Hi, im rebuilding my first xs650 engine. Its a 477 with 0.25 pistons. The LH cylinder was burning oil, and on inspection the LH cylinder has some ring marks. You cant feel a edge on the marks and I've done 30 seconds of honing but don't know how much I can do. Can I have advice on what to...

Problem is I'm in the UK not the States. I have emailed 650 central to see if they can post out to UK. But not heard anything yet

Well, there are some really good threads on this, sounds like there pretty crap. I can get the Kleihins from Heidens for $420 or the VM34's for $700. Both come with all the boots, cables and filters. It just seems that the Kleihins are cheaper but you need to do a lot of tinkering to get them...

hi, what carbs have you decided on ?

Hi Really need a set of VM34's carbs.

Has anybody used these carbs, I was going to replace the stock BS38 with a set from Heiden Tuning KEHIN PWK 32mm. Before I spend the pounds I want to be sure. I have searched the forum and one reply was cheap rubbish

Right, Just done the following, Stripped and cleaned the advance mech and rod. Shortened the spring buy one curl. And they know snap back in position. One thing worries me, I have read that there is bit of paint on one arm and one on the sleeve. Thats not on mine so does that really matter...

Hi, Out riding the bike after a strip down and rebuild, engine was left. I have replaced the points, coils, resister, HT Leads and put new plugs in. Set the ignition timing and checked with the light. Took the bike out for a spin and for the first 5 miles it was spot on. Then it seemed to go...

On mine. The bike had stood for ages. After running it up. The exhaust is really oily and you do get a good drip from the exhaust. The engine doesn't seem like its loosing a cylinder. But when its hot it has a valve tap. Adjusted the valves as per spec. but it is worrying.

Hi, I live in the UK and need a silencer for a two into one exhaust silencer, chain guard and mud guard to get my bike through an MOT.

The carbs are linked with a black fuel pipe, the choke has one rod for the two carbs, and mine has a single throttle cable with a connecting rod between the two. When buying parts i have never seen anything that says twin throttle, has any one got any pics of a two cable set up. Also , with the...

Yes, lots of smoke when the mix screw is about 1/2 to 1 turn out, There is a idle scre on the outer side of the rh carb and another on the lh side of the right carb, should that be there ?

I'm hoping it isnt the rings, the engine is supposed to have been done by a po. Its probably the carbs, I have read the carb guide a few times but am struggling to get my head round the tuning. Its the first time i have ever really messed with carbs, more use to forklifts than bikes
