to wait another 3 weeks.

Thanks in advance,
Jamie.
