I got around to fitting my manual CCT last week. The non-tensioner side of the chain seemed too loose with the auto tensioner fitted and the plastic c…login to view the rest of this post

Mine did exactly this. It turned out to be copper corrosion of the earth wire beneath the insulation where water/salt had penetrated. I had to cut the…login to view the rest of this post

Thanks Pete, you are spot on regarding the jacking threads. Looks like I need another stripdown and inspect the bearing holder and cases. Something ju…login to view the rest of this post

Next question: The gears now turn smoothly, all select fine. Whilst assembling the input shaft, I noticed the large bearing holder with the three torx…login to view the rest of this post

I just took a look at a few Youtube repair videos and they all seem to have the shielding on the outside face away from the gears. Looking at the oil …login to view the rest of this post

Gents, I have replaced the faulty gear clusters in my spare 4XV engine, however the output shaft is a bit of a mystery. I have replaced the big output…login to view the rest of this post

Also try CMSNL as they tend to have stock that nobody else can get.

My 4XV has always made similar low speed, part-throttle noises to yours Moise which I also blamed on the Exup with occasional stuttering when picking …login to view the rest of this post

The 4XV is a doddle to work on. I stripped and rebuilt mine after buying it as a project bike (aka a shed). Don't be afraid to get spannering, there i…login to view the rest of this post

Didn't the SP run a slipper clutch as standard ??

Despite a reasonable weather forecast, just got drenched in a hailstorm walking the dog. Dont think I'll bother getting the bike out today. If you are out, have a good run and ride safe.

What time in the afternoon?

I might drag the 4XV out and pop up for a brew.

Cheers Pete, that makes perfect sense. Looks like I've bought another lemon then. :angry-screaming: Any chance I can bring it over for you to have a l…login to view the rest of this post

If you removed the servo motor for the exup, the tacho will probably 'dance around' to show diagnostic error codes. It does on the 4xv models, also fo…login to view the rest of this post
