Hi just picked up a 1978 tr77 starts lovely and idles nicely BUT after a few minutes it will pick up the revs to almost maximum without any input without sounding dense where do i start?

Hi all .. I've managed to almost resolve the clutch issues.. but I've noticed the back cog for the kickstart gear ⚙️ is very damaged And no longer meshing looks like the circlip was never replaced 🤦‍♂️...how do I get it out? It's behind the gear selector finger ! Do I have to remove the whole gear selector shaft or is there an easier way..

Yeah have since ordered that little brass pressure pawl also a new spider as the centre looks worn in motion trial's recommended a 20 mm spider (base to tip of the leg) And to grind down to 15 mm instead of the standard 13 mm many thanks for your help

I can rock the bike And click up thro the gears And back down I'm pretty sure Now that it's a very tired clutch as plates look IN pretty poor condition 😔

Thank you so much for the PDF 👍

I can feel the mechanism trying to activate the clutch 👍 I actually can't start And change up to a high gear thank you for your help

Anyone still alive on here that has any information on the clutch assembly? *******o clutch will not disingage ( stuck in gear) all gears selectable... Have soaked the basket in petrol and doesn't seem to be sticking.. really need an exploded diagram as I feel a crucial part maybe missing.. engine was rebuilt by someone else.. even the tiniest information would be great 👍
