Big blowback.
http://tv175.wordpress.com/2011/01/13/c ... -blowback/

What I did miss was the drill out and the insert of a new M10 stud in the case that has weakened it and led to a crack. So much for original, this engine is far from original and untouched, its rebored to 1st oversize and the casing is bored out to take M10 to hang the exhaust up. This has weakened it and a crack is showing.

It’s in need of a rewelding and aluminium build up if it’s to be used again. In Sweden all craftsmanship work it extensively expensive and the cost can easily pass that of a new engine block. If I can find a good quality TV175 one that is. Most ones on the market are GP ones.

And what will it all cost to re weld and rebuild is the question right now, there are still some SIL engines in stock. It might even be cheaper to get one of those and change all the known inferior parts.

This will require allot of planning and thinking on what to do. Suddenly I realize why this bike has been stood for the past 26 years.

One question while searching. Is the TV175 engine block the same as all S3 except GP? Can I use a LI engine case and throw the TV parts I have in? Is there a differense between 125, 150, 175cc?

Whats smalblock and largeblock?

there is an alloy putty called devcon. I've never used it and I think you can pick it up for around £25 on evilbay. Im told once the tins open thats if done so make sure you have all the jobs you want to do with it ready. I assume you fill the hole let it set then retap it.

check it out and if its a go'er pop some pics up....if anyone on here has used it let it be known

There is a crack in the block on the inside on the one the stud goes in. Dont know if helicoil or devcon kan fix that.

grinding the alloy away and welding up in the uk retapping will cost around £25 this is the best way,is this the only damage ?by repairing you will keep your origional number on the case,you could use any li 1-2-3 case or sx gp and rebuild your bits into it.

Here I got quotted £300.
I would like to fix it and reuse everything since I would like to keep the matching numbers and the bike as close to original as I can.

you could ship the case over her then!

£300 ? thats taking liberties you'd be as well posting it over here getting the repair done and having it sent back to you.

It's an expensive country.
So, you think I can devcon or Helicoil it myself in spite of the crack?

In Sweden an electrician takes round 60 to 100 £ just to look at your problem.

I wouldn't know were to send it!

no to devcon and helicoiling,weld it only!
