Yep, Halco Tuning, the much-missed UK XS specialists. I dug out the original UK owner's purchase receipt for the bike when he bought it in May '99 but it doesn't give any clue as to what they did to the bike. The silencers are definitely theirs. The engine is certainly very sweet. The bike cost him £1800 - a lot for then I reckon. I see I acquired it in Sept '04 for £1300 with 10,000 miles indicated & it's just turned 15k now. It was fate that brought it to me - the original owner had worsening MS & couldn't safely ride any longer so had agreed to sell it back to Halco but Tony Hall tragically died before the deal could be finalised so it was advertised locally & I snapped it up. I fell in love with it on the 20 mile ride home. Sold my KH400 as a result (shouldn't have of course). Nothing has gone wrong apart from a misfire which was a dodgy connection from the ht lead into the plug cap. Starter recently stopped working but haven't checked that out yet.
I have recently become re-enthused to do some mods to it. May change the bars (again) for something more Triumph/BSA shape, bit lower but similar width. I'd quite like a shorty front mudguard but don't know where to source one (must be chrome). The seat could do with re-covering, can get a cover but might see if a local upholsterer could do it in leather. Might go to a Smed Speed oil filter conversion. Would like a softer feel at the brake lever so a smaller bore master cyl. perhaps from a Yam trail bike might do it. Also fancy a drilled brake disc. Plenty of fun to be had.
