Been messing around with the barrel tonight, it was one of those '99p bargains' off fleabay and was advertised as a LI150 barrel and piston so I thought I'd give it a punt and won this
Bit of a rusty dog to be sure and it at some point someone had indulged in a spot of home-tuning though I use that term lightly
As you can see its had a bit of a butchering at some point, its just a 150cc barrel of unknown origin, the castings quite rough in places and I'm wondering if it could be one of a batch of poorly made 150/175 barrels that came into the country years ago. what I know about these top-ends is that the quality of the steel was a bit crap and so they wore out pretty quickly
The fat ringed piston which came with the barrel
Now I plan to take the barrel to 175 and match it to a suitable piston. The problem I have is that the inlet and exhaust ports have been taking out too far to be safely run without the risk of the rings snagging on the ports. I was planning to use a wire-ringed SR175 piston to get around this but they seem to have had a bad press. Has anyone ran one off these pistons without any issues?
If the quality of the barrel is a bit wank or I bugger the piston up then I haven't really lost too much cash wise. I'm planning to run it using a 22mm Delorto carb and standard exhaust because I have them already and I quite like the tractability of a standard pipe over the more revvy clubman. Any tips, info, opinions with be gratefully received. Paul

Can't offer anything really except that it will be interesting to follow your build if you could do some sort of blog as and when. Good luck with the build mate, I'm sure you will be just as happy with it knowing you haven't had to pay ££££
