Just read that in it's entirety. 7 years for what I would class as murder. This country is totally insane.

Not only that, even though he's sight impaired, they are going to give him his licence back!

That's fantastic mate, and the bike looks better than factory!

More done. Can't shift the shock mounts or the torque arm bolt, but I did get that snapped bolt out of the master cylinder!



Found another snail too....

All that I can say from the fact you got 120 wet and 90 dry on a compression test is...that you are probably losing compression in the bore/rings/piston combo.  Cheers

Are we talking bog standard or modified, restored or original or barn find?  There's no point trying to set up an unknown quantity, as you could end up chasing your tail unaware something's been modified in the bike's history.

If it's just a tune up you're after come along to the monthly meet - there's plenty of experience available.

You could even trailer or van the bike to the meet for a (free!) appraisal on the best way forward.

An update for you all.  I oiled the left cylinder lightly and then did a compression test.  BAM! 120 psi.  I then started it to burn off that oil and it ran quite poorly again .  Recheck compression after it cooled off and it is back to 90 psi.  It would appear to me that I might have poor ring clearances even with new ones fitted and a fresh hone.  I also swapped heads with the right side just in case there was a crack in the head.  Am I on the right track?

RD Racing / Re: TD3 TR3 style seat hoop
« Last post by 5port on Today at 06:00:55 PM »
You can get a good general idea from the spare parts diagram, try TD3 on CMSNL or other online parts.  Basically, the hoop tube is partly cut away underneath where it sits ontop of the frame rails but, it is complete tube where it runs in the rear shock mount gussets and, out into the loop.  Overall, it is quite simple but, would be difficult to get right without a lot of work.  Also, the dimensions need to be right.  If you can do frame modifications, I get the feeling it might be best to look at the drawings then, make the Tank/seat/shocks fit as you build it?  Cheers
