Thanks for the welcome and the advice about the forks. This is why I love forums, lots of good advice!
I did originally intend on having the frame chromed but I decided powder coating the frame in a metallic black would work better as was advised to chrome the frame properly some of the welds would have to be redone or at the very least cleaned up some and there would be the risk of it chipping.
I started off on an Aprilia RX 50 (single cylinder two stroke), then on to a Kawasaki GPx 250 Ninja (parallel twin four stroke) and then the DT125R. I have had it off the clock two up (private road officer!) and the powerband seemed to not drop off till the redline, I think it has been ported by its first owner as it really does seem to be very peaky. This is with the reed switch still in place behind the clocks. It has fully functional YPVS which I think is from a French bike as it has the markings 3RM-F on the YPVS cables. Cylinder head has 3BN and Y-2 and the engine number starts with 4BL.
It has some other number as well under the engine which has been etched in which is not consistent with Yamaha, it's SSN23. I have no idea as to what that's for as I've not seen it on any other DT. Stan Stephens number maybe if ported by a pro??
I've had a look through the exhaust and it looks like it's had some porting done, not the usual rough ports.
After I got the DT I went on to a Yamaha TDM850 (parallel twin four stroke, induction sound like a snorting hippo and exhaust like half of Subaru Impreza) then a Yamaha TDR250 (parallel twin two stroke) and then a Suzuki GSX-R1100 (four cylinder four stroke, modified for drag racing and sprinting) and a KTM 640 LC4 (single cylinder four stroke. Sounds like a V1 flying bomb on full chat, and wheelies for fun if ham fisted) then on to a Honda CRM 250 (single cylinder two stroke) and a Kawasaki Zephyr 1100 (four cylinder four stroke, looks like the old Z900 of the 70's but much beefier).
I still have 5 bikes including the DT, but the DT is the one I most enjoy probably as it gave the biggest impression as after years of watching McGrath vs Carmichael it was like having a motocross bike for the road. Sure the CRM250 was faster and the KTM beats both but the DT definitely at 17 was like living the dream lol. I feared I'd be looking back with rose tinted glasses but I had a go on one a few months ago and it still made me grin from ear to ear.
