Nothing unusual cropped up in this restoration so I haven't posted about it before. It's another frame-up rebuild starting with a shot blasted and powder coated frame.
It's got a US silencer on it which has quite a deep throated note but is not offensively loud
Just had to go to our local seaside resort of Exmouth so took advantage of the lovely weather to drive along the promenade and took some pics whilst I was there.
The tide was in and lots of people enjoying a variety of water sports
Sadly our recent storms seems to have stripped this part of the beach of most of its golden sand
The TTR is a genuine UK model but I managed to buy the imported-from-the-US exhaust recently and it is in really good condition so fitted it instead of the standard UK one.
However, although it started and ran great, the exhaust was crackling and popping a bit on the over run and there was a definite whitish tint inside the exhaust port.
No other mods have been done on the TTR. The carb had one of the standard UK setups of #48 pilot and #142 main jet. I put in a #50 pilot and raised the needle two clips and it runs even better than before and the crackle has gone.
It does make me wonder how and why the US TTRs run on #137 main jets if mine was a tad lean on #142

I would suggest that the fuel quality in the US/CA is VERY poor. Ethanol is used in all blends apart from racing fuel (some states may differ). However, the real reason I think is the emission issue. That said, most seem to find that using a larger main jet simply makes it run too rich (so we are back to the poor quality fuel).
