Finally had a chance to play around today. So, I made the most the oppertunity and ripped the stuffed motor out of the yellow bike and replaced it with the motor from the dismantled KR1 I bought from Dave the other week.
After giving the rolling frame a quick pressure wash, I put in the good motor, and proceeded to chase electrical gremlins. After changing almost every electrical component (apart from engine components), it turned out to be a problem in the wiring harness which I swapped out as well. The first start took about 3 kicks but only ran on 1 cylender and feul started pissing from the carbs. Pulled the carbs apart, quick cleanout of the passages, and it started first kick and and ran like a dream. It sounded so sweet through the 1-S pipes (and an open airbox

) as I gave it a quick rev
Still got a lot to do before it's ready for the track, but getting it running has certainly helped with the motivation.
The plan is to put it together as an intermediate track bike so I can get a feel for things while I take my time building the special. That one will get an RGV 17" rear wheel, R6 rear shock, R1 USD front (with custom adjustable rake triple clamps), tuned motor (Keeping it @ 250cc), hopefully source some PWK35's for it, and fit some heavily customised fairings from various donor bikes. Once the special is ready (may take a while), the intermediate bike will get a good resto and go back on the road.
Well, that's the plan anyway......
